Based on the questions on this list earlier, there= is a folder with device information for each of the devices

For example, the Pi4 and the Lichee Pi (ri= sc-v) hardware layout is here:

The switch has also been upg= raded to a Cisco 3750x, which I think based on the "show interface&quo= t; output has a max queue size of 40 frames.=C2=A0 The test process clears = the counters before each test and gathers the "show interface" ou= tput at the end.

The Lichee Pi 4A doesn't = look good ( https://wiki.sipeed.com/hardware/en/lichee/th152= 0/lp4a.html )

I really wish the flent was working,= so I'll probably see if I can work out the parsing.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 The announcement was end of October, but I thin= k I could pre-order right now if I was feeling an urge. You are right thoug= h, announced !=3D available or delivered.

P.S.: I have a pi400 in use as "desktop" for my oldest kid, this = is close to be actually generally usable, I would guess that changing a pot= ential p500 from the pi400's 4GB to 8 GB together with the other impriv= ements the 5 brings might push it over the threshold into the truly useful = category.

And I understand that there are other capable ARM based SoCs for homerouter= /desktop duty, I just happen ot have a soft spot for the raspberry project = ;)
