UPDATE (August 22nd, 11:11pm ET): I reached out to GlobalFoundries over the weekend for a comment and the company had this to say:
"We would like to confirm that GF is transitioning directly from 14nm to 7nm. We consider 10nm as more a half node in scaling, due to its limited performance adder over 14nm for most applications. For most customers in most of the markets, 7nm appears to be a more favorable financial equation. It offers a much larger economic benefit, as well as performance and power advantages, that in most cases balances the design cost a customer would have to spend to move to the next node.
As you stated in your article, we will be leveraging our presence at SUNY Polytechnic in Albany, the talent and know-how gained from the acquisition of IBM Microelectronics, and the world-class R&D pipeline from the IBM Research Alliance—which last year produced the industry’s first 7nm test chip with working transistors."
An unexpected bit of news popped up today via TPU that alleges GlobalFoundries is not only developing 7nm technology (expected), but that the company will skip production of the 10nm node altogether in favor of jumping straight from the 14nm FinFET technology (which it licensed from Samsung) to 7nm manufacturing based on its own in house design process.
Reportedly, the move to 7nm would offer 60% smaller chips at three times the design cost of 14nm which is to say that this would be both an expensive and impressive endeavor. Aided by Extreme Ultraviolet (EUV) lithography, GlobalFoundries expects to be able to hit 7nm production sometime in 2020 with prototyping and small usage of EUV in the year or so leading up to it. The in house process tech is likely thanks to the research being done at the APPC (Advanced Patterning and Productivity Center) in Albany New York along with the expertise of engineers and design patents and technology (e.g. ASML NXE 3300 and 3300B EUV) purchased from IBM when it acquired IBM Microelectronics. The APPC is reportedly working simultaneously on research and development of manufacturing methods (especially EUV where extremely small wavelengths of ultraviolet light (14nm and smaller) are used to etch patterns into silicon) and supporting production of chips at GlobalFoundries' "Malta" fab in New York.

Intel's Custom Foundry Group will start pumping out ARM chips in early 2017 followed by Intel's own 10nm Cannon Lake processors in 2018 and Samsung will be offering up its own 10nm node as soon as next year. Meanwhile, TSMC has reportedly already tapped out 10nm wafers and will being prodction in late 2016/early 2017 and claims that it will hit 5nm by 2020. With its rivals all expecting production of 10nm chips as soon as Q1 2017, GlobalFoundries will be at a distinct disadvantage for a few years and will have only its 14nm FinFET (from Samsung) and possibly its own 14nm tech to offer until it gets the 7nm production up and running (hopefully!).
Previously, GlobalFoundries has stated that:
“GLOBALFOUNDRIES is committed to an aggressive research roadmap that continually pushes the limits of semiconductor technology. With the recent acquisition of IBM Microelectronics, GLOBALFOUNDRIES has gained direct access to IBM’s continued investment in world-class semiconductor research and has significantly enhanced its ability to develop leading-edge technologies,” said Dr. Gary Patton, CTO and Senior Vice President of R&D at GLOBALFOUNDRIES. “Together with SUNY Poly, the new center will improve our capabilities and position us to advance our process geometries at 7nm and beyond.”
If this news turns out to be correct, this is an interesting move and it is certainly a gamble. However, I think that it is a gamble that GlobalFoundries needs to take to be competitive. I am curious how this will affect AMD though. While I had expected AMD to stick with 14nm for awhile, especially for Zen/CPUs, will this mean that AMD will have to go to TSMC for its future GPUs or will contract limitations (if any? I think they have a minimum amount they need to order from GlobalFoundries) mean that GPUs will remain at 14nm until GlobalFoundries can offer its own 7nm? I would guess that Vega will still be 14nm, but Navi in 2018/2019? I guess we will just have to wait and see!

