We've experienced something similar: for compute-heavy rendering tasks, AWS just wasn't good enough. EC2 machines with the same spec perform much worse than Hetzner machines

Yeah, even when you move to "EC2 Dedicated Instances" you end up sharing the hardware with other instances, unless you go for "EC2 Dedicated Hosts", and even then the performance seems worse than other providers.
Not sure how they managed to do so for even the dedicated stuff, would require some dedicated effort.
