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.
EVGA's card has higher clocks than a standard GeForce GTX 670 but the same number of shaders. It loses out on the backside by removing a 64-bit memory partition and eight associated ROPs. This give-and-take compromise means the card is a little slower than the second-rung 600-series GPU.
KFA²'s competing GTX 660 Ti features a larger framebuffer and a higher core frequency, helped on by a rampaging GPU Boost clock.
