According to VR-Zone, AMD has reworked their business, last Thursday, sorting each of their projects into two divisions and moving some executives around. The company is now segmented into the "Enterprise, Embedded, and Semi-Custom Business Group", and the "Computing and Graphics Business Group". The company used to be divided between "Computing Solutions", which handled CPUs, APUs, chipsets, and so forth, "Graphics and Visual Solutions", which is best known for GPUs but also contains console royalties, and "All Other", which was... everything else.

Lisa Su, former general manger of global business, has moved up to Chief Operating Officer (COO), along with other changes.

This restructure makes sense for a couple of reasons. First, it pairs some unprofitable ventures with other, highly profitable ones. AMD's graphics division has been steadily adding profitability to the company while its CPU division has been mostly losing money. Secondly, "All Other" is about a nebulous as a name can get. Instead of having three unbalanced divisions, one of which makes no sense to someone glancing at AMD's quarterly earnings reports, they should now have two, roughly equal segments.

At the very least, it should look better to an uninformed investor. Someone who does not know the company might look at the sheet and assume that, if AMD divested from everything except graphics, that the company would be profitable. If, you know, they did not know that console contracts came into their graphics division because their compute division had x86 APUs, and so forth. This setup is now more aligned to customers, not products.

A refresh for Haswell

Intel is not very good at keeping secrets recently. Rumors of a refreshed Haswell line of processors have been circulating for most of 2014.  In March, it not only confirmed that release but promised an even more exciting part called Devil's Canyon. The DC parts are still quad-core Haswell processors built on Intel's 22nm process technology, but change a few specific things. 

Intel spent some time on the Devil's Canyon Haswell processors to improve the packaging and thermals for overclockers and enthusiasts. The thermal interface material (TIM) that lies in between the die and the heat spreader has been updated to a next-generation polymer TIM (NGPTIM). The change should improve cooling performance of all currently shipping cooling solutions (air or liquid), but it is still a question just HOW MUCH this change will actually matter.

You can also tell from the photo comparison above that Intel has added capacitors to the back of the processor to "smooth" power delivery. This, in combination with the NGPTIM, should enable a bit more headroom for clock speeds with the Core i7-4790K.

slides08.jpg

In fact, there are two Devil's Canyon processors being launched this month. The Core i7-4790K will sell for $339, the same price as the Core i7-4770K, while the Core i5-4690K will sell for $242. The lower end option is a 3.5 GHz base clock, 3.9 GHz Turbo clock quad-core CPU without HyperThreading. While a nice step over the Core i5-4670K, it's only 100 MHz faster. Clearly the Core i7-4790K is the part everyone is going to be scrambling to buy.

Another interesting change is that both the Core i7-4790K and the Core i5-4690K enable support for both Intel's VT-d virtualization IO technology and Intel's TSX-NI transactional memory instructions. This makes them the first enthusiast-grade unlocked processors from Intel to support them!

As Intel states it, the Core i7-4790K and the Core i5-4690K have been "designed to be used in conjunction with the Z97 chipset." That being said, at least one motherboard manufacturer, ASUS, has released limited firmware updates to support the Devil's Canyon parts on Z87 products. Not all motherboards are going to be capable, and not all vendors are going to the spend the time to integrate support, so keep an eye on the support page for your specific motherboard.

The CPU itself looks no different on the top, save for the updated model numbering.

Core i7-4790K on the left, Core i7-4770K on the right

On the back you can see the added capacitors that help with stable overclocking.

The clock speed advantage that the Core i7-4790K provides over the Core i7-4770K should not be overlooked, even before overclocking is taken into consideration. A 500 MHz base clock boost is 14% higher in this case and in those specific CPU-limited tasks, you should see very high scaling.

Thinking of swapping Linux for Windows on your new Bay Trail NUC?

It would seem that installing Linux on your brand new Bay Trail powered NUC will cost you a bit of performance.  The testing Phoronix has performed on Intel NUC DN2820FYKH proves that it can handle running Linux without a hitch, however you will find that your overall graphical performance will dip a bit.  Using MESA 10.3 and both the current 3.13 kernel and the 3.15 development kernel Phoronix saw a small delta in performance between Ubuntu 14.04 and Win 8.1 ... until they hit the OpenGL performance.  As there is still no full OpenGL 4.0+ support there were tests that could not be run and even with the tests that could be there was a very large performance gap.  Do not let this worry you, as they point out in the article there is a dedicated team working on full compliance and you can expect updated results in the near future.

"A few days ago my benchmarking revealed Windows 8.1 is outperforming Ubuntu Linux with the latest Intel open-source graphics drivers on Haswell hardware. I have since conducted tests on the Celeron N2820 NUC, and sadly, the better OpenGL performance is found with Microsoft's operating system."

