AMD’s beast of a chip, the 8-core FX-9590, has been spotted on a retailer’s website along with the lesser powered FX-9370. But good luck getting a motherboard that can support the 9590’s required TDP.

During June’s Electronic Entertainment Expo in Los Angeles, AMD announced the first commercially available 5GHz processor: the 8-core FX-9590.

The FX-9690 technically isn’t clocked at 5GHz. Its base speed is clocked at 4.7 GHz, and it hits 5GHz with the help of a turbo core. AMD also launched another chip in the 9000 series with a slightly slower clock speed, the FX-9370. This chip has a base clock speed of 4.4 GHz and a turbo clock speed of 4.7 GHz.

Both chips come equipped with eight AMD “Piledriver” cores and have a 16-MB of on-chip cache as well as an unlocked clock multiplier.

However, there is a caveat. In order for these processors to run they need to be provided with 220W of power. That’s how big the chip’s TDP is. With a TDP like that, the number of motherboards that can support the chips are severely limited. One OEM that has released a PC that sports an FX-9590 equips it with an MSI 990FXA-GD80 V2 motherboard and a 1200W PSU.

CPU World spotted a FX-9590 on sale at TigerDirect for $829, though only its slower clocked sibling the FX-9370 was available retailing for $319. As AMD has said that this chip is going to OEMs first, it is more widely available in prebuilt systems.
