The new FX-8370 processor from Advanced Micro Devices has set a world record for silicon processor speed, the company announced Tuesday. Clocking in at 8722.78 MHz, the processor shattered the previous CPU frequency record, which was also set by an AMD FX series processor, the company said.

The speed was verified by HWBOT, which benchmarks developments in computer hardware performance. HWBOT focuses on overclocking, which involves setting a CPU to run faster than it was designed to go. AMD said the FX-8370, based on the "Piledriver" x86 core architecture, was tested by "famed Finnish overclocker 'The Stilt,' " who "pushed the envelope of silicon overclocking to the extreme."

According to Bernd Lienhard, corporate vice president and general manager for AMD's client business unit, the FX series' record-breaking frequencies will enable "extreme multi-display gaming and HD content creation." The FX-8370 is one of three new FX processors rolled out by AMD Tuesday.

Designed for Gaming, Power Users

All of AMD's new processors feature eight X86 cores. Priced at $199.99, the 125-watt FX-8370 has a base clock speed of 4 GHz and a maximum clock speed of 4.3 GHz. The two power-optimized CPUs -- the FX-8370E and the FX-8320E -- each draws up to 95 watts of power. The FX-8370E, also priced at $199.99, has a base clock speed of 3.3 GHz and a maximum of 4.3 GHz. The lower-cost FX-8320E, which has a suggested e-tail price of $146.99, clocks in at 3.2 GHz (base) to 4 GHz (maximum).

Designed with gaming enthusiasts or business power users in mind, the FX series processors are recommended for use with AMD's Radeon R9 graphics cards. According to AMD, the FX-8370 is ideally paired with its 990FX board and DDR3-1866 memory. The board and memory recommended for the other two CPUs are the AMD 970 and the DDR3-1866.

AMD's FX series line also includes the 220-watt FX-9590, which the company recently reduced in price to $229.99. Both the FX-9590 and the FX-9370 are also available with closed-loop liquid cooling for quieter operations. Those carry recommended e-tail prices of $282 and $265, respectively.

Target: 'Tweakers and Tuners'

We reached out to James Prior, AMD's product review manager, to learn more about the new FX processors.

"The main target for FX are consumers who are interested in building a capable, budget friendly, high performance PC that serves multiple needs," Prior said via e-mail. "With 8 cores and unlocked core frequency options, it is popular with tweakers and tuners who like to hand-tune their PC for maximum performance without additional cost."

Prior added that the new 95-watt processors are designed to let "users of older motherboards that are restricted to 4- and 6-core processors to drop-in upgrade to FX 8-cores also."

According to Prior, the previous CPU clock frequency record was set by AMD's FX-8150 in October 2011.

"Today's record handily beats that record," he added.
