$this->bbcode_second_pass_quote('', 'T')hree floating-point operations per clock period per core at 1.296 GHz works out to 933 GFLOPS (billions of floating-point operations per second) for single-precision computations, a record for a production chip. (Intel made an experimental 80-core floating-point processor in 2007 that exceeded 1 TFLOPS, but never brought it to market.) The GTX family can also handle double-precision math, which will help in professional applications; in this mode, the GTX 280 delivers over 90 GFLOPS. The chip has 142 GB/s (gigabytes per second) of memory bandwidth over a 512-bit memory interface. It can manage a gigabyte of 1.1-GHz GDDR3 frame-buffer memory.
These are truly astounding numbers for a single-chip processor, suggesting that the GTX 280 is an order of magnitude faster than the theoretical capability of current quad-core PC CPUs.
