Overclocking and Performance

A couple critical notes before we proceed: as always, mileage will vary when overclocking, so be vigilant in monitoring temperatures and be sure to always test for stability after each incremental change. We recommend FurMark or ASUS Kombustor for stability testing as they’ll drawing more power and cause higher temperatures than your favourite game or 3DMark benchmark, so it is a worst-case scenario. Otherwise, run 3DMark Vantage or OCCT and see if it can pass a few looped tests for stability, but be sure to log and monitor the resulting temperatures.

With that out of the way, we settled in for some overclocking of the core and memory clocks and achieved the following result:

Overclocking

Interestingly, we topped out the overclocking utility before the card ran out of gas. Both Smart Doctor and MSI Afterburner capped off the core at 1000MHz, and we managed to hit that fully stable. The memory fared very well at 1164MHz. These are massive overclocks, with 29% on the core and 16% on the memory. Excellent.

After achieving this overclock, we ran a couple benchmarks to see the effect. Below are some results:

The performance increase is very impressive, as the 6850 not only crushes the GTX 460 but also surpasses the 470 as well. In fact, the 6850 matches the 6870 when overclocked; moving up an entire card model is a huge bonus without costing any extra, which bodes well for consumer value here.
