A look into AMD's future

Chuck Moore, CTO of AMD's Technology Group, gave a talk this week about AMD's plans for the future of their architecture.  As you might conjecture the focus was on the further integration of the CPU and GPU, with an eye on power consumption.  The hurdle he feels will be the tallest is the bandwidth for passing data back and forth between the two processors and he sees 3D stacks of memory sitting between the main system memory, the GPU and the CPU.  Once developed he feels that the stacks of memory should be able to increase the amount of available communication bandwidth to the point where tasks can be handed smoothly back and forth between the two processors depending on which is more effective at certain tasks.  Performance is not everything however, when The Register quotes Moore when he discusses the power requirements of a mid-range exascale class machine costing $200 million just to power and cool over a year, you begin to see the importance of bringing down power consumption and heat production.

"Because Advanced Micro Devices has not yet announced its 16-core "Interlagos" Opteron 6200 processors, it has to talk about something, and in situations like that, it is best to talk about the far-off future. And so AMD rounded up a bunch of its partners on Wednesday in San Francisco for a shindig to talk about the challenges of exascale computing."

Video Perspective: AMD A8-3850 vs Core i3-2105 on Battlefield 3

Subject: Graphics Cards, Processors | October 31, 2011 - 02:22 PM |
Tagged: video, sandy bridge, Intel, bf3, battlefield 3, APU, amd

Everyone is playing Battlefield 3 these days; we even had a virtual LAN party this weekend where forum members and PC Perspective team members played from about 10am until well after 1am ET. We have done more than our fair share of Battlefield 3 articles as well including hardware performance on high end graphics cards, multi-GPU scaling and more.  

We had some requests and questions about what was the lowest priced hardware you could play the game on and while we had run some tests on the GeForce 9800 GT, I decided to take a stab at running BF3 at its lowest settings with integrated graphics on Intel's Sandy Bridge processor and AMD's A-series APU.  Here were our test settings:

apubf31.png

We ran at a fairly low resolution of 1366x768 (both indicative of mobile resolutions as well as low-end hardware restrictions) and the Low in-game preset.  As it turns out this was the level at which the A8-3850 Llano APU was able to maintain an average around 30 FPS while the Intel Core i3-2105 (both priced around $140) was able to reach only a third of that.

With both systems coming in at the ~$450 mark, this could qualify as the lowest priced PC that is capable of getting you into the BF3 action!

A look at the 65W AMD A8-3800

Subject: General Tech | October 6, 2011 - 12:57 PM |
Tagged: amd, A8-3800, llano, APU, Turbo Core

When the A8-3850 hit the streets we were so accustomed to high powered CPUs that we barely blinked at the 100W power envelope it and the A6-3650 required.  That is a big change from just a few years ago when hitting or passing 100W tended to bring a lot of negative comments from reviewers.  AMD since released the lower powered A8-3800 and A6-3600, both of which have slightly lower CPU frequencies but the exact same graphics specifications.  The Tech Report took the A8-3800 out for a spin to examine not only the power draw but to see how well the Turbo Core feature works.  See how it turned out for AMD's newest Llano chips in the full review.

"We weren't terribly impressed with AMD's A8-3850 APU when we first reviewed it, in part because its 100W power envelope seemed rather large for a chip whose integrated graphics are a major selling point. Happily, the new A8-3800 slides into a cool 65W power envelope and adds Turbo Core clock frequency scaling. Can it win our approval? Keep reading to find out."

Oh Llano, wherefore art thou?

Subject: General Tech | October 3, 2011 - 12:14 PM |
Tagged: llano, APU, GLOBALFOUNDRIES, 28nm, 32nm, trinity, amd

Woe is AMD, as it becomes ever more obvious that Llano is not giving good yields at GLOBALFOUNDRIES.  Back in July the market noticed that while the new Llano chips were great at providing good enough graphics for a great price, they were very hard to find.  As a consumer you might be able to find a notebook to purchase for yourself but as a reseller who needs to buy processors in the thousands before considering that chip as a part of the new product line up you have been out of luck.  According to DigiTimes this will change in 2012 with the arrival of Trinity which will still use GLOBALFOUNDRIES 32nm process, turning to TSMC for the 28nm graphical portion.  The previous hope that the supply problems would be solved in September were obviously a little too optimistic.

"Supply of AMD's Llano APUs, affected by Globalfoundries's lower-than-expected 32nm yield rates, has been significantly limited and is unlikely to recover until the company's upcoming Trinity arrives in 2012, according to sources from motherboard players. When asked about the company's upcoming Trinity schedule, AMD Taiwan declined to comment on unannounced products.

AMD started suffering from Llano APU supply shortages in July due to the yield issues and the company originally expected the supply status to return to normal in September. However, judging from the current situation, the sources believe the company's supply volume is unlikely to meet client demand through the end of 2011.

The sources estimated that the yield rate issue should be resolved in 2012, when Trinity launches."

Bulldozer Infused Trinity APU Specifications Confirmed

Tagged: trinity, llano, bulldozer, APU, amd

AMD has not only started announcing quite a few future processors, but has also gone a bit crazy with all of the code names for said products. Admittedly, when the news broke that Trinity APU specifications were revealed, I had to do a bit of digging to figure out just what the Trinity APU was (exactly). In the end, the APU (accelerated processing unit) is similar in composition to Llano except with a bulldozer based CPU core and upgraded GPU. The bulldozer core aspect is what threw me for a bit of a loop in that I had a difficult time figuring out how the CPU core could be based on bulldozer when bulldozer hasn’t even been released ;).  Hopefully that long introduction helps somewhat in clearing up what Trinity is.

