ASUS has released BIOS updates for all of its LGA 2011 X79 motherboards that add support for Intel's upcoming Ivy Bridge-E processors. The update enables enthusiasts to upgrade from their existing Sandy Bridge-E CPU to an Ivy Bridge-E model which adds marginal improvements in performance and power efficiency. Supported processors include the Core i7-4960X Extreme Edition, Core i7-4930K, and the Core i7-4820K. According to benchmarks by Tom's Hardware, the top-end Ivy Bridge-E i7-4960X exhibits up to 30% improvements in performance per watt along with being slightly faster in multi-threaded performance than SB-E. Of course, single threaded performance was shown to be similar to that of Sandy Bridge-E but slower than Haswell.
All of ASUS' X79 boards (including the ROG Rampage, TUF, and P9X79 series) will be getting a BIOS update which will be made available for download on the company's support website or via the individual motherboard product pages. The following chart indicates the motherboard and associated BIOS version number that adds support for IVB-E.
|Motherboard||BIOS Version Supporting IVB-E|
|ROG Rampage IV Extreme||4206|
|ROG Rampage IV Formula||4004|
|ROG Rampage IV Gene||4206|
|TUF Sabertooth X79||4104|
To grab the update, head over to the ASUS support site and type in your motherboard model name to get the appropriate BIOS file.
Will you be upgrading your LGA 2011 rig to Ivy Bridge-E?

Tagged: Richland, overclocking, LN2, APU, amd, a10-6800k
A Finnish overclocker known as “The Stilt” recently pushed an AMD Richland APU to 8.2GHz using liquid nitrogen. In doing so, The Stilt broke the world record for APU overclocking, besting his previous overclock attempt.
Specifically, the chip was a retail version of the AMD A10-6800K “Richland” APU. It was overclocked to 8203.01 MHz with a 130.21 MHz base clock and 63x multiplier. Even more impressive is that The Stilt managed the overclock with less voltage -- 1.968 volts -- than his earlier (and lower) overclock. For comparison, the earlier overclock brought the A10-6800K to 8000.48 MHz using 2.008 volts.
The system used to overclock the APU included an ASUS F2A85-V Pro motherboard, 8GB of AMD DDR3 Performance memory, and a Radeon HD 7750 graphics card. The overclocker used liquid nitrogen to cool the APU while the GPU was left at stock settings and with its default air cooler. The RAM was overclocked to 2083.6 MHz with 10-11-10-27 timings.
In all, it is an impressive overclock considering all four CPU cores were left enabled! More details along with validation of the overclock can be found over at HWBot.

Tagged: SDP, haswell
Intel has just lowered their lowered thermal expectations for Haswell if, of course, you use SDP as your metric. Scenario Design Point (SDP), as opposed to Thermal Design Power (TDP), describes how much heat dissipation is required for the product at some, usually underclocked, performance target. SDP does not need to affect burst performance, however, as the chip can still up-clock given some extra headroom.
While we don't know OEM partners, Intel could be green, with HP Envy?
It describes long-term cooling requirements, not instantaneous power draws.
In terms of SDP, Intel expected to ship 6W products based on their 4th generation core architecture. Today, Intel announced a limited stock will dip below that target, capable of just 4.5W in waste heat. OEMs who purchase from this limited binning will be able to include Haswell in even thinner active or passively cooled designs.
Intel has not described exact specifications, partners, or shipping dates.

Tagged: Samsung, mali, exynos
Exynos, the line of System on a Chip (SoC) products from Samsung, were notably absent of ARM Mali GPUs. This, apparently, struck concern over how viable Mali will continue to be and whether ARM will continue to lose designs to competitors such as Imagination Technologies.
Then Samsung announced, Monday evening for us North Americans, the upcoming Exynos 5 Octa Processor will embed six ARM Mali-T628 GPU cores. The T628 GPU cores are capable of OpenCL 1.1 and OpenGL ES 3.0 standards which should allow applications to offload heavy batches of tasks, such as computational photography processing, with high efficiency and performance.
The Exynos 5 Octa contains four ARM Cortex-A15 cores at 1.8GHz, supported by four additional Cortex-A7 cores clocked at 1.3GHz. These processors are currently being sampled and should be produced in August.

