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.

Simulated Application Performance

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.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
