There’s a benchmark done with the EdgeRouter that shows that Wireguard’s throughput exceeds that of hardware accelerated AES + IPSec:

Of course, benchmarks from random strangers are not gospel, and the results aren’t particularly damning. But even then, you’re assuming that you have the luxury of running on a chip that comes with a hardware crypto engine. Good luck trying to get AES encryption/decryption speeds at anywhere near line rate with a Raspberry Pi or a run-of-the-mill router.
