System Memory - Mainboard & GPU

  • 512 MB of Unified GDDR3 RAM
    • Unified Memory Architecture
    • Reduces cost and complexity of the motherboard design
  • 700 MHz DDR
    • Effective transmission rate of 1.4 GHz on the 128-bit bus
  • Unified memory architecture (GPU & CPU Access)
    • GPU 10MB eDRAM
  • 128-bit interface to ATI's memory controller

Memory Bandwidth

   

  • 32 GB/s GPU to eDRAM bandwidth
    • 2 GHz @ 2 accesses per clock cycle on a 64 bit DDR bus
  • 22.4 GB/s memory interface bus bandwidth (low latency path to CPU cores)
    • 700 MHz @ 2 accesses per clock cycle (one per edge) on a 128 bit bus
  • 256 GB/s memory bandwidth to EDRAM
  • 21.6 GB/s front-side bus
  • Southbridge bandwidth of 500 MB/s.
