We began our testing with an older boxed Core i7-3770K as we waited for the FX-8350 we purchased. Relatively certain the AMD processor would hit at least 4.4 GHz without thermal issues, we started off Intel's processor at the same clock rate. Later, it became clear that our estimate was too conservative, as both CPUs exceeded 4.5 GHz at our chosen voltage levels.
Retesting at higher frequencies would have further delayed this story, so we stuck with 4.4 GHz on both the Intel and AMD chips, at least in the clock-matched portion of our benchmarking.

Great performance and quick installation have kept Thermalright’s MUX-120 and Sunbeamtech’s Core Contact Freezer on my shelf for several years. The brackets that came with these older samples make them non-interchangeable, however.
G.Skill’s F3-17600CL9Q-16GBXLD has a remarkable DDR3-2200 CAS 9 rating, using Intel XMP technology for semi-automatic configuration. As a non-Intel platform, the Sabertooth 990FX configures XMP values through Asus' DOCP setting.
Seasonic’s X760 provides the consistent efficiency required to assess platform power differences.
StarCraft II doesn’t support AMD's Eyefinity technology, so I looked at the recent work of our other editors before bringing back a few classics in today’s test: Aliens vs. Predator and Metro 2033.
