3Based on STREAM benchmark results obtained by AMD Performance Labs as of October 2011. 73 GB/s: 2 x AMD Opteron™ processors Model 6276 in Supermicro H8DGT, 64GB (8 x 8GB DDR3-1600) memory, SuSE Linux® Enterprise Server 11 SP1 64-bit, x86 Open64 4.2.5-1 Compiler Suite. 42 GB/s: 2 x Intel Xeon processors Model X5670 in Supermicro X8DTT server, 24GB (6 x 4GB DDR3-1333) memory, SuSE Linux® Enterprise Server 11 SP1 64-bit, Intel Compiler v11.1.064.
4As of Nov 14, 2011, AMD Opteron™ processor Models 4200 EE have the lowest known power per core of any x86 server processor, at 35W TDP (35W/8 = 4.375W/core). Intel's lowest power per core server processor, L5630, is 40W TDP (40W/4 = 10W/core). See
http://ark.intel.com/products/series/47915. Previous record held by AMD Opteron processor Models 4100 EE at 35W TDP / 6 cores = 5.83 W/core.
5VMs/rack (2P and 4P) One rack of AMD Opteron 6200 Series-based servers can support 672 VMs (1 VM per core, 2U servers). This would take three racks of floor space and 56 2U Intel Xeon 5600 Series-based servers to do the same. Assumes 1 VM/core, AMD Opteron 6200 Series-based 2P 2U server has up to 32 cores, supports up to 32 VMs/server x 21 servers per rack, which equals 672 VMs per server. Intel Xeon 5600 Series-based 2P 2U server has up to 12 cores, supports up to 12 VMs/server x 21 servers per rack, which equals 252 VMs per rack, Intel specs as of 11/4/11 at

6Top bin comparisons. Dell R710 with two top bin Intel Xeon processor Model X5690s is $7,103. Since pricing for a Dell R715 with two top bin AMD Opteron processor Model 6282 SE (1ku $1019) is not yet available, the similarly priced AMD Opteron processor Model 6140 (1ku $989) was used and the server yielded a price of $4564. That is a 36% price savings. Both servers were configured with 32GB RAM, 146GB 10K hdd, and 3yr base warranty and large enterprise pricing is from www.dell.com as of 10/22/11. HP DL 580 with four top bin Intel Xeon processor Model E7-4870 is $29,336 at www.dell.com. Since pricing for an HP DL585 pricing with four top bin AMD Opteron Model 6828 SE (1ku $1019) is not yet available, the similarly priced AMD Opteron processor Model 6140 (1ku $989) was used and server yielded a price of $11,094. That is a 62% price savings. Both servers were configured with 64GB RAM, 72GB 15K hdd, and 3yr base warranty and large enterprise pricing is from www.hp.com as of 10/22/11. VMware vSphere pricing not included, assuming both servers configured with versions 5.0 or 4.1u2, which are the same price for AMD- and Intel-based servers.
