Intel Core i7-875K And Core i5-655K Battle Beyond 4 GHz

Do you like the idea of an unlocked clock multiplier, but don't want to pay $1,000 for an Extreme Edition? Intel's K-series CPUs bring overclocking down to the mainstream. The question is: can these scalable parts keep up with AMD's Black Edition CPUs?

Benchmark Results: Synthetics

For the most part, Vantage paints a picture we pretty much expected to see. Mainly, the quad-core, Hyper-Threading-equipped Core i7-875K throws down the highest numbers, followed by AMD’s hexa-core Phenom II X6 1090T. The battle between the Core i5 and Phenom II X4 is surprisingly close, considering the significant clock rate disparity.

Reflecting a proclivity for threading, the 3DMark CPU scores are perhaps most interesting. There we see the Lynnfield-based processor score first, followed by the Thuban-based X6. AMD’s Deneb-based X4 snags third, followed closely by the Clarkdale-based Core i5.
