Hopefully this is just out of date, and should be removed. If it's still true, "ATI" should be updated to "AMD." (And if it's still true, then that's a bummer.)Why are the ATI x86 FLOP numbers half of the ATI native FLOP numbers?
Due to a difference in the implementation (in part due to hardware differences), the ATI code must do two force calculations where the x86, Cell, and NVIDIA hardware need only do one. This increases the overall native FLOP count for ATI hardware, but since these are not useful FLOPS in a sense, we did not include them in the x86 count.
The "Contact Us" page sent me to this forum; can someone get in touch with whoever should update that FAQ page?
