Abstract generation in progress

IT Home reported on March 12 that the YouTube channel Matt Talks Tech released a video on March 10. The test found that thanks to the new Fusion Architecture, when the Apple M5 Max chip is running at full load, its temperature is 8℃ lower than the previous-generation M4 Max.

From a hardware specifications perspective, Apple’s previous-generation M4 Max uses a 16-core CPU design (12 performance cores and 4 efficiency cores). Meanwhile, the new M5 Max has been upgraded to an 18-core configuration, including 6 Super cores and 12 performance cores.

It is worth noting that inside the M5 Max, the new “performance” cores run at frequencies even higher than the efficiency cores of the M4 Max. Despite this, the M5 Max not only outperforms its predecessor in benchmarks, but also achieves a lower operating temperature.

Under Cinebench extreme load, the temperature reported by the sensors of the M4 Max reaches as high as 113℃, while the temperature on the chassis surface reaches 48.7℃. By comparison, the maximum sensor temperature of the M5 Max drops to 105℃, and the surface temperature on the chassis also falls to 46℃. Although the M5 Max’s operating temperature is still above the boiling point of water, it is indeed cooler by 8℃ than the M4 Max. IT Home has included the related images below:
