Sapphire RX 7600 Pulse Review

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 Cyberpunk 2077 for 30 minutes for 30 minutes.

Speaking of noise, we can clearly see the Pulse is quieter than the reference design, by 3dBA according to my sound meter. In my testing the Pulse saw the two fans run at just 21%, or 1270rpm, resulting in whisper-quiet acoustics. Unlike the reference card too, I didn't notice any coil whine from the Pulse, so that's a definite plus – although it can vary from card to card.
