The MateBook only ships with Core m processors, a necessity of the incredibly thin and fanless design that Huawei is using. That obviously will put the MateBook behind other tablets and notebooks that use the Core i3/i5/i7 processors, but with a power consumption advantage along the way. Honestly, the performance differences between the Core m3 and m5 and m7 parts is pretty small – all share the same 4.5 watt TDP and all have fairly low base clock speeds and high boost clocks. The Core m5-6Y54 that rests in our test sample has a base clock of 1.1 GHz and a maximum Turbo Boost clock of 2.7 GHz. The top end Core m7-6Y75 has a base of 1.2 GHz and Boost of 3.1 GHz. The secret of course is that these processors run at Turbo clocks very infrequently; only during touch interactions and when applications demand performance.
Any major computer upgrade generally requires a full software reinstall too. No so if you heed the advice in the guide to Upgrading a Motherboard without Reinstalling. PCSTATS Tips
