Apple's New Core i9 MacBook Pro Allegedly Overheats Under Load Leading to Significant Throttling [Video]

Apple's new Core i9 MacBook Pro allegedly overheats under load leading to significant throttling, according to YouTube reviewer Dave Lee.
In a video posted today, Lee says that "the MacBook Pro cannot cool the i9 properly". After a few seconds of performing an intensive task like rendering, some very serious throttling kicks in.
"This i9 in this MacBook can't even maintain the base clock speed. Forget about turbos and all that stuff, it can't maintain the 2.9GHz base clock which is absurd!"
Using benchmarks, Lee demonstrates that when rendering a clip in Premiere the previous generation MacBook was able to finish in 35m 22s. The new 2018 MacBook Pro took 39m 37s.
To demonstrate that the problem is the thermal solution in the MacBook Pro's chassis, Lee put the MacBook in the freezer and performed the render again. This time the 2018 MacBook Pro completed the render in 27m 18s, a significant improvement.
If Lee's findings are typical, this would seriously affect the Core i9 MacBook Pro's appeal to pro users.
