Sapphire Radeon RX 7900 GRE Performance, Power Analysis & Noise Output

Clock Speeds

The charts below show the average GPU clock speeds in various usage scenarios.

Overclocking

Overclocking is easy with this card since the AMD drivers don’t give you much headroom anyway. Most likely AMD did that on purpose, not to have the GRE reach close enough to the RX 7900 XT performance through overclocking. I dialed the maximum allowed GPU, RAM, and power limit values. I run the 3DMark Speed Way benchmark to determine the overclock gains.

GPU & RAM Clocks

Operating Temperatures

Power Consumption

The power consumption is notably higher.

Overclock Gain

For a 6% performance increase, you need 44.5W. You could possibly lower this amount by dialing down the GPU core voltage. Personally, I don’t believe it is worth the trouble to push this card, or any card, to its limits. Just buy a stronger one.
