Power Consumption
The Radeon Pro W5500 is meant to be a low power option, so we wanted to test this. We set the VRMark Cyan Room test running as a loop, then measured total system power consumption. We also tested the system at idle, with nothing running.
When idle, the Armari workstation is quite frugal, drawing just 51.2 Watts. However, as the TDP suggests, the NVIDIA Quadro P2200 is the least power-hungry card here, drawing 182.2 Watts compared to the W5500's 252.3 Watts. The W5500 is doing 64 per cent more work but consuming 54 per cent more power, so it is a little more efficient with this task.
Temperature
We also checked the temperature of each card before we began the VRMark loops, and then during once it had settled to a constant value.
Not surprisingly, the lower-power NVIDIA Quadro P2200 is also the coolest running of the three cards, when under load and when idle. The W5500 runs the hottest, although 84C is nothing to worry about. The W5700 has much more substantial dual-width cooling, so can cope with its extra power well.
