Nvidia RTX 5080 Review: Efficiency Gains, Performance Letdown

We take our noise measurements with the sound meter positioned 1 foot from the graphics card. I measured the noise floor to be 32 dBA, thus anything above this level can be attributed to the graphics cards. The power supply is passive for the entire power output range we tested all graphics cards in, while all CPU and system fans were disabled. A reading under load comes from running A Plague Tale: Requiem for 30 minutes.

Noise levels are slightly improved over the 5090 FE, too. My 5090 ran the fans at 46%/1585rpm, whereas the 5080 is slightly more relaxed at a 42%/1475rpm speed, reducing noise by 2dBa. I'm also happy to report I didn't notice any coil whine on the 5080.
