AMD Athlon 64 1640B

Cores1More 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
CodenameLimaThe code name given by the manufacturers
Release Date19 Oct 2004 The more recent the release, the more likely the CPU will receive up-to-date manufacturer support
TDP45WThe 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 Cache128KBThe 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 Cache512KBAfter L1 cache, L2 is utilized for slower (but still very fast) data access
Lithography65nmThe 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 939The 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 64 1640B compatibility review

Overall, the AMD Athlon 64 1640B has average performance. Its 1 core clocked at 2.7 GHz provides competent processing speeds but with only a single core, it will never match up to modern competitors.

The CPU is now over 16 years old, which means it is extremely out of date and is based on very aged technologies.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 65 nanometers, the Athlon 64 1640B is not efficient at all by modern standards, although with a Thermal Design Power of 45W it does not require very much power to run.