Subject: Processors, Mobile | June 4, 2014 - 11:00 AM |
Tagged: computex, computex 2014, arm, cavium, thunderx

While much of the news coming from Computex was centered around PC hardware, many of ARMs partners are making waves as well. Take Cavium for example, introducing the ThunderX CN88XX family of processors. With a completely custom ARMv8 architectural core design, the ThunderX processors will range from 24 to 48 cores and are targeted at large volume servers and cloud infrastructure. 48 cores!

The ThunderX family will be the first SoC to scale up to 48 cores and with a clock speed of 2.5 GHz and 16MB of L2 cache, should offer some truly impressive performance levels. Cavium claims to be the first socket-coherent ARM processor as well, using the Cavium Coherent Processor Interconnect. The I/O capacity stretches into the hundreds of Gigabits and quad channel DDR3 and DDR4 memory speeds up to 2.4 GHz keep the processors fed with work.

Here is the breakdown on the ThunderX families.

ThunderX_CP: Up to 48 highly efficient cores along with integrated virtSOC, dual socket coherency, multiple 10/40 GbE and high memory bandwidth. This family is optimized for private and public cloud web servers, content delivery, web caching, search and social media workloads.

ThunderX_ST: Up to 48 highly efficient cores along with integrated virtSOC, multiple SATAv3 controllers, 10/40 GbE & PCIe Gen3 ports, high memory bandwidth, dual socket coherency, and scalable fabric for east-west as well as north-south traffic connectivity. This family includes hardware accelerators for data protection/ integrity/security, user to user efficient data movement (RoCE) and compressed storage. This family is optimized for Hadoop, block & object storage, distributed file storage and hot/warm/cold storage type workloads.

ThunderX_SC: Up to 48 highly efficient cores along with integrated virtSOC, 10/40 GbE connectivity, multiple PCIe Gen3 ports, high memory bandwidth, dual socket coherency, and scalable fabric for east-west as well as north-south traffic connectivity. The hardware accelerators include Cavium’s industry leading, 4th generation NITROX and TurboDPI technology with acceleration for IPSec, SSL, Anti-virus, Anti-malware, firewall and DPI. This family is optimized for Secure Web front-end, security appliances and Cloud RAN type workloads.

ThunderX_NT: Up to 48 highly efficient cores along with integrated virtSOC, 10/40/100 GbE connectivity, multiple PCIe Gen3 ports, high memory bandwidth, dual socket coherency, and scalable fabric with feature rich capabilities for bandwidth provisioning , QoS, traffic Shaping and tunnel termination. The hardware accelerators include high packet throughput processing, network virtualization and data monitoring. This family is optimized for media servers, scale-out embedded applications and NFV type workloads.

We spoke with ARM earlier this year about its push into the server market and it is partnerships like these that will begin the ramp up to wide spread adoption of ARM-based server infrastructure. The ThunderX family will begin sampling in early Q4 2014 and production should be available by early 2015.

Kaveri Goes Mobile

The processor market is in an interesting place today. At the high end of the market Intel continues to stand pretty much unchallenged, ranging from the Ivy Bridge-E at $1000 to the $300 Haswell parts available for DIY users. The same could really be said for the mobile market - if you want a high performance part the default choice continues to rest with Intel. But AMD has some interesting options that Intel can't match when you start to enter the world of the mainstream notebook. The APU was slow to develop but it has placed AMD in a unique position, separated from the Intel processors with a more or less reversed compute focus. While Intel dominates in the performance on the x86 side of things, the GPU in AMD's latest APUs continue to lead in gaming and compute performance.

The biggest problem for AMD is that the computing software ecosystem still has not caught up with the performance that a GPU can provide. With the exception of games, the GPU in a notebook or desktop remains under utilized. Certain software vendors are making strides - see the changes in video transcoding and image manipulation - but there is still some ground AMD needs to accelerate down.

slides01.jpg

Today we are looking at the mobile version of Kaveri, AMD's latest entry into the world of APUs. This processor combines the latest AMD processor architecture with a GCN-based graphics design for a pretty advanced part. When the desktop version of this processor was released, we wrote quite a bit about the architecture and the technological advancements made into, including becoming the first processor that is fully HSA compliant. I won't be diving into the architecture details here since we covered them so completely back in January just after CES.

slides02.jpg

The mobile version of Kaveri is basically identical in architecture with some changes for better power efficiency. The flagship part will ship with 12 Compute Cores (4 Steamroller x86 cores and 8 GCN cores) and will support all the same features of GCN graphics designs including the new Mantle API.

slides03.jpg

Early in the spring we heard rumors that the AMD FX brand was going to make a comeback! Immediately enthusiasts were thinking up ways AMD could compete against the desktop Core i7 parts from Intel; could it be with 12 cores? DDR4 integration?? As it turns out...not so much.

