RTX 5090 laptop GPU shows no real-world performance gains over the RTX 4090

Facepalm: If you're planning to buy a new gaming laptop powered by the RTX 5090 mobile, you might want to hold onto your wallet a little longer. A noted hardware reviewer who tested the new GPU claims that it doesn't offer much of a performance boost over its predecessor in dozens of popular games. According to early comparison tests carried out by Australian tech reviewer and YouTuber Jarrod Farncomb, the RTX 5090 mobile offers only a minor performance uplift over the RTX 4090 in most games. On average, an RTX 5090-equipped laptop managed around 66 frames per second at 4K across 25 popular titles, while an RTX 4090 laptop with an older CPU and slower DDR5 RAM achieved 65 fps. Things got worse at 1080p, where the RTX 4090 laptop managed to outperform the newer device, hitting 133 fps compared to the 132 fps clocked by the RTX 5090. At 1440p, the two laptops managed 106 and 107 fps, respectively. The difference in each case is negligible, but the tests suggest that the new GPU doesn't ... Read full article.
