Our review of the 3.0GHz 8-core Mac Pro has the details on the design, features, and usability of the Mac Pro. The new Mac Pro also comes with dual gigabit ethernet ports and 802.11ac wireless networking. The Mac Pro relies on six Thunderbolt 2 ports and four USB 3.0 ports for additional storage and other devices. It has the same amount of internal flash storage as a laptop and no available PCI slots for expansion cards.

Here's another side-by-side test from a different YouTube user.While Apple offers two stock configurations, the new Mac Pro is really meant to be customized at the time of purchase.

Such as this one, depicting the system's Core-i9 CPU throttling all the way down to 800MHz in a Prime95 test. However, more reports from various 2018 MBPr users are surfacing that back up Dave Lee's claims. Maybe the CPU is defective or this is simply a malfunctioning unit that isn't cooling as it's designed to. You're arguing that this is just an isolated incident. While Premiere Pro isn't necessarily optimized for MacOS, that is a considerable difference. Then again, a similar Windows system - Gigabyte's Aero 15x laptop - renders the file in just over 7 minutes. Both graphics cards and CPUs will scale back performance after heating a certain temperature to reduce heat and prevent damage. The MacBook Pro has a very thin unibody chassis, and it likely can't offer adequate cooling and heat dissipation to support a 6-core beast like Intel's 8950HK. To be clear this is not a knock against Intel but rather against Apple's thermal solution.
