While the minimums is impressive (and makes me shake my head at AMD still doing so little to tweak things as its making them look worse for no reason), The rest isn't too crazy (although I might be not understanding the overall perf/W improvement that's bringing, plus I don't know what settings they were using so they might be at higher voltages than others were getting or might be getting better than others too), although its still nice and is exactly what people have been seeing from AMD GPUs. I wonder if the APUs are similarly affected (well the big console ones seem to be, hence Microsoft putting effort towards that with their "Hovis Method"), and I think it'd be extra beneficial there (but I also guess the CPU guys do a better job of managing voltage, plus I believe they run at lower clocks as well that are probably more in the efficient range of these GPUs).
The article was updated to show why temps were higher while undervolting. Turns out the fan speeds are tied to power draw. So when you drop the power usage by 20-40 watts, the fan also slows. With the card in this config, its power usage matches that of the 2080.
How much watts do the fans use? And I assume you can do fan profiles like you can on other cards?
Just curious. Anyone ever tried undervolting + chill? Can that even work?
It should work, but I personally don't ever use Chill as it causes stuttering/hitching too much when playing as it tries to aggressively change power states, and so doesn't end up being worth it. It'd benefit people that spend a lot of time Alt+Tab out of games where the game is minimized or not the focus though, so it'd drop FPS for games that don't have a setting for that (Diablo 3 does, and I'd guess other Blizzard games have that as an option).
That's weird. Undervolting lowered temps on mine using the standard fan configuration. By a lot.
Not yet, but that does sound like an interesting experiment.
Yeah I'm not sure why temps wouldn't be lower, and wouldn't the standard fan profile be fairly aggressive so you'd think it'd be more aggressive as its expecting to deal with higher temps from the higher stock voltage and TBP, but perhaps there's some weird issue. Does H test on open bench or something where its causing a delay in the fan response to temps, or that might be causing some sensors to report cooler than stock (like around VRMs or something) and so its not kicking the fans up like it does for stock.
