AMD Phenom II X4 840

Cores4More cores means more threads and therefore more processes can be run simultaneously
Speed3.2GHzClock frequency indicates processor speed, but is only reliable in comparisons between CPUs of the same family
CodenamePropusThe code name given by the manufacturers
Release Date04 Jan 2011 The more recent the release, the more likely the CPU will receive up-to-date manufacturer support
TDP95WThe 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 Cache2048KBAfter 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 SocketSocket AM3The motherboard socket and CPU socket should match to indicate the CPU is compatible with the motherboard and will fit into it

Phenom II X4 840 compatibility review

Overall, the AMD Phenom II X4 840 has exceptional performance. Its 4 cores clocked at 3.2 GHz provide swift processing speeds and allow multiple processes to be run simultaneously.

The CPU is now over 10 years old, which means it is extremely out of date and is based on very aged technologies.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 45 nanometers, the Phenom II X4 840 is not efficient at all by modern standards, and with a Thermal Design Power of 95W the amount of power necessary to run it does not make up for the inefficiency of its physical structure.
