Hi, I am getting internal bandwidth test on 8800 Ultra at 80GB/s. Cool. This is when I run the example “bandwidthTest”:
Quick Mode
Device to Device Bandwidth
.
Transfer Size (Bytes) Bandwidth(MB/s)
33554432 80124.4 External Image
HOWEVER
alignedTypes program outputs the best 31MB/s for aligned I32 or RGBA8. External Image
how can I achive full bandwiths when I am really accessing data, not just memCopying them?
