The graphics cards are listed in the diagrams in the order of descending retail price. The results of the Zotac GeForce GTX 660 2GB are in green. Red is the color of the Sapphire Radeon HD 7870 2GB. Blue is for the EVGA GeForce GTX 660 Ti Super Clocked 2GB. Let’s get started!
The new GeForce GTX 660 is ahead of its main rival Radeon HD 7870 GHz Edition in the first synthetic benchmark, but falls behind it when both are overclocked. Notwithstanding its higher GPU clock rate, the GTX 660 is slower than the GeForce GTX 660 Ti by 14 to 15%.
The newer version of 3DMark shows us the same standings:
Unigine Heaven Demo
The GeForce GTX 660 is ahead of the Radeon HD 7870 GHz Edition when we don’t use antialiasing. But when we enable 8x MSAA, the AMD-based card goes ahead. The gap isn’t large, though. The new GeForce GTX 660 is 10 to 20% behind its Ti cousin but can overtake the latter when overclocked.
S.T.A.L.K.E.R.: Call of Pripyat
The Radeon HD 7870 GHz Edition looks preferable in the first game on our list. The GeForce GTX 660 lags behind in each test mode and is also up to 26% slower than the GeForce GTX 660 Ti. Overclocking can't help bridge the gap, either.
Metro 2033: The Last Refuge
Mainstream graphics cards are generally very slow in Metro 2033: The Last Refuge, yet we can note that the Radeon HD 7870 GHz Edition is faster than the others. This is one of the two games where the difference between the GeForce GTX 660 and GTX 660 Ti is no larger than 5%.
Just Cause 2
The GeForce GTX 660 is ahead of the Radeon HD 7870 GHz Edition when antialiasing is on, but falls behind when antialiasing is off. It is also 13 to 25% behind the GeForce GTX 660 Ti but the gap shrinks to 4 to 19% when the new card is overclocked.
