AMD Keeps Q1 Interesting

CES 2016 was not a watershed moment for AMD.  They showed off their line of current video cards and, perhaps more importantly, showed off working Polaris silicon, which will be their workhorse for 2016 in the graphics department.  They did not show off Zen, a next generation APU, or any AM4 motherboards.  The CPU and APU world was not presented in a way that was revolutionary.  What they did show off, however, hinted at the things to come to help keep AMD relevant in the desktop space.

It was odd to see an announcement about the stock cooler that AMD was introducing, but when we learned more about it, the more important it was for AMD’s reputation moving forward.  The Wraith cooler is a new unit to help control the noise and temperatures of the latest AMD CPUs and select APUs.  This is a fairly beefy unit with a large, slow moving fan that produces very little noise.  This is a big change from the variable speed fans on previous coolers that could get rather noisy and leave temperatures that were higher in range than are comfortable.  There has been some derision aimed at AMD for providing “just a cooler” for their top end products, but it is a push that is making them more user and enthusiast friendly without breaking the bank.

Socket AM3+ is not dead yet.  Though we have been commenting on the health of the platform for some time, AMD and its partners work to improve and iterate upon these products to include technologies such as USB 3.1 and M.2 support.  While these chipsets are limited to PCI-E 2.0 speeds, the four lanes available to most M.2 controllers allows these boards to provide enough bandwidth to fully utilize the latest NVMe based M.2 drives available.  We likely will not see a faster refresh on AM3+, but we will see new SKUs utilizing the Wraith cooler as well as a price break for the processors that exist in this socket.

Sony Unlocks One More Jaguar Core in the PS4

Subject: Systems | November 29, 2015 - 09:12 PM |
Tagged: sony, playstation 4, ps4, amd, Jaguar, APU

Of the eight Jaguar cores that Sony added to the PlayStation 4 APU, two were locked down the console's operating system and other tasks. This left the developer with six to push their workloads through. This was the same as the Xbox One until Microsoft released an update last year, which unlocked one to give seven.

NeoGAF users report that, allegedly, PlayStation 4 games can now utilize seven of the eight cores after a recent SDK update from Sony. They source a recent changelist for FMOD, a popular audio management library for PC, mobile, and console platforms, which references targeting “the newly unlocked 7th core.”

Since this is not an official Sony announcement, at least not publicly, we don't know some key details. For instance, is the core completely free, or will the OS still push tasks on it during gameplay? Will any features be disabled if the seventh core is targeted? How frequently will the seventh core be blocked, if ever? What will happen if you block it, if anything? The Xbox One is said to use about 20% of their unlocked seventh core for Microsoft-related tasks, and claiming the remaining 80% is said to disable voice recognition and Kinect features.

The Xbox One and PlayStation 4 are interesting devices to think about. They go low frequency, but wide, in performance, similar to many mobile devices. They also utilize a well-known instruction set, x86, which obviously has a huge catalog of existing libraries and features. I don't plan on every buying another console, but they move with the industry and has a fairly big effect on it (albeit much less than previous generations).

GlobalFoundries has today officially announced their success with sample 14 nm FinFET production for upcoming AMD products.

GlobalFoundries licensed 14 nm LPE and LPP technology from Samsung in 2014, and were producing wafers as early as April of this year. At the time a GF company spokesperson was quoted in this report at KitGuru, stating "the early version (14LPE) is qualified in our fab and our lead product is yielding in double digits. Since 2014, we have taped multiple products and testchips and are seeing rapid progress, in yield and maturity, for volume shipments in 2015." Now they have moved past LPE (Low Power Early) to LPP (Low Power Plus), with new products based on the technology slated for 2016:

"AMD has taped out multiple products using GLOBALFOUNDRIES’ 14nm Low Power Plus (14LPP) process technology and is currently conducting validation work on 14LPP production samples.  Today’s announcement represents another significant milestone towards reaching full production readiness of GLOBALFOUNDRIES’ 14LPP process technology, which will reach high-volume production in 2016."

GlobalFoundries was originally the manufacturing arm of AMD, and has continued to produce the companies processors since the spin-off in 2012. AMD's current desktop FX-8350 CPU was manufactured on 32 nm SOI, and more recently APUs such as the A10-7850K have been produced at 28 nm - both at GlobalFoundries. Intel's latest offerings such as the flagship 6700K desktop CPU are produced with Intel's 14nm process, and the success of the 14LPP production at GlobalFoundries has the potential to bring AMD's new processors closer parity with Intel (at least from a lithography standpoint).

