Cores4More cores means more threads and therefore more processes can be run simultaneously
Speed2.5GHzClock frequency indicates processor speed, but is only reliable in comparisons between CPUs of the same family
CodenameHarpertownThe code name given by the manufacturers
Release Date25 Mar 2008 The more recent the release, the more likely the CPU will receive up-to-date manufacturer support
TDP50WThe lower the TDP, the less power the CPU requires to run and thus the more efficient it is and the less heat it creates
L1 Cache256KBThe bigger the L1 cache, the more data can be stored for lightning CPU access to priority processes (though a bigger cache means a higher latency
L2 Cache12288KBAfter L1 cache, L2 is utilized for slower (but still very fast) data access
Lithography45nmThe smaller the lithographic technology used, the less power is required to run the CPU, and the less heat is created during intense use
CPU SocketLGA 771/Socket JThe motherboard socket and CPU socket should match to indicate the CPU is compatible with the motherboard and will fit into it
Unlocked MultipliernoAn unlocked clock multiplier means you can adjust the multiplier for an overclocking speed boost

Xeon Processor L5420 compatibility review

Overall, the Intel Xeon Processor L5420 has very good performance. Its 4 cores clocked at 2.5 GHz provide mediocre processing speeds but allow multiple processes to be run simultaneously.

The CPU is now over 11 years old, which means it is extremely out of date and is based on very aged technologies. This processor will be dwarfed in performance by its modern counterparts, and will likely have very little support from Intel.

Created with lithographic technology sized at 45 nanometers, the Xeon Processor L5420 is not efficient at all by modern standards, although with a Thermal Design Power of 50W it does not require very much power to run.
