Final words: AMD Shanghai rumors
We heard through the grapevine that AMD's Shanghai has already been benchmarked by a few OEM related people. Those people were very pleased with its performance; the improved IPC and 6 MB L3-cache are probably paying off. Despite the very bad and late start, there was quite a bit of enthusiasm for AMD's Barcelona CPU. Supermicro's and Tyan's fastest blade servers are based on the latest AMD chip for example. The AMD Barcelona seems to have stolen a bit of the quad-socket market share of the Intel Tigerton CPU, which was a lot harder to spot at CeBIT.
