In long-term field tests that use many Core i9 processor cores, the speed drops below the base clock frequency of 2.9GHz .Tuber Dave Lee shows this in a video in which he new MacBook Pro compares with last year's model, in both cases the variants with the best specifications.

The rendering of a 5k video in 4k format takes 39 minutes and 37 seconds, while the 2017 MacBook Pro with Core i7 taking 35 minutes and 22 seconds, Lee notes that while rendering the Core i9's clock speed in the new MacBook Pro drops to 2.2 GHz due to the heat generated by the # 39; laptop.

Another video comparing you The c zollotech subway anal shows that the 2018 version of the MacBook Pro is also slower in Final Cut Pro X than the 2017 version.

In the 2017 MacBook Pro top model is the Core i7-7820HQ, a quadcore with a clock speed of 2.9 GHz and a turbo up to 3.9 GHz. The two additional cores of the i9 should be profitable especially in rendering programs. In practice, it turns out that this is not the case.

The new MacBook Pro 13 "also suffers from chokes, according to a first test of the German Notebookcheck, the version with the new Core i5-8259U, a quadcore with a PCT of 28 watts.In Cinebench the laptop in the Multi-test is not faster than laptops with the Core i5-8250U, a processor that is more efficient and has a fifteen-watt tdp. According to the processor specifications in the MacBook Pro 13 ", a higher score was expected
