Oh, I see, your qdot allegiance is changing, huh. (Awesome job on this, other qdot. :) )
Someone tried PCIe on the Raspberry Pi 4 already. Yes, the wiring job is horrible, and yes, of course it works, as I've said many times. Go hack on PCIe already, it's easier than you think. Now someone needs to stick a Radeon RX Vega on there, for kicks. http://mloduchowski.com/en/blog/raspberry-pi-4-b-pci-express/ …

I was just looking at this in a bramblebox for a plex server

Thats super interesting. Also agree on the SI part. PCIe is only 100MHz which is reasonably resilient. IMO DDR is far more difficult than something like PCIe but even DDR3 is within the reach of hobbyists.

PCIe is not 100MHz, lol. The refclk is 100MHz, but PCIe 1.0 pushes 2.5 Gbaud over each lane (1.25 GHz bandwidth) and it goes up from there. But the PCIe PHY is amazing and can deal with a surprising amout of bullshit.

Author, reporting in :) That didn't take long to be noticed.

Appreciate the sharing of these knowledges esp to someone like myself who nv went to sch for electronics. Now anyone has no excuse not learn

proper SATA would be nice, though there is also bananapi

is it known how much address space there is for PCIe in that broadcom chip? GPUs normally need a lot

Next up, Pi + NVIDIA GPU for Tensorflow; drivers from jetson might work out of the box?
