In the budget smartphone arena, two names have dominated the entry-level landscape for years: the Mali-G31 MP2 and the Mali-450 MP4/MP6. While the numbers and letters may look like alphabet soup, these two GPU architectures represent a fascinating clash of generations. One is a modern, energy-efficient building block; the other is a legendary, power-hungry warhorse that often leaves users searching for "why is my phone hot" on Google.
If you have ever gamed on a sub-$150 phone, you have likely experienced both. But which one is actually better? Is the "hot" operating temperature of the Mali-450 a sign of raw power or poor engineering? Let's dissect the benchmarks, thermals, and real-world performance.
Because the G31 is usually paired with SoCs like the Unisoc T606 or MediaTek Helio G35, the peak temperature is easier to manage. You can game for 45 minutes on a G31 device before you even feel warmth, whereas a Mali-450 device gets hot in 5 minutes.
This paper compares two distinct generations of ARM Midgard/Utgard architecture GPUs often found in the System-on-Chip (SoC) market for embedded and consumer electronics. The Mali-450 MP2, a legacy "Utgard" architecture GPU, is compared against the Mali-G31 MP2, a modern "Bifrost" architecture GPU. The analysis focuses on architectural efficiency, API support, and performance per megahertz.

Based on the search term, you are likely looking for a comparison or a technical paper analyzing the performance differences between the ARM Mali-450 MP series (specifically the MP2 dual-core variant) and the Mali-31x series (specifically the Mali-31 or Mali-450 MP2 compared to the Mali-G31 or older Utgard architectures). In the budget smartphone arena, two names have
However, the term "malig31" suggests you might be referring to the Mali-G31 MP2, which is a very common modern comparison against the older Mali-450 MP2.
Here is a technical breakdown and "mini-paper" regarding the comparison between these two GPU architectures, focusing on the Mali-450 MP2 vs the Mali-G31 MP2 (the most likely intended comparison).
The Mali-450 uses scalar execution units. To match the performance of modern GPUs, it requires many cores (MP4, MP6, MP8). More cores physically active means more silicon area wasted as heat. An 8-core Mali-450 can easily draw 1.5W to 2.5W under load, which in a cheap plastic phone with no heat pipe feels like a hot coal.
Before we declare a winner, you must understand why a GPU gets hot. Heat in a chip is a byproduct of electrical resistance (leakage current) and switching frequency (clock speed). Generally: More transistors switching faster = More heat.
