Native frames are the starting point
At 4K Ultra, the cited 16-game geometric means are 84.4 FPS for the 4090 and 70.1 FPS for the 5080. Use the interactive comparison to change resolution and inspect 1% lows.

What reviewers found
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.

Bars start at zero. Percentage differences use the displayed baseline; they are not a combined rating. A geometric mean summarizes a suite, not the frame rate of every game. 1% lows describe the slowest portion of frames and help expose uneven delivery. Missing products are never assigned zero.

Tom’s HardwareThe 4090 provides 24GB versus 16GB on the 5080. Capacity is not a speed benchmark: check the memory footprint of your model, context length, application and precision.
TechSpotIn the separate 19-game power suite, the 5080 draws 297W and the 4090 401W. Include case clearance, the power supply, cooling and warranty when evaluating a listing.
Tom’s HardwareKitGuru found the 5080 roughly 15% behind the 4090 in rasterization and 19% behind with ray tracing in its launch review. The smaller card improved efficiency, but the result reinforces the case for keeping a 4090. These percentages belong to KitGuru’s suite; they are not averaged with the charts above.

The 5080 improves on the 4080 Super by 4% at 1440p and 11% at 4K in this suite. The compact cooler fares well, but those modest gains weaken the upgrade case. This is the video version of the TechSpot review already included in our sources.

KitGuru’s launch tests found a small gain over the 4080 Super, improved efficiency, and performance below the 4090. It liked the compact cooler but did not see Multi Frame Generation as sufficient reason to upgrade on its own.
