Hi, I was just wondering (as I am going for a upgrade, discussed in a separate thread), we have come across many variants of Athlon processors with some typical numbers, like Athlon 64 2800+, Athlon 64 3000+, Athlon 64 3200+, Athlon 64 3500+, etc. What do the numbers 2800+, 3000+ etc signify? Is there any relation between these numbers and the clock speeds of the processor and also the FSB speed? I have also heard of different core designs like Newcastle, Venice, etc in Athlon processors. What does those signify? Thanks in advance.
