A RTX 5090 575W TDP using TSMC 2N = .. TDP

[5090 using TSMC 2N]

Hey NVIDIA, RTX 5090's 575W TDP is really nasty. How expensive would it be to port 5090's 512-bit chip from TSMC 4N to 2N node? 2 node jumps, and an power efficiency improvement by 30% after each full node jump, means the 575W TDP would become: 575W / 1.3 (TSMC 3N) / 1.3 (TSMC 2N) = 575W/1.3^2 = 340W TDP.

Also, while you are at it, offer a 48 GB VRAM version (using 3 GB per chip chips, instead of the current 2 GB ones).
(RTX 5090 desktop: 512-bit/32-bit per GDDR7 chip = 16 GDDR7 chips, 2 GB each = 32 GB VRAM. Using 3 GB per chip = 48 GB VRAM. The 5090 Laptop, which is a 256-bit 5080 desktop (16 GB VRAM) in disguise) is already using 3 GB per chip chips)