A new report points to an entry from the USB implementors forum, which shows an unreleased AMD Bristol Ridge SoC.

Bristol Ridge itself is not news, as the report at Computer Base observes (translation):

"A leaked roadmap had previously noted that Bristol Ridge is in the coming year soldered on motherboards for notebooks and desktop computers in special BGA package FP4."

(USB.org via Computer Base)

But there is something different about this chip as the report point out the model name FX-9830P pictured in the USB.org screen grab is consistent with the naming scheme for notebook parts, with the highest current model being FX-8800P (Carrizo), a 35W 4-thread Excavator part with 512 stream processors from the R7 GPU core.

No details are available other than information from a leaked roadmap (above), which points to Bristol Ridge as an FP4 BGA part for mobile, with a desktop variant for socket FM3 that would replace Kaveri/Godavari (and possibly still an Excavator part). New cores are coming in 2016, and we'll have to wait and see for additional details (or until more information inevitably leaks out).

Update, 11/06/15: WCCFtech expounds on the leak:

“Bristol Ridge isn’t just limited to mobility platforms but will also be featured on AM4 desktop platform as Bristol Ridge will be the APU generation available on desktops in 2016 while Zen would be integrated on the performance focused FX processors.”

WCCFtech’s report also included a link to this SiSoftware database entry for an engineering sample of a dual-core Stoney Ridge processor, a low-power mobile part with a 2.7 GHz clock speed. Stoney Ridge will reportedly succeed Carrizo-L for low-power platforms.

The report also provided this chart to reference the new products:

Rumor: Apple to Use Custom AMD SoC for Next-Gen iMac

Subject: Processors | October 19, 2015 - 11:28 AM |
Tagged: Zen, SoC, processor, imac, APU, apple, amd

Rumor: Apple to Use AMD SoC for Next-Gen iMac News about AMD has been largely depressing of late, with the introduction of the R9 Fury/Fury X and Nano graphics cards a bright spot in the otherwise tumultuous year that was recently capped by a $65 million APU write down. But one area where AMD has managed to earn a big win has been the console market, where their APUs power the latest machines from Microsoft and Sony. The combination of CPU and a powerful GPU on a single chip is ideal for those small form-factor designs, and likewise it would be ideal for a slim all-in-one PC. But an iMac?

IMAC.jpg

A report from WCCFtech today points to the upcoming Zen architecture from AMD as a likely power source for a potential custom SoC:

"A Semi-custom SOC x86 for the iMac would have to include a high performance x86 component, namely Zen, in addition to a graphics engine to drive the visual experience of the device. Such a design would be very similar to the current semi-custom Playstation 4 and XBOX ONE Accelerated Processing Units, combining x86 CPU cores with a highly capable integrated graphics solution."

Those who don't follow Apple probably don't know the company switched over almost exclusively to AMD graphics a short time ago, with NVIDIA solutions phased out of all discrete GPU models. Whether politically motivated or simply the result of AMD providing what Apple wanted from a hardware/driver standpoint I can't say, but it's still a big win for AMD considering Apple's position as one of the largest computer manufacturers - even though its market share is very low in the highly fragmented PC market overall. And while Apple has exclusively used Intel processors in its systems since transitioning away from IBM's PowerPC beginning in 2006, the idea of an AMD custom APU makes a lot of sense for the company, especially for their size and heat constrained iMac designs.

Whether or not you'd ever consider buying an iMac - or any other computer from Apple, for that matter - it's still important for the PC industry as a whole that AMD continues to find success and provide competition for Intel. Consumers can only benefit from the potential for improved performance and reduced cost if competition heats up between Intel and AMD, something we really haven't seen on the CPU front in a few years now. With CEO Lisa Su stating that AMD "had secured two new semi-custom design wins" In their recent earnings call it could very well be that we will see Zen in future iMacs, or in other PC all-in-one solutions for that matter.

Regardless, it will be exciting to see some good competition from AMD, even if we will have to wait quite a while for it. Zen isn't ready yet and we have no indication that any such product would be introduced until later next year. It will be interesting to see what Intel might do to compete given their resources. 2016 could be interesting.

