Advanced Micro Devices on Tuesday confirmed rumours about FX enthusiast-class microprocessors with extreme clock-rates. The new products are the world’s commercially available microprocessors with guaranteed maximum speed of 5.0GHz. AMD FX-9000 series CPUs will be available initially in PCs through system integrators, but not to end-users.

 

“At E3 this week, AMD demonstrated why it is at the core of gaming. The new FX 5GHz processor is an emphatic performance statement to the most demanding gamers seeking ultra-high resolution experiences including AMD Eyefinity technology. This is another proud innovation for AMD in delivering the world’s first commercially available 5GHz processor,” said Bernd Lienhard, corporate vice president and general manager of client products division at AMD.

There will be two extreme FX microprocessor modules available: FX-9370 clocked at 4.40GHz with 4.70GHz maximum Turbo Core frequency as well as FX-9590 clocked at 4.70GHz with 5.00GHz maximum Turbo Core frequency. The new FX chips will have eight Piledriver cores and will come in AM3+ form-factor. Nonetheless, given the fact that there are currently few mainboards that officially support chips with such high power consumption, the new chips are not drop-in compatible with existing infrastructure.

The rumours about code-named Centurion chips with ultra-high clock-speeds have been floating around for some time now. Originally, it was expected that limited edition FX chips will conquer 5.0GHz clock-speed with all of its eight cores, and will therefore will be competitive against Intel’s Core i7 high-end desktop (HEDT) products in LGA2011 packaging. Moreover, Centurion was supposed to reach the frequency with air cooling and remain stable inside desktop PCs.

In reality, AMD managed to boost default clock-speed of Vishera eight-core processors to 4.70GHz, or by 17.5% compared to the FX-8350, the top-of-the-range chip available for end-users today. Moreover, the chips will be available to system makers only, which suggests that they need more sophisticated cooling systems than typically utilized by end-users.

AMD’s current top-of-the-range eight-core FX-8350 microprocessor is clocked at 4.0GHz and in terms of performance is typically behind Intel Core i7-3770K and Core i7-4770K (4 cores with HT, LGA1155) as well as Core i7-3970X (6 cores with HT, LGA2011). While in video games its performance can easily be improved by overclocking, in applications where performance difference equals or exceeds 50%, a 17.5% clock-speed boost will hardly help much.

Several years ago AMD already offered so-called TWKR chips, which were available in quantity of less than 100 units worldwide, but which attracted loads of attention to Phenom II processors in mid-2009.
