Verdict
NVIDIA Quadro RTX 8000
6 / 10 Expert Rating
Legacy flagship whose sole remaining selling point is VRAM capacity; a used bargain for memory-bound pro work, a poor choice for anything compute-bound.
NVIDIA GeForce RTX 4090 Laptop GPU
8 / 10 Expert Rating
Still a genuinely fast mobile GPU, and a smart buy at a discount now that Blackwell laptops have taken over the flagship spot.
