The results on the diagrams are sorted out according to the recommended retail price of the tested graphics cards (from high to low). Products based on the new generation Nvidia graphics processors are marked with green, AMD products – with red, and Asus GeForce GTX 560 Ti 448 cores – with dark teal colors.
The GeForce GTX 660 Ti looks very confident in our first semi-synthetic benchmark, outperforming all of the AMD-based products at its default clock rates and stopping short of the GeForce GTX 670 when overclocked. The new card is 34-41% ahead of the old GeForce GTX 560 Ti-448. Looks like a very promising start.
The GeForce GTX 660 Ti performs even better in the newer and heavier 3DMark 2011. At its default clock rates of 928/6008 MHz, the Zotac beats both Radeon HD 7xxx cards, including the HD 7950 with new BIOS. When overclocked to 1063/7168 MHz, the Zotac is almost as fast as the GTX 670. It enjoys an advantage of 51 to 58% over the GeForce GTX 560 Ti-448.
Unigine Heaven Demo
The GeForce GTX 660 Ti is good in Unigine Heaven, especially at the easier settings. It is faster than the Radeon HD 7870 GHz Edition and equal to the reference HD 7950 at 1920x1080 with 8x antialiasing, but the updated HD 7950 with clock rates of 925/5000 MHz is ahead. Interestingly, the slightly overclocked Radeon HD 7870 GHz Edition is somewhat faster than the overclocked GeForce GTX 660 Ti in this test. The latter card must be limited by its memory bus.
S.T.A.L.K.E.R.: Call of Pripyat
The GeForce GTX 660 Ti is but slightly faster than the Radeon HD 7870 GHz Edition at the default frequencies. The Radeon HD 7950 is harder to beat, especially with the new BIOS. The GTX 660 Ti is also 31-46% ahead of the GTX 560 Ti-448 and 7-28% behind the GTX 670. It easily catches up with the GTX 670 when overclocked, though.
Metro 2033: The Last Refuge
The lack of memory bandwidth can be felt in Metro 2033: The Last Refuge. The Zotac is ahead of the Radeon HD 7870 GHz Edition with MSAA turned off, but the AMD-based card is faster with enabled MSAA. The difference isn't large, but the frame rates are low, so every frame per second counts. Take note of the colossal advantage of the GeForce GTX 660 Ti over the GTX 560 Ti-448 at the heaviest settings. The old card obviously lacks memory while the newer model's 2 gigabytes are quite enough.
Just Cause 2
Working at its default clock rates, the GeForce GTX 660 Ti delivers the same performance as the overclocked Radeon HD 7870 GHz Edition or the original Radeon HD 7950. The accelerated version of the latter card is equal to or even slightly faster than the GTX 660 Ti. And this adds points to the new card, of course. It is also 37-55% ahead of the GeForce GTX 560 Ti-448 but fails to catch up with the GeForce GTX 670 even when overclocked.
