Closer Look: AMD FX-9590
The AMD FX-9590 CPU sits on top of the FX lineup of CPUs. As such, it touts the highest clock speeds of all of AMD’s FX series CPUs. The FX-9590 runs at 4.7GHz out of the box and has a maximum turbo clock speed of a massive 5GHz. The FX-9590 is, of course, a black edition CPU, so there may even be a little more headroom in there. This is especially true considering the fact that the CPU has been out for a while now and yields are certain to be higher and more stable.
The main difference in the FX-9000 series CPUs over the FX-8000 series CPUs is the RAM support. The FX-9590 and the FX-9370 support DDR3 RAM with speeds up to 2133MHz on a 990FX motherboard. The FX-8370 and the other FX-8000 series CPUs only support DDR3 RAM up to 1866MHz. You would undoubtedly be able to overclock your RAM using the FX-8000 series, but the higher native support sets the FX-9590 and FX-9370 a little apart from the rest of the series.
Considering the fact that the FX-8370, with a 4GHz clock speed, was recently released with an MSRP of $199, the price drop of the FX-9590 to $229 represents an excellent price point in my opinion. For only $30, the FX-9590 comes with the higher RAM support speed and 700MHz of extra oomph. Of course, you are looking at drawing about 95W more power with the FX-9590. The higher end FX-9000 series CPUs have a TDP of 220W, compared the 125W of the FX-8370 CPU. For that matter, the FX-8370E CPU, which demonstrated excellent overclocking capability and performance, sips a measly 95W of power.
Of course, it is my opinion that the customers who will be most interested in the FX-9590 probably won’t be as concerned about taking it easy in terms of power usage. AMD recommends using the FX-9590 with the high-end Radeon R9-290X series of video cards, which tend to suck up a lot of power as well. I know that, for me personally, if I’m going to go all out for my gaming rig, I’m not going to let 95 extra Watts of power to deter me.
