Intel Xeon E5420 2.5 GHz 12 MB L2 1333 MHz FSB LGA771 45 nm 80 W switch module

Intel Xeon E5420 2.5 GHz quad-core processor

The Intel Xeon E5420 is a 2.5 GHz quad-core processor built on a 45 nm node with 12 MB L2 cache and a 1333 MHz front-side bus. It fits the LGA771 socket and carries an 80 W thermal design power. This module suits servers and workstations that need four cores of Intel Xeon performance in a legacy platform.

Sustained-load behaviour for 80 W TDP

Under continuous load the 80 W TDP means the cooling solution must dissipate that heat steadily, not just in short bursts. The 45 nm process and 12 MB L2 cache help maintain throughput during long compute tasks. Buyers who need higher core counts or a newer socket should look elsewhere.
