And when we looking at Core i5 8300H and Core i7 8500U, they all comes with 4 Cores and 8 Threads, so that means they might be able to beat i7 7700HQ CPU in some benchmarks. When we take a look on below table, we could see that the 8th Gen Core i9 and Core i7 all comes with 6 Cores 12 Threads architecture, that means the performance boost might be able up to 40%~50% on some benchmarks because of 2 more Cores and 4 more Threads compared to Core i7 7700HQ. The Big Difference from CPU Cores and TDPs

If you got other brand's models, the performance gap might be smaller due to lower power supply and cheaper cooling system. Platform compared to previous generations, also got confused in-between H series and U series, so here I would like to help you to clarify these CPU info, and then we could go for the real benchmark status to find out why they got big difference! We used GT75, GS65, and previous GP62 to be the test platform conditions. Intel launched the latest 8th Gen mobile CPU platform in early April 2018, but most of the users did not know the big difference from 8th Gen.

~These comparison tests based on MSI gaming notebooks with powerful cooling system, not every notebooks could have this performance boost depends on poor cooling design~
