Phenom II X4 810 Conclusion

Phenom II X4 810 Features

Major feature enhancements for 45nm AMD Phenom II:

  • Enhanced Total Cache: 6MB (L2 + L3) on X4 810
  • Cool'n'Quiet 3.0 Technology: Additional power states, significantly (~40%) lower idle power and lower power consumption under moderate loads
  • Massive headroom using extreme and experimental cooling techniques

Major silicon enhancements for 45nm AMD Phenom II:AMD_Phenom_II_X4_Logo.jpg

  • 45nm immersion lithography manufacturing technology enables higher frequencies, tighter tolerances and lower current leakage
  • 4MB L3 cache (up from 65nm Phenom's 2MB) on X4 810
  • 2-cycles faster than 65nm Phenom L3
  • Increased DRAM bandwidth
  • Cache flush on halt: Core's L1 and L2 flush into shared L3 after a core enters a halt state allowing the core to drop to a lower speed and save power
  • Path-based indirect branch prediction
  • 2x increase in core probe bandwidth
  • Larger load/store buffering / larger floating point buffering / reduced MAB (missed buffer) lifetime
  • Improved LOCK pipelineing: (LOCK is an instruction prefix) this improves performance when multiple LOCKS are in process simultaneously
  • FP MOV compute optimization: Floating point register-to-register move instruction improvements
