Here are some more information for Opteron Cpu:

Gpu And The Cpu Battle

TOP500.org announced the 34th Annual Global Top 500 supercomputers list. As a twice-yearly gathering of the world's supercomputers, the focus of both parties gathered here, maybe you do not care about IT, do not care about technology, but you must be concerned about their own lives, then no matter from research or from the defense is concerned, supercomputer DELL INSPIRON 6000 Battery You need to know some.

I Like many people, for the second ranking in 2009 put a great deal of attention, although in May this year when the first TOP500 chart, a lot of super-computers seating has been set, but in the near future are circulating a Fangjian people look forward to the news - China's first petaflop supercomputer system, "Milky Way I" was successfully developed, which is China's continued after the United States, the world's second able to develop a petaflop supercomputer country. And let it successfully entered the TOP500 supercomputer the top five is not what we always believed that huge CPU combination, but thanks to the advanced GPGPU programs. This is indeed shocking!

The industry has been in dispute since the PC's future is GPU or CPU, or the "CPU + GPU", the parties have different views. So, in the end, "Milky Way One" is a DELL LATITUDE D610 SERIES Battery of how to use the GPU into the top five it?

Learned that the "Milky Way One" in 6144 has a processor, can provide 200 trillion times the computing performance, but as a petaflop supercomputer, this result appears to be some unworthy of the name. In fact, "Milky Way on the 1st," the most critical part is using 5120 AMD HD4870 graphics card, GPU calculations are not as good as the breadth of CPU, but as long as environmentally appropriate, GPU will show far exceeds the CPU's computing power, which in the "Milky Way 1 number "has been confirmed. 5120 AMD HD4870 graphics cards to help, "Milky Way One" supercomputer reached a peak performance of 1.206PFlops, Linpack test performance of more than 0.5603PFlops, can be said that AMD's GPU as "Milky Way One" contributed more than 80% of the computing performance.

In the TOP500 list in recent years by virtue of PowerXCell + AMD Opteron processors, the combination has been to occupy top position in IBM "Roadrunner" (Roadrunner) out of a super computer for the top position, "Jaguar" (Jaguar) to the 1.759PFlops Instead, boarded the top results, while its peak performance is reached 2.331PFlops. The IBM "Roadrunner" (Roadrunner) supercomputer Zeyi 4% of the performance gap fell second.

In this six-month period, Cray built "Jaguar" (Jaguar) performance on the surge by 70% in the original equipment, the basis for such a huge performance photogenic get the secret lies in AMD released in June this year, "Istanbul" 6-core Opteron processors. Equipped with AMD released six-core "Istanbul" Opteron 2435 processor (clocked at 2.6GHz, a single, floating point performance 10.4GFlops) after, "Jaguar" (Jaguar) core number from 129.6 thousand to 224,162 (core increase the number of 73%), and each core with 2GB of memory, each complete set of computing nodes from 12 processing cores and 16GB of shared memory component, the entire system has 300TB of DELL INSPIRON 8600 laptop battery, 10PB (10000TB) hard drives.

In fact, for Cray concerned, such a result has long been expected. In June of this year's six-core AMD Opteron processors, released at the same time, Cray, and Oak Ridge would mean that that test, they did not "Jaguar" (Jaguar) and computing power wasted in Linpack, but on the rapid into the actual scientific applications. Because at that time even if the "Jaguar" (Jaguar) to go beyond IBM's "Roadrunner" (Roadrunner), advantage is not obvious, might as well wait for half a year to the world a big surprise. It seems Cray, and Oak Ridge was already ready to use 6-core AMD Opteron processors bring the world a pleasant surprise.

In this super-computer 500 Ranking in the top five of the system has four were to rely on AMD to provide a record of performance, which also includes the recently upgraded Cray XT5 system "Kraken", we can see that AMD in the super-operator in the field of upper status is still strong. In the first quarter of next year, AMD also will provide HPC customers with the world's first 8-core and 12-core x86 Opteron processors, double the computing density and multi-performance processing capability, four-channel DDR3 memory with the new AMD-P 2.0, and AMD -V 2.0 TOSHIBA PA3383U-1BRS laptop battery will make it doubly look forward to.

Through "Milky Way One" of the GPGPU program, AMD's leading ATI Stream technology had unfolded in front of the world, which for the future GPGPU programs and a substantial increase in HPC performance has provided an opportunity. "Milky Way One" and not rely mainly on CPU with GPU into the supercomputer TOP500, is sufficient for the GPU and the CPU will lead the PC debate the future of painting a full stop. The future, perhaps an AMD-based processor and AMD GPU's PC, will allow you to experience HPC computing and ultra-high-speed visual experience. I think this era has left us far away.

what's the difference between a socket 939 opteron and a socket 939 athlon 64 cpu?

Opterons typically have more cache and will perform slightly better than a similar speed Athlon 64. They were released on the socket 939 interface, though they were originally made for the socket 940.

The main difference is that the 939 doesn't require registered (buffered) DIMMs like the 940 Opterons do.
