AMD promises to introduce its new quad-core processors with K10 micro-architecture in the end of August – beginning of September this year. The first processors on this new micro-architecture will be server Opteron chips based on a core codenamed Barcelona. Unfortunately, AMD engineers failed to hit mass production quantities with the current revision of high-frequency chips. Looks like the main obstacle on the way to higher working frequencies was the fact that four cores running at high speed consume much more power than the platform TDP actually allows. With every new revision and transition to finer production technologies the power consumption will keep lowering and the working frequencies will keep growing. So far, AMD has to immediately start selling processors in order to improve its financial situation, so the first one to start selling will be the quad-core server processor model working at 2.0GHz.
