Advanced Transfer Cache

From Wikipedia, the free encyclopedia

The Advanced Transfer Cache (ATC) is Intel's name for the L2 cache contained within their processors, starting with the Pentium III "Coppermine". In "Coppermine" it offered a significant boost in cache performance resulting in notable per clock performance gains for the CPU when compared to its predecessor, "Katmai".

Characteristics of the Pentium III "Coppermine" ATC cache:

  • Cache is at the same clock speed as the processor
  • 256-bit data bus
  • Improved buffering between the cache and CPU
  • Significantly lower cache latency
  • 8-way associativity
