OverclockingThe overclocking results listed in this section were achieved with the default fan and voltage settings as defined in the VGA BIOS. Please note that every single sample overclocks differently which is why our results here can only serve as a guideline for what you can expect from your card.
The maximum stable clocks of our card are 1155 MHz core (8% overclock) and 1700 MHz memory (11% overclock).
In terms of absolute GPU overclock potential, the ASUS card does better than any GTX 660 we tested today, but the MSI card reaches higher performance levels with lower clock due to some BIOS optimization by MSI.
|Maximum Overclock Comparison|
|Max. GPU Clock||Max. Memory Clock||Max. OC Perf.|
|ASUS GTX 660 DC II TOP||1155 MHz||1700 MHz||58.5 FPS|
|MSI GTX 660 TF III||1115 MHz||1750 MHz||59.7 FPS|
|ZOTAC GTX 660||1110 MHz||1730 MHz||54.5 FPS|
|Gigabyte GTX 660 OC||1125 MHz||1680 MHz||57.8 FPS|
|HD 7870||1205 MHz||1520 MHz||59.6 FPS|
Important: Each GPU (including each GPU of the same make and model) will
overclock slightly differently based on random production variances. This table
just serves to provide a list of typical overclocks for similar cards, determined
during TPU review.
Overclocked PerformanceUsing these clock frequencies, we ran a quick test of Battlefield 3 to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 9.1%.
