Xbox Series S vs Steam Deck die size (alien.top)

The OG Steam Deck (7nm, comparable to the Series S) has a die size of ~162mm2. In there, it packs an 4 core, 8 threads CPU and a 8 CU GPU.

On the other hand, the Xbox Series S packs an 8 core 16 threads CPU with 20CU GPU of the same architecture in ~197mm2 die.

This is a technical question, how come the Series S packs much more in just 25% more size? I'm not saying the Steam Deck should be as powerful as a Series S (that'd never happen, the power constraints would not make it possible), but I wonder if the CPU in the Series S is cut-back or if there's anything in the Steam Deck's SoC that could have been removed to get a lower cost.

Well for starters the memory controllers are smaller on the series s.

Its also 8 cores vs 4 cores.

The Series S also packs 24 CU. With 20 enabled for gaming. The steam deck has 8 CU

For reference the series x has 52 out of 56 enabled. the Ps5 has 36 out of 40 enabled.
