AMD has been working on its processor technology and has just launched its Opteron 6200 and 4200 Series processors. The Opteron 6200 series features 16 cores which is really eight dual core units and four memory channels. The Opteron 4200 features eight cores, or four dual core units, and two memory channels. The 16 core processor packs the largest number of cores available on x86 chips today. The processors are based on AMD's new chip design called Bulldozer, which provides performance improvements while saving on power. The Bulldozer architecture mixes the CPU with integer units and a shared floating point unit so more operations can be executed per clock cycle while drawing lower power.
The new processors offer optimized scalability for virtualization with up to 73% more memory bandwidth and up to 24% to 84% better performance on key cloud, virtualization and HPC workloads making them ideal for virtualization of servers. They also provide more efficient economics for the cloud with half the power per core, requiring 2/3 less floor space and up to 2/3 lower platform price. The chips are shipping now and will be available in servers from HP, Dell, Cray and Acer soon.
