The new Apple MacBook Pro series is the most powerful but the chips do run pretty hot especially the core i9 model. This caused the chip to throttle. Apple knows of the issue and has apologized to the people that have gone out an bought one and have experienced such issues. Apple has released a bug fix for the issue and has promised that the thermal throttling issue will be fixed.
According to Apple, after the fix, the 15-inch Apple MacBook Pro will get an additional 70% faster and the performance of the 13-inch model will double. The following is the complete statement:
Following extensive performance testing under numerous workloads, we’ve identified that there is a missing digital key in the firmware that impacts the thermal management system and could drive clock speeds down under heavy thermal loads on the new MacBook Pro. A bug fix is included in today’s macOS High Sierra 10.13.6 Supplemental Update and is recommended. We apologize to any customer who has experienced less than optimal performance on their new systems. Customers can expect the new 15-inch MacBook Pro to be up to 70% faster, and the 13-inch MacBook Pro with Touch Bar to be up to 2X faster, as shown in the performance results on our website.
We will have to get the third-party results in order to verify if all this is indeed true. Some reported that the heating issue was due to the small form factor and the lack of air flow. If that is indeed the case then this is a cooling issue which can not be easily fixed with software. It will be interesting to see what the tests have to say and whether or not the numbers that Apple claims for the Apple MacBook Pro are true.
Apple talked about a digital key being missing and that was the cause of the problem but did not go into much detail. It will be interesting to see what kind of performance gains we will get from the said digital key. Everyone will need to re-run their tests after this update. More more news regarding the matter stay tuned.
