About a week ago, Apple introduced the updated MacBook Pro, which differ from its predecessors with more powerful hardware and a slightly improved keyboard. But more people were intrigued by the opportunity to purchase a MacBook Pro with an Intel Core i9-8950HK and 32 GB of RAM. However, this week it became clear that this modification is a serious drawback.
Judging by the tests a new laptop in the popular benchmark Geekbench, its performance, it significantly ahead of its predecessors – the capacity increase of multi-core test is about 40%. However, the reality is not so rosy.
According to Dave Lee, author of the eponymous Youtube channel, nominal cooling system MacBook Pro just can’t cope with “hot” Intel Core i9-8950HK. And as a result, the processor is exposed to the throttle (engine protection from overheating, leading to a marked decrease in performance).
When testing utility Prime 95 it turned out that the performance of the top processor in the new MacBook Pro starts to fall after only minutes of active use – it decreases with the standard 2.9 GHz up to 2.5 GHz. The cooling system works at maximum speed. And after 5 minutes under heavy load the CPU frequency will drop to 800 MHz.
With further testing it turned out that due to lack of cooling Intel Core i9-8950HK just can’t unleash its full potential. So, rendering a video in Premiere Pro (from 5K to 4K H. 264) is the new MacBook Pro took 39 minutes, 37 seconds. At the same time, top-end MacBook Pro 2017 coped with a similar task in 35 minutes and 22 seconds.
It is noteworthy that with the advent of cooling the new “Proshka” with an Intel Core i9 begins to work much faster. So, placing the laptop in the freezer, Dave managed to reduce the render time video with almost 40 minutes to 27 minutes 18 seconds, winning by almost 12 minutes of time.
