PNY NVIDIA RTX A4500 Professional Graphics Card Review

Power Consumption

Of course, these days focus has also shifted towards performance per watt, as the price of electricity has shot through the roof with no sign of dropping anytime soon. For this test, we fired up the Blender Gooseberry benchmark again, but this time using GPU acceleration, which hammers the device during a multi-frame animation render. We compared power when idle with the power consumed when GPU rendering.

The A4500 is quite frugal when idle, with the board consuming just 13.7W. At full pelt, it hits its TDP ceiling on the nose, consuming 202.2W. Considering the amount of GPU compute power it is delivering here, that's not a bad result. When we ran this test with the A4000, it also hit its TDP closely, drawing 139.3W.

Temperature

We also checked the temperature of the A4500 before we began the Blender Render, and then once it had settled to a constant value. We performed this test with the A4000 as well, for comparison. Note that it was a particularly cold day when we were testing and we weren't heating the test room above 20C due to the energy crisis.

Despite the extra GPU power of the A4500, it actually runs cooler than the A4000, sitting at just 26.7C, where the A4000 sits at 33.1C. It was the same story at full pelt, with the A4500 hitting just 73.7C and the A4000 85.6C. This is very likely to be because the A4500's dual-width format enables a meatier cooling system, which is clearly very effective at doing its job. For a card with so much GPU compute potential, this is extremely reassuring.
