Chinese chip maker Rockchip started talking about the RK3588 octa-core processor more than two years ago, but due to a series of delays it has yet to actually ship.
That could change soon. The company shared detailed specs and benchmark results for its highest-performance processor to date during the 2021 Rockchip Developer Conference. And at least two companies are planning to launch single-board computers with RK3588 processors in 2022.
The RK3588 processor’s feature set includes:
- 4 x ARM Cortex-A76 CPU cores at up to 2.6 GHz
- 4 x ARM Cortex-A55 CPU cores at up to 1.8 GHz
- ARM Mali-G610 MP4 graphics
- NPU (neural processing unit) with up to 6 TOPS of AI performance
- Support for up to 8K/60Hz video decoding
- Support for PCIe 3.0, USB 3.1 Gen 1, and dual Gigabit Ethernet
While those specs won’t be enough to make this processor competitive with the latest ARM-based flagship chips from Qualcomm or MediaTek, the new chip should offer a major performance boost over older Rockchip processors like the popular RK3399, a hexa-core chip found in a number of older Chromebooks, single-board, computers, and and even some laptops like the PineBook Pro low-cost Linux laptop.
In benchmarks provided to CNX-Software, the RK3588 offers a 2.7X single-core performance boost in Geekbench 4, and a 3.4X improvement in multi-core performance. It also offers up to 6X the graphics performance.
According to Pine64’s Lukasz Erecinski, the new chip brings “entry-level desktop-class ARM CPU performance and plenty of IO options,” and it’s likely that upcoming single-board computers 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.