Gunning for Broadwell-E
As I walked away from the St. Regis in downtown San Francisco tonight, I found myself wandering through the streets towards my hotel with something unique in tow. It was a smile. I was smiling, thinking about what AMD had just demonstrated and showed at its latest Zen processor reveal. The importance of this product launch can literally not be overstated for a company struggling to find a foothold to hang on to in a market that it once had a definitive lead. It’s been many years since I left a conference call, or a meeting, or a press conference feeling genuinely hopefully and enthusiastic about what AMD has shown me. Tonight I had that.
AMD’s CEO Lisa Su, and CTO Mark Papermaster, took stage down the street from the Intel Developer Forum to roll out a handful of new architectural details about the Zen architecture while also showing the first performance results comparing it to competing parts from Intel. The crowd in attendance, a mix of media and analysts, were impressed. The feeling was palpable in the room.
It’s late as I write this, and while there are some interesting architecture details to discuss, I think it is in everyone’s best interest that we touch on them lightly for now, and instead refocus on the deep-dive once the Hot Chips information comes out early next week. What you really want to know is clear: can Zen make Intel work again? Can Zen make that $1700 price tag on the Broadwell-E 6950X seem even more ludicrous? Yes.
The Zen Architecture
Much of what was discussed from the Zen architecture is a re-release of what has been out in recent months. This is a completely new, from the ground up, microarchitecture and not a revamp of the aging Bulldozer design. It integrated SMT (simultaneous multi-threading), a first for an AMD CPU, to better take efficient advantage of a longer pipeline. Intel has had HyperThreading for a long time now and AMD is finally joining the fold. A high bandwidth and low latency caching system is used to “feed the beast” as Papermaster put it and utilizing 14nm process technology (starting at Global Foundries) gives efficiency, and scaling a significant bump while enabling AMD to scale from notebooks to desktops to servers with the same architecture.
By far the most impressive claim from AMD thus far was that of a 40% increase in IPC over previous AMD designs. That’s a HUGE claim and is key to the success or failure of Zen. AMD proved to me today that the claims are real and that we will see the immediate impact of that architecture bump from day one.
Press was told of a handful of high level changes to the new architecture as well. Branch prediction gets a complete overhaul. This marks the first AMD processor to have a micro-op cache. Wider execution width with broader instruction schedulers are integrated, all of which adds up to much higher instruction level parallelism to improve single threaded performance.
Performance improvements aside, throughput and efficiency go up with Zen as well. AMD has integrated an 8MB L3 cache and improved prefetching for up 5x the cache bandwidth available per core on the CPU. SMT makes sure the pipeline stays full to prevent “bubbles” that introduce latency and lower efficiency while region-specific power gating means that we’ll see Zen in notebooks as well as enterprise servers in 2017. It truly is an impressive design from AMD.
Summit Ridge, the enthusiast platform that will be the first product available with Zen, is based on the AM4 platform and processors will go up to 8-cores and 16-threads. DDR4 memory support is included, PCI Express 3.0 and what AMD calls “next-gen” IO – I would expect a quick leap forward for AMD to catch up on things like NVMe and Thunderbolt.
The Real Deal – Zen Performance
As part of today’s reveal, AMD is showing the first true comparison between Zen and Intel processors. Sure, AMD showed a Zen-powered system running the upcoming Deus Ex running at 4K with a system powered by the Fury X, but the really impressive results where shown when comparing Zen to a Broadwell-E platform.
Using Blender to measure the performance of a rendering workload (a Zen CPU mockup of course), AMD ran an 8-core / 16-thread Zen processor at 3.0 GHz against an 8-core / 16-thread Broadwell-E processor at 3.0 GHz (likely a fixed clocked Core i7-6900K). The point of the demonstration was to showcase the IPC improvements of Zen and it worked: the render completed on the Zen platform a second or two faster than it did on the Intel Broadwell-E system.
Not much to look at, but Zen on the left, Broadwell-E on the right...
Of course there are lots of caveats: we didn’t setup the systems, I don’t know for sure that GPUs weren’t involved, we don’t know the final clocks of the Zen processors releasing in early 2017, etc. But I took two things away from the demonstration that are very important.
- The IPC of Zen is on-par or better than Broadwell.
- Zen will scale higher than 3.0 GHz in 8-core configurations.
AMD obviously didn’t state what specific SKUs were going to launch with the Zen architecture, what clock speeds they would run at, or even what TDPs they were targeting. Instead we were left with a vague but understandable remark of “comparable TDPs to Broadwell-E”.
Pricing? Overclocking? We’ll just have to wait a bit longer for that kind of information.
There is clearly a lot more for AMD to share about Zen but the announcement and showcase made this week with the early prototype products have solidified for me the capability and promise of this new microarchitecture. We have asked for, and needed, as an industry, a competitor to Intel in the enthusiast CPU space – something we haven’t legitimately had since the Athlon X2 days. Zen is what we have been pining over, what gamers and consumers have needed.
AMD’s processor stars might finally be aligning for a product that combines performance, efficiency and scalability at the right time. I’m ready for it –are you?

