he Athlon II X4 series is an excellent low cost alternative to its big brother, the Phenom II X4. I have run several tests and compiled the results in a comparative format.
The Athlon II X4 series is an excellent low cost alternative to its big brother, the Phenom II X4. I have run several tests and compiled the results in a comparative format. The Athlon II shows some weakness – about -25% averaged in a heavy multitasking environment as compared to the Phenom II, but is within .25% in a non-multitasking situation. For general purpose and gaming oriented computing it is hard to beat, fairly cool running and not the power hog many think it is.
A WARNING: BIOS, BIOS, BIOS!!! Do not assume you need to update, and if you do be prepared to revert. When I first installed this CPU I did not update my bios and I had full functionality except for the core temp sensors reading -254. I decided to update and lost the ability to clock past 3.4 and also the ability to lower the NB multiplier (that bios rev. for some reason is no longer available for download). Many BIOS resets and even a processor swap or two may be necessary to get where you want (you could also get a low clocking CPU and then it is a futile battle). Remember this!! Some modern BIOS actually reduce functionality. This was only a warning not a suggestion. I bear no responsibility if you have a problem; this was a kind of public service announcement.
