What's the differences between GTX295 and Tesla GPU?

I didn’t find the details about tesla GPU, who can show me the defferences between them??
thank you

The current Tesla cards are pretty much a GTX 285, but with more device memory, slightly different clock rates, no video connector, and better testing.

The GTX 295 is two separate CUDA devices sharing a PCI-Express switch. Each device is like a GTX 275 underclocked to ~1.2 GHz.

Wikipedia has a great comparison of NVIDIA cards:

Is the speed between GPU and global memory for the two GPUs same?
