News Project Cottonwood SBC Promises Double Raspberry Pi 4's Performance

Double the performance of a Pi 4 puts it squarely in the ballpark of a Rockchip RK3588S. That's my bet. And 2019 is roughly around the time Rockchip first started making noises about it - that one has been in the oven for a really long time.

Lately, Amlogic seems to have dropped out of competition with Rockchip for the high-end of the market. If anyone knows of other possible contenders, do tell.

The latest Orange Pi 5+ is in a league of its own and Armbian is a very usable operating system with hardware acceleration for its Ubuntu-based distro. Cost is very competitive with Pi4; by current SBC performance standards, Pi4 is not at all performance competitive (nor cheap / plentiful).

The 3588 is a somewhat better chip and I'd rather see that used, depending on the price difference. (The difference is an extra PCIe lane and some other I/O; the S model is a "cost-optimized", slightly cut down 3588.)

If they're using any version of the RK3588, it's definitely the "S". Considering what the Orange Pi 5's cost, it seems hard enough even to make a board with the S that has a respectable amount of RAM for the implied target price of $70.

Besides, the S-version mostly sacrifices peripherals rather than performance. If all they're trying to build is a Pi-class board, they don't need to offer the additional PCIe lanes, etc.

Fair enough. I have a Rock 5B, with the non-S version, and it's nice to have an NVMe drive, but both chips have the same cores, for example.
