The Core i7-8750H offers the biggest leap in performance that the 45 W HQ-Series has seen in years. Its CineBench R15 Multi-Thread score of 1168 points is just 15 percent slower than a stock Core i7-8700K. Actual performance, however, will be highly dependent on the overarching cooling solution as we are able to record a score as low as 966 points on a pre-production MSI GS65 sample.
