AMD’s Radeon HD 7970 continues demonstrating strength in compute performance. Two GeForce GTX 680s present impressive FP32 numbers. However, with FP64 rates at 1/24, you end up with a pretty dismal comparison.
A 384-bit aggregate bus helps AMD’s cards push more internal bandwidth, while PCI Express 3.0 compatibility facilitates an interface bandwidth increase as well.