AMD_logo.jpg

Specifically, the new Trinity APU will debut with AMD’s new “Piledriver” (more code names!) architecture, and include a Radeon HD 7000 series GPU and Bulldozer based CPU core. Futher, the Trinity APU will come in both notebook and desktop flavors titled “Comal” and “Virgo” respectively. AMD notes that the improvements in the CPU and GPU cores will result in up to a 50% performance increase over the current Llano A Series APUs. While the 50% number is measuring pure gigaflop performance, even if the real world speed increase is not as noticeable in everyday usage, it is still a nice bump in performance.

On the availability front, AMD has slated the processor for release in 2012; however, Semi Accurate believes that the APU may well debut much sooner than expected. The site further quoted sources who stated that “CES is a distinct possibility for a soft launch, and maybe more.” More tidbits of information can be had here.

Zotac has made a name for itself in the small form factor sector of the computer market. Their ZBOX computers are designed to use little power but have enough horsepower to drive smooth HD video playback. The new ZBOX nano AD10 series is a new line in the Zotac family that shares the media-centric traits of its predecessors. The Nano AD10 series PCs are some of the smallest the company has released, and shrinks the ZBOX form factor while packing in new home theater PC features.

ZBOX-NANO-AD10_image4e5df0c9e23bb.jpg

Inside the tiny frame measuring 127mm x 127mm x 45mm, is a 1.8 GHz dual core AMD Brazos E-350 APU, DDR3 SO-DIMM slot, and space for a 2.5” SATA 3 (6Gbps) hard drive. Connectivity options include Gigabit Ethernet, 802.11n WiFi, Bluetooth 3.0, HDMI, DisplayPort, two USB 2.0, and two USB 3.0 ports. Further, the ZBOX computer features a built in IR (infra-red) receiver and media center remote in addition to an eSATA port and a 6-in-1 media card reader. On the audio front, the media center PC supports on-board analog stereo and 7.1 channel digital audio (LPCM and Bitstream via HDMI).

There are currently two models in the AD10 series, the AD10 and the AD10 Plus. The AD10 model allows for a bit more user customization by leaving it up to the user to add their own RAM and hard drive of choice to the mini PC. The AD10 Plus on the other hand, is the same as the AD10 except for the fact that it includes a 2 GB DDR3 SO-DIMM and a 320 GB 5400 RPM hard drive. Both models come with the media center remote, USB IR receiver (in addition to the built in receiver), and VESA mount.

Media center PCs are getting smaller every day, and the new Nano AD10 series from Zotac is no different. Thanks to the APU (especially the GPU), and hardware accelerated video decoding, it will deliver plenty of horsepower for all your home theater PC needs. Unfortunately, there was no word on MSRP or availability at the time of publication. Stay tuned for an update.

Checking A8-3850 overclocking capability 7 times

Subject: Processors | August 30, 2011 - 12:50 PM |
Tagged: a8-3850, amd, llano, overclocking, APU

Legit Reviews decide that they really wanted to be able to show the overclocking results you can expect from the AMD A8-3850, so they picked up eight of the chips to test each for overclocking ability.  There have been examples in the past of chips with a wide variety of overclocking limits which was often decided by the chip revision but not in all cases.  The test results show that all but two of the chips hit a stability issue when being pushed beyond 3679.5MHz, so you can take that as the most likely result that your chip will provide.  The two outlying chips will be exceptional, in one case in a bad way which you can see in the full review.

BR_a8-3850-apu-tray-1.jpg

"When AMD released the 'Lynx' desktop platform back in June 2011, our motherboard reviewer ran into some bad luck when overclocking the processor. When you get a new platform setup for the very first time you really don't know what to expect and it does take some time to learn all the quirks and nuances of a new processor and motherboard. We recently ordered in six more processors and then overclocked all seven of them to see what the best one would be for our test system!"

AMD Adds Three New Fusion APUs to Mobile Lineup

Subject: Processors | August 22, 2011 - 10:53 AM |
Tagged: mobile, fusion, E-Series, APU, amd

AMD today announced three new Accelerated Processing Units (APU) to bolster up the mobile lineup. Specifically, two new E-Series and one new C-Series APU are inserting themselves into the lineup. The new chips bring enhanced graphic capabilities, HDMI 1.4a, and DDR3 1333 support. "Today's PC users want stunning HD graphics and accelerated performance with all-day battery life and that's what AMD Fusion APUs deliver," said Chris Cloran, vice president and general manager, Client Division, AMD.

According to MaximumPC, the new E-450 APU takes the top slot, bringing two CPU cores clocked at 1.65GHz, a Radeon HD 6320 GPU clocked at a base of 508MHz and maximum of 600MHz, and a power sipping TDP of 18 watts. The second new E-Series APU carries the same 18 watt TDP and dual CPU cores as the E-450; however, it is clocked at a lower 1.3GHz. Further, the chip’s Radeon HD 6310 GPU is clocked at 488MHz.  The new E-Series APUs feature battery life increases to the tune of up to 10.5 hours of Windows idle time.

The new C-Series APU is the C-60, and is a 1GHz dual core chip with a Radeon HD 6290 GPU. The APU is able to turbo its CPU cores to a maximum of 1.33GHz, while the GPU has a base clock of 276MHz and a maximum clock speed of 400MHz. Further, the chip has a 9 watt TDP, and boasts 12.25 hours of “resting battery life,” which AMD benchmarked using Windows Idle on a C-60 based netbook.

Currently, AMD has shipped more than 12 million APUs, and more than five million of the C-Series and E-Series processors in Q2 2011. More information on the specific benchmarking metrics AMD used can be found here.
