This review is from: AMD FX-8320E - FX-8000 Series Vishera 8-Core 3.2GHz (4.0GHz Turbo) Socket AM3+ 95W Desktop Processor - FD832EWMHKBOX
Pros:
Lots of cores
Half as many floating point modules
Replaced my heater in my computer room
Low wattage version of the FX-8320, works great in 970/760g chipset motherboards
Cons:
If you don't disable Active Power Management in the BIOS it seems to throttle such that it never pulls more than "~70 watts" (see other thoughts)
Expensive compared to other models that are similar and run better
Overall Review:
AMD really messed up their active power management to no end. It's unmodifiably locked to (according to HWinfo64 while running Intel Burn Test) around 70 watts. Since I overclocked it, I obviously disabled it, but it doesn't even let the thing push past 2.8ghz under full (100%, load no more, IBT something or other) load. Under half load it goes nuts at stock settings (3.2ghz / 4ghz turbo) and runs games / pushes turbo rather properly. Because of this, I must overclock it without turbo (not losing much really, since the turbo is only fully adjustable in AMD Overdrive and not in the BIOS of my ASRock 990FX Extreme9). I keep all of the power saving settings in BIOS turned off except for Cool'n Quiet (so it can adjust ghz in steps like a normal CPU without turbo and stuff), set it to 4.2ghz @ 1.25 VID with 50% LLC, only ever gets toasty (CM Seidon 120v cooling it, push/pull fans) if I run Intel Burn Test, and not very toasty (62C or so max). Battlefield 3 runs very well along with everything else, and for much cheaper than most Intel processors in its price range.
With the BIOS option of "one core per unit" in number of active cores, I was able to overclock this further than normal at a lower VID (it still got super toasty).
With standard all cores active, I managed:
4.5ghz @ 4.15 ish vcore
With one core per unit, I managed:
4.7ghz @ 1.395 ish vcore
It ran Battlefield 3 much worse, but Starcraft 2 slightly better (low thread count games will see small performance gains while games optimized for AMD 8 core processors will see a decent loss), and it generated significantly less heat (lasted like 5 minutes running Intel Burn Test before I killed it, instead of like 2 minutes with all cores @ 4.5ghz).
