Rockchip RK3399 hexa-core processor with ARM Cortex A72 and A53 cores and a Mali-T860MP GPU will soon be found in TV boxes, development boards, tablets, Chromebooks, virtual reality headset and more, and is widely expected to offer a significant performance boost against previous Rockchip processors, including RK3288, and outperform SoCs from competitors like Amlogic and Allwinner.
We can have a first clue about the performance as Rockchip RK3399 boxes and one tablet are now showing up on GeekBench.
The box is clocked at 1512 MHz, while the tablet is limited to 1416 MHz, but overall single-core score is about 1350 points, while multi-core score hovers around 2,550 points. I’m not that familiar with GeekBench so number don’t tell me anything. Let’s compare it against RK3288 which CPU-wise is the fastest processor I known of from Chinese silicon vendors targeting TV boxes.
There’s a significant single-core performance boost (+73%), and lower multi-core delta (+30%) as expected since RK3399 has 2 fast Cortex A72 cores, 4 low power Cortex-A53 cores, against 4 fast Cortex-A17 cores for RK3288. If you look into the details AES is over 10 times faster on RK3399, so there must be some special instructions used here, or AES hardware acceleration.
Rockchip RK3399 “reference” TV box also has 4GB RAM, so I’m expecting RK3399 devices to come with 2 and 4 GB versions.
Rockchip RK3399 is also faster than Nvidia Tegra K1 quad core Cortex A15 @ 2.2 GHz for single thread performance, and about equivalent for multi-core tests.
[Update: I also found GFXBench 3D graphics results for RK3399, and compared it to Nvidia Tegra K1.
The Mali-T860MP used in RK3399 is still far from the performance delivered by the Kepler GPU in Tegra K1.
Now if I compare the results to RK3288 (Mali-T764 GPU) based Ugoos UT3s TV box, the score on RK3399 (Mali-T860MP4) is also lower.
We’ll have to wait and see here, as we don’t know at which frequency the GPU is running. Both GPUs are supposed to have the same performance according to Wikipedia.]
