In this article we present the new server architecture based on AMD's Bulldozer core class. We describe the 4200 series CPUs for 1 and 2-socket systems and 6200 series for 2 and 4-socket systems and a maximum of 64 cores.

Comparison with INTEL
In the greater volume market segment, the new generation AMD Opteron achieved an 89% performance increase in the SPEC tests, at the same CPU cost (Xeon E5640, against Opteron 6276).
With the same system cost, however, offers 25% more CPU power, more memory and better hard drive specs.
Regarding virtualization, it requires the greatest amount of core, addressable memory, L3 cache and the least consumption. The AMD solutions provide a cost-per-VM up to 77% less and allow you to have a 2.6 times higher number of VMs per rack.
The cloud requires the maximum density, made possible by low power consumption: 5.3W/core for 6200 Series, 4.375W/core for 4200 Series against 10W/core for the best Intel CPU. In addition, the top of the range AMD (6282 SE) gets 25% more in web-based benchmarks, compared to Intel competitor (Xeon 5690).
Finally, for the HPC is required scalable performance, high-performance computing, high memory bandwidth, many core and SIMD extensions for numerical computation. AMD gets 73% more memory bandwidth than Intel, has a larger number of cores per rack, a greater number of FLOP per rack and up to 80% less cost. To get the raw power of a rack of 16-core AMD CPUs, you need two full racks of Intel CPUs.