Tagged: Intel, amd, richard huddy

Interesting news is crossing the ocean today as we learn that Richard Huddy, who has previously had stints at NVIDIA, ATI, AMD and most recently, Intel, is teaming up with AMD once again. Richard brings with him years of experience and innovation in the world of developer relations and graphics technology. Often called "the Godfather" of DirectX, AMD wants to prove to the community it is taking PC gaming seriously.

richardhuddy.jpg

The official statement from AMD follows:

AMD is proud to announce the return of the well-respected authority in gaming, Richard Huddy. After three years away from AMD, Richard returns as AMD's Gaming Scientist in the Office of the CTO - he'll be serving as a senior advisor to key technology executives, like Mark Papermaster, Raja Koduri and Joe Macri. AMD is extremely excited to have such an industry visionary back. Having spent his professional career with companies like NVIDIA, Intel and ATI, and having led the worldwide ISV engineering team for over six years at AMD, Mr. Huddy has a truly unique perspective on the PC and Gaming industries.

Mr. Huddy rejoins AMD after a brief stint at Intel, where he had a major impact on their graphics roadmap.  During his career Richard has made enormous contributions to the industry, including the development of DirectX and a wide range of visual effects technologies.  Mr. Huddy’s contributions in gaming have been so significant that he was immortalized as ‘The Scientist’ in Max Payne (if you’re a gamer, you’ll see the resemblance immediately). 

Kitguru has a video from Richard Huddy explaining his reasoning for the move back to AMD.

This move points AMD in a very interesting direction going forward. The creation of the Mantle API and the debate around AMD's developer relations programs are going to be hot topics as we move into the summer and I am curious how quickly Huddy thinks he can have an impact.

I have it on good authority we will find out very soon.

Computex 2014: Intel Officially Releases Devil's Canyon, Core i7-4790K

Back in March, we learned from Intel that they were planning to release a new Haswell refresh processor targeted at the overclocking and gaming market, code named Devil's Canyon. As we noted then, this new version of the existing processors will include new CPU packaging and the oft-requested improved thermal interface material (TIM). What wasn't known were the final clock speeds and availability time lines.

slides01.jpg

The new Core i7-4790K processor will ship with a 4.0 GHz base clock with a maximum Turbo clock rate of 4.4 GHz! That is a 500 MHz increase in base clock speed over the Core i7-4770K and should result in a substantial (~10-15%) performance increase. The processor still supports HyperThreading for a total of 8 threads and is fully unlocked for even more clock speed improvements.

slides04.jpg

All of the other specifications remain the same - HD Graphics 4600, 8MB of L3 cache, 16 lanes of PCI Express, etc.

slides13.jpg

Intel spent some time on the Devil's Canyon Haswell processors to improve the packaging and thermals for overclockers and enthusiasts. The thermal interface material (TIM) that is between the top of the die and the heat spreader has been updated to a next-generation polymer TIM (NGPTIM). The change should improve cooling performance of all currently shipping cooling solutions (air or liquid) but it is still a question just HOW MUCH this change will actually matter. 

You can also tell from the photo comparison above that Intel has added capacitors to the back of the processor to "smooth" power delivery. This, combined with the NGPTIM should enable a bit more headroom for clock speeds with the Core i7-4790K.

slides08.jpg

In fact, there are two Devil's Canyon processors being launched this month. The Core i7-4790K will sell for $339, the same price as the Core i7-4770K, while the Core i5-4690K will sell for $242. The lower end option is a 3.5 GHz base clock, 3.9 GHz Turbo clock quad-core CPU without HyperThreading. While a nice step over the Core i5-4670K, it's only 100 MHz faster. Clearly the Core i7-4790K is the part everyone is going to be scrambling to buy.

slides07.jpg

Not to be left out, Intel is offering an unlocked Pentium processor for users on a tighter budget. This dual core CPU runs at 3.2 GHz base frequency and includes not just HD Graphics but support for QuickSync video. 

slides09.jpg

At just $72, the Pentium G3258 will likely be a great choice for gamers that lean towards builds like the one we made for the Titanfall release.

I was hoping to have a processor in hand to run benchmarks and overclocking testing on, but they haven't quite made it to the office yet. The 4.0 GHz clock speed is easily emulated by any 4770K and some BIOS tweaks but the additional overclocking headroom provided by the changed thermal interface is still in question. Honestly, based on conversations with motherboard vendors, Devil's Canyon headroom is only 100-200 MHz over the base Haswell parts, so don't expect to reach 6.0 GHz all of the sudden.

Later in the week we'll have the Core i7-4790K in hand and you can expect a full review shortly thereafter.

