MPMan MID74c review part 2: Tablet performance
Boxchip Allwinner A10 CPU vs Rockchip RK2918

Part 1: Introduction
Part 2: Tablet performance (Allwinner A10 CPU)
Part 3: multimedia and HD video playing capabilities

The MPMan MID74c tablet is powered by the Boxchip Allwinner A10 CPU running at 1 GHz assisted by an ARM Mali 400 GPU. Let’s see how these compare with another ARM Cortex A8 based tablet in the same price range, the Arnova 7 G2, equipped with a Rockchip RK2918 CPU (including a Vivante GC800 GPU).

MPMan MID74c vs Arnova 7 G2 benchmarks results

Test conditions:
- both devices were using latest firmware from the manufacturer
- all benchmarks were executed after all tasks have been killed
- test were run multiple times to check for consistent behaviour, the results shown here correspond to average values

Benchmark results interpretation

Raw numbers from these benchmarks show a clear advantage (from 5% to 30% depending on the tests) to the Boxchip Allwinner A10 CPU over the Rockchip RK2918 when both processors run at the same 1 GHz frequency. CF-Bench shows relatively similar results for both tablets in term of CPU pure processing power, the difference on the general benchmarks probably comes from other subsystems such as the memory speed and graphical processor (GPU). The single core ARM Mali 400 GPU seems to be more efficient than the Vivante GC800 integrated in the Rockchip RK2918 SOC. A quad core version of the Mali 400 GPU is included in some higher end devices such as Samsung Galaxy SII phone (Samsung Exynos 4210) and more recent Rockchip 3066 CPU.

Comparing two platforms with different versions of the operating system (Android 2.3 vs Android 4.0) isn’t an easy thing, we’ll try to update the benchmarks with the new Arnova G3 based on RK2918 running on Android 4.0 ICS.

Overclock the MPMan MID74c, Allwinner A10 CPU at 1.2 GHz

You can see at the end of the first video, the Boxchip CPU supports well overclocking to 1.2 GHz and we can see a proportional improvement of the performance for CPU related tasks, while it has almost no impact on the GPU performance. When clocked at 1.2 GHz the Boxchip CPU really surpass the RK2918 with over a 50% increase on the Total Index on Quadrant benchmark.

MPMan MID74c (at 1.2 GHz & 1 GHz) vs Arnova 7 G2: benchmarks results

	Arnova 7 G2	MPMan MID74c 1 GHz	MPMan MID74c 1.2 GHz
Quadrant Advanced v2.0 higher is faster	Total: 1325 CPU: 1299 Mem: 1181 I/O: 2264 2D: 198 3D: 1681	Total: 1723 CPU: 1401 Mem: 1501 I/O: 3684 2D: 271 3D: 1760	Total: 2076 CPU: 1685 Mem: 1615 I/O: 4912 2D: 292 3D: 1876
Neocore v 1.9.35 higher is faster	51.4 FPS	57.1 FPS	57.6 FPS

We’ve also made a specific video to see the performance on Linpack application as the CPU frequency increases from 1 GHz to 1.1 GHz, 1.2 GHz and 1.25 GHz. The system is stable up to 1.25 GHz but it freezes at higher frequencies.
