RK3588 is Rockchip’s best performing processor to date, likely in 2022


Chinese chipmaker Rockchip has started talking about the RK3588 octa-core processor more than two years ago, but due to a series of delays it has yet to ship.

That could change soon. The company shared detailed specifications and benchmarks for its best-performing processor to date at the Rockchip 2021 developer conference. And at least two companies plan to launch single-board computers with RK3588 processors in 2022.

The RK3588 processor feature set includes:

  • 4 ARM Cortex-A76 processor cores up to 2.6 GHz
  • 4 ARM Cortex-A55 processor cores up to 1.8 GHz
  • ARM Mali-G610 MP4 graphics card
  • NPU (Neural Processing Unit) with up to 6 TOPS of AI performance
  • Support video decoding up to 8K / 60Hz
  • Support for PCIe 3.0, USB 3.1 Gen 1 and dual Gigabit Ethernet

While those specs aren’t enough to make this processor competitive with the latest ARM-based flagship chips from Qualcomm or MediaTek, the new chip is expected to offer a major performance improvement over older Rockchip processors like the popular RK3399, a chip hexa-core found in a number of older Chromebooks, single boards, computers and even some laptops like the inexpensive Linux PineBook Pro laptop.

In tests provided to CNX-Software, RK3588 offers 2.7x single-core performance improvement in Geekbench 4 and 3.4x multi-core performance improvement. It also offers up to 6 times the graphics performance.

Pine64’s Lukasz Erecinski says the new chip brings “entry-level desktop ARM processor performance and plenty of I / O options,” and it’s likely that future single-board PCs and other products from Pine64 could use. the new chip. The upcoming Radxa Rock 5 Model B is also expected to use the RK3588 processor.
