Oh, I see...ignore that completely..."CPU whine" was an issue with certain Macbooks a few years ago.modecai wrote:I just can't find a good description of what the cpu whine is... Or what quiet mbp is supposed to do. I'll do some more googling.
They created an audible noise, the root cause was down to power saving in the C2D processors.
QuietMBP resolves this defect by making your processor work even when it is idle - stopping the power saving modes.
However, we are using QuietMBP for a different reason.
In Windows you can stop power saving by setting your power profile to "High Performance"...you can't do this in OSX and it can cause higher CPU usage due to the CPU being in a lower power state.
QuietMBP gives me better CPU usage whilst using Ableton because it doesn't ramp down during the idle gaps (the CPU ramps down even under load, the idle "windows" are milliseconds long).
Hope this makes sense.
