Opteron 175 at 3.1ghz on stock vcore with stock HSF

Very Impressive  

Wonder how much higher it would go with some better cooling and more voltage.

DFI lanparty expert is what i have. very nice ocer. Tho just about any thing out of dfi will oc that puppy nice. If i rember that stepping has seen the highest oc's out of all the optys. One other thing dont nock that stock cooler only the best ones seem to out do that one.

No I find it very impressive but I am an IEEE certified engineer and not an ignorant fanboi and if you run a benchmark like Himemo http://accc.riken.jp/E/HPC_e/HimenoBMT_e/index_e.html it will blow any Intel system ever made away because the opteron has six complex instruction decoders vs only two for the Intel. The 6 simple decoders on core 2 are useless since the packet lsizes are greater than 2mb. http://www.hpcwire.com/hpc/658628.html The Cray has 960 180's and the Fujitsu had 2048 3.73 Dempseys. Based on Thunderbird at Sandia Core 2's would not cut the margin at all.. Thunderbird does 53 teraflps vs 101teraflps. for Red Storm using the same 2.2 MW of power. In two of the key benchmarks Red Storm beat Blue Gene L using 130nm opteron 146's. It was upgraded this summer to 185's. http://www.physorg.com/news62939660.html

In benchmarks Solid Works is where the AMD begins to consistently beat Core 2, Move to medical imaging like MRI's single core Opterons will beat Core 2 because they have 3 complex decoders vs only two for core 2. The simple decoders don't carry ny significant loads because the data goes beyond the 48 bits they can see. When you get into big science where everything is 64 bit even the Dempsey beats Core 2 hands down. It has two complex decoders per core vs only one for Core 2 (core 2 has two cores per cpu so I refer to it as having 2 complex decoders per chip). If you look at the DARPA benchmarks http://icl.cs.utk.edu/hpcc/ You will find all thetop raanked computers are either IBM or AMD. Watson and ASCI Purple would drop out of todays rankings as both RedStorm and Jaguar have been upgraded to 185 Denmarks since the Benchmarks were posted. By the end of March Jaguar will be getting close to 200 teraflops and pass Blue Gene L in every benchmark except HPL(linpack) http://www.hpcwire.com/hpc/724626.html

Given the Core 2 scalablity problems 1 Petaflop as Jaguar will do when finished using 939 opterons simple won't be feasible since the power requirements are more than twice the XT3. That is why DARPA/DOE/NSF bought 10 compuiters with opterons two with IBM P5/7 and no Intel based designs for FY2007.

a benchmark like Himemo