As we have been discussing the 220W TDP 5GHz AMD FX-9590 recently it seems a good idea to show what level of performance you can expect from this chip. Hardware Canucks had a chance to benchmark the performance of this chip using both synthetic benchmarks and some gaming tests. When they tried to overclock the chip they ran into difficulties with not only heat, as you would expect but they also ran into an issue with power, they maxed out the amount that the board could provide. Single thread performance is not up to par with SandyBridge-E but in properly designed multi-threaded programs the performance is impressive, though perhaps not for an $800+ chip.
"With the FX-9590, AMD has taken their Piledriver architecture and pushed it to the absolute limit. By running at an astounding 5GHz, this new CPU is the fastest in the FX-series stable."

Tagged: xeon, Ivy Bridge-E, Intel
Tom's Hardware acquired, from... somewhere, an early engineering sample of the upcoming Core i7-4960X. Intel was allegedly not involved with this preview and were thus, I would expect, not the supplier for their review unit. While the introductory disclaimer alluded to some tensions between Intel and themselves, for us: we finally have a general ballpark of Ivy Bridge-E's performance. Sure, tweaks could be made before the end of this year, but this might be all we have to go on until then.
Both images, credit, Tom's Hardware.
When browsing through the benchmarks, I noticed three key points:
- Single-threaded: slightly behind mainstream Haswell, similar to Sandy Bridge-E (SBE).
eight cores(Update 1: This was a 6-core part) are better than SBE, but marginal given the wait.
- Power efficiency: Ivy Bridge-E handily wins, about 30% more performance per watt.
These results will likely be disappointing to enthusiasts who seek the highest performance, especially in single-threaded applications. Data centers, on the other hand, will likely be eager for Xeon variants of this architecture. The higher-tier Xeon E5 processors are still based on Socket 2011 Sandy Bridge-E including, for instance, those powering the highest performance Cluster Compute instances at Amazon Web Services.
But, for those who actually are salivating for the fastest at all costs, the wait for Ivy Bridge-E might as well be postponed until Haswell-E reaches us, allegedly, just a year later. That architecture should provide significant increases in performance, single and multi-threaded, and is rumored to arrive the following year. I may have just salted the wounds of those who purchased an X79 motherboard, awaiting Ivy Bridge-E, but it might just be the way to go for those who did not pre-invest in Ivy Bridge-E's promise.
Again, of course, under the assumption that these benchmarks are still valid upon release. While a complete product re-bin is unlikely, we still do not know what clock rate the final silicon will be capable of supporting, officially or unofficially.
Keep calm, and carry a Haswell?

Tagged: Intel, BGA, Bay Trail, haswell, roadmap
There has been a ton of BGA processor stories over the past year, with the most recent being that Intel will not be releasing the BGA-only 14nm Broadwell processors next year. It is not all bad news for BGA fans though, because Intel is reportedly introducing new BGA versions of Haswell-based chips late this year and in the first half of 2014.
According to a leaked road-map, Intel will release three new Bay Trail based BGA chips under the Pentium and Celeron brands by Q4 2013. Additionally, next year the company will launch three high performance BGA-only Haswell-based processors.
On the low end, Intel will launch three new Bay Trail-D based processors. The J1750 and J1850 will be Celerons while the J2850 will have Pentium branding. The specifications are available in the chart below.
|Base Clockspeed||Cores / Threads||Cache||GPU||GPU Clockspeed|
|Pentium J2850||2.4 GHz||4 / 4||2 MB||Intel HD||688 / 792 MHz|
|Celeron J1850||2.0 GHz||4 / 4||2 MB||Intel HD||688 / 792 MHz|
|Celeron J1750||2.4 GHz||2 / 2||2 MB||Intel HD||688 / 750 MHz|
For the enthusiast crowd that favors small systems (like Intel’s NUC), the company is releasing three new Haswell-based BGA processors under its Core i5 and Core i7 branding. Specifications for these high end chips are located in the chart below. Interestingly, these Haswell chips in a BGA package come with Intel's much faster Iris 5200 processor graphics. A high end desktop CPU SKU with Intel's GT3e (GT3 GPU with embedded memory) still eludes enthusiasts, however despite the BGA packaging. Note that the BGA Core processors are not coming until at least next year, according to the roadmap (which does note that dates are subject to change).
|Base Clockspeed||Cores / Threads||Cache||GPU||GPU Clockspeed|
|Core i7 4770R||3.2 GHz||4 / 8||6 MB||Intel Iris 5200||1300 MHz|
|Core i5 4670R||3.0 GHz||4 / 4||4 MB||Intel Iris 5200||1300 MHz|
|Core i5 4570R||2.7 GHz||4 / 4||4 MB||Intel Iris 5200||1150 MHz|
There has definitely been resistance against Intel’s BGA lineups by the enthusiast crowd, for fear that customization and DIY abilities would be hampered and that BGA would take over and displace LGA (socketed CPUs). In this particular case though, I think the new BGA processors are a good thing and so long as there continues to be LGA options for the DIY and enthusiast crowd, I look forward to seeing what platforms these new BGA chips are used in and what motherboard manufacturers offer with them (if they are even offered at retail at all, and not just to OEMs).
I think a BGA version of a desktop CPU with Intel's fastest GT3e processor graphics would actually be welcome since it appears that an LGA version is out of the question, and would be one way to sway desktop users over to Intel's BGA strategy and have them be open to similar options in future chips, such as Broadwell in 2015.