Intel Announces Partnership with Rockchip to Produce Low-Cost x86 Atom SoC

Tagged: tablet, SoC, Rockchip, mobile, Intel, atom, arm, Android

While details about upcoming Haswell-E processors were reportedly leaking out, an official announcement from Intel was made on Tuesday about another CPU product - and this one isn't a high-end desktop part. The chip giant is partnering with the fabless semiconductor manufacturer Rockchip to create a low-cost SoC for Android devices under the Intel name, reportedly fabricated at TSMC.

rockchip_logo.png

We saw almost exactly the opposite of this arrangement last October, when it was announced that Altera would be using Intel to fab ARMv8 chips. Try to digest this: Instead of Intel agreeing to manufacture another company's chip with ARM's architecture in their fabs, they are going through what is said to be China's #1 tablet SoC manufacturer to produce x86 chips...at TSMC? It's a small - no, a strange world we live in!

From Intel's press release: "Under the terms of the agreement, the two companies will deliver an Intel-branded mobile SoC platform. The quad-core platform will be based on an Intel® Atom™ processor core integrated with Intel's 3G modem technology."

As this upcoming x86 SoC is aimed at entry-level Android tablets this announcement might not seem to be exciting news at first glance, but it fills a short term need for Intel in their quest for market penetration in the ultramobile space dominated by ARM-based SoCs. The likes of Qualcomm, Apple, Samsung, TI, and others (including Rockchip's RK series) currently account for 90% of the market, all using ARM.

As previously noted, this partnership is very interesting from an industry standpoint, as Intel is sharing their Atom IP with Rockchip to make this happen. Though if you think back, the move is isn't unprecedented... I recall something about a little company called Advanced Micro Devices that produced x86 chips for Intel in the past, and everything seemed to work out OK there...

atom.png

When might we expect these new products in the Intel chip lineup codenamed SoFIA? Intel states "the dual-core 3G version (is) expected to ship in the fourth quarter of this year, the quad-core 3G version...expected to ship in the first half of 2015, and the LTE version, also due in the first half of next year." And again, this SoC will only be available in low-cost Android tablets under this partnership (though we might speculate on, say, an x86 SoC powered Surface or Ultrabook in the future?).

Rumor: New Intel Core i7 Haswell-E Processor Specs Allegedly Leaked

Subject: Processors | May 27, 2014 - 06:58 PM |
Tagged: X99, rumors, octocore, lga2011, Intel, Haswell-E, cpu

As with any high-profile release there have been rumors circulating around Intel's upcoming high-end desktop processors for the X99 chipset, and a report today from Chinese site Coolaler claims to have the specs on these new Haswell-E CPU's.

intel_i7-5960x_5930k_5820k_sp.jpg

The alleged Haswell-E lineup

Of particular interest are the core counts, which appear to have been increased compared to the current Ivy Bridge-E products. The lineup will reportedly include a 6-core i7-5820K, 6-core i7-5930K, and 8-core i7-5960X. Yep, not only are we looking at an octo-core desktop part but now even the "entry-level" Extreme part might have 6 cores.

Nothing wrong with more cores (and this will be especially attractive if we see the same MSRP's as Ivy Bridge-E) but there might be one caveat with the i7-5820K, as the reported specs show fewer PCIe lanes on this CPU with 28, compared to the 40 lanes found on the higher Haswell-E parts (and all current Ivy-Bridge-E parts).

Haswell-E would still provide more lanes than the current desktop i7 parts (an i7-4770K has only 16), but the disparity would create an interesting quandary for a potential adopter. Though x8 connections for multi-GPU setups is par for the course already on non-X79 desktop systems, the SATA Express and M.2 standards will put more of a premium on PCIe lane allocation for storage going forward.

inte_core_i7-5690x_cpu-z.png

An alleged CPU-Z screenshot of an 8-core i7-5960X part

Of course no official word from Intel on the matter yet, and only speculation on pricing. This is completely unsubstantiated, but is certainly of interest - particularly as hex-core i7's previously commanded the pricing of a more premium part in each prior iteration.

Reuters: Intel CEO says Broadwell PCs for sale by holidays

Apparently attending Maker Faire gets you more than a look at the latest hacked gadgets produced by the community. Reuters got to talk with Intel CEO Brian Krzanich who confirmed that the company's upcoming Broadwell architecture processors using the new 14nm process technology would be on store shelves in time for the holidays.

"I can guarantee for holiday, and not at the last second of holiday," Krzanich said in an interview. "Back to school - that's a tight one. Back to school you have to really have it on-shelf in July, August. That's going to be tough."

broadwell.jpg

Dissecting that comment we can assume that Broadwell will likely be made available in September or October of this year. This becomes the most precise word from the mouth of Intel about the release of these new parts but of course there wasn't much detail to be had. Though "computers" was mentioned he did not specify notebooks, all-in-ones or desktops. And more importantly for our readers, he did not specify anything about the socketed parts we have been promised would run on the newly released Intel Z97 chipset.
