Rockchip RK3588 datasheet available, SBC’s coming soon

We had most Rockchip RK3588 specifications so far for the long-awaited Cortex-A76/Cortex-A55 processor, but at today’s Rockchip Developer Conference 2021, more information surfaces with impressive CPU and GPU benchmarks, and the Rockchip RK3588 datasheet has just dropped from the sky directly into my laptop, as such document usually does. At least two single board computers are expected to soon follow from Radxa and Pine64.

  • PCIe – PCIe 3.0 up to 8 Gbps (1x 4-lane, or 2x 2-lane, or 4x 1-lane, or 1x 2-lane + 2x 1-lane
  • 3x Combo PIPE PHY interfaces
    • Combo PIPE PHY0/1 – SATA III or PCIe2.1 up to 5 Gbps
    • Combo PIPE PHY2  – SATA III, PCIe 2.1, or USB 3.0
  • Low-speed I/O – 5x SPI, 9x I2C, 10x UART, GPIOs, 12-bit ADC (SARADC)
  • Package – FCBGA1088L; 21.45 x 21.45mm
  • Manufacturing process – 8nm LP

There are additional details in the datasheet, including three Cortex-M0 MCUs for the PMU, NPU, and “PD_CENTER” with the latter related to the DDR memory controller. Rockchip RK3588 has several multiplex interfaces for SATA, PCIe 2.1, USB 3.0 in a way that looks similar to Rockchip RK3568.

I’m quite surprised they could use a Mali-G610 “sub-premium premium” GPU as it was announced together with Cortex-A510, Cortex-A710, Cortex-X2 Armv9 cores, but it also works in SoCs with older Armv8 cores so that’s good, and that’s why GPU performance is truly a big step, up to over 10 times faster, compared to Rockchip RK3399.

Pine64, Radxa Rockchip RK3588 SBC’s coming soon

The other good news is that Pine64 is working on an RK3588 SBC and Radxa ROCK5 is also under development, and there should be an announcement before the end of the year. It won’t mean the boards are ready to ship, but rather pre-orders for at least one of the boards will be opened, and early backers should be happy for the prices that are going to be offered. I’ve heard both boards may be showcased at RDC 2021 tomorrow, but this remains to be confirmed. I’ve also been told Rockchip RK3588 chip is really complex, and software support will take time.