Tom Forsyth, who is currently at Oculus, was once on the core Larrabee team at Intel. Just prior to Intel's IDF conference in San Francisco, which Ryan is at and covering as I type this, Tom wrote a blog post that outlined the project and its design goals, including why it didn't hit market as a graphics device. He even goes into the details of the graphics architecture, which was almost entirely in software apart from texture units and video out. For instance, Larrabee was running FreeBSD with a program, called DirectXGfx, that gave it the DirectX 11 feature set -- and it worked on hundreds of titles, too.
Also, if you found the discussion interesting, then there is plenty of content from back in the day to browse. A good example is an Intel Developer Zone post from Michael Abrash that discussed software rasterization, doing so with several really interesting stories.

Tagged: VR, virtual reality, project alloy, Intel, augmented reality, AR
At the opening keynote to this summer’s Intel Developer Forum, CEO Brian Krzanich announced a new initiative to enable a completely untether VR platform called Project Alloy. Using Intel processors and sensors the goal of Project Alloy is to move all of the necessary compute into the headset itself, including enough battery to power the device for a typical session, removing the need for a high powered PC and a truly cordless experience.
This is indeed the obvious end-game for VR and AR, though Intel isn’t the first to demonstrate a working prototype. AMD showed the Sulon Q, an AMD FX-based system that was a wireless VR headset. It had real specs too, including a 2560x1440 OLED 90Hz display, 8GB of DDR3 memory, an AMD FX-8800P APU with R7 graphics embedded. Intel’s Project Alloy is currently using unknown hardware and won’t have a true prototype release until the second half of 2017.
There is one key advantage that Intel has implemented with Alloy: RealSense cameras. The idea is simple but the implications are powerful. Intel demonstrated using your hands and even other real-world items to interact with the virtual world. RealSense cameras use depth sensing to tracking hands and fingers very accurately and with a device integrated into the headset and pointed out and down, Project Alloy prototypes will be able to “see” and track your hands, integrating them into the game and VR world in real-time.
The demo that Intel put on during the keynote definitely showed the promise, but the implementation was clunky and less than what I expected from the company. Real hands just showed up in the game, rather than representing the hands with rendered hands that track accurately, and it definitely put a schism in the experience. Obviously it’s up to the application developer to determine how your hands would actually be represented, but it would have been better to show case that capability in the live demo.
Better than just tracking your hands, Project Alloy was able to track a dollar bill (why not a Benjamin Intel??!?) and use it to interact with a spinning lathe in the VR world. It interacted very accurately and with minimal latency – the potential for this kind of AR integration is expansive.
Those same RealSense cameras and data is used to map the space around you, preventing you from running into things or people or cats in the room. This enables the first “multi-room” tracking capability, giving VR/AR users a new range of flexibility and usability.
Though I did not get hands on with the Alloy prototype itself, the unit on-stage looked pretty heavy, pretty bulky. Comfort will obviously be important for any kind of head mounted display, and Intel has plenty of time to iterate on the design for the next year to get it right. Both AMD and NVIDIA have been talking up the importance of GPU compute to provide high quality VR experiences, so Intel has an uphill battle to prove that its solution, without the need for external power or additional processing, can truly provide the untethered experience we all desire.

