With the 6100 launch, AMD's battle with Intel for the high-end x86 server market enters a new era. In the two-socket server space, Intel's Westmere EP retains the speed title, clock-frequency-wise. At the same time, Nehalem EX, due to be announced tomorrow, will give Intel exclusive ownership of the 8P-and-above x86 server market. Meanwhile, AMD will use Magny-Cours to try to outmaneuver Intel with better price-performance and performance-per-watt on two-socket and four-socket machines.
While Intel can still deliver faster cores on its Westmere EP, thanks in part to its 32nm process technology, AMD, with its 45nm technology, has opted to go for more cores that run proportionally slower. The fastest Westmere EP CPUs top out at 3.33 GHz for the 6-core version and 3.46 GHz for the 4-core version. In contrast, the speediest 12-core and 8-core Magny-Cours come in at 2.3 GHz and 2.4 GHz respectively.
The $266 to $1,386 price spread for Magny-Cours will look especially attractive for large-scale 4P setups compared to the more expensive Nehalem EX. (As of Monday, prices on the EX series have not been announced, but are expected to range between $800 to $3,600.) For HPC deployments in particular, where hundreds or thousands of nodes are involved, the up-front cost savings are likely to be significant.
