Video Raises Concerns About Excessive Thermal Throttling On 2018 MacBook Pro With Intel Core i9

Last week, Apple announced new MacBook Pros, including a 15-inch model that supports Intel's 6-core 2.9GHz i9 processor. YouTube Dave Lee managed to get his hands on this top-of-the-line device early and run some tests, revealing that the laptop gets severely throttled due to thermal issues. 9to5Mac reports: Dave Lee this afternoon shared a new video on the Core i9 MacBook Pro he purchased, and according to his testing, the new machine is unable to maintain even its base clock speed after just a short time doing processor intensive work like video editing. "This CPU is an unlocked, overclockable chip but all of that CPU potential is wasted inside this chassis -- or more so the thermal solution that's inside here," says Lee. He goes on to share some Premiere Pro render times that suggest the new 2018 MacBook Pro with Core i9 chip underperforms compared to a 2017 model with a Core i7 chip. It took 39 minutes for the 2018 MacBook Pro to render a video that the older model was able to render in 35 minutes. Premiere Pro is not well-optimized for macOS, but the difference between the two MacBook Pro models is notable. Lee ran the same test again with the 2018 MacBook Pro in the freezer, and in cooler temperatures, the i9 chip was able to offer outstanding performance, cutting that render time down to 27 minutes and beating out the 2017 MacBook Pro.
