Thanks to the extra couple of cores in the mid-range Sandy Bridge E chip, it takes a lead in the multi-threaded Cinebench rendering and X264 encoding tests.

But compared with the Core i7-3830K, you won’t see much of a difference in single-threaded applications: Both chips scored the same (1.53) in the CineBench R11.5 single-core test, showing where you can save money if you don’t heavily depend on highly threaded programs.

Passmark

The GPU Score seems to be GPU limited at around 61,000 3DMarks since we didn't see much of a gain on the FPS in the game benchmarks.
