Rockchip Electronics (Rockchip) is a well-known chip manufacturer, and its processors are widely used in various smart devices. The RK3588, RK3399Pro, and RK3568 are several processors from Rockchip with different positioning, each having distinct technical parameters and application scenarios. Here is an overview of the parameters comparison for these three processors:

RK3588:

- Features an 8nm process with a CPU architecture that includes four Cortex-A76 and four Cortex-A55 cores.

- Integrates an ARM Mali-G610 MC4 GPU, supporting OpenGL ES 1.1/2.0/3.2, OpenCL 2.2, and Vulkan 1.2.

- Equipped with an NPU offering 6TOPS of computing power, supporting mixed operations of INT4/INT8/INT16/FP16.

- Supports 8K video encoding and decoding, with a maximum display output of 8K@60fps.

- Provides a rich set of display interfaces, supporting multi-screen display with different content.

- Has high-speed interfaces such as PCIe3.0/PCIe2.0/SATA3.0/RGMII/TYPE-C/USB3.1/USB2.0, etc.

RK3399Pro:

- The RK3399Pro is an upgraded version of the RK3399, but specific parameter comparisons are not provided in the search results.

- The RK3399 itself uses a 28nm process and has a CPU architecture with two Cortex-A72 and four Cortex-A53 cores.

- The GPU is Mali-T860 MP4, supporting dual-screen display.

- Supports 4K video encoding and decoding.

RK3568:

- Uses a 22nm process with a CPU architecture of four Cortex-A55 cores, with a maximum frequency of up to 2.0GHz.

- The GPU is ARM Mali-G52 2EE MC2, supporting three-screen display with the same or different content.

- Built-in NPU with 1TOPS of computing power.

- Supports interfaces such as USB2.0/USB3.0/PCIE3.0/PCIE2.1/SATA3.0/QSGMII, etc.

From the comparison of parameters, the RK3588 has a clear advantage in process technology, CPU architecture, GPU, NPU performance, and video encoding and decoding capabilities, representing the latest technological achievements of Rockchip in the field of high-end application processors. The RK3399Pro, as an upgraded version of the RK3399, although its specific parameters are not detailed, is expected to have improved performance. The RK3568 is positioned in the mid-range market, where power consumption and cost-effectiveness may be its main competitive advantages.
