You were thinking about the PCIe connection? I hadn't noticed that.

But, the 7c80 / 7c81 use an SPI connection to the Pi.

Compute module + interface + 6i25 + 7i76 = £47 +  £33  + $228 = €280
Pi4 + 7c80 = £54 + $249 = €260 (and a much more compact installation)

Of course the really neat solution would be a 7c80 with a compute
module slot and USB / HDMI breakout.
