Total System Power Consumption
We're back to positive news when it comes to power consumption. Whilst you can't expect a processor with 32 cores to be miserly, we were pleasantly surprised with the 2990WX in this area. To test the relative system power consumption of the workstations, we plugged each one into a mains power meter, which records various details of electrical behaviour.
In particular, we wanted to see approximately where the system settled when idle, and then when running the CPU at 100 per cent load. We ran the Blender Gooseberry Production Benchmark again and used our mains power meter to give us a maximum power consumption reading.
The PC Specialist Nucleus does very well in this test. Of the four systems compared, it draws the least power when at full pelt. Relatively speaking, you are getting a decent amount of processing performance per Watt, better than the 16-core Ryzen Threadripper 1950X.
But although the 18-core Intel Core i9-7980XE is drawing a little more power, it's also doing a bit more work in the same time, and the Armari Magnetar S32T-RD1000G2 renders a lot quicker, so its 18 per cent greater power draw is offset by the 89 per cent more work done for those Watts.
