Overclocking

Overclocked Performance

Using these clock frequencies, we ran a quick test of Unigine Heaven to evaluate the gains from overclocking.


Actual 3D performance gained from overclocking is 4.5%.

Power Limits

All NVIDIA graphics cards have a power limit defined in the BIOS, which limits power draw by adjusting Boost frequencies accordingly. A second limit exists that defines the maximum TDP adjustment limit for user overclocking; i.e., how far the power slider will go. In the second chart, the (+xx%) value lists the percentage increase from the tested card's default power limit to the highest available manual setting—the slider's adjustment range.

While the Zotac AMP Extreme does offer the highest power limit of all RTX 4070 Ti cards that we've tested so far, these limits cannot be reached in actual usage.



Even though I've set the power limit to maximum, with Furmark running, the card is sitting in the "power limit exceeded" state, at just 303 W. This seems to be a BIOS bug, hopefully Zotac can release a fix.
