The RTX 5090 only has 32gb of VRAM. So the tradeoff is NVIDIA is for blazing speed in a tiny memory pool, but Apple Silicon has a larger memory pool at moderate speed.

Or, there's the DGX Spark, which effectively neutralizes both of these trade-offs, and is the same price as the RTX 5090.
For reference, DGX Spark is at 273 GB/s
It's not 5090 performance though.
Nothing stops you from plugging in a 5090. Nvidia ships ARM64 GPU drivers.
