Phenom X3 Models

The Phenom CPU with three cores is called "Phenom X3" and on the table below we list all models available. Models based on the "B2" revision (i.e. CPUs with model number ending in "00") have a bug called "TLB bug", which is fully described here. Models based on B3 revision (i.e. CPUs with model number ending in "50") don't suffer from this problem.

* MC stands for “Memory Controller”. This clock is also known as "North Bridge Clock" or simply "NB Clock".

TDP, Thermal Design Power, is how much power the CPU dissipates, meaning that you must match the CPU with a cooler capable of dissipating that amount of power
