In 3DMark 2011 the new Radeon HD 7790 is 31-36% ahead of the Radeon HD 7770 GHz Edition and 9-11% behind the Radeon HD 7850, beating the latter in overclocked mode. Meanwhile, the GeForce GTX 650 Ti Boost is 11-19% faster than the ordinary GTX 650 Ti and 5-7% slower than the GTX 660. Comparing the two new products, the Radeon HD 7790 is somewhat better at the Performance settings but the GeForce GTX 650 Ti Boost is ahead at the Extreme settings.
We can see the same picture in the first two test scenes from 3DMark 2013: the Nvidia products outperform same-class AMD solutions. The heaviest test Fire Strike Extreme highlights the weak side of the Radeon HD 7790, namely the small amount of its onboard memory, which leads to a performance hit. The GeForce GTX series cards all have twice the amount of memory and cope with Fire Strike Extreme much better.
Unigine Valley Bench
Although the new Radeon HD 7790 is up to 30% faster than its predecessor Radeon HD 7790 GHz Edition, the GeForce GTX 650 Ti Boost is faster still. The gap is especially impressive than both cards are overclocked.
Resident Evil 6 Bench
The GeForce GTX series is superior in the Resident Evil 6 benchmark, too:
Now let’s move on to actual games.
S.T.A.L.K.E.R.: Call of Pripyat
Same-class products from AMD and Nvidia are comparable in this game when we don’t use antialiasing. But as soon as we enable 4x MSAA, the Nvidia-based solutions go ahead. Take note that the Radeon HD 7790 and GeForce GTX 650 Ti Boost fit snugly in between the HD 7770 GHz Edition with HD 7850 and the GTX 650 Ti with GTX 660, respectively.
