Intel Core i7-875K and i5-655K Unlocked

As we've mentioned, Intel's new K series unlocked processors are virtually identical to their locked counterparts. For the sake of making some quick comparisons though, we ran the new Core i5-655K and i7-875K through Futuremark’s latest system performance metric, PCMark Vantage. PCMark Vantage runs through a host of different usage scenarios to simulate different types of workloads including High Definition TV and movie playback and manipulation, gaming, image editing and manipulation, music compression, communications, and productivity.  Most of the tests are multi-threaded as well, so the tests can exploit the additional resources offered by a dual or quad-core CPU.

As you can see, at their default settings, the new Core i5-655K and i7-875K processor perform just like their locker counterparts. We didn't have a Core i5-650 at our disposal, but in comparison to the i5-661--which has a 133MHz frequency advantage--the new Core i5-655K performs right in-line with expectations. The comparison between the i7-870 and i7-875K, however, is straight-up apples-to-apples, however, and both chips perform at what are essentially identical levels.
