Maybe you missed it? Best Single Board Computers 2021/2 – RPi Alternatives
Radxa team has just announced their latest SBC named ROCK 3 powered with a brand Rockchip RK3568 chip. The new hardware also includes a few improvements, such as DDR4 memory and QC/PD power support. In Comparison to the previous Rockchip RK3399, its new CPU can reach up to 2GHZ, plus the GPU is faster than the ARM Mali-T860 MP4, capable of reaching up to a respectful higher frequency of 800-950 MHz.
ROCK 3A is simply an improved version of ROCK Pi 4 with some performance enhancements as well as additional new interfaces.

WIFI 6 Support
Radaxa team added an additional M.2 slot with PCIe to ROCK 3A board, so you can basically attach one NVMe SSD and another M.2 module such as a WIFI 6 M.2 card.
The ROCK 3A features an M key socket that supports two PCIe 3.0 lanes for NVMe SSDs and an E key with a single PCIe 2.0 lane. You also have all the typical I/O interfaces you expect from a standard SBC, which include an HDMI port, four USB ports, Gigabit Ethernet, and a compatible Raspberry Pi 40-pin GPIO header.
