AMD Athlon II X4 638

Cores4More cores means more threads and therefore more processes can be run simultaneously
Speed2.7GHzClock frequency indicates processor speed, but is only reliable in comparisons between CPUs of the same family
CodenameLlanoThe code name given by the manufacturers
Release Date01 Feb 2012 The more recent the release, the more likely the CPU will receive up-to-date manufacturer support
TDP65WThe 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 Cache512KBThe 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 Cache4096KBAfter L1 cache, L2 is utilized for slower (but still very fast) data access
Lithography32nmThe smaller the lithographic technology used, the less power is required to run the CPU, and the less heat is created during intense use
CPU SocketSocket FM1The 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

Athlon II X4 638 compatibility review

Overall, the AMD Athlon II X4 638 has exceptional performance. Its 4 cores clocked at 2.7 GHz provide competent processing speeds and allow multiple processes to be run simultaneously.

The CPU is now over 7 years old, which means it is extremely out of date and is based on very aged technologies.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 AMD.

Created with lithographic technology sized at 32 nanometers, the Athlon II X4 638 is quite efficiently built, and with a Thermal Design Power of 65W the amount of power necessary to run is not excessive.
