The new 2018 Macbooks are barely a week and we already have a problem. No, it is not the keyboard, because that is fixed without the problem by name . Nice. However, there is another, more specific problem. If you have just ordered a 2018 Macbook Pro you just have to panic if you have ordered the extra expensive 15 inch i9 model, or you must happen to be planning to take the thing to very cold places.
What turns out? The i9 processor generates more heat than the laptop can possibly drain. This not only ensures that the laptop is structurally more than 40 degrees with average temperature, but also that the processor is not burning, the so-called thermal throttling. This is a system that is useful in itself and is meant to protect a processor against temporary failure or unforeseen circumstances and heat. However, it becomes a problem if your laptop is already so hot right out of the box that the processor resets itself to a lower level than the processor that is a few hundred euros cheaper. Precisely: the i9 performs in the base less than the i7.

YouTuber Dave Lee specializes in laptops and viewing their specifications. To get the real performance of an i9 Macbook Pro out of it he was forced to put the device in a freezer (of course with the door open of course). Only in that circumstance did the i9 reach the promised speed of 2.9 GHz and he noticed that tasks were actually faster than on a comparable i7 Macbook Pro. That is pretty bizarre, so you would say that it is a one-time experience of one person and that this can not be a structural problem.
You would say that were it not that different users on forums have the same complaints (and ‘solutions’), where most people simply choose to send the Core i9 back to Apple and take an i7 in front of it. The reasoning is simple: if the problem is already so great, it will only get worse in the next few years. Long story short: do not do that, Core i9. In any case not until Apple has an ‘improvement’ that may solve the problem.
