Rumors recently surfaced via VR-Zone china that AMD’s Kaveri APU successor will be code-named Carrizo, and it will be compatible with the upcoming FM2+ socket and AMD A88X chipset that Kaveri will use. 

AMD’s Carrizo APUs will reportedly be available in TDPs up to 65W and will feature Excavator CPU cores along with a next generation Radeon GPU. Much like Kaveri, Carrizo will be fully HSA compliant. The chips will also include support for DDR4.

Carrizo will allegedly begin sampling in August 2014 with mass production starting around December. That means Carrizo will be available for purchase within the first half of 2015.

FM2+ boards like the ASUS A55BM-A/USB3 are rumored to support AMD's Carrizo APUs (the successor to Kaveri).

The rumors also suggest that Carrizo will be joined by a low power “Beema” System on a Chip (SoC) and a BGA-based Nolan APU for embedded systems. Details on these complementary chips are scarce, however. Perhaps most telling is last bit of the article that suggests that AMD will not be releasing a AM3+ Vishera CPU-only processor successor. It seems AMD is going all in as an APU company after all.

I have been looking forward to the launh of AMD's Kaveri since AFDS 2012, and Carrizo appears to be a refinement of that chip. It should be more power efficient and faster thanks to architecture tweaks and process shrinks. I think that AMDs architecture and HSA approach has potential, and I'm excited to see what these upcoming chips can do with regards to performance.

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
P9X79 Series 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?

AMD A10-6800K APU Overclocked to 8.2GHz

Subject: Processors | July 28, 2013 - 01:08 PM |
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.

AMD A10-6800K Richland APU Overclocked to 8GHz.jpg

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.

Haswell to Reach 4.5W SDP in Limited Quantities

Subject: General Tech, Processors, Mobile | July 23, 2013 - 06:58 PM |
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.

11-intel-green.png

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.

ARM-Mali-T628.jpg

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.

Just how does a 5GHz AMD chip perform?

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."

Engineering Sample of Intel Core i7-4960X, Ivy Bridge-E

Subject: General Tech, Processors | July 18, 2013 - 07:41 PM |
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.

Single Threaded

Multi Threaded

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).
  • Multi-threaded: 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?

Intel Launching New BGA Processors: Three New Bay Trail Chips in Q4 and Three Haswell CPUs in 2014

Subject: Processors | July 12, 2013 - 10:06 PM |
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.

Intel Roadmap Showing New BGA Bay Trail and Haswell Processors.jpg

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.

10W TDP BGA Bay Trail CPUs (ETA: Q4'13)
  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).

65W TDP BGA Haswell CPUs (ETA: 2014)
  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.

Battle of the IGPs

Our long journey with Frame Rating, a new capture-based analysis tool to measure graphics performance of PCs and GPUs, began almost two years ago as a way to properly evaluate the real-world experiences for gamers.  What started as a project attempting to learn about multi-GPU complications has really become a new standard in graphics evaluation and I truly believe it will play a crucial role going forward in GPU and game testing. 

Today we use these Frame Rating methods and tools, which are elaborately detailed in our Frame Rating Dissected article, and apply them to a completely new market: notebooks.  Even though Frame Rating was meant for high performance discrete desktop GPUs, the theory and science behind the entire process is completely applicable to notebook graphics and even on the integrated graphics solutions on Haswell processors and Richland APUs.  It also is able to measure performance of discrete/integrated graphics combos from NVIDIA and AMD in a unique way that has already found some interesting results.

 

Battle of the IGPs

Even though neither side wants us to call it this, we are testing integrated graphics today.  With the release of Intel’s Haswell processor (the Core i7/i5/i3 4000) the company has upgraded the graphics noticeably on several of their mobile and desktop products.  In my first review of the Core i7-4770K, a desktop LGA1150 part, the integrated graphics now known as the HD 4600 were only slightly faster than the graphics of the previous generation Ivy Bridge and Sandy Bridge.  Even though we had all the technical details of the HD 5000 and Iris / Iris Pro graphics options, no desktop parts actually utilize them so we had to wait for some more hardware to show up.

When Apple held a press conference and announced new MacBook Air machines that used Intel’s Haswell architecture, I knew I could count on Ken to go and pick one up for himself.  Of course, before I let him start using it for his own purposes, I made him sit through a few agonizing days of benchmarking and testing in both Windows and Mac OS X environments.  Ken has already posted a review of the MacBook Air 11-in model ‘from a Windows perspective’ and in that we teased that we had done quite a bit more evaluation of the graphics performance to be shown later.  Now is later.

So the first combatant in our integrated graphics showdown with Frame Rating is the 11-in MacBook Air.  A small, but powerful Ultrabook that sports more than 11 hours of battery life (in OS X at least) but also includes the new HD 5000 integrated graphics options.  Along with that battery life though is the GT3 variation of the new Intel processor graphics that doubles the number of compute units as compared to the GT2.  The GT2 is the architecture behind the HD 4600 graphics that sits with nearly all of the desktop processors, and many of the notebook versions, so I am very curious how this comparison is going to stand.

Intel's Bay Trail (-T) can ARM Wrestle. Leaked Benchmarks.

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.

The Droid Guy compiled it with a few scores from competing, ARM, devices.

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.
