Orange Pi 5 (Rockchip 3588)

I just discovered this. I see one version on Amazon for $137.
I see what looks like the same thing on Aliexpress for $115.

Honestly, it looks like more than I want or need for the sort of things I do. With only 4G of ram the price drops to $68, making it quite affordable (the same price as the Pi 4). On the other hand, you can get the RK3399 Pi 4 board with 16G of eMMC, saving you from buying an SD card or an M.2 module

Also the Pi 5 (as well as the Pi 4 LTS) have a 26 pin rather than a 40 pin GPIO header.

No eMMC, but the M.2 slot on the bottom of the card could be as good or better. They say it supports "2242 NVME SSD".

Here is a 256G samsung SSD for $21:

A76 versus A72

The A72 runs pretty much twice as fast as the A53 or A55.
The A76 is faster yet -- about 35 percent faster than the A72.

This comes by having the ability to run 4 instructions per cycle, compared to 3 per cycle for the A72. It also has a bigger L1 cache. (64k instead of 32k). Some A72 run at speeds up to 2.4 Ghz, but not the RK3588.
