Pros: Overclocking

Cons: Performance overlap with prior generation

Okay, This processor gets a lot of hate from all sides due to the stigma surrounding the BullDozer architecture. I upgraded from an A64 X2 6000+, and it is much faster than my previous system. It feels faster than my old Phenom 9950 @ 3.2ghz by a good margin as well.

Games play nicely on it, mainly due to the ludicrous overclocking (4.8 Ghz). I have a 3DMark 2011 score of P5251 (GTX 470) with a physics score of 4581.

Skyrim runs smoothly with all settings manually set to Ultra.
Crysis 2 maintains about 30fps on DX11 ultra (V-Sync on, more than likely due to lack of videocard muscle)
Far Cry 2 holds at 60fps (V-Sync)

Haven't got to test with Rage or Metro 2033 yet, will update when I get them installed and tested.


Thanks for this review. I'm waiting for my 4100 to arrive, and while my upgrade isn't going to be as much as yours - going from a phenom II 965, c3 - it's good to know it has no problems with Skyrim, another thing I ordered and am waiting for..
Im not certain its going to be much of an upgrade at all from a C3 phenom, as those seem to OC nicely. Some things will be faster, some might actually get slower. Keep in mind that the FX-4100 seems to land around a Phenom II 3.2Ghz performance wise at stock clocks.

Granted, it usually overclocks by at least 800Mhz-1Ghz. At 4.6Ghz expect performance in the same ballpark as a Phenom II @ 3.8-4Ghz. You need 4.8Ghz to get any benefit vs a tweaked Phenom II C3 system, and 4.8 is not always possible to attain. I only push my cpu to 4.8Ghz for benchmarking etc, my 24/7 settings are around 4.7Ghz. This is mainly due to my chip not being 100% stable without 1.6v(borderline too high) at 4.8, but about 1.5v is fine for 4.7.
I know it wont be much of an upgrade, if any at all.
Like I mentioned in thhe Bulldozer thread: I've got an am3+ board and I'm not affraid to use it!
Originally I was planning on waiting for the B3 steppings, or even Piledriver, but seeing the FX 4100 being dirt cheap as it is + I may be able to sell my Phenom for €80 to someone upgrading from a Pentium 4 it's a good deal: €30 in effect for a new toy.
Thanks for your info on your oc experience with the chip. I can't wait to play with mine!
