Fire Strike is quite a different story. This scene uses tessellation, shadow maps, post-processing filters and lots of other effects. As a result, the graphics subsystem load is so high that we can easily compare graphics cards between each other, especially in terms of graphics scores:
The GeForce GTX 690 is 50% faster than the Radeon HD 7970 here. The latter, in its turn, is better than the GeForce GTX 680 but then the picture changes. The GeForce GTX 670 is not slower but faster than the Radeon HD 7950. The GeForce GTX 660 Ti is equal to the Radeon HD 7870, and the GeForce GTX 660 to the Radeon HD 7850. Judging by the 3DMark results, AMD should fill the gap between the Radeon HD 7850 and the HD 7770 with some new product because the GeForce GTX 650 Ti is preferable to the Radeon HD 7770 among the most affordable gaming graphics cards.
The physics subtest doesn’t need our commenting:
AMD-based products look preferable in the combined subtest that loads both the CPU and the GPU.
Excluding the Radeon HD 7770 again.
