Temperatures, Clock Rates, and Infrared Measurements
Although the card’s clock rates on an open test bench look good, they break down once we install XFX's Radeon RX 590 Fatboy 8GB OC+ in a closed case. Our charts make it easy to see the connection between frequency and temperature in a real-world gaming sequence and FurMark.
For the power consumption we measured, XFX’s cooler really does seem to be a limiting factor. Something larger (and quieter) would have certainly helped. To be sure, a constant 1580 MHz is only possible in a really well-ventilated case.
Here’s what our results look like in table form:
|Initial Value||Final Value|
|Open Test Bench|
|GPU Clock Rate||1580 MHz||1580 MHz|
|GPU Clock Rate||1580 MHz||1527 MHz|
|Temperature Inside of Case||25°C||45°C|
The following images include infrared measurements from our gaming and FurMark loops, both on an open test bench and in a closed case. Differences between the two environments are readily apparent, especially since the cooler is operating at its upper limit.
