Chinese website, padhz.com, pitched 3 quad-core processors, Rockchip’s latest flagship RK3188, Samsung’s Exynos 4412 and Nvidia’s Tegra 3 together in a battle to determine which is the best.
The Rockchip RK3188 is the successor to the very popular RK3066, a dual core ARM Cortex A9 processor. The RK3066 is widely used in many Android tablets manufactured by Chinese manufacturers due to its very good performance and low price.
It is also widely used on many of the popular dual core Android Mini PCs like the MK808, UG802, MK802 III, Neo G4, MX1 and Uhost2. It is widely expected that many of the next generation Android Mini PCs featuring quad-core processors will be using the RK3188.
Both the Exynos 4412 and the Tegra3 have been around for about a year or longer now and they both feature slightly older technology. The 4412 uses 32 nm technology while the Tegra 3 uses older 40 nm. The RK3188 features 28 nm technology. As a result, the RK3188 has a maximum 1.8 GHz clockspeed compared to 1.3 GHz on the Tegra 3 and 1.4 GHz on the Exynos 4412.
For the tests, the site used a Google Nexus 7 tablet to represent the Nvidia Tegra 3, a Ramos W42 Quad Core Android Tablet to represent the Exynos 4412 and a Cube U30GT2 Quad Core Android Tablet to represent the RK3188.
There are slight discrepancies in the hardware specifications of the 3 tablets of course. For example the Cube U30GT2 has a full HD (1920 x 1200) retina display while the other 2 tablets only have 1280 x 800 displays. The Cube U30GT2 has 2 GB RAM while the others only have 1 GB. The other significant difference is that the Nexus 7 runs on the latest Android 4.2.2 OS. The Cube U30GT2 runs on the slightly older 4.1.1 but the Ramos W42 only has Android 4.0.4.
Graphs and tables of the actual results can be found on the site but in summary, the Rockchip RK3188 is declared the winner. The RK3188 beats the other 2 contenders in almost all the tests. In tests where the RK3188 loses out, such as the speed of loading large-sized games and opening large files, the margin of difference is very small and is probably insignificant.
The only test that the RK3188 loses out significantly is in the power consumption test. The Exynos 4412 triumphs over the RK3188 and the Tegra 3. However, from the standpoint of an Android Mini PC, power consumption is not really a concern since it is not a battery-powered device.
The final result is actually not the surprising considering that the RK3188 was just released early this year. What would be more revealing is how the RK3188 performs compared to newer quad-core processors like the Allwinner A31 or the Nvidia Tegra 4.
