AMD is revising their Athlon 64 and Sempron cores, slowly bringing it all over to socket 939 and 90 nm process , and adding SSE3 support all round . This is good because we can now get more performance , for less money, less power consumption , and better overclocks .
The first chips will be shipping tomorrow , and the new 90nm replacement for the athlonFX the Athlon64 4200 will begin shipping april 15th . These new chips will not need a bios flash to WORK, but it will need one to fully implement the SSE3 instructions .
