The next of Intel’s enthusiast level announcements this week is more like a reach into history. For enthusiasts who were present during the Core2Duo days, it was common enough to see or hear certain CPUs overclock to almost double their frequency and perhaps beyond on a good air or water cooler. After Core2Duo and Nehalem/Clarkdale CPUs Intel started to restrict the overclocking capabilities of the lower end CPUs, such that the only models that would overclock properly were the ones higher up the chain, or what we now call the ‘K’ SKUs. These SKUs cost the most, but are the highest binned parts (they have the better voltage/power characteristics) with the most amount of L3 cache and extra features such as AVX and so on.
