French overclocker Radi has just posted two submissions that are Global 1st Places for Wprime 32M and Wprime 1024M using an unlocked AMD Phenom II X4 960T, a processor that first appeared in late 2010 that included hidden cores that could, with some luck and a sense of adventure, become five core, or penta-core chips.
Yesterday Radi managed to get an unlocked, penta-core Phenom II X4 960T to hit a massive 6,383MHz (+112.77%) to break the 5x CPU Global 1st Place on Wprime 1024M with a run of 2min 26sec 578ms. Clearly not satisfied with this he pushed it even further to hit 6,550MHz (+118.33%) and complete a 32M run in just 4sec 547ms. Well done Radi!
Of course the cool thing about these chips is that they were in fact derived from octa-core chips that had one or more cores damaged or faulty upon manufacture. AMD simply switched off the cores that were not fully formed and sold the resulting processors as a quad core chips. Of course the beauty from an overclocking perspective was that the application of a little guile allowed you to turn a quad core chip into a penta-core chip. Free cores equals free performance – the cornerstone of overclocking.
Just as a side note: We’re all familiar with quad-core CPUs, octa-core CPUs and will soon become acquainted with deca-core processors too, but to come across a five-core chip today head somewhat. I’m going out on a limb to describe the CPU used by Radi as a penta-core CPU – the only prefix I can think of that is remotely applicable. If you disagree or have any contradictory thoughts, chime in below.
