Raspberry Pi 4 PCIe bridge “chip”

The RockPro64 has an x4 PCIe slot. The 2gb model is 60$ and the 4gb one is 80$. Add ~20$ for accessories and you have a nice little board that should be faster than the RPI and has more features.

Rockchip's PCIe is kind of a joke, you can't use a GPU there because there's not enough BAR space. But yeah, you could run an NVMe drive or a big NIC, I guess.

Also, the heterogeneous 2xA72+4xA53 CPU setup is ehh.. :/ What's really cool about the RPi4 is that there's four A72 cores. And now 8GB RAM. And https://rpi4-uefi.dev.

I've put a 4-port SATA controller in mine and use it as a NAS. Haven't benchmarked it but it works well.

If it is anything like the Rock64, it will also be unstable, negating much of the benefit.

I have one that's run well for a year. It's only been offline when I've powered it off myself.

Mine hard locks regularly requiring a power cycle. It is even worse with more recent kernels.
