RK3288 is a 32-bit chip The flagship chip of the older generation of RK.

The RK3399 is a 64-bit chip The flagship chip of the new generation.

It has a peak speed of 326glops, a pixel fill rate per second, and support for OpenGL and Renderscript

On April 13, 2014, the Hong Kong Spring Electronics Fair kicked off, and the domestic first-line chip manufacturer Rockchip carried the ** processor RK3288 to be exhibited in Hall 1 of the Hong Kong Convention and Exhibition Center in Wan Chai. RK3288 combines a variety of advantages, and is the world's first ARM core chip with a new architecture, the world's first chip with the latest Mali-T76X series GPU, and the world's first chip with 4kx2K hardware decoding.

Rockchip RK3368 adopts an octa-core 64-bit ARM CoreTex-A53 core architecture, 28nm process design, and the main frequency is; The GPU is PowerVR G6110 and supports OpenGL ES; RK3368** is super capable, supporting 4K 2K**, hardware decoding and HDMI output; The system platform is Android lollipop; Support Security OS and mainstream DRM and security standards; Antutu ran more than 38,000 points.

Cortex-A53 is the high-end product of ARM's latest 64-bit ARMv8 architecture-based Cortex-A50 processor family, which is the world's most energy-efficient and smallest 64-bit processor, with high performance and low power consumption. The octa-core Cortex-A53 can operate at full speed at high loads, and can also flexibly shut down cores and reduce frequency to low-performance, low-power modes at low loads.

A 64-bit environment that doubles the width of the processor's data stream and supports larger memory capacities, providing greater processing efficiency when processing data at scale. The Cortex-A53 also has a number of important features, such as support for virtualization, 256 TB of storage, and L1 and L2 caches with ECC support.
