Server CPUs overview

As the CPU is still one of the most important cost factors in a server, we want to give an overview of the currently available server CPUs. We'll start with the Intel CPUs.
The biggest advantage of Intel's newest Bensley platform is the longevity: the Dempsey, Woodcrest, and quad core Clovertown Xeon all use the same socket and "Bensley" platform. Even the successor of Clovertown, the 45nm Harpertown, is confirmed to be compatible with the Bensley platform.

The Opteron CPU comes in two forms: one for DDR and one for DDR-2. The DDR-2 version uses 4 model numbers, the DDR version three.

The Opteron's TDP numbers are the maximum power consumption numbers, while Intel's numbers are "thermal solution design targets". In practice, this means that you should subtract about 5% from AMD's TDP numbers to compare the two brands. AMD is not doing too well in the dual CPU arena: it needs about 30W more power per dual core CPU and CPU clock speed has hardly increased the past two years. Luckily for AMD, the power disadvantage is negated by the use of FB-DIMMs instead of DDR2 on the Intel platform.
