The two dips in our chart correspond to breaks between loops in our Metro benchmark sequence. FurMark Average power through 15 minutes of FurMark rises slightly versus what we saw under Metro. Richard Devine Richard Devine is an Editor at Windows Central. Powenetics, In Depth For a closer look at our U. There's not a huge amount between them, and both should be capable of decent frame rates and 1440p gaming. Power over the auxiliary connectors is kept to a minimum.
We still have a lot of work to do with these cards. If we were to guess, though, it looks like the fan responds quickly to a rapid increase in temperature, up to its maximum rotational speed. The result is a much more straightforward comparison. . A former Project Manager and long-term tech addict, he joined Mobile Nations in 2011 and has been found on Android Central and iMore as well as Windows Central. As the change in temperature slows, the fan slows to allow higher thermal readings and better acoustics. July 7 is 7nm day for the red team! Mainly, it consistently dialed fan speeds back under even normal gaming workloads, causing temperatures to increase.
Custom software logs the readings, allowing us to dial in a sampling rate, pull that data into Excel, and very accurately chart everything from average power across a benchmark run to instantaneous spikes. Both Navi-based Radeons, then, demonstrate similar behavior under extreme workloads like FurMark. FurMark Power consumption jumps a bit under FurMark. Early reviews suggest that it's a pretty close run thing. A peak measurement of almost 264W is a one-time event caused by a spike to 11.
Otherwise, power consumption over time is relatively steady. A single 243W peak is nothing to worry about. Not all is perfect in Navi-land, though. Both 5700s use less power than their predecessors. Notice that every power consumption spike is preceded by a dip, but not every dip is compensated for with a spike.
Peak power consumption, however, only gets up to about 202W. This theory falls apart somewhat when we see the same behavior under FurMark, where clock rates clearly suffer as the fan does something similar. Cumulatively, we end up with an overall line chart that appears more dramatic. They generate appreciably less noise. . .
