Benchmark: 3DMark 11
3DMark 11 is the latest version of this hugely-popular synthetic benchmark. Making use of DX11 features such as tessellation, compute shaders and multi-threading, it provides modern-day results and is available as a free download.
We like to think of 3DMark 11 as a best-case scenario. It typically represents what would happen in a perfect world - where's drivers and games all work in harmony - and it suggests that Gigabyte's card has a fierce backbone.
In 3DMark 11's Performance test, the heavily-overclocked GTX 660 Ti is able to breeze past a stock-clocked GTX 670, but look what happens in the Extreme test. When large amounts of image-quality enhancements are introduced, the better memory bandwidth and fillrate capabilities of the GTX 670 continue to shine through; though, the 660 Ti isn't a million miles behind.
Interesting to note, also, that 3DMark 11 suggests that the GeForce GTX 600-series is fundamentally quicker than all of the Radeon HD 7000-series cards on show. But as we know, that isn't how it pans out in various games.