Tagged: qualcomm, Intel, Bay Trail-T, Bay Trail
Bay Trail is still seasons away but engineering samples are, and this should be no surprise, already in use at least for research and development purposes. Someone, somewhere down the line, decided to run a benchmark which was posted online. AnTuTu, the benchmark utilized, measures a spread of factors including memory, integer performance, floating point performance, 3D performance, and so forth. Unfortunately it does also include some non-CPU/GPU factors in its score, albeit barely, so best take it with a grain of salt.
Image Credit: The Droid Guy
The Silvermont-based chip, clocked at an... actually quite modest 1101 MHz, received a synthetic score of 43416. To put that in comparison: arguably the fastest ARM processor on the market, the Qualcomm's Snapdragon 800, tends to find itself with a score around the 30,000-32,000 range which is about 27-31% slower than Intel. The very popular albeit soon deprecated Nexus 7, powered by the Tegra 3, scores 12726.
Personally, I am getting a little flashback of the Intel vs. AMD battle about 8 years ago. We seem to be close to a Conroe (Core 2 Duo) vs. AMD Athlon 64 FX point between Intel and ARM. Intel eclipsed the AMD Athlon 64
FX-57 (update: I meant FX-62) and kept throwing more money at research than AMD could possibly afford. Unless ARM can severely undercut Bay Trail, Intel could follow past trends and simply bury their competitors with tens of billions in capital investment until their products are so far ahead that consumers default to Intel products.
If history repeats itself, this leaves Qualcomm and others in a difficult position. The solution seems to be either to tread water in a price point that Intel ignores or to collectively dump money into ARM and run the "out-research Intel" treadmill. Remember, this is a company who will dump twice AMD's revenue into their Research and Development year-over-year to keep ahead. Unlike Intel's GPU efforts, which did not seem like a problem that cash could solve alone, they know how to make processors.
I would not make business decisions under the assumption x86 will keep Intel hobbled indefinitely.

Tagged: Richland, APU, amd
Accidents happen. AMD has been rolling out their Richland APUs for the last month and partners have been keeping up with supporting products. While common, the problem with rolling releases is the potential confusion over what has and what has not been released. Unfortunately for MSI, their support chart for FM2 CPUs includes a couple of products which are news to us.
AMD will be able to hit the 45W TDP with the, apparently, upcoming A8-6500T and A10-6700T APUs. Tom's Hardware seemed to have slightly different information, their chart does not exactly jive with the one posted by MSI; for instance, they claimed the T suffix implied a low power variant when MSI's chart confirmed a 45W TDP... fairly loud and clear. As such, our table will be my best attempt at combining both charts along with a bit more leaked GPU information from TechPowerUP.
|Base Clock||2.1 GHz||2.5 GHz|
|L2 Cache||4 MB||4 MB|
|L3 Cache||0 MB (N/A)||0 MB (N/A)|
Radeon HD 8550D
(Not HD 8650D)

|GPU Clock||720 MHz||720 MHz|
|GPU Boost Clock||844 MHz (???)||844 MHz (???)|
|GPU Shader Count||256||384|
It is impossible to know expected price, release window, or even whether the product still exists. For that, we will need to wait for an official unveiling... or at least another unofficial one.

