Verdict

Which should you buy?

Winner overall

The GeForce RTX 4090 wins overall for raw performance and larger memory capacity, but the GeForce RTX 5080 offers a more efficient architecture and newer features.

Best value

For budget-conscious buyers, the GeForce RTX 5080 is the smarter pick with lower power draw and newer memory technology at a likely lower price.

When the other wins

If you need the largest possible video memory for heavy 4K texture work or AI model training, the older GeForce RTX 4090 is the right choice despite its higher power use.