Intel will allegedly be releasing another 14nm processor following Kaby Lake (which is itself a 14nm successor to Skylake) in 2018. The new processors are code named "Coffee Lake" and will be released alongside low power runs of 10nm Cannon Lake chips.
Not much information is known about Coffee Lake outside of leaked slides and rumors, but the first processors slated to launch in 2018 will be mainstream mobile chips that will come in U and HQ mobile flavors which are 15W to 28W and 35W to 45W TDP chips respectively. Of course, these processors will be built on a very mature 14nm process with the usual small performance and efficiency gains beyond Skylake and Kaby Lake. The chips should have a better graphics unit, but perhaps more interesting is that the slides suggest that Coffee Lake will be the first architecture where Intel will bring "hexacore" (6 core) processors into mainstream consumer chips! The HQ-class Coffee Lake processors will reportedly come in two, four, and six core variants with Intel GT3e class GPUs. Meanwhile the lower power U-class chips top out at dual cores with GT3e class graphics. This is interesting because Intel has previous held back the six core CPUs for its more expensive and higher margin HEDT and Xeon platforms.
Of course 2018 is also the year for Cannon Lake which would have been the "tock" in Intel's old tick-tock schedule (which is no more) as the chips will move to a smaller process node and then Intel would improve on the 10nm process from there in future architectures. Cannon Lake is supposed to be built on the tiny 10nm node, and it appears that the first chips on this node will be ultra low power versions for laptops and tablets. Occupying the ULV platform's U-class (15W) and Y-class (4.5W), Cannon Lake CPUs will be dual cores with GT2 graphics. These chips should sip power while giving comparable performance to Kaby and Coffee Lake perhaps even matching the performance of the Coffee Lake U processors!
Stay tuned to PC Perspective for more information!

Tagged: SoC, Snapdragon 821, snapdragon, qualcomm, adreno 530
Announced today, the Snapdragon 821 offers a modest CPU frequency increase over the Snapdragon 820, with clock speeds of up to 2.4 GHz compared to 2.2 GHz with the Snapdragon 820. The new SoC is still implementing Qualcomm's custom quad-core "Kryo" design, which is made up of two pairs of dual-core CPU clusters.
"What isn’t in this announcement is that the power cluster will likely be above 2 GHz and GPU clocks look to be around 650 MHz but without knowing whether there are some changes other than clock relative to Adreno 530 we can’t really estimate the performance of this part."
Specifics on the Adreno GPU were not mentioned in the official announcement. The 650 MHz GPU clock reported by Anandtech would offer a modest improvement over the SD820's 624 MHz Adreno 530 GPU. Additionally, the "power cluster" will reportedly move from 1.6 GHz with the SD820 to 2.0 GHz with the SD821.
No telling when this updated SoC will find its way into consumer devices, with the Snapdragon 820 currently available in the Samsung Galaxy S7/S7 Edge, LG G5, OnePlus 3, and a few others.

[H]ard|OCP has been conducting tests using a variety of CPUs to see how well DX12 distributes load between cores as compared to DX11. Their final article which covers the 6700K and 6950X was done a little differently and so cannot be directly compared to the previously tested CPUs. That does not lower the value of the testing, scaling is still very obvious and the new tests were designed to highlight more common usage scenarios for gamers. Read on to see how well, or how poorly, Ashes of the Singularity scales when using DX12.
"This is our fourth and last installment of looking at the new DX12 API and how it works with a game such as Ashes of the Singularity. We have looked at how DX12 is better at distributing workloads across multiple CPU cores than DX11 in AotS when not GPU bound. This time we compare the latest Intel processors in GPU bound workloads."

Tagged: Intel, kaby lake, iGPU, h.265, hevc, vp8, vp9, codec, codecs
Fudzilla isn't really talking about their sources, so it's difficult to gauge how confident we should be, but they claim to have information about the video codecs supported by Kaby Lake's iGPU. This update is supposed to include hardware support for HDR video, the Rec.2020 color gamut, and HDCP 2.2, because, if videos are pirated prior to their release date, the solution is clearly to punish your paying customers with restrictive, compatibility-breaking technology. Time-traveling pirates are the worst.
According to their report, Kaby Lake-S will support VP8, VP9, HEVC 8b, and HEVC 10b, both encode and decode. However, they then go on to say that 10-bit VP9 and 10-bit HEVC 10b does not include hardware encoding. I'm not too knowledgeable about video codecs, but I don't know of any benefits to encoding 8-bit HEVC Main 10. Perhaps someone in our comments can clarify.