The National Supercomputer Center in Guangzho, China, will host the the world's fastest supercomputer by the end of the year. The Tianhe-2, English: "Milky Way-2", is capable of nearly double the floating-point performance of Titan albeit with slightly less performance per watt. The Tianhe-2 was developed by China's National University of Defense Technology.

Comparing new fastest computer with the former, China's Milky Way-2 is able to achieve 33.8627 PetaFLOPs of calculations from 17.808 MW of electricity. The Titan, on the other hand, is able to crunch 17.590 PetaFLOPs with a draw of just 8.209 MW. As such, the new Milky Way-2 uses 12.7% more power per FLOP than Titan.
Titan is famously based on the Kepler GPU architecture from NVIDIA, coupled with several 16-core AMD Opteron server processors clocked at 2.2 GHz. This concept of using accelerated hardware carried over into the design of Tianhe-2, which is based around Intel's Xeon Phi coprocessor. If you include the simplified co-processor cores of the Xeon Phi, the new champion is the sum of 3.12 million x86 cores and 1024 terabytes of memory.
... but will it run Crysis?
... if someone gets around to emulating DirectX in software, it very well could.

Tagged: Intel, haswell, cpu, Broadwell, 14nm
Alongside the good news of 8-core Haswell-E parts, VR-Zone revealed an updated Intel road map that makes no mention of the 14nm Haswell architecture die shrink Broadwell. Broadwell was originally intended to be the next "tick" in Intel's yearly "tick-tock" chip release schedule set to release next year. If recent reports are true, this will no longer be the case. Instead, 2014 will be dominated (at least on the Intel side of things) by consumer Haswell and enthusiast-grade Haswell-E chips.
What is going on with Broadwell?
Broadwell is essentially supposed to be a CPU using the Haswell micro-architecture that is built on a (impressively) smaller 14nm manufacturing process. There may be a few minor tweaks to the architecture or updates to the instruction set extensions, but the big difference between Broadwell and Haswell is the die shrink from 22nm to 14nm. The die shrink will allow for better low-power performance and will be beneficial in battery-powered mobile devices first and foremost. Likely as a result of the main benefits being mobile parts, Intel has previously announced that Broadwell chips would be BGA only, which means that there would not be a traditional LGA socket-ed desktop part. Broadwell chips would only come soldered onto motherboards in bare-bones systems, laptops, and tablets for example.
Despite the small architectural differences, the die shrink alone is a monumental task. Intel needs to not only be able to shrink Haswell and its wealth of transistors to 14nm, but it has to do so in a way that allows them to get the yields and power efficiency characteristics that they want. This is extremely hard, and the move to manufacturing nodes below 22nm is going to get exceedingly difficult. Intel accomplished 22nm with its Tri-gate 3D transistors, but with 14nm they are going to have to push beyond that, and even with its huge money vault, physics is working against them in a big way here. As a result of the huge challenges of moving to 14nm, it seems at this point that Broadwell will not be ready in time for a 2014 launch after all. Instead, Intel is now shooting for a 2015 launch of the BGA Broadwell chips alongside the LGA (socket-ed) 14nm Sky Lake processors (the "tock" to Broadwell's "tick").
Some enthusiasts and media have painted the Broadwell delay to be, at least in part, due to less competition from AMD. That is possible, but I can't help but thinking that slowing down Broadwell is the last thing Intel would want to do. The sooner Intel is able to move its Haswell (and future) micro-architecture-based chips to 14nm and beyond, the sooner AMD is put all that much farther behind. If Intel had managed 14nm Broadwell in 2014, AMD would have been screwed out of a lot of SFF NUC-type systems as well as mobile devices as they would not really be able to compete on performance or power efficiency! (Then Intel could happily focus on trying to bring down ARM in the mobile space, which it seems to want to do heh.) In some internal discussion with PC Perspective's Josh Walrath, I think that Intel would have loved to bring 14nm chips next year but, because of manufacturing process woes, the chips are simply not ready.
The new plan: Refresh Haswell in 2014 with a new Z97 chipset
Now, with the launch of Broadwell moved back to at least 2015, consumers will now be presented with a refresh of 22nm Haswell chips on the consumer side around Q2 2014 and the upcoming launch of enthusiast-platform Haswell-E processors in the second half of 2014.
The Haswell (LGA 1150) refresh will include better binned chips with a lineup that is likely to see a slight speed bump in stock clockspeed across the board as well as an updated Z97 chipset. The new chipset will support 1000 MB/s SATA Express and boot-level malware protection technology in the form of Intel Device Protection and Boot Guard. Granted motherboards using the updated Z97 chipset are not going to be all that alluring to those users already running Z87 chipsets with their Haswell processors. However, users that have not yet upgraded might as well go with the newer chipset and enjoy the small tweaks and benefits that go along with it. In other words, if you were holding out waiting to upgrade to a Broadwell CPU plus motherboard combo, you are going to be waiting at least another year. You will be able to grab a refreshed Haswell CPU and a Z87 or Z97 chipset-based motherboard next year though (which should still be a healthy upgrade if you have a pre-Sandy Bridge system).
Also worth noting is that if you have already upgraded to Haswell, you can rest easy knowing that you have at least another year of your chip being the newest model--quite a feat considering how fast the tech world traditionally moves!
On the other hand, if Haswell just isn't fast enough, there is always Haswell-E to look forward to in 2014! Haswell-E will bring 8-core, 16-thread chips with 20MB of L3 cache (up to ~140W TDP) and the X99 chipset, which should keep the top-end enthusiast market happy no matter the state of Broadwell.
I'm looking forward to more details regarding the 14nm manufacturing process, and hoping that once the chips are on the way the company will be willing to talk about some of the challenges and issues they faced moving to such a small process node (perhaps at IDF? One can hope.) In the mean time, Haswell has another year to shine and make Intel money while AMD works on its HSA and APU strategies.
What do you think about the 14nm Broadwell delay? Does it impact you, or were you waiting for Haswell-E anyway?

