Videocardz.com compiled a set of performance figures slide that puts the upcoming Geforce GTX 660 and the Geforce GTX 650 graphics cards against a couple of older Nvidia graphics cards as well as the AMD Radeon HD 7850 and the Radeon HD 7750.

Bear in mind that these figures are pretty much recompiled Nvidia performance slides that we seen before so a dash of salt is needed as these results are most likely the best case scenario. Of course, Nvidia generally wants the GTX 660 to compete against the Radeon HD 7870 and these two cards will be evenly matched in most scenarios, but it is always better to show that you can beat the competition, even on slides, thus you see it compared against the HD 7850. The same thing will probably happen with the GTX 650 as this one will most likely end up close to the HD 7770 but Nvidia slides put it against the HD 7750.

The slides show a set of games and in some cases the GTX 660 is anywhere between 15 and 60 percent faster than the HD 7850. Of course, the GTX 660 will not match the HD 7850 US $199.99 price tag and will most likely end up closer to the US $239.99 HD 7870 price tag so this comparison is rather useless. The same thing goes for the GTX 650, which ends up anywhere between 8 and 35 faster than the Radeon HD 7750 in a set of game benchmarks, but we honestly doubt that we will see it selling at US $99.99 Radeon HD 7750 price tag but rather somewhere closer to the US $119.99 Radeon HD 7770 price tag.

Of course, the prices of the upcoming GTX 660 and the GTX 650 graphics cards are not carved in stone and Nvidia can adjust them just a day before the launch so we will simply have to wait for September 13th.
