Last week, Apple released a patch that would fix a bug on 2018 MacBook Pros that caused excessive throttling while the machine was busy with system intensive tasks.
The bug affected all new 2018 MacBook Pro laptops, but after being patched, most devices showed promise of far more efficient and speedy performance.
The issue was first brought to the public’s attention when YouTube tech personality, Dave Lee, demonstrated the heat and throttling issues in a video. When this and more reports came in of heat issues leading to throttled performance, Apple quickly determined that it was due to a simple software bug.
Something in the software was preventing the fans from coming on as often as they were supposed to, dropping CPU clock speed when internal temperatures spiked and leading to slower performance than older models with less-advanced Core i7 processors. Apple promptly got to work on a patch that would rectify the situation and partnered up with Lee to run additional tests.
According to a report by CNET, after installing the patch, the CPU throttling stopped and the clock frequency of the CPU and internal system temperature remained fairly stable, even during intensive tasks like encoding 4k video or playing a game set to maximum detail settings.
Lee confirmed in a Cult of Mac report that MBP fans actually come on, increasing performance on the i9. He also found that the 2018 i9 model was now 30-35% faster than the 2017 i7 model, that the patch kept the chip from throttling itself down all the time, but also that the i9 chip still didn’t hit the ideal clock speed of around 4.5 or 5GHz.