Thankfully, they were not "firing" on all four cylinders; while Ryan does prefer thermite, overclockers tend to prefer liquid nitrogen. There are some distinct advantages of ice over fire, the main one for computer users is the potential for massive bumps in frequency and voltage. Of course, you cannot really get any effective use out of a machine that relies on a steady stream of fluid cold enough that it takes less digits to write out its temperature in Kelvin, but a large bump makes good bragging rights.
Finnish overclocker, "The Stilt", managed to push his four-core part to 8000.39 MHz just long enough to have CPU-Z validate his accomplishment. With a frequency multiplier of 63.0 atop a bus speed of 126.99, this gets within 800MHz of the AMD FX-8350 running on just one module (6 of 8 cores disabled) recorded by ASUS late last year.
But no, it will probably not run Crysis.

Ryan reviewed the Core i7 4770K earlier in the month and found it an impressive product. He was not able to properly test the CPU paired with a discrete GPU because of time restraints; we value results measured from direct monitor output, which takes longer than FRAPS and other software results. Still, Ryan believes that the boost in raw CPU performance justifies its existence in desktops without a funky "-E" tagged along for good luck.
For a second opinion, you could check NitroWare to see what a cynical Aussie thinks of Intel's latest offering. Of note, they compare software-measured frame rates between the on-chip GPU and those measured from a GTX 460 on Sandy Bridge, Ivy Bridge, and Haswell. He is nothing if not thorough, collecting his findings over 20 pages.
Ultimately he finds that if you are running Ivy Bridge, you will not benefit too much from the upgrade; Sandy Bridge users and earlier, on the other hand, might want to consider this platform... unless they are wanting to jump into the enthusiast-slot offerings coming up late this year and Haswell-E late the following year.
Also be sure to check back when we have our frametime measurements complete!

