Noise Comparison Videos: 500 FPS
Coil Squealing at 500 FPS
We commonly get complaints from readers about coil whine from graphics cards in older games or game menus, where very high frame rates are common. We're not strangers to this phenomenon, so we tested each graphics card at 500 FPS using an Unigine Sanctuary loop.
Every single card, including EVGA's GeForce GTX 690, demonstrates at least some squealing at these frame rates. It's barely noticeable from the dual-GK104 board, and the HIS 7970 X2 isn't too disturbing. But again, PowerColor's Devil13 HD7990 is barely tolerable.
