AMD Barcelona vs. Shanghai for SAP
Volker Wetter pointed me in his blog entry at SAPonSun to an interesting fact. You already know the stuff about the comparision between the 8-socket systems of HP and Sun because i wrote about it last year (here and here). But Volker points to the results of two 4600M2 with different processor generations at the end of his article.
The benchmarks for the certifications 2008061 and 2008070 test two identical systems with one exception: The first one is a AMD Opteron “Barcelona” (Quad-Core AMD Opteron Processor 8360 SE, 2.5 GHz, 128 KB L1 cache and 512 KB L2 cache per core, 2 MB L3 cache per processor) and the second benchmark was executed on an AMD Opteron “Shanghai” (AMD Opteron Processor 8384, 2.7 GHz, 128 KB L1 cache and 512 KB L2 cache per core, 6 MB L3 cache per processor). The Barcelona-based system was able to yield 29,670 SAPS, the Shanghai-based system was measured with 39,270 SAPS. At 108% the clock rate the new processor generation was able reach a 132,3 percent higher benchmarking result. It´s safe to say, that Shanghai is a major step forward. I´m glad about this development as i´m the Account SE of Sun for AMD in Dresden. So i know many people of AMD Dresden IT in person. News get faces when you do customer visits on a regular schedule.
