IT House July 2 news, Apple previously released the 13-inch MacBook Pro equipped with the latest M2 SoC at WWDC, and this notebook computer began to be available to testers a few days ago. This week, YouTuber MaxTech compared the new 13-inch M2 MacBook Pro to the older MacBook Pro with the M1 Pro SoC. Tests show that the cooling performance of the new 13-inch MacBook Pro is disappointing. he found,Camera temperature reaches 108°C with severe overheating and throttling while exporting 8K Canon RAW video. This is in stark contrast to the 14-inch M1 Pro MacBook Pro, which never experienced overheating throttling in the same test.
IT Home has learned that one of the main differences between the two laptops is the cooling system. The M2 MacBook Pro body has only one fan, while the M1 Pro MacBook Pro has two fans. According to MaxTech testing, the M2 model apparently needs a second fan as well. As mentioned, the machine reached shocking temperatures under sustained load. MaxTech tweeted,This is the highest temperature he has ever seen on a Mac, including an Intel-based Mac.
Exporting 8K Canon RAW video hit a high of 108°C, a test that stressed both the CPU and GPU. When the M2 MacBook Pro reached this temperature, the fans were spinning at a peak of 7200rpm. This means that since the fans are already doing their best to control the temperature,The system has only one way to lower the temperature: overheating and throttling. This reduces device performance, but prevents chip damage from overheating.
When overheated, the M2 immediately dropped the P core’s clock from 3200MHz to 1894MHz, the E core from 2228MHz to 1444Mhz, and the GPU from 1,393MHz to 289Mhz. Power consumption will also drop sharply, the entire package is reduced from 29.46W to only 7.31W, which also causes the temperature of the M2 chip to drop all the way to 84°C, and then climb to over 100°C. This loop repeats over and over again until the video export is complete, MaxTech says. This back-and-forth throttling resulted in a performance drop that was eventually beaten by the M1 Pro MacBook Pro,The M2 took nearly 20 minutes to export, while the M1 Pro took just over 11 minutesThe latter showed no overheating and throttling in testing.
Since the M1 Pro isn’t directly comparable to the M2, MaxTech also tested the 13-inch MacBook Pro with the M1. In the same video export test, the M1 model topped out at 94°C. While the CPU doesn’t always run at 100% speed, the GPU always runs at 100% speed. The M1 model also did not experience overheating throttling.
Need to wait for more tests to determine if this is a general issue with the M2 MacBook Pro, just looking at one test can sometimes lead to false conclusions. But the test also raised concerns about the M2-equipped MacBook Air because it’s fanless.
It is worth mentioning that previous tests found that the M2 MacBook Pro 13-inch low-end SSD hard drive was slower, with a read speed of 50% and a write speed of 30% slower than the M1 version.
