The TDP of the FX-8150 is the same 125 W as the most recent Phenoms we've reviewed and indeed also the
stock power consumption is in line with the earlier models. Under load the consumption is 17 W higher than the
1100T's, but it's worth keeping in mind that also the motherboard is different, which partly explains the
difference. Another thing to notice is that to test for the "worst case scenario" the cool'n'quiet and other
power saving features were switched off. With those enabled the idle load dropped to 92 watts.
Overclocking, on the other hand, made the power consumption really shoot through the roof, at 1,4125 V core
voltage the system drew 433 watts from the grid.
Performance in highly threaded programs
Single core performance
This is the first time we've had the chance to put the new architecture to test and unfortunately it turned
out to be a bit of a let-down. In multi-threaded applications the performance is good, and the chip does
overclock very nicely, but for average gamer and home user majority of programs just aren't going to make
proper use of all the cores. In single-threaded programs and even some multi-threaded ones the FX-8150 can't
even beat the i7-870, which already represents Intel's old range of CPUs. If near future brings better
threading into more programs, the Bulldozer may still gain performance in comparison to Intel's offerings, but
"if", "maybe" and "in the future" just don't sound too good for AMD considering they've already had some
catching up to do.
Cost-wise the situation isn't too bad, and if you already have a motherboard that supports the new chips,
it may be a viable upgrade. Anyway for not too much more you can also get the superb i7 2600K. Overall then
the FX-8150 isn't so much a "bad" chip, it's just been delayed way too often and in comparison to what Intel
has to offer in similar price range, it just doesn't make much sense if you aren't specifically demanding the
8-core grunt for rendering.
