Most crypto beyond the initial key exchange is symmetric (AES, ChaCha) and those are still resistant to quantum attacks (well beyond the brute force search speed ups). Post-quantum key exchange is fast enough that it doesn't need dedicated units, unless you're in some super constrained environments. But in that case you'll run into other issues too.
