ZOTAC GeForce GTX 670 AMP! Edition 2 GB 4

ZOTAC GeForce GTX 670 AMP! Edition 2 GB Review

Temperatures & Clock Profiles »


The overclocks 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, that's why our results here can only serve as a guideline for what you can expect from your card.

Maximum stable clocks of our card are 1150 MHz core (5% overclock) and 1890 MHz Memory (14% overclock).

Overclocking potential on ZOTAC's latest card is a bit higher than on the other GTX 670 cards tested today. This is probably because ZOTAC is reusing the more advanced PCB from their GTX 680 AMP! Edition, but this comes at higher cost, too.

Memory overclocking works very well too, ending just 5 MHz below the GTX 680 AMP Edition's 1895 MHz which set a new memory clock record here at TPU.

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,
reached during TPU review.

Overclocked Performance

Using these clock frequencies we ran a quick test of Battlefield 3 to evaluate the gains from overclocking.

Actual 3D performance gained from overclocking is 7.7%.
