Ampere clock speeds.

[Tired9]

So I have been in the process of undoing my maximum OC on my GPU to allow my system to run a lot quieter but also run with less juice used.

I used Horizon Zero Dawn to test power consumption and noise whilst adjusting clocks / voltage / power limit and fan control.

From 2055mhz down to 1850mhz, I only lost about 5 FPS..., with these settings below.
The clock speeds range between 1850-2010mhz dependant on the game and power load.

So if it is only 5 FPS, why are they trying to clock these cards so high from factory?

Also I would like to note.. capping my FPS to the lowest number hit, so for example, Metro Exodus Enhanced with RT on and PhysX will average somewhere around 89 FPS with lows in the 70's, So I capped it to 70 FPS for a solid experience..

109 watts used and the GPU sat at like 1290mhz max, 47c top temperature.

I know it is a very different generation but like 700mhz base clock vs 850mhz on the GTX 480 would net an average boost of around 11 FPS.

yeah no idea, i dropped my core voltage down to 875mV and get around 1860 stable for 30% less power usage and a very small fps dip

You should test your undervolt with Cyberpunk 2077 or Dying Light 2 to see if stable. The RT and DLSS use in these two titles gives the GPU a decent workout. 875mV at ~1905MHz appears popular.

I think a large part comes from the Boost tech with these cards. The cards clock up and down aggressively when there is power and thermal headroom. On thermal side the coolers are pretty good so headroom there. On the power / voltage side, they pump more voltage in then needed to account for duff chips. So usually power / voltage laying around which for most cards means they will boost in clock speed, while for the absolute worst samples ensure they still work perfectly fine. Can leave it to more advanced users, such as those on here who bother with voltage / power tweaks to gain the benefits of running more efficient, while also having a card that just works for other users.

Also going to depend on resolution and games. Personally I like to undervolt (compared to stock) and overclock, best of both words

I remember when they announced Ampere, the TDP's gave me the impression that Nvidia was "turning it up to 11".

I thought (and still think) it's because AMD was finally going to be competitive from a raw horsepower perspective and Nvidia needs to win, even if only by single digit percentages.
