Power Consumption


AMD FX-8150 CPU - Bulldozer CPUs are finally here!

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.

    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.
