Yes! You can double the amount of silicon, OR you can increase the power by a factor of four. Both of which will increase multithreaded performance by about a factor of 2. The Intel Golden Cove core is designed to clock very high, but in doing so can consume a lot of power. AMD does not have this capability in their current designs. This is one reason Intel won the NVIDIA design:

Huang says the primary reason for switching CPU brands was the exceptional single-threaded performance Sapphire Rapids offers over the competition.
Many of the reviews that people reference to show very high alder lake power consumption also show the 24 thread alder lake outperforms the 32 thread Ryzen. Intel is using less silicon at higher power levels to compete.

An interesting data point is in the Intel Alder lake core I3 reviews. You will find with 4 big intel cores on Intel 7, versus 4 big AMD cores on TSMC 7 the Intel design has higher performance AND lower power than AMD.

Given the Linpak compute node on Frontier is TSMC N6, while for Aurora it is TSMC N5 we should expect better perf/watt on Aurora.
