Clean Sheet and New Focus

It is no secret that AMD has been struggling for some time.  The company has had success through the years, but it seems that the last decade has been somewhat bleak in terms of competitive advantages.  The company has certainly made an impact in throughout the decades with their 486 products, K6, the original Athlon, and the industry changing Athlon 64.  Since that time we have had a couple of bright spots with the Phenom II being far more competitive than expected, and the introduction of very solid graphics performance in their APUs.

Sadly for AMD their investment in the “Bulldozer” architecture was misplaced for where the industry was heading.  While we certainly see far more software support for multi-threaded CPUs, IPC is still extremely important for most workloads.  The original Bulldozer was somewhat rushed to market and was not fully optimized, while the “Piledriver” based Vishera products fixed many of these issues we have not seen the non-APU products updated to the latest Steamroller and Excavator architectures.  The non-APU desktop market has been served for the past four years with 32nm PD-SOI based parts that utilize a rebranded chipset base that has not changed since 2010.

Four years ago AMD decided to change course entirely with their desktop and server CPUs.  Instead of evolving the “Bulldozer” style architecture featuring CMT (Core Multi-Threading) they were going to do a clean sheet design that focused on efficiency, IPC, and scalability.  While Bulldozer certainly could scale the thread count fairly effectively, the overall performance targets and clockspeeds needed to compete with Intel were just not feasible considering the challenges of process technology.  AMD brought back Jim Keller to lead this effort, an industry veteran with a huge amount of experience across multiple architectures.  Zen was born.

 

Hot Chips 28

This year’s Hot Chips is the first deep dive that we have received about the features of the Zen architecture.  Mike Clark is taking us through all of the changes and advances that we can expect with the upcoming Zen products.

Zen is a clean sheet design that borrows very little from previous architectures.  This is not to say that concepts that worked well in previous architectures were not revisited and optimized, but the overall floorplan has changed dramatically from what we have seen in the past.  AMD did not stand still with their Bulldozer products, and the latest Excavator core does improve upon the power consumption and performance of the original.  This evolution was simply not enough considering market pressures and Intel’s steady improvement of their core architecture year upon year.  Zen was designed to significantly improve IPC and AMD claims that this product has a whopping 40% increase in IPC (instructions per clock) from the latest Excavator core.

AMD also has focused on scaling the Zen architecture from low power envelopes up to server level TDPs.  The company looks to have pushed down the top end power envelope of Zen from the 125+ watts of Bulldozer/Vishera into the more acceptable 95 to 100 watt range.  This also has allowed them to scale Zen down to the 15 to 25 watt TDP levels without sacrificing performance or overall efficiency.  Most architectures have sweet spots where they tend to perform best.  Vishera for example could scale nicely from 95 to 220 watts, but the design did not translate well into sub-65 watt envelopes.  Excavator based “Carrizo” products on the other hand could scale from 15 watts to 65 watts without real problems, but became terribly inefficient above 65 watts with increased clockspeeds.  Zen looks to address these differences by being able to scale from sub-25 watt TDPs up to 95 or 100.  In theory this should allow AMD to simplify their product stack by offering a common architecture across multiple platforms.

GlobalFoundries Will Allegedly Skip 10nm and Jump to Developing 7nm Process Technology In House (Updated)

Subject: Processors | August 20, 2016 - 03:06 PM |
Tagged: Semiconductor, lithography, GLOBALFOUNDRIES, global foundries, euv, 7nm, 10nm

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!

Bristol Ridge Takes on Mobile: E2 Through FX

It is no secret that AMD has faced an uphill battle since the release of the original Core 2 processors from Intel.  While stayed mostly competitive through the Phenom II years, they hit some major performance issues when moving to the Bulldozer architecture.  While on paper the idea of Chip Multi-Threading sounded fantastic, AMD was never able to get the per thread performance up to expectations.  While their CPUs performed well in heavily multi-threaded applications, they just were never seen in as positive of a light as the competing Intel products.

br_01.png

The other part of the performance equation that has hammered AMD is the lack of a new process node that would allow it to more adequately compete with Intel.  When AMD was at 32 nm PD-SOI, Intel had introduced its 22nm TriGate/FinFET.  AMD then transitioned to a 28nm HKMG planar process that was more size optimized than 32nm, but did not drastically improve upon power and transistor switching performance.