Tagged: Intel, Ivy Bridge-E, Haswell-E
In my analysis of the recent Intel Computex keynote, I noted that the displayed confidence came across more as repressing self-doubt. It did not seem, to me, like Intel wants to abandon the high-end enthusiast but rather catch up with their low performance and high efficiency competitors; they just know they are secure in that market. Of course, we could see mid-range choices dwindle and prices stagnate, but I cast doubt that Intel wants to exit the enthusiast market despite their silence about Ivy Bridge-E.
All Images, Credit: VR-Zone
And Intel, now, wants to return some confidence to their high-end consumers comma they are not slowing down exclamation point exclamation point.
VR-Zone, the site which published Ivy Bridge-E's lazy release roadmap, are also the ones to suggest Haswell-E will come before mainstream Broadwell offerings. Once again, all is right with the world. Slated for release around holiday 2014, just a year after Ivy Bridge-E, Haswell-E will come alongside the X99 chipset. Instead of Broadwell, the back to school window of 2014 will by filled by a refresh of 22nm Haswell products with a new 9-series chipset.
Seriously, it's like watching the face of Intel's Tick-Tock while a repairman is tweaking the gears.
In terms of specifications, Haswell-E will come in 8 and 6-core offerings with up to 20MB of cache. Apart from the inclusion of DDR4 support, the main advantage of Haswell-E over the upcoming Ivy Bridge-E is supposed to be raw performance; VR-Zone estimates up to 33-50% better computational strength. A depressingly novel area of improvement as of recent...
Lastly, with recent discussion of the awkwardly hobbled K-series parts, our readers might be happy to know that all Haswell-E parts will be unlocked to overclocking. This, again, leads me to believe that Intel is not hoping to suffocate the enthusiast market but rather sort their users: mid-range consumers will take what they are given and, if they object, send them on the bus to Funk-E town.
Note, while the headlining slide definitively says "All Processors Unlocked"...
... this slide says "For K and Extreme series products." I will assume the latter is out of date?
Which begs the question: what does our readers think about that potential strategy? It could lead to mainstream performance products being pushed down into BGA-territory, but cements the existence of an enthusiast platform.
Intel Prevents Overclocking of non-K Haswell Processors, and Strips Virtualization and TSX Features From K Parts
Subject: Processors | June 13, 2013 - 09:59 AM | Tim Verry
Tagged: tsx, overclocking, Intel, i7-4770k, haswell
First revealed at IDF Beijing, Intel's latest generation 4th Generation Core "Haswell" processors enjoy a refined architecture, improved processor graphics, an integrated voltage regulator (FIVR), and for the enthusiast crowd, new methods for overclocking.
In truth, the methods for overclocking Haswell are very similar to those used to overclock Intel's Sandy Bridge and Ivy Bridge processors. However, Intel has further unlocked the new Haswell CPUs. Enthusiasts can set an overclocked Turbo clockspeed, use additional base clock (BCLK) values (100 MHz, 125 MHz, and 167 MHz), and overclock the unlocked processor graphics core clockspeed and memory clockspeed (memory in 200 MHz or 266 MHz steps). The additional BCLK values allow for easy overclocks without putting the other subsystems (such as the PCI-E bus, GPU, and memory) out of spec, which is important for the PCI-E bus which needs to be close to 100 MHz for a stable system.
The following PC Perspective articles have further information on overclocking unlocked "K" edition Haswell processors:
- Integrated Voltage Regulator and Overclocking Haswell - Ryan pushes a Core i7-4770K to 4.6GHz
- Intel Talks Haswell Overclocking at IDF Beijing - Intel outlines overclocking features of Haswell at IDF
Although Intel's overclocking reveal at IDF was fairly detailed, the company did not get into specifics on how overclocking would work on non-K chips.
On that note, the crew over at the Tech Report uncovered some rather disheartening facts such that the non-K edition Haswell processors will, essentially, be locked at stock speeds and not overclockable (they are slightly more locked down than previous generations).
While the K edition Haswell processors, such as the Core i7-4770K, will enjoy unlocked multipliers, unlocked GPU and memory clockspeeds, and additional BCLK options, the standard non-K chips (ie Core i7-4770, Core i5-4670, et al) will have locked multipliers, no Turbo Boost clockspeed overclocking, and will not be allowed to use the additional 125 MHz and 167 MHz BLCK options, which effectively makes overclocking these standard chips impossible. It may still be possible to push the BLCK up a few MHz, but without the extra
stepping and gearing ratio options, the other component clockspeeds based off that same base clock are going to go out of spec and will become unstable fairly quickly as you try to push that BLCK up.
There is one saving grace for enthusiasts considering a non-K part, however. The standard non-K CPUs will have Intel's latest TSX extensions and enterprise virtualization technologies enabled.
Although quite the head scratcher, Intel has decided to disable TSX, vPro, and VT-d on the unlocked K edition chips. The TSX extensions are not widely used yet, but will provide a noticeable performance boost to future programs that do take advantage of them by allowing developers to essentially mark off sections of code that can be run independently, and thus increase the multi-threaded-ness of the application by running as much code in parallel across multiple cores as possible. Further, the vPro and VT-d features are used by virtual machine applications (with VT-d being more relevant to the consumer side of things).
In short, Intel has continued to lock down and artificially limit its chips, as many enthusiasts suspected would happen. Standard non-K Haswell processors are more locked down than ever, and even the premium unlocked K CPUs suffer with the (odd) removal of TSX and virtualization support. As Mr. Gasior points out, enthusiasts are going to be faced with an odd choice where they can either spend extra money on a premium K part that will overclock but is limited in other ways, or go with the lower cost part that has all of the ISA extensions and virtualization support turned on... but is not overclockable.
In my opinion, locking down the standard chips is one thing-- Intel needs to incentivize enthusiasts to go with the more expensive (~$25 premium) unlocked K processors some how -- but if those same enthusiasts are spending extra money for a premium chip, they should get all the features the accompanying non-K SKU has as well as overclocking.
What do you think about the artificial limitations placed on the various Haswell SKUs?

