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.
Highlights
- Quad-core Xeon processor handles parallel workloads
- 12 MB L2 cache reduces memory latency
- 45 nm process keeps power draw to 80 W
- LGA 771 socket fits compatible server boards

Questions about this item
How much heat does the 80 W Xeon E5420 generate when running continuously?
The processor has an 80 W thermal design power, so sustained full-load operation will dissipate up to 80 watts of heat into the chassis.
Which socket and front-side bus must the motherboard provide for this Xeon E5420?
It requires an LGA771 socket and a 1333 MHz front-side bus to function.
