Does anyone know the difference between the AMD64 Newcastle and the AMD 64 Winchester? The only difference i can see is that the Newcastle is 130nm and the Winchester is 90nm - but i have no idea what a 'nm' is. Any help is much appreciated d

The winchesters run cooler and if u get the right one, seem to o/c higher. Some mobo's with older BIOS's wont boot with winchesters but most sold now are fine. Winchesters also seem to be slightly faster clock for clock than NC's.

nm is nanometre. It's referring to the physical size of the circuits in the chips. They've been shrinking them ever since the first true 'chips'.

Why shrink them?
When they create chips they make several hundred on one large piece of silicon (called a wafer). If you shrink your CPU manufacturing process then you can fit more chips onto one wafer, so you save money on each chip and get increased profits.

The smaller processes also theoretically allow more performance for various reasons, but I can't be arsed to go into what little detail I know (which isn't all that much, really) - try google if you're interested... :wink:
