I meant horizontal spacing between USB-2 and USB-3 ports.
Wide dongles cannot fit side by side if spacing is like that of Pi Model 4.
I think the horizontal spacing between the USB connectors is also the same between the RPi 4 and RPi 5 (the PC board size is the same).

Itâs unchanged, theyâre next to each other.

Even with an airspy a pi 4 is only running at about 50% capacity without overclocking. The pi 5 is apparently quite a lot more efficient for the same workload, so it should use a bit less power if itâs not doing anything extra. Probably not enough to warrant the purchase price if thatâs the only reason for upgrading.
Itâs actually worse than a pi 4, which has a 1.2A limit shared between the 4 ports. Apparently you can manually override that limit to get the higher 1.6A limit even when using a 3A PSU, but if the system load is also high that might be a bit much. The 5A is probably a sensible choice if intending to run multiple dongles or other peripherals.

Iâve not looked yet but are there PoE injectors that can supply the extra required current?
Yes there are.
This one is 30W

There is a good in depth (UK) review of the Pi5 covering most aspects such as power consumption, fan noise, speeds and comparisons with a Pi4.
