"... yet since it is made using one of Intel's 14 nm nodes, it is natural that the said IP consumes more silicon area. To that end, it is not surprising that the new CPU is substantially bigger than its predecessor despite the fact that it has fewer cores."

Rocket Lake's predecessor, Comet Lake, used Skylake cores. The difference in size vs Comet Lake, which was also 14nm, is due to the substantial changes in the microarchitecture in the backported Sunny Cove cores which were responsible for Ice Lake's 18% IPC increase in IPC vs its Skylake based predecessor: cache sizes, register files, etc.

There is a table in this article which compares the two, in the context of Cascade Lake vs Ice Lake Server.
