Benchmarks: Battlefield 3, Crysis 3
The Radeon HD 7990 is the fastest graphics card we have tested in Battlefield 3 at 2560x1600 as it just managed to outpace the GeForce GTX 690, beating it by a 4% margin. The 7990 was also faster than the 7970 GHz Edition Crossfire configuration which was surprising. When compared to the GeForce GTX Titan the 7990 was 39% faster, while it crushed the GTX 680 by a 96% margin and the 7970 by a 101% margin.
Despite beating the GeForce GTX 690 by a 4% margin in our frames per second testing, the Radeon HD 7990 was actually 30% slower when it came to frame time performance. Frame time performance is a weakness of Crossfire technology (at least for the moment) and this is where the 7990 is going to struggle.
Although the Radeon HD 7990 was able to average 37.1fps in Crysis 3 at 2560x1600, making it 57% faster than the 7970 while also matching the 7970 GHz Edition cards, it was 10% slower than the GeForce GTX 690.
Frame time performance in Crysis 3 does not appear to be a problem for Crossfire technology, as the Radeon HD 7990 took just 31.6ms between frames at 2560x1600. That said, it was now 20% slower than the GeForce GTX 690, but 47% faster than the GTX 680.
