AMD64 Processor Architecture

Very large level one (L1) and level 2 (L2) on-die cache.
With 128 kbytes of L1 cache and 1 Mbyte of L2 cache, the AMD Athlon 64 processor is able to
excel at performing matrix calculations on arrays.
Programs that use intensive large matrix calculations will benefit from fitting the entire matrix in
the L2 cache.
Processor core clock-for-clock improvements, including larger TLB (Translation
Look-Aside Buffers) with reduced latencies and improved branch prediction
through four times the number of bimodal counters in the global history counter,
as compared to seventh-generation processors.
These features drive improvements to the IPC, by delivering a more efficient pipeline for CPU-
intensive applications.
CPU-intensive games like Comanche 4 and Unreal Tournament benefit from these core
improvements.
Introduction of the SSE2 instruction set, which along with support of 3DNow!
Professional, (SSE and 3DNow! Enhanced) completes support for all industry-
standard 32-bit instruction set extensions.
64-bit processing
A 64-bit address and data set enables the processor to process in the terabyte space.
Many applications improve due to the removal of the 32-bit collar.
