If the RTX 4090 and RX 7900 XT and XTX have the same amount of GDDR6, why does the 4090 outperform the 7900?

Question

I’ve been looking at upgrading my PC in a few months, not to anything this powerful (but a man can dream) and in looking at GPU comparisons I see that the 4090 tends to be streets ahead of the RX 7900’s in terms of performance. Why is that if they have the same amount of memory?

That’s like wondering why one car with an I4 engine with two turbos isn’t faster than a W16 with a single supercharger. I hope that explains everything you need to know.
