MacBook Pro 2018: a dissipation system unsuitable for the Core i9?

Ultra powerful, ultra design, ultra modern… and ultra poorly cooled. This could sum up the first feedback on Apple's new MacBook Pro, and more particularly those concerning the model equipped with a Core i9 from Intel. A series of particularly powerful processors, but which should not be entrusted to just any dissipation system if one wishes a machine capable of correctly exploiting the computing power developed by these chips.

A point that Apple has obviously not taken into account as it should have. As a result of the races, the most expensive 2018 MacBook Pro (still offered at nearly 3300 euros) heats up and fails to keep up its frequencies. Suffice to say that the inventory hurts for a device supposed to be aimed primarily at professionals.

MacBook Pro 2018: a dissipation system unsuitable for the Core i9?

The first feedback shows serious overheating problems on the latest MacBook Pro model, the most upscale versions of which are adorned with a Core i9… hot as embers.

This alarming observation for the apple company comes in particular from the American Youtubeur Dave Lee, who yesterday published a test video explicitly named “ Beware the Core i9 ” (“ Take care with the Core i9 ”, in French). A video in which the interested party highlights a number of problems encountered with the 15-inch version of the new MacBook Pro, the one animated by this famous Core i9.

Among the identified pitfalls, major performance problems, especially in video encoding. The videographer points out as well as in Adobe Premiere, the last baby of Apple quickly peaked at a frequency of 2.2 Ghz, for a temperature which still reached 96 degrees Celsius. We are far from the base frequency of the processor, normally clocked at 2.9 Ghz.

These frequencies constrained by too high a temperature (Thermal Throttling) have in this case a huge impact on the performance of the device in encoding. Dave Lee has also taken out his stopwatch for the occasion and the observation is clear: 35 minutes and 22 seconds are necessary for a 2017 MacBook Pro, powered by a Core i7, to encode a video in 4K H.264 under Premiere Pro; while the 2018 model, equipped with a Core i9, will take exactly 39 minutes and 37 seconds to perform the same task.

Proof if it were necessary that the dissipation system chosen by Apple is indeed to point the finger for these performances at half mast, the same encoding, carried out this time in a freezer, will not take more than 27 minutes and 18 seconds to new MacBook Pro i9.

Clearly, Apple will have a lot of progress to make in terms of heat dissipation if it wants to use the full power of the Santa Clara founder's Core i9s.
