Malig31 Mp2 Vs Mali450 Hot Info

Thermal Showdown: MALI-G31 MP2 vs. MALI-450 – Which GPU Runs Hotter?

In the world of budget mobile processors, two graphics processing units (GPUs) have dominated the entry-level segment for years: ARM’s Mali-450 (a veteran from the mid-2010s) and the Mali-G31 MP2 (a more modern, efficiency-focused design). If you have searched for "malig31 mp2 vs mali450 hot" , you are likely experiencing a very real problem: Your phone or tablet is heating up like a hand warmer, and you want to know which chip is the culprit.

Is the older Mali-450 a ticking thermal time bomb? Or does the newer G31 run just as hot despite being more advanced? Let’s break down the architecture, heat generation, power draw, and real-world performance to settle this thermal debate once and for all.

The Heat Generation

Winner: Mali-G31 MP2 runs cooler

Despite being "newer," the G31 was designed for power efficiency. On the same 28nm process, the G31 consumes roughly 30-40% less power than a Mali-450 MP4 at equivalent clock speeds.

Why? The 450 uses an older, wider, less power-gated design. Its four cores (in MP4 config) are not "shader cores" as we think today — they are simpler, but they leak more current. In a typical 28nm TV box (e.g., Rockchip RK3229 with Mali-450), the GPU can hit 65-75°C under load without active cooling. malig31 mp2 vs mali450 hot

The G31 MP2 (e.g., in Unisoc SC9863A or MediaTek MT8168) stays around 50-60°C in similar conditions, even with two cores running at higher frequencies.

At first glance, the older Mali-450 MP6 looks superior. It has more cores and a higher pixel fill rate. If you only look at "Gigahertz and cores," the Mali-450 wins. But this is a trap.

2. Lower Efficiency per Core

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. Mali-450 MP2: Manufactured on older process nodes (often

4. Thermal and Power Characteristics ("Hot" Factors)

The user query mentions "hot."

  • Mali-450 MP2: Manufactured on older process nodes (often 40nm or 28nm). To achieve competitive performance, it often had to run at high clock frequencies (500MHz–700MHz). This resulted in higher power consumption and thermal output relative to its performance.
  • Mali-G31 MP2: Typically manufactured on 28nm, 14nm, or 12nm nodes. The Bifrost architecture is designed for energy efficiency. While a G31 MP2 can get hot under heavy load (like gaming), it generally delivers higher FPS per watt compared to the older Mali-450.
