AMD Unleashes the 990FX: Paving the way for Bulldozer
Word of the AMD 990FX chipset first came around the end of last year. Speculation was brisk as to what new features it would bring, and when exactly it would help to usher in the age of Bulldozer to the world. Most thought that it would be a shrink of the then current 890FX, and the new SB950 southbridge would have improvements to the SATA 6G controller, as well as a native USB 3.0 implementation. Today we finally get to see the reality of the situation. It is not groundbreaking, nor is it altogether exciting, but it is certainly interesting.
The 990FX and SB950 chips are identical to the previous 890FX and SB850. They are the same silicon. For those hoping for new technology will be disappointed. But all is not lost! AMD did increase the HyperTransport specification from 3.0 to 3.1, which allows the HT bus to run at 6.4 GTPS as compared to the older 5.2 GTPS. This is in place to allow the upcoming Bulldozer chips to run the northbridge portion of the chip up to 3.2 GHz, and to give the CPU more bandwidth between the different busses on the board (eg. SATA, USB 3.0, and PCI-E connections).

While talking up the new 900-series of chipset and the branding for the upcoming AMD Llano APU launch, AMD did surprise us by showing off a bit more of the future than typical. Rick Bergman, general manager of the AMD Product Group, pulled a Trinity-based APU out of his pocket to demonstrate the conviction of staying on a "one-APU-per-year" cycle in the years to come.
While it looks just like any other AMD processors from a distance, this Trinity APU is based on the Bulldozer x86 architecture (which will see the first release as a CPU only later this year) and combines some amount of SIMD-units (aka Radeon cores) for a CPU/GPU combo. This will be the part that succeeds Llano, due out in a few short days.
This roadmap shows the cadence of once a year will be the norm for AMD going forward and that AMD plans to introduce an APU for the tablet market sometime in 2012. It will be interesting to see how late to the game AMD is in this arena and if they can compete with what ARM is doing or even what Intel will be doing with Medfield.

Popular enthusiast motherboard maker MSI, today officially launched a new line of motherboards supporting AMD’s 9-Series chipsets. Specifically, the 990FXA-GD80 and the 990FXA-GD65 motherboards bring support for AMDs latest native eight-core AM3+ processors. The high-end motherboard, the 990FXA-GD80, comes equipped with MSI’s OC Genie II overclocking technology as well as “Military Class II components with MIL-STD-810G Certification.”
Further, the new 9-series lineup features support for both NVIDIA SLI and AMD CrossFireX multi-GPU technology, USB 3.0, native SATA III 6Gb/s, and THX TruStudio PRO surround sound.

Cray has been a huge name in the supercomputer market for years, and with the new XK6 they are promising to deliver a supercomputer capable of 50 Thousand Trillion operations per second. Powered by AMD Operton CPUs and NVIDIA GPUs, each XK6 blade is comprised of 2 Gemini interconnects pairing four AMD Opteron CPUs with four NVIDIA Tesla X2090 embedded graphics cards. The graphics cards in each blade have access to 6GB of GDDR5 memory, and are connected via PCI-E 2.0 links to the Opteron processors. The CPUS have access to four DDR3 memory slots “running at 1.6GHz for every G34 socket,” according to The Register. This amounts to 32GB per two-socket node when using 4GB sticks.
Cray plans to wait until AMD releases the 16 core 32nm Opteron CPUs in Q3, dubbed the Opteron 6200s. The Register quotes AMD’s CEO Thomas Siefert as promising the processors are based on the new Bulldozer cores (and would be compatible with the current G34 sockets) “would ship by summer.”
Further, they claim that Cray’s goal with the XK6 was to keep the new blades within the same thermal boundaries as its predecessor, despite the inclusion of GPUs into the mix. Cray has indicated that, due to their success in remaining within the thermal envelope, their customers will be able to use XE6 and XK6 blades interchangeably and will allow them to customize their supercomputer load-out to meet the demands of their specific computing workloads.
Each cabinet is capable of storing up to 24 blades, and can deliver up to 50 kilowatts of power. Each of the Tesla X2090 GPUS are capable of 665 gigaflops during double-precision floating point operations, something that GPUs excel at. As each XK6 blade contains 4 GPUS, and each cabinet can hold 24 blades, customers are looking at 63.8 teraflops of computing power solely from the graphics cards. On the CPU side of things, Cray is not able to release specifications on the processors as AMD has yet to deliver the chips in question. The Register estimates that each XK6 blade will provide 3.5 teraflops of floating point computing power, which amounts to approximately 84 teraflops per cabinet.
With a claimed capability to utilize up to 300 cabinets full of XK6 blades, customers are looking at approximately 44 petaflops of computing horsepower, with GPUs delivering 19.14 petaflops, and the CPUs estimated to provide 25.2 petaflops of floating point computational power.
The first customer of this system will be the Swiss National Supercomputing Centre. According to the Seattle Times, the center’s director Professor Thomas Schulthess stated that they chose the Cray XK6 based supercomputer not for it’s raw performance, but because “the Cray XK6 promises to be the first general-purpose supercomputer based on GPU technology, and we are very much looking forward to exploring its performance and productivity on real applications relevant to our scientists.”

We now know what to expect from AMD's Llano, as far as pricing and initial model numbers. None of the Llano chips top $200 which is good as the Intel models that they will be competing against are also in that price range. Bulldozer is a little more expensive, with the lower end quad-core running $220 up to $320 for the high end octo-core, again bang on with Intel's competing Sandy Bridge parts. It is a question of the performance gap between Intel and AMD, which unfortunately remains unanswered for now.
"AMD has started shipping its Llano APUs to notebook clients and will begin to market the APUs to channels in July 2011, according to sources from notebook makers.
AMD targets to ship one million notebook-use Llano APUs in June, 1.5 million in July, and a total of 8-9 million for the whole of 2011, revealed the sources, citing AMD's internal estimates.
If the shipment goals are realized, AMD will be able to boost its share in the notebook CPU segment to 15% by the end of the year, the sources commented."
