Last week, Apple unveiled new versions of its MacBook Pro laptops with new and improved features. The most notable being the introduction of new 8th Gen Intel Core processors, including Intel’s top-of-the-line Core i9 processors. However, it seems like those planning to buy the top variant of the MacBook Pro with that particular processor may have to deal with a lot of thermal throttling. 

YouTuber, Dave Lee posted a video in which he reviews the top-of-the-line 15-inch MacBook Pro with an Intel Core i9 processor that is supposed to offer a base clock speed of 2.9GHz. However, Lee notes that while the i9 is a very powerful CPU, the chassis used on the MacBook Pro is not able to cool the processor properly. He says that just after a “few seconds” of using Adobe Premier, the clock speed of the MacBook Pro dropped to an average of 2.2GHz. He compared the same to a Gigabyte Aero 15X that runs a 2.2GHz Intel i7 processor and noted that the machine could get an average clock speed of 3.1GHz thanks to Turbo Boost.

The fact that the the Intel Core i9 can’t even reach its base clock speed in the MacBook Pros chassis means that the potential of the chipset is being wasted. Lee also ran Adobe Premier while placing the machine in a freezer and noted that the rendering time went down from 39 minutes and 37 seconds, to 27 minutes and 18 seconds. Lee also adds that while other Macs as well as PCs also show signs of thermal throttling, this degree of throttling is “unacceptable”.

The new MacBook Pros are yet to be launched in India. The new MacBooks start at Rs 1,49,900 for the base, 13-inch variant, while the top-end 15-inch MacBook Pro costs Rs 1,99,900. Besides the new processors, the new Macbooks also come with a TrueTone display and a new quieter keyboard. A recent report also states that Apple Repair Centers will not be able to replace components immediately. As per the report, minor components for the new MacBook Pros will not be available until later this month, while replacement keycaps will not be available till August. Major components Like motherboards and displays may not be available till late September. So if you do buy one of the new MacBooks, you might want to exercise caution till then.
