ComputerWorld writes AMD has three incoming FX processors; the FX-4170, FX-6200 and FX-8150 (WOX). The FX-4170 is the first AMD chip to exceed 4GHz, it offers a 4.2GHz clockspeed and a 4.3GHz Turbo. The FX-8150 (WOX) includes a liquid cooling kit, but at $398.29 it's considerably more expensive than the air cooled FX-8150 ($269.99 at Newegg).
AMD FX-4170 will be the first production AMD processor with clock speed greater than 4 GHz. This quad-core CPU is clocked at 4.2 GHz, and up to 4.3 GHz when two or more cores are idle. As all retail FX-Series products, FX-4170 has unlocked clock multiplier, and comes with 8 MB L3 cache. Thermal Design Power of this model is 125 Watt. The chip can be pre-ordered for $153.27, and we hope that the price will drop a bit once the FX-4170 is released.
