Xtreme Systems.org have posted information on AMD's 90 nanometer Athlon 64 processors with Benchmarks:
The 90nm A64 is not a simple die shrink but features several enhancements, such as: SSE3 implementation (?) Improved hardware data prefetch mechanism Increased number of writing combine buffers (D0 stepping A64's can now combine up to four non-cacheable streams compared to 2 on the C0 and CG stepping A64's) Improved on-die memory controller with more advanced open page policy On-die thermal throttling Black Diamond Low-K technology (slower less power hungry transistors in less used sections and faster and more power hungry transistors in frequently used sections of the cpu)
