AMD FX-9370 and FX-9590 processors were launched last month, and only recently they started to appear in retail stores. The latest CPUs have the same number of cores and the same size of L3 cache as AMD FX-8300 series of chips, but they offer extreme performance, thanks to much higher base and Turbo Core frequencies. The prices and power consumption of FX-9000 series CPUs is also on the extreme side. The flagship FX-9590 costs more than $800, and has 220 Watt TDP. Naturally, the TDP is only a guideline for heatsink manufacturers, and, as was shown by some FX-9590 reviews, actual power consumption of the CPU is lower than 220 Watt. The power consumption is still much higher compared to other AMD chips, which means that better quality, hence more expensive, cooling solution is required. Besides that, higher processor power needs a motherboards, that can provide that much power to the chip. Up to this week, none of the mainrboards had official support for FX-9xxx processors. However, days ago two motherboard manufacturers added support for FX-9590 and FX-9370 CPUs to their premium products.
Gigabyte added support for both CPUs to GA-990FXA-UD3 (rev. 4.0) and GA-990FXA-UD7 (rev. 3.0) motherboards. CPU support list for ASrock 990FX Extreme9 motherboard also shows FX-9370 and FX-9590 processors as supported. The ASRock board requires new BIOS P1.40 to work with the processors, while the Gigabyte boards do not need BIOS upgrade. We could not find motherboards from other manufacturers, that support FX-9000 series microprocessors.
