GeForce RTX 5080

Best forA new high-end build balancing gaming performance and power

The 5080 uses substantially less power than the 4090 in the linked gaming tests, but it also delivers fewer native frames and has 16GB of memory instead of 24GB. Multi Frame Generation can make supported games look smoother; it does not erase that performance gap. The strongest case is a new high-end PC or a move from a much older card.

GeForce RTX 4090

Best forNative 4K performance and workloads needing more than 16GB VRAM

Keep it if you already own one. Its 24GB of memory and stronger native 4K performance make the RTX 5080 a poor upgrade from a 4090. Buying one now is a different decision: a large power draw, bulky coolers and the warranty on a used card all need to justify the asking price.
