Verdict
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.
NVIDIA TITAN V
5.5 / 10 Expert Rating
A fascinating slice of GPU history for FP64/Volta-specific compute, but a poor general-purpose buy today given the lack of RT cores and its niche VRAM capacity.