Lenovo has unveiled their reinvented their ideapad (now all lowercase) lineup at IFA 2015 in Berlin, and the new laptops feature updated processors including Intel Braswell and Skylake, as well as some discrete AMD and NVIDIA GPU options.

IdeaPad100S.png

At the entry-level price-point we find the ideapad 100S which does not contain one of the new Intel chips, instead running an Intel Atom Z3735F CPU and priced accordingly at just $189 for the 11.6” version and $259 for the 14” model. While low-end specs (2GB RAM, 32GB/64GB eMMC storage, 1366x768 screen) aren’t going to blow anyone away, these at least provide a Windows 10 alternative to a Chromebook at about the same cost, and to add some style Lenovo is offering the laptop in four colors: blue, red, white, and silver.

Ideapad300s.png

Moving up to the 300S we find a 14” laptop (offered in red, black, or white) with Intel Pentium Braswell processors up to the quad-core N3700, and the option of a FHD 1920x1080 display. Memory and storage options will range up to 8GB DDR3L and up to either 256GB SSD or 1TB HDD/SSHD. At 0.86" thick the 300S weighs 2.9 lbs, and prices will start at $479.

A lower-cost ideapad 300, without the “S” and with more basic styling, will be available in sizes ranging from 14” to 17” and prices starting between $399 and $549 for their respective models. A major distinction will be the inclusion of both Braswell and Intel 6th Gen Skylake CPUs, as well at the option of a discrete AMD GPU (R5 330M). 

IdeaPad500S.png

Last we have the ideapad 500S, available in 13.3”, 14”, and 15.6” versions. With Intel 6th Gen processors up to Core i7 like the 300S, these also offer optional NVIDIA GPUs (GTX 920M for the 13.3", 940M for the 14"+) and up to FHD screen resolution. Memory and storage options range up to 8GB DDR3L and up to either 256GB SSD or 1TB HDD/SSHD, and the 500S is a bit thinner and lighter than the 300S, with the 13.3” version 0.76” thick and 3.4 lbs, moving up to 0.81” and 4.6 lbs with the 15.6” version.

A non-S version of the ideapad 500 will also be available, and this will be the sole AMD CPU representative with the option of an all-AMD solution powered by up to the A10-7300 APU, or a combination of R7 350M graphics along with 6th Gen Intel Core processors. 14” and 15” models will be available starting at $399 for the APU model and $499 with an Intel CPU.

All of the new laptops ship with Windows 10 as Microsoft’s newest OS arrived just in time for the back-to-school season.

AMD A8-7670K (Godavari) Launches with Steamroller

Subject: Processors | July 22, 2015 - 09:56 PM |
Tagged: amd, APU, Godavari, a8, a8-7670k

AMD's Godavari architecture is the last one based on Bulldozer, which will hold the company's product stack over until their Zen architecture arrives in 2016. The A10-7870K was added a month ago, with a 95W TDP at a MSRP of $137 USD. This involved a slight performance bump of +200 MHz at its base frequency, but a +100 MHz higher Turbo than its predecessor when under high load. More interesting, it does this at the same TDP and the same basic architecture.

amd-2015-A8-7670K+Blog+Post+Benchmark+Graphic+1.JPG

Remember that these are AMD's benchmarks.

The refresh has been expanded to include the A8-7670K. Some sites have reported that this uses the Excavator architecture as seen in Carrizo, but this is not the case. It is based on Steamroller. This product has a base clock of 3.6 GHz with a Turbo of up to 3.9 GHz. This is a +300 MHz Base and +100 MHz Turbo increase over the previous A8-7650K. Again, this is with the same architecture and TDP. The GPU even received a bit of a bump, too. It is now clocked at 757 MHz versus the previous generation's 720 MHz with all else equal, as far as I can tell. This should lead to a 5.1% increase in GPU compute throughput.

The A8-7670K just recently launched for an MSRP of $117.99. This 20$ saving should place it in a nice position below the A10-7870K for mainstream users.

