    Would be nice to know how good it is at folding.
    If you find any thread about it that's legit please post.. I'll do the same, If i come across anything on the interwebzz :nerd:

    Sorry to appear negative, but have you seen the powerconsumption?
    Sweclockers did a test, and LOOK AT THAT OH MY GOD THE POWER

    i so wished this was going to be a lot better than it has been 13.5k ppd that not good and the power draw this mean it a no go for folding:cry:

    whats the difference between an 1100T and this besides 30W more for 2 extra cores whats the average PPD for an 1100T in comparison to the 8150FX

    Are those power figures confirmed? I do realise they use more but I don't believe it would be that much. First of all, overclocked it uses 200W more than the unclocked CPU?! almost 300W more than an i7-2600K?

    I'm guessing anything past 4.6 GHz OC for FX-8150 has lesser 'ROI' the further you OC it.
    Maybe this is why it needed liquid helium to break P4's 8GHz record.

    Those figures are for TOTAL SYSTEM DRAW.....not for the processor itself. The CPU socket is completely incapable of providing that much power to the processor. Also, there's no way of knowing for sure exactly what the bios settings were, as some settings have a direct impact on system power draw.

    Yes, it is the total system draw, but still, quite the power needed to run it!

    Here are the components used for testing:
    Processors

    AMD FX-8150
    AMD FX-8120
    AMD A8-3850
    AMD Phenom II X6 1100T
    AMD Phenom II X4 980
    Intel Core i7 2600K
    Intel Core i5 2500K
    Intel Core i7 980X
    Intel Core i7 975
    Intel Core i7 870
    Intel Core 2 Quad Q9550

    Motherboards

    Asus Crosshair V Formula (AMD 990FX)
    Asrock A75 Pro4 (AMD A75)
    Asus P8Z68-V Pro (Intel Z68)
    Asus Rampage III Extreme (Intel X58)
    Asus P7P55D Deluxe (Intel P55)
    Asus P5Q Deluxe (Intel P45)

    Memory

    4 GB Corsair Dominator GT, 1 866 MHz, 9-9-9-24 (AM3+)
    4 GB G.Skill 1 066 MHz, 5-5-5-15 (LGA 775)
    4 GB Corsair Dominator GT, 1 600 MHz, 8-8-8-24 (other)

    GPU AMD Radeon HD 6970
    HDD Intel 510 250 GB
    PSU Cooler Master Silent Pro Gold 1 200 W
    Screens

    Samsung Syncmaster 305T
    LG Flatron W2420R

    OS Windows 7 Ultimate 64-bit

    And a link to the original article (google translated swedish-english)

    I'm starting to wonder if there's a problem with the power management of these chips....or even the chipsets. The processor itself does have a pretty hefty power draw....but the processor can't draw enough power on it's own to skyrocket system draw like that. At stock clocks, the system should be within a few watts of a Core i7 2600K. At full load (and OC'd to 4.6ghz @1.4vcore), the processor still stays below 300watts (according to AMD's power specs)....

    If you subtract idle from load you will have total power of the cpu. The test is only using the cpu. The 8150 uses over 300 watts. And yes, 1 8pin EPS can supply 300 watts and even more than that if need be.

    Actually, subtracting the idle from the load does not give you the CPU power draw due to efficiency fluctuations of the PSU, plus the chipset, plus memory, VRM, etc.... When under load the chipset, VRMs, and PSU will all consume more power, making your calculation completely inaccurate.

    Hilbert overclocked the FX-8150 to 4.6ghz using 1.44 vcore. The processor socket is only capable of delivering 145amps (AMD spec). 1.44v x 145a = 208.8watts (this is the maximum power draw as per Watts law)
    Hilbert's review is here: http://www.guru3d.com/article/amd-fx-8150-processor-review/8

    Now, considering that the socket is only capable of supplying 145amps (as per electrical specification), to reach 300watts you'd have to increase the vcore to 2.07volts.....which would make the temperature uncontrollable without using LN2....
