AMD FX9590 (5ghz) Review (w/ Gigabyte 990FXA-UD5)

Our AMD FX9590 was taken direct from the retail channel, so no hand picked ‘media review sample' today. No fancy box either with a heatsink included in the bundle – this is strictly a ‘processor only' deal. An AMD reference cooler would melt under the pressure from this 220watt TDP monster and we would imagine system builders will be educated by AMD on what coolers they should be using.

We got hold of an internal pack from AMD and they recommend the following coolers (or better):

• Corsair H80i (fan rpm >2800).
• Antec Kuhler H2O 920 (fan rpm >2330).
• Coolit ECO II-120FB, Fat Boy (fan rpm>2383).

If you were paying attention earlier in the review, then you would have seen that the AMD FX9590 is a PileDriver processor in the Vishera family. It is built on the same 32nm process as the FX8350, so we would imagine these are hand picked wafers, the cream of the crop lifted directly from the line.

Does the FX9590 run at 5ghz all the time? AMD say “The AMD Turbo Core frequency applies when half of the available cores are active.” In plain terms, only when 4 cores or less are active.
