I recall when AMD EYPC was first released on AWS EC, it was not using SMT: one vCPU was one full physical core.
Is this still the case for new AMD instances?

Each Hyper-Thread for a system will appear to the kernel as a logical CPU core. There may be multiple cores per physical socket, as demonstrated by the lscpu utility:
# lscpu | grep -e Socket -e Core -e Thread
Thread(s) per core: 2
Core(s) per socket: 6
Socket(s): 2
