NVIDIA's Tesla GPU Computing Launch
 

The basic unit of the current Tesla line, the Tesla C870, should be very familiar to anyone who's seen the GeForce 8800. It's essentially an 8800 GTX--a 575MHz core clock and 128 SPs at 1.35GHz--with 1.5GiB of GDDR3 RAM. Of course, it's not quite an 8800 GTX--there are no display outputs at all on the card
