bandwidth in emulation mode so high bandwidth in emulation mode?

Accelerated Computing CUDA CUDA Programming and Performance

Hi all,

I have got a bandwidth of over 800 GB/s in emulation, as attached.
Emulation mode seems not realistic.

Is it true that emulation mode has only poor performance in computation, not in the bandwidth?

Well, if somebody has a snapshot for Geforce 9800GTX or similar,
pls show the bandwidth test result for my understanding.

Thank you in advance.

The bandwidth numbers in emulation are meaningless ( there is no data movement)
