Rockchip RK2918 vs Boxchip Allwinner A10 CPU - Tablet PC Performance Comparison
Posted by admin on May 9, 2012
The FunPad FP704 tablet is powered by the Boxchip Allwinner A10 CPU running at 1.2 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).
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.
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.