The Electronic Entertainment Expo (E3) is the biggest event of the year for millions of gamers. The majority of coverage ends up gawking over the latest news out of Microsoft, Sony, or Nintendo, and we certainly will provide our insights in those places if we believe they have been insufficiently explained, but E3 is also a big time for PC gamers too.
5 GHz and unlocked to go from there.
AMD, specifically, has a lot to say this year. In the year of the next-gen console reveals, AMD provides the CPU architecture for two of the three devices and have also designed each of the three GPUs. This just leaves a slight win for IBM, who is responsible for the WiiU main processor, for whatever that is worth. Unless the Steam Box comes to light and without ties to AMD, it is about as close to a clean sweep as any hardware manufacturer could get.
But for the PCs among us...
For those who have seen the EA press conference, you have probably seen lots of sports. If you stuck around after the sports, you probably saw Battlefield 4 being played by 64 players on stage. AMD has been pushing, very strongly, for developer relations over the last year. DICE, formerly known for being an NVIDIA-friendly developer, did not exhibit Battlefield 4 "The Way It's Meant to be Played" at the EA conference. According to one of AMD's Twitter accounts:

On the topic of "Gaming Evolved" titles, AMD is partnering with Square Enix to optimize Thief for GCN and A-Series APUs. The Press Release specifically mentioned Eyefinity and Crossfire support along with a DirectX 11 rendering engine; of course, the enhancements with real, interesting effects are the seemingly boring ones they do not mention.
The last major point from their E3 event was the launch of their 5 GHz FX processors. For more information on that part, check out Josh's thoughts from a couple of days ago.

