Following also in traditional footsteps, the FX62 processor will debut with a core clock speed that is 200MHz higher than that of the fastest currently available X2 processor. The new 940 design also incorporates an additional 512K of L2 cache per core. In order to ensure stability and functionality at this increased speed, and with the presence of increased cache, FX62 chips will debut with a core voltage which is equal to, or greater than that of the X2 processors.

These two increases will result in the chip's Thermal Power rising up by 36W over the X2 model, as well as an increase in transistor count from 153.8 Million to 227 Million. This increase in transistors will result in a larger die, which is approximately 47mm2 larger than that found on the X2 chip. As with the X2 chip before it, the FX class processors will not enjoy an upgrade in process technology, sticking with 90nm as opposed to moving to 65nm. Unlike the X2 chips however, there will be no low power variants of the FX class chip available. Users should have no qualms, however, as many new motherboards will feature enhanced (8 Phase) power circuitry, which should be more than sufficient, as previous 3 and 4 phase systems had the potential to handle the thirsty FX60.
