Test suggests 2018 MacBook Pro can not keep up with the thermal demands of the Intel Core i9 chip




Technology-centered creator Dave Lee claims the thermal design of Apple's newest 15-inch MacBook Pro does not provide sufficient Cooling for Intel's Core i9 processor, which throttles performance to prevent serious damage.

Intel's 2.9GHz Core i9 Core Core processor with Turbo Boost up to 4.8GHz will be available as a premium option for $ 300 on the 201

8's 15-inch MacBook Pro with Apple's Touch Bar Lee says the chip can not reach its full potential due to the design of the laptop.

In a video he posted on his YouTube channel Tuesday, Lee shows the flagship model of the MacBook Pro, running Adobe Premiere Pro at surprisingly low clock speeds. Tests led to the average clock being around 2.2 GHz, well below the announced 2.9 GHz.

Lee suggests that the MacBook's cooling solution, an Apple-designed heatsink and fan module, is not enough for powerful Intel silicon.

"This i9 in this MacBook can not even maintain the basic clock speed," said Lee. "Forget turbos and all that stuff, it can not even hold the base clock at 2.9 GHz, which is absurd, this CPU is a non-locked, overclockable chip, but all that CPU potential is wasted in this case or more Thermal solution that's in here. "

After Lee got the theory home, he cites the render times of Premiere Pro, showing that last year's MacBook Pro with Core i7 can chew on a 5K clip in 35 minutes Core i9 chip about four minutes. Both MacBooks are shredded by a Windows laptop, Gigabyte Aero 15X, which renders the same clip in just over 7 minutes.

Lee illustrated the obvious thermal handicap by doing the same test with the 2018 MacBook Pro in a freezer and reducing render time to 27 minutes.

It should be noted that Premiere Pro is not optimized for Mac, as the performance of the Aero 15X shows. Lee could not test the rendering speed with Apple's Final Cut Pro X or any other app.

While thermal throttling, especially in portable devices, is nothing new, Lee's results are somewhat questionable, as assumptions are made based on the performance of a single machine with a non-optimized app. To make blanket statements without thorough testing is, at best, inconsiderate and in the worst case insincere.

While Lee could not turn to Apple to comment, it is highly unlikely that the company would deliver a flagship product without rigorously testing its performance first. That's twice as much as a MacBook Pro device, considering how much the company serves the professional market.
