AMD Radeon RX 7800 XT & RX 7700 XT Performance, Power Analysis & Noise Output

Equipment Used

I use a Class 1 Bruel & Kjaer 2270 G4 sound analyzer equipped with a Type 4955a microphone with a dBA-weighted dynamic range of below 6 dBA and up to 110 dBA. All tests are conducted inside a hemi-anechoic chamber with close to 6 dBA noise floor and at 25–28 °C ambient. The test subject is placed a meter from the sound analyzer.

Frequency Plots – RX 7800 XT

Tomb_raider_game_QHD

Noise in the 400Hz – 2KHz region increases during the benchmark’s duration. In the game’s menu, the 400Hz frequency is the dominant.

Frequency Plots – RX 7700 XT

Tomb_Raider_Menu_2.5KHz

Gaming_Tomb_Raider_QHD_freq_plot

Again, 400Hz is the dominant frequency, with 2500Hz following. During the game benchmark, the RX 7700 XT is less noisy than the RX 7800 XT by a significant difference.

Signal Recordings – RX 7800 XT / RX 7700 XT

I have recorded the noise of the graphics cards while running the Shadow of the Tomb Raider benchmark at QHD, but please keep in mind that I’ve enabled Automatic Gain Control (AGC) to do so to make it easier for you to reproduce them. The provided recordings are only offered for aural identification purposes.
