Rockchip RK3399
The RK3399 was Rockchip’s flagship before the RK3588. It has two Cortex-A72 and four Cortex-A53 cores, a Mali-T860 MP4, PCIe 2.1 x4 and two USB 3.0 Type-C ports with DisplayPort. Mainline support is mature: Panfrost handles the GPU and Hantro handles video decode. Libre Computer uses it on the Renegade Elite.
