Speed and memory
In our performance index the GeForce RTX 3080 Ti Laptop scores 40 and the GeForce RTX 5060 scores 36, which makes the GeForce RTX 3080 Ti Laptop about 11% faster. That is a small gap, below what most people notice without a frame counter.
The GeForce RTX 3080 Ti Laptop has 16 GB of video memory and the GeForce RTX 5060 has 8 GB. That difference matters at 1440p and in new games at High textures, and it can outweigh a small speed advantage as the card ages.
In our estimates for popular games at 1080p on High, the biggest gap is in Cyberpunk 2077 (103 against 93 fps), and the smallest is in Red Dead Redemption 2 (133 against 121 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.