Carrizo reveals itself

If you skipped reading Scott's look at the new AMD Carrizo processor you have done yourself a disfavour and should read through his look at AMD's recent history and the evolution of Bulldozer and Steamroller into Excavator.  It will help you understand The Tech Report's look into the new architecture and the AMD provided benchmarks which you can check out here.  A lot of the new architecture is a refinement of previous chips but the Tonga based GPU portion is completely new and looks to be an impressive improvement, especially on these 15W and 30W chips.  It will be very interesting to see how they fare against the Iris Pro on Intel's new Broadwell chips in systems without a discrete GPU.

carriro-specs.jpg

"The Carrizo processor is AMD's follow-on to Kaveri and a direct competitor to Intel's Broadwell CPUs. After a lengthy prelude, AMD is officially taking the wraps off of Carrizo today at the Computex trade show in Taipei. The firm expects laptops based on Carrizo to be available near the end of this month, and now that the chip is official, we know a number of juicy details about it that had previously been murky."

Digging into a specific market

A little while ago, I decided to think about processor design as a game. You are given a budget of complexity, which is determined by your process node, power, heat, die size, and so forth, and the objective is to lay out features in the way that suits your goal and workload best. While not the topic of today's post, GPUs are a great example of what I mean. They make the assumption that in a batch of work, nearby tasks are very similar, such as the math behind two neighboring pixels on the screen. This assumption allows GPU manufacturers to save complexity by chaining dozens of cores together into not-quite-independent work groups. The circuit fits the work better, and thus it lets more get done in the same complexity budget.

amd-2015-carrizo-63mil.jpg

Carrizo is aiming at a 63 million unit per year market segment.

This article is about Carrizo, though. This is AMD's sixth-generation APU, starting with Llano's release in June 2011. For this launch, Carrizo is targeting the 15W and 35W power envelopes for $400-$700 USD notebook devices. AMD needed to increase efficiency on the same, 28nm process that we have seen in their product stack since Kabini and Temash were released in May of 2013. They tasked their engineers to optimize their APU's design for these constraints, which led to dense architectures and clever features on the same budget of complexity, rather than smaller transistors or a bigger die.

15W was their primary target, and they claim to have exceeded their own expectations.

Backing up for a second. Beep. Beep. Beep. Beep.

When I met with AMD last month, I brought up the Bulldozer architecture with many individuals. I suspected that it was a quite clever design that didn't reach its potential because of external factors. As I started this editorial, processor design is a game and, if you can save complexity by knowing your workload, you can do more with less.

amd-2015-carrizo-3.jpg

Bulldozer looked like it wanted to take a shortcut by cutting elements that its designers believed would be redundant going forward. First and foremost, two cores share a single floating point (decimal) unit. While you need some floating point capacity, upcoming workloads could use the GPU for a massive increase in performance, which is right there on the same die. As such, the complexity that is dedicated to every second FPU can be cut and used for something else. You can see this trend throughout various elements of the architecture.

Read on for more about what Carrizo is, and what it came from to get here.

AMD has new APUs and new pricing for the ones already on the market

Subject: General Tech | May 7, 2015 - 02:17 PM |
Tagged: amd, Carrizo-L, A8-7410, A6-7310, E2-7110, E1-7010, APU

AMD has provided information on their new Carrizo-L based 7000 series of chips featuring the A8-7410, A6-7310 and the A4-7210 as well as the E2-7110 and E1-7010.  The two E series chips replace the low powered Beema APS, the E1-6010 and E2-6110 which were found in All-in-One machines with the new E2-7110 being the first of that series to have four cores.  The other three models are new desktop chips with newer graphics cores, the full feature set you would expect and slightly higher TDPs than the E-Series.

The existing AMD A-Series Desktop APUs have seen a price reduction today with prices for the top end A10-7850K reduced to $127 with the low end A4-7300 costing a mere $42 which helps AMD's positioning as a supplier in the lower end of the market.  You can see the entire price list as well as some information about the new R300 series of GPUs in their post.

"The AMD A-series APU are also the world’s best SoCs for DirectX 12, as independent testing showed a 41% framerate increase under DirectX 12 – read more in the AMD blog here. Additionally, using DirectX 12 the AMD A-series APU was able to demonstrate an incredible 511% increase in performance per watt.

Finally, with a suitably equipped AMD socket FM2+ motherboard featuring DisplayPort, AMD A-series APUs also support AMD FreeSync to deliver all the incredible experience benefits detailed in our AMD blog here."
