When AMD announced the FX-9590 last year it was seen as an attempt to connect back with its enthusiast community. Boasting a clock speed of 5 Ghz, the chip was faster than anything else on AMD's lineup. Even then, it would have a hard time competing with Haswell and Ivy-Bridge E. Now, according to our sources, the FX-9590 is reaching the end of its life cycle only after a mere 9 months.
FX-9590 Exiting before its time, is Heat Problem the real reason?
Heat was naturally going to be a problem the 9590 would have to face after being able to clock at 5 Ghz. The TDP of the board is very high 220 Watts. This brings strong problems in areas of motherboard compatibility with a variety of hardware. Another problem is the cooler choice for this heat produced. However, perhaps the most valid reason for the exit of the FX 9590 is the release of Mantle.
Mantle, as we know, works by cutting down CPU bottlenecks and therefore allows applications to utilize the CPU and GPU capabilities more effectively. This allows greater control over the hardware installed. Therefore, due this better utilization, the clock speed of CPU's in gaming and other applications could be less important, with greater focus being paid towards better utilization of available hardware resources. This leaves the 9590 rather in the middle, with it's selling point left obsolete.
Coming towards the possible improvements in the successor to the 9590. It can be safely assumed that the TDP class of the new processor will be the same 220 Watts as the current model. In addition, a significant improvement would perhaps be the capability of the successor to achieve 5 Ghz as base frequency. In the case of the 9590, the 5 Ghz only applied to Turbo Clock.
As always, all these are after speculations and all we can do is wait for further word from AMD itself.