We have all heard the rumors, but it appears to be true. We had originally heard about a “Centurion” product which would be for extreme overclockers on the AMD side, running at 5 GHz with a 220 watt TDP. Now we finally get to see what all the fuss is about. AMD is releasing two new Vishera based processors that, for the time being, will be limited to system integrators and will be available later this summer.
The top end product is the FX-9590 which has a top turbo speed of 5 GHz. This will be a full four module implementation with the 8 MB of L3 cache. AMD did not give any other details for this particular part. We do not know what the base clock is, we do not know what the TDP is, and we can only assume that the northbridge/L3 cache will be clocked at the standard 2.2 GHz that we have seen on previous Vishera parts.
The second product is the FX-9370 which is again a four module part that has a top turbo speed of 4.7 GHz. Remember that the four modules each have two “cores”, so it is still considered an eight core part. These processors are unlocked, so they can be further overclocked if one so desires. TDP and other details were again skipped for this particular part.
These parts will be going to system integrators first, and I am not entirely sure that AMD will sell them on the market direct to consumers. If AMD does in fact sell to consumers (not implied at all in the press release) then they likely will have to bundle it with a very robust cooler. Probably something along the lines of what we saw with the original FX-8150 LCS bundle.
Consider that the FX-8350 is a 4 GHz base clock product with a max turbo of 4.2 GHz and having a TDP of 125 watts, we probably have to assume that the 220 watt number bandied about is accurate. A pretty beefy air cooler would be required, or the aforementioned liquid cooling system. AMD also likely had GLOBALFOUNDRIES change the “mix” when fabricating these parts. These batches probably feature more leaky transistors that can achieve higher speeds without an extreme amount of voltage.
This is an interesting move by AMD. Remember those TWKR chips that they released that were designed for LN2 use? There were a very limited number of those units, and we can imagine that while the FX-9000 series will be in greater numbers they still will not be commonplace on the retail market. SI’s like Maingear will be introducing systems this summer featuring these chips. Performance will be good with these solutions, but the tradeoff is of course power consumption and heat production as compared to similarly performing (and stock clocked) Intel i7 3770K and 4770K parts.
AMD is doing their best to address the enthusiast market, but until Kaveri hits the streets we will not see any major upgrades beyond these parts.
We received some further info about this chip. The TDP is up in the 220 watt region. It utilizes Turbo Core 3.0 to help achieve those speeds, so it seems that some of the work that went into Richland has made it into these latest FX processors. BIOS updates are probably a must. These chips will only be going to system integrators (SIs) and will be bundled with a liquid cooling system. We have no idea what the price will be since these will only be sold to SIs. Systems should be available after July 16.

Odd, turns out I found two brand new AMD A10-6800K Richland APUs sitting on my desk this morning. I called AMD to ask what this was all about and they said that if I didn't need them, I might as well give them away to our readers.
"Oh, and throw in a free copy of the new SimCity while you're at it," they told me.
Who am I to argue?
So let's have a giveaway!
We are handing out two AMD A10-6800K "Richland" APUs for you to build a brand new PC around and including a key for SimCity with each of them. If you haven't read Josh's review of the A10-6800K APU you should definitely do so; it will help educate you on exactly what you are getting - for FREE.
To enter, I need you to leave a comment on this very news post below telling us what you would build with a brand new A10 APU - you don't have to be registered to do so but we'd sure like it if you were. (Make sure you leave your correct email address so I can get in touch with you if you win.) Also, feel free to stop by the PC Perspective YouTube channel and either give our videos a gander or subscribe. I think we put out some great content there and we'd like more of you to see it.
I will pick one winner on June 17th and another on June 24th so you have two separate weeks to potentially win!
A big thanks goes out to AMD for supplying the APUs and copies of SimCity for this giveaway. Good luck!!

Intel had a host of new technologies to show off at Computex this year, starting of course with the Haswell processor launch. Hopefully you have read our review of the Core i7-4770K LGA1150 CPU already but thanks to some video sent our way, we have other interesting bits to share.
Below you will see Intel demonstrating four new products. First is the Acer Aspire S7 using a Haswell dual-core platform playing back 4K content. Next up is an Ivy Bridge tablet that is running completely fanless (passive) thus generating no noise at all while still offering impressive CPU and graphics performance. Intel then pulls a Lenovo K900 Android smartphone out of its pocket powered by the Clovertrail+ enabled Atom Z2580 SoC. Finally, we get a sneak peak at the next-generation of SoC designs with a look at a Silvermont-based Baytrail tablet running at 2560x1440.

Richland is here, in the form of the A10-6800K with a 4.1GHz base clock and 4.4GHz Turbo clock, support for DDR3-2133 and an improved GPU called the 8670D with 384 shaders and a 844MHz clock speed ... all for $142! Computationally you can compare it to a Core i3 or a slower Core i5 but graphically this CPU is head and shoulders above the competition as you can see in X-Bit Labs' testing. You really need to keep the price in mind, as it may not provide as much power as a Core-i5 it costs about half as much which can mean a lot to someone on a tight budget, especially when they can skip purchasing a discrete GPU altogether.
Make sure to check out Josh's reivew where he contrasts the last few generations of AMD chips.
"AMD decided to refresh their Socket FM2 platform and release a new generation of hybrid processors for it based on Richland design. This is exactly the one that earned the “Elite Performance APU Platform” title in the mobile segment."
