Intel Xeon E7220 socket: Socket 604

What the Xeon E7220 is

The Intel Xeon E7220 is a 2.933 GHz multiprocessor dual core from September 2007. It runs two Core cores at 2.933 GHz with no turbo, so 2 cores give 2 threads. Cache is 8 MB of L2 as two 4 MB dies on a 65 nm process. Power is rated at 80 W on Socket 604.

The E7220 topped the Tigerton dual core line on a 1066 MT/s bus with an 11x multiplier at about 1177 dollars launch price. It exists because multiprocessor buyers wanted the highest dual core clock at the same 80 W as the E7210.

Socket and motherboard compatibility

The E7220 fits Socket 604 multiprocessor server boards with a BIOS that lists Tigerton dual cores. It suits quad-processor chassis qualified for 80 W parts.

Memory, PCIe and cooling

Memory is DDR2 through the server board chipset.

A 1066 MT/s front side bus ties the CPU to the server chipset. PCIe slots hang off the chipset.

Cooling uses vendor qualified server heatsinks for the 80 W envelope in multiprocessor chassis with directed airflow.

Upgrade paths

On Socket 604 the upgrade is quad Tigerton such as the Intel Xeon E7340 at 2.4 GHz with 8 MB of cache, or the Intel Xeon E7210 at 2.4 GHz for a lower cost dual core. Beyond Socket 604 a move to a newer Xeon platform needs new boards and memory.
