I can’t figure out what is the theoritical maximum bandwitdh of ION LE platform ?
I ran the bandwidth test included in the CUDA sdk 3.0 and got results between 5 to 6 Gb/s for a device to device MemCopy.
AFAIK Ion and the 9300M/9400M chipset are one and the same thing (technically MCP79a is the chipset name). Ion LE is also the same chipset, just with one MP fused off. The only major difference between any of the MCP79a versions is the gpu core clocks and the addition of DDR3 support in some cases.
