If you are experiencing overheating, here is how the two GPUs behave in common games that cause the "hot" search query:
: The Mali-G31 MP2 is designed for "cost-constrained" and "low-power" devices. Because it is more efficient (Bifrost vs. Utgard), it generally generates less heat for the same amount of work compared to the Mali-450. malig31 mp2 vs mali450 hot
: The Mali-G31 features integrated Arm Frame Buffer Compression (AFBC) , which drastically reduces memory bandwidth and energy usage compared to older designs. If you are experiencing overheating, here is how
ARM Mali-G31 MP2 is significantly better than the ARM Mali-450 : The Mali-G31 features integrated Arm Frame Buffer
Older Mali-450 boxes (like those using the RK3318 chip) often struggle with heat because the architecture has to work much harder (and use more power) to process modern high-resolution content. This leads to the "hot" box syndrome where the device becomes sluggish or unresponsive after an hour of use. The Verdict: Don't Buy the "Old" Tech
: Even as an entry-level GPU, the G31's support for modern APIs ensures it remains functional with current Android versions.
