OpenCL Support in a Meaningful Way
Adobe had OpenCL support since last year. You would never benefit from its inclusion unless you ran one of two AMD mobility chips under Mac OSX Lion, but it was there. Creative Cloud, predictably, furthers this trend with additional GPGPU support for applications like Photoshop and Premiere Pro.
This leads to some interesting points:
- How OpenCL is changing the landscape between Intel and AMD
- What GPU support is curiously absent from Adobe CC for one reason or another
- Which GPUs are supported despite not... existing, officially.
This should be very big news for our readers who do production work whether professional or for a hobby. If not, how about a little information about certain GPUs that are designed to compete with the GeForce 700-series?

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!

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.

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

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:
— AMD Radeon Graphics (@AMDRadeon) June 12, 2013
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.

Tagged: vishera, TWKR, piledriver, FX-9590, FX-9370, Centurion, amd
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."

JJ pays PC Perspective a visit!
In case you hadn't heard, on June the 4th, (world famous) JJ Guerrero from ASUS stopped by the PC Perspective offices to help host a live stream focused on Z87 platforms and the Intel Haswell processor. Since Intel decided to launch on a Saturday morning, you might have missed the boat: the Core i7-4770K was reviewed right here on PC Perspective and the results are pretty good.
Motherboards, we got motherboards here!!
Along with Haswell though is the release of the new Z87 chipset and with THAT, about 100 different ASUS motherboards. I exaggerate, but only a little. In our live stream that aired for about 4.5 hours, JJ and I discussed about 20 different motherboard ranging from Mini-ITX options to the budget-minded Z87-A and even the ROG Maximus VI Extreme!
Below you will find an on-demand version of the stream, broken up into five segments.
ASUS Z87 Motherboard Segmentation
This first segment details the mindset ASUS had when creating the four different motherboard product lines: Mainstream, Workstation, TUF and ROG. Why do they need all of these options and what features and quality points are common across the entire families?
ASUS Mainstream Z87 Motherboard Lineup
ASUS' new mainstream line of motherboards with the z87 chipset range from the Z87-A to the Z87-Deluxe/Dual. JJ talks about the features that are added as you move up the product stack so that you can find the option that fits your platform needs and budget.
