Wait, if you can, for next year' Refresh, which will use 3 GB per GDDR7 chip, instead of the current 2 GB (8 GB VRAM will then become 12 GB VRAM). The 5090 Laptop with its 24 GB VRAM is only a 5080 GPU chip (=256-bit) in disguise, otherwise it would only have 16 GB VRAM: See en.wikipedia.org/wiki/GeForce_RTX_50_series#Mobile, the same GB203 chip is being used for 16 GB and 24 GB configs: 256-bit / 32-bit per chip = 8 GDDR7 chips, once with 2 GB per chip (=16 GB VRAM) and once with 3 GB per chip (=24 GB VRAM). This is common knowledge.
