ja hastigheden ændres, på de nyere er de gået over til en anden arkitektur størrelses mæssig, fra 130 nanometer til 90 nanometer.
In essence, there isn't a great deal of new ground to cover with the Athlon 64 FX-57; it is 200MHz faster than the FX-55, meaning that it is clocked at a healthy 2800MHz. One would expect the former to deliver slightly higher performance than the latter, as with the gap between FX-53 and FX-55 that we experienced at the back end of last year.
However, that is not all that is going on with the Athlon 64 FX-57. It is built on a fabrication process that is new ground for Athlon 64 FX-series processors, making it unique in comparison to other members of the FX-series, which have thus far been manufactured on a 130-nanometre process until now. Along with the process change, there is also the inclusion of SSE3 instructions, an improved memory controller and improved multimedia performance.
The Athlon 64 FX-57 is based on the 90-nanometre Silicon-On-Insulator process that has thus far been used on the Winchester, Venice, San Diego and Toledo cores. Toledo is the core that is used for the Athlon 64 X2 processors, and is actually two cores on one die - you can read more about dual core Athlon 64's in our Athlon 64 X2 4800+ preview. Winchester was the first generation 90-nanometre core that AMD produced, while Venice and San Diego are a revised process that got rid of some of the bugs that were in the original Winchester core revision.
