Here is where the keyword gets interesting. While the Mali-450 is objectively hotter, the Mali-G31 MP2 can feel warm in your hand faster. Why? Physics.
Verdict on sensation: Old Mali-450 phones get internally scalding. New G31 phones feel externally lukewarm.
The Mali-G31 MP2 is the superior GPU by every modern metric. While the Mali-450 MP6 has higher theoretical throughput, it is an architectural dinosaur that wastes energy as heat.
When you see a phone with a Mali-450 getting "hot," it isn't a sign of power; it is a sign of inefficiency. The Mali-G31 MP2 proves that architecture matters more than core count. It delivers the same (or better) frames while staying cool enough to hold in your palm.
The Winner: Mali-G31 MP2, by a cool margin.
The Mali-G31 MP2 is significantly better than the Mali-450 for modern Android boxes and budget devices, offering far superior software compatibility, energy efficiency, and thermal stability. While the Mali-450 was a powerhouse in 2013, it is now obsolete for modern apps that require newer graphics standards.
Mali-G31 MP2 vs. Mali-450: Why Architecture Beats Raw Core Counts
If you're hunting for a budget Android TV box, you’ve likely seen two names pop up constantly: the older Mali-450 and the newer Mali-G31 MP2. On paper, a "quad-core" Mali-450 might sound faster than a "dual-core" G31, but in the real world, the newer chip wins by a landslide. malig31 mp2 vs mali450 hot
Here is why the Mali-G31 MP2 is the clear choice for a "cool" and snappy experience. 1. Modern Architecture: Bifrost vs. Utgard The biggest difference is the "engine" under the hood.
Mali-G31 MP2: Built on the Bifrost architecture, the same tech found in high-end flagship chips from just a few years ago. It uses unified shaders, meaning it handles complex modern graphics much more efficiently.
Mali-450: Built on the ancient Utgard architecture (dating back to 2013). It uses a split-shader design that is far less capable of handling today's apps and 4K interfaces. 2. API Support: The "Will it Run?" Factor Software compatibility is where the Mali-450 fails.
Vulkan & OpenGL ES 3.2: The Mali-G31 MP2 supports these modern APIs, which are required for many current games and streaming apps to run smoothly.
Legacy Only: The Mali-450 is capped at OpenGL ES 2.0. This means many modern apps won't even launch, and those that do often run on "hacked" drivers that lead to freezes and crashes. 3. Thermal Efficiency: Why Older Boxes Get "Hot"
Heat is the enemy of performance. When a chip gets too hot, it slows down (thermal throttling).
Efficiency: The Mali-G31 is designed for ultra-efficiency in low-cost devices. It provides more performance per watt, meaning it stays cooler even during long 4K streaming sessions. Here is where the keyword gets interesting
The Heat Issue: 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
While you might find a Mali-450 box for a few dollars less, the experience is rarely worth it. Users frequently report that Mali-450 devices are "slow and buggy," freezing constantly compared to the "snappy" performance of Mali-G31 devices.
If you want a device that supports modern apps, runs 4K content without overheating, and won't crash when you open a menu, stick with the Mali-G31 MP2.
Are you comparing specific TV box models like the X96Q or T95? Let me know the chipset (SoC) names, and I can tell you which one has better cooling! Mali-G31 | Ultra-Efficient GPU for Low-Cost Devices - Arm
If you’ve ever used a budget smartphone or TV box from the mid-2010s to early 2020s, you’ve met one of these GPUs. The Mali-450 MP4 is the aging warhorse. The Mali-G31 MP2 is the efficient modern upstart.
But the keyword here is "hot" — both literally (thermal output) and figuratively (performance under pressure). Which one runs hotter, and which one throttles first?
If you are shopping for a cheap phone and your priority is "I don't want a hot phone," here is the golden rule: Verdict on sensation: Old Mali-450 phones get internally
Avoid any SoC containing Mali-450. This includes:
Seek out SoCs with Mali-G31 MP2. This includes:
| GPU | Idle Temp (Chip) | 30 Min Gaming (Chip) | External Temp (Back Glass) | Power Draw | | :--- | :--- | :--- | :--- | :--- | | Mali-450 MP4 | 45°C | 92°C (Throttling) | 38°C (Plastic) | 1.8W | | Mali-G31 MP2 | 35°C | 68°C (Stable) | 42°C (Glass/Metal) | 0.9W |
The most significant difference for developers is Application Programming Interface (API) support.
| Scenario | Mali-450 MP4 | Mali-G31 MP2 | |----------|--------------|---------------| | 30-min gaming, 28nm | 72°C, heavy throttle, frame drops | 58°C, mild throttle, more stable FPS | | 4K video decode + UI | Not really (no 4K HEVC support) | Handles with ease | | Emulation (PSP, N64) | Hot and stuttery | Warm but smoother | | Power draw (peak) | ~1.5W | ~1.0W |
If you are shopping for a used or budget phone today, this battle is already decided.
