Seriously, I'd expect anyone on this site to be able read the graph.Seriously guys, please learn to read a graph properly.
As said before, generally X-axis is the control parameter (the source, input) and Y-axis is the response parameter (the result, output). Changing parameter in X results in a change in Y parameter.
In this case the graph depicts COOLER PERFORMANCE at dissipasing 220 Watt of heat. Here the performance of a cooler is characterized by how cool the temperature and how quiet the cooling system is.
For a given cooler design (there's two in the graph, 1080 cooler and 1080 Ti cooler) and constant heat load, the resultant junction temperature (Y-axis) is correlated to the noise generated by the cooling system (here it is assumed that noise is correlated to fan speed).
- By varying the noise (fan speed) the resultant temperature will vary too.
- Take sample at low noise (low fan speed) : with 32.5 dB noise, 1080 cooler results in ~95C, 1080 Ti cooler results in 88C.
- Take sample at high noise (high fan speed) : with 35.5 dB noise, 1080 cooler results in ~87C, 1080 Ti cooler results in 82C.
- Notice that as fan speed goes up (noise increaased) the temperature lowers, intuitive isn't it?
- Notice at the same noise level, 1080 Ti cooler results in lower temperature than 1080 cooler, this is the point that the graph is trying to get across.
I sometimes wonder if this kind of error is the cause of some baffling decision from governments and companies.
How about adding something like *at constant GPU load. If Nividia were really smart they would've simply put the noise delta on the X axis otherwise this is what people can interpret & they're not wrong either ~
