Looks really interesting! So many variations so fast!
You can kind of guess. OpenVPN is single threaded, so one core; clock speed will govern. Wireguard is multithreaded. The SFT is dual core 1g, the Plus is quad core .7g and A7, and the axt1800 is quad core 1.6g and A53.
So for OpenVPN, it may be Plus, then Opal, then the AXT. For wireguard, it might be Opal, then Plus then Axt. But the AXT looks to be a beast.