So AMD had a double whammy on their hands with an underperforming architecture and limitted to no access to advanced process nodes that would actually improve their power and speed situation.  They could not force their foundry partners to spend billions on a crash course in FinFET technology to bring that to market faster, so they had to iterate and innovate on their designs.

Bristol Ridge is the fruit of that particular labor.  It is also the end point to the architecture that was introduced with Bulldozer way back in 2011.

Gaming at the low end, checking out the Athlon X4 880K

Tagged: Wraith, Godavari, GLOBALFOUNDRIES, FM2+, amd, X4 880K

Remember that FM2+ refresh which Josh informed you about back in March?  The APUs have started arriving on test benches and can be benchmarked independently to see what this ~$100 processor and the Wraith cooler are capable of.  Neoseeker compares the new 880K against the older FX-4350 in a long series of benchmarks which show the 880K to be the better part in most cases.  There are some interesting exceptions to this, in which the FX-4350's slightly higher frequency allows it to pull ahead by a small margin so there are cases where the less expensive chip would make sense.  Read the full review to see which chip makes more sense for you.

"Today we take a look at the AMD Athlon X4 880K, a quad-core FM2+ processor with 4.0/4.2GHz base/Turbo clocks and unlocked multiplier priced at under $100 USD. It's designed for enthusiasts on a budget looking for the fastest multi-core Athlon processor yet without any integrated GPU to add to the cost. It even shares the 95W TDP of AMD's higher-end APUs for optimized power consumption that further leads to more overclocking headroom."

IBM is feeling Powerful in the Core Wars, details on the Power9 architecture have arrived

Subject: General Tech | April 7, 2016 - 03:43 PM |
Tagged: GLOBALFOUNDRIES, IBM, power9

IBM's Power9 processor is scheduled to appear on the scene just over a year from now and finally we have some details about what it will be.  Firstly the core count is to be two higher than Intel, 24 cores and is optimized for use in two socket servers.  The chips are 14nm FinFETs fabbed by GLOBALFOUNDRIES which will be compatible with modern industry standards including DDR4, PCIe 4.0 and NVLink 2.0 so you can even take advantage of Jen-Hsun's latest products. 

The list of customers is quite impressive, Google has moved to Power8 already and described changing to the infrastructure as simple as flipping a switch,  the US Department of Energy will build their next HPCs using Power9 and Rackspace is currently working with Google to develop Power9 server blueprints for the Open Compute Project. 

Several Chinese companies will take advantage of those OpenPower blueprints to develop their own 'partner chips', Power8 and 9 architecture which will be using 10nm gates in 2018 to 2020.  This is somewhat amusing considering the shipping of Xeon processors to China has been banned by the US Government.  Check out more of the slides from IBM's presentation at The Register.

power_roadmap_crop.jpg

"IBM's Power9 processor, due to arrive in the second half of next year, will have 24 cores, double that of today's Power8 chips, it emerged today.

Meanwhile, Google has gone public with its Power work – confirming it has ported many of its big-name web services to the architecture, and that rebuilding its stack for non-Intel gear is a simple switch flip."

Clockspeed Jump and More!

On March 1st AMD announced the availability of two new processors as well as more information on the A10 7860 APU.

The two new units are the A10-7890K and the Athlon X4 880K.  These are both Kaveri based parts, but of course the Athlon has the GPU portion disabled.  Product refreshes for the past several years have followed a far different schedule than the days of yore.  Remember back in time when the Phenom II series and the competing Core 2 series would have clockspeed updates that were expected yearly, if not every half year with a slightly faster top end performer to garner top dollar from consumers?

amd_lineup.png

Things have changed, for better or worse.  We have so far seen two clockspeed bumps for the Kaveri /Godavari based APU.  Kaveri was first introduced over two years ago with the A10-7850K and the lower end derivatives.  The 7850K has a clockspeed that ranges from 3.7 GHz to the max 4 GHz with boost.  The GPU portion is clocked at 720 MHz.  This is a 95 watt TDP part that is one of the introductory units from GLOBALFOUNDRIES 28 nm HKMG process.

