The new CPUs incorporate AMD's "Piledriver" architecture, and will be available on launch as an eight-core, six-core, and four-core processors. In a document received by Chinese site EXPreview titled "2012 consumer-level desktop platform Quick Reference Guide for Desktops", AMD listed FX processors and the upcoming release of the APU model, the core number, frequency, and the TDP specifications.

The flagship FX-8350 is listed with a 4.00 GHz clock speed (4.20 GHz TurboCore speed), eight-cores, and TDP of 125W. The FX-6300 features 3.50 GHz clock speed (4.10 GHz TurboCore speed), six-cores and TDP of 95W. To round off the list, the FX-4320 features 4.00 GHz clock speed (4.20 GHz TurboCore speed), four-cores and TDP of 95W. None of the FX processors support integrated GPU, but support a full list of "Piledriver" features, such as AMD Perfect Picture HD, AMD Steady Video 2.0 Technology and AMD Wireless Display.

In addition, the leaked document confirms clock speeds, integrated GPU, and GPU cores of several FM2 A-series APUs, such as the A10-5700, A8-5500 and E2-1800.

    More performance at the same frequency than the FX81xx CPUs and a 4GHz frequency, yet it doesn't need a higher than 125w TDP? The FX-8350 is looking like a pretty darned good step-up over the FX-8120 and FX-8150.

    Still...its not the best thing around.

    you know... at only 95 watts, and a 4ghz base frequency, and also improved IPC on piledriver, the FX4320 could be quite the potent value cpu. would quickly make the i3's obsolete at any rate. heres hoping they deliver!

    Come on AMD!!! this is the last chance you have to beat intel and stop it from making a monopoly!

    You might be surprised. Disable one core per module to eliminate resource sharing (letting the still active core of each module get a significant performance per Hz boost while cutting power consumption by 30-40%) and overclocking the CPU and CPU/NB freuqneyc (increases the L3 cache frequency) on the FX-8120 and the FX-8150 can make them able to compete with the K edition i5s. Doing the same with this FX-8350 might let it be able to top Intel in lightly threaded performance until Haswell launches and even compete with the quad core LGA 1155 i7s in highly threaded performance with this *mod* and beat them without it.

    It might actually be one of the best things around if used properly.

    It might actually get Intel to update the i3s with Ivy if they intend to do that at all until Haswell comes out. Ivy i3s with raised frequencies relative to the Sandy i3s could make a good middle-ground between the i5s and the older i3s that can compete with AMD's quad core Vishera and Phenom II CPUs better.

    Is this something that's confirmed or just BS? i believe we all want the source of this statement.

    That was with mere thread-scheduling improvement rather than disabling of cores, had a frequency disadvantage to the normal core configuration, and it stil managed a 10-20% improvement (usually closer to 20%). The CPU/NB frequency controls, among other things, the L3 cache frequency (defaults to 2.2GHz). Increasing it to the CPU frequency would make it a full-speed cache and that helps a lot in performance per Hz of the CPU frequency too. This is not BS.

    Also, with a 30-40% power consumption drop (you can't expect halving the core count to not reduce power consumption greatly, can you), overclocking headroom increases (and it was already pretty high). These CPUs can probably break 6GHz on air. Admittedly, that is an estimation rather than provable fact right now, but my estimations are usually pretty good and considering that the current FX 81xx CPUs can already break 5GHz on lower end Air coolers in the same configuration (they can reach for 4.5GHz on their stock coolers with all eight of their cores, what do you expect), chances are good that these CPUs which have higher thermal headroom at a given frequency (and don't need as high voltages to reach said frequencies) can hit a higher frequency.

    Another thing to keep in mind is that they already have higher performance per Hz than the FX-81xx CPUs did.

    If I were putting together a new machine soon, I'd probably pick the 4x4GHz @95W one.
    Too bad there still doesn't seem to be a compelling reason to dump my near 4 yrs old Phenom II. 4 cores at 3GHz is still good enough.

    Damn, 4 yrs and if the GTX280 hadn't been such a dud, it could still run new games at max settings as originally purchased. Progress really isn't racing on like it used to...
