There is a sub-culture in the computing world that is more or less analogous to the world of NHRA drag racing: liquid nitrogen overclocking. And if you are really serious, liquid helium. During a press event in Austin, TX in August to discuss the upcoming Bulldozer processor, a team of overclockers pushed the new architecture to frequencies well beyond safety and well beyond where they should be. Without giving away the whole story yet, AMD was able to set a new frequency world record...
Sami Mäkinen and his team hit 8.429GHz on liquid nitrogen and liquid helium with a near-production FX processor sample. This bests the reigning record of 8.308 GHz that was hit on a Celeron processor with LN2.
On August 31, an AMD FX processor achieved a frequency of 8.429GHz, a stunning result for a modern, multi-core processor. The record was achieved with several days of preparation and an amazing and inspired run in front of world renowned technology press in Austin, Texas. This frequency bests the prior record of 8.309GHz, and completely blows away any modern desktop processor. Based on our overclocking tests, the AMD FX CPU is a clock eating monster, temporarily able to withstand extreme conditions to achieve amazing speed. Even with more conservative methods, the AMD FX processors, with multiplier unlocked throughout the range, appear to scale with cold. We achieved clock frequencies well above 5GHz using only air or sub-$100 water cooling solutions.
I was in attendance for the event and have to say that group put on a spectacular show and anytime you can play with liquid helium running at near absolute zero temperature, it's worth paying attention! In fact, I put together a video of the event that you can see below and if you haven't participated or seen something of this nature, it is worth checking out!!
Now I need to temper some dreams right now - the chances of you or I reaching these types of clock speeds on the Bulldozer CPUs upon release are pretty close to nil. What was more interesting was the casual overclocking we saw pushing upwards of 4.8+ GHz without breaking a sweat and that is what we will be investigating with our review of the processor later this year.
Update: Here is the screenshot from the official HWBot frequency rankings as well as a different video created by AMD themselves summarizing the event.
Introduction and Specifications

ECS developed the HDC-I motherboard to take advantage of AMD's new Brazos platform that's based on the Hudson M1 chipset and their latest E-350 dual-core processor and integrated DDR3 800/1066 memory controller. The dual-core E-350 APU, which combines the CPU and GPU, brings a host of features to mini ITX enthusiasts like USB 3.0 compability, SATA 6Gb/s support, bluetooth and Radeon HD 6310 graphics and UVD 3 to play 3D Blu-ray and HD-1080P movies.

Another huge advantage of going with a mini ITX motherboard for your next home theater PC is the balance of computing power and power consumption that the AMD Brazos platform adds to the ECS HDC-I. The HDC-I is an energy-efficient motherboard that has integrated computing power and graphics firepower for users looking for an "all-in-one" solution for their next small form factor build.
Bulldozer Ships for Revenue
Some months back we covered the news that AMD had released its first revenue shipments of Llano. This was a big deal back then, as it was the first 32 nm based product from AMD, and one which could help AMD achieve power and performance parity with Intel in a number of platforms. Llano has gone on to be a decent seller for AMD, and it has had a positive effect on AMD’s marketshare in laptops. Where once AMD was a distant second in overall terms of power and performance in the mobile environment, Llano now allows them to get close to the CPU performance of the Intel processors, achieve much greater performance in graphics workloads, and has matched Intel in overall power consumption.

Some five months later we are now making the same type of announcement for AMD and their first revenue shipment of the Bulldozer core. The first chips off the line are actually “Interlagos” chips; basically server processors that feature upwards of 16 cores (8 modules, each module containing two integer units and then the shared 256 bit FPU/SSE SIMD unit). The first customer is Cray, purveyor of fine supercomputers everywhere. They will be integrating these new chips into their Cray XE6 supercomputers, which have been purchased by a handful of governmental and education entities around the world.

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.
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.

AMD is showing off their stuff down in Texas right now and there are reports of what is being shown off slowly appearing. First to the plate is SemiAccurate with a slide detailing the next generation of Bulldozer as well as a new variant called Piledriver. The new Orochi Bulldozers are said to offer a 35% increase in the performance of server tasks and many techs will be glad to hear it is a drop in upgrade, no hours of reconfiguration needed.
The enthusiast will be more interested in Piledriver which is a renovated Bulldozer core, finessing the existing architecture to squeeze half again as many gigaflops out of Comal and Virgo when compared to Llano. They've also included the HD7000 family, aka the Southern Islands family of GPUs into the announcement as well. We know that the new generation of APUs are well ahead of schedule and we can hope that the GPU side has also at least kept up with expectations if the scarcity of the HD6950 and HD6970 mean what we hope it means. Drop by for the specs on the GPUs and more at SemiAccurate.
"It looks like Trinity, aka the next generation big APU, is going to be everything the rumors suggest. At Global Foundries GTC conference today, they foundry confirmed many of the rumors that are floating."

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.
"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!"

Tagged: tape out, GLOBALFOUNDRIES, amd, 20nm
When then discussion turns to a chip taping out, we are referring to an obsolete practice where a chip would be designed on a large scale and then reduced through photolithography. Originally, once a chip design was finalized on paper it went to the artwork stage where an engineer would literally tape out and glue the design to create a photomask which would allow light through in a variety of ways or utterly block it. That light was focused to create a smaller version, which then was used to make an even smaller version ... until it was of a size to etch the physical components of the chip onto the wafer and with a bit of luck and a lot of skill you would end up with a chip that worked to the specs you expected.
You can't exactly do that anymore, as the current generation of chips coming out of GLOBALFOUNDRIES uses a 20nm process, smaller than even extreme UV wavelengths and the magnitude of size reduction would be insurmountable. Thankfully there is CAD and many other more mature ways of creating chips than the old cut and paste method. This puts AMD in a good position to transfer to a 20nm process in the future, smaller than Intel's 22nm process but lacking the Tri-Gate three dimensional transistors that Intel will be implementing. Drop by The Inquirer for more.
"CHIPSHOP Globalfoundaries has announced that it taped out a test chip using its 20nm process node.
Globalfoundaries, best known for being the main chip fab partner of AMD, has been working to get its 28nm and 20nm process nodes up and running. For Globalfoundaries and its customers - in particular, AMD - having a mature 20nm process is desirable to show it has possibilities for die-shrinkage in the near future."
