NVIDIA GeForce RTX 4090 (Founders Edition)

Cat. no. gpu-rtx-4090

Curator note

The fastest 24 GB card: same VRAM as a used RTX 3090, with much more compute, so prompt processing and image generation are clearly quicker. It costs a lot more than a used 3090 for the same model size, so it earns its place only when speed matters. It draws 450 W through one 16-pin cable that must be fully seated, and at three slots wide a multi-GPU build needs risers or a frame. New Founders Edition stock is scarce, so check the seller before buying.