Today the new top end A10-7890K is clocked at 4.1 GHz to 4.3 GHz max.  The GPU receives a significant boost in performance with a clockspeed of 866 MHz.  The combination of CPU and GPU clockspeed increases push the total performance of the part exceeding 1 TFLOPs.  It features the same dual module/quad core Godavari design as well as the 8 GCN Units.  The interesting part here is that the APU does not exceed the 95 watt TDP that it shares with the older and slower 7850K.  It is also a boost in performance from last year’s refresh of the A10-7870K which is clocked 200 MHz slower on the CPU portion but retains the 866 MHz speed of the GPU.  This APU is fully unlocked so a user can easily overclock both the CPU and GPU cores.

amd_7890k.png

The Athlon X4 880K is still based on the Godavari family rather than the Carizzo update that the X4 845 uses.  This part is clocked from 4.0 to 4.2 GHz.  It again retains the 95 watt TDP rating of the previous Athlon X4 CPUs.  Previously the X4 860K was the highest clocked unit at 3.7 GHz to 4.0, but the 880K raises that to 4 to 4.2 GHz.  A 300 MHz gain in base clock is pretty significant as well as stretching that ceiling to 4.2 GHz.  The Godavari modules retain their full amount of L2 cache so the 880K has 4 MB available to it.  These parts are very popular with budget enthusiasts and gaming builds as they are extremely inexpensive and perform at an acceptable level with free overclocking thrown in.

AMD Polaris Architecture Coming Mid-2016

In early December, I was able to spend some time with members of the newly formed Radeon Technologies Group (RTG), which is a revitalized and compartmentalized section of AMD that is taking over all graphics work. During those meetings, I was able to learn quite a bit about the plans for RTG going forward, including changes for AMD FreeSync and implementation of HDR display technology, and their plans for the GPUOpen open-sourced game development platform.  Perhaps most intriguing of all: we received some information about the next-generation GPU architecture, targeted for 2016.

Codenamed Polaris, this new architecture will be the 4th generation of GCN (Graphics Core Next), and it will be the first AMD GPU that is built on FinFET process technology. These two changes combined promise to offer the biggest improvement in performance per watt, generation to generation, in AMD’s history.

polaris-5.jpg

Though the amount of information provided about the Polaris architecture is light, RTG does promise some changes to the 4th iteration of its GCN design. Those include primitive discard acceleration, an improved hardware scheduler, better pre-fetch, increased shader efficiency, and stronger memory compression. We have already discussed in a previous story that the new GPUs will include HDMI 2.0a and DisplayPort 1.3 display interfaces, which offer some impressive new features and bandwidth. From a multimedia perspective, Polaris will be the first GPU to include support for h.265 4K decode and encode acceleration.

polaris-15.jpg

This slide shows us quite a few changes, most of which were never discussed specifically that we can report, coming to Polaris. Geometry processing and the memory controller stand out as potentially interesting to me – AMD’s Fiji design continues to lag behind NVIDIA’s Maxwell in terms of tessellation performance and we would love to see that shift. I am also very curious to see how the memory controller is configured on the entire Polaris lineup of GPUs – we saw the introduction of HBM (high bandwidth memory) with the Fury line of cards.

Rumor: Abu Dhabi Fund Seeks to Sell GlobalFoundries

Subject: General Tech | November 29, 2015 - 04:45 PM |
Tagged: GLOBALFOUNDRIES

Several years ago, AMD spun off their chip manufacturing infrastructure into a company, which was named GlobalFoundries, and became a fabless integrated circuit designer. This transaction meant that AMD would be free to shop around when they needed something printed, and they wouldn't need to pay for the upfront expenses. That burden would be placed on the shoulders of stakeholders in GlobalFoundries, and of course the revenue they acquire from their larger pool of customers.

Speaking of their stakeholders, GlobalFoundries is wholly owned by Advanced Technology Investment Company, which is owned by Mubadala Development Company, which is owned by the government of Abu Dhabi. GlobalFoundries merged with Chartered Semiconductor and was actually paid by IBM to acquire their fab business, at a reward of $1.5 billion USD and binding IBM to a ten-year exclusivity deal for server processors, which helped bolster the company. Oil prices have been fluctuating though, and sources tell Bloomberg that Abu Dhabi is interested in selling some or all of GlobalFoundries at a valuation of around $15-20 billion USD.

The report stops there, without declaring any potential candidates, but speculation doesn't. A lot of it just sounds like listing names who have lots of cash. If the source is even accurate, we don't know who are involved or how serious they are.
