It appears that Intel’s newest Skylake CPU generation will be the first one to arrive with fully unlocked mobile processors, which are ready for overclocking. Up until now the company has had desktop processors with unlocked multipliers only and just a few models at that.
As of now there will be only one such chip and it might be the Core i7-6820HK processor, which is scheduled to arrive in September. There’s no information on the chip but we suspect it will have four cores with support for Hyper-Threading technology and 6 MB of L3 cache, just like other high-end Intel mobile chips. The chip will have TDP of 45W and this is for sure.
This is good news for overclockers but then the Core i7-6820HK will not be for every notebook. The most important question is whether a notebook with this CPU will have an adequate cooling solution because no matter how you look at it the i7-6820HK will emit a lot of heat when overclocked. So the whole thing goes down to one thing – if the cooler inside a notebook is good enough for both the Core i7-6820HK and overclocking or not.
