Power consumption and compliance with standards
There aren’t really any big secrets when it comes to power consumption, because what NVIDIA specifies as TGP is also largely adhered to. But this is not the whole truth, because the power consumption is very resolution-dependent. However, if you add up the power consumption in Ultra-HD, which I measured in all games over the entire runtime, then everything is back to the feared 280 to almost 300 watts for the TGP, first the respective average over all resolutions, games and graphics cards:
With about 13 to 14 watts in idle, it’s still in the usable range, even though it’s relatively high, because it’s been lower before. The partial load ranges are also implemented relatively economically. However, the card then reaches around 298 watts under real full load and full warming, which is 8 watts more than predicted and stated in the specs. The following table now shows the maximum values of the respective load scenarios and the averaged gaming load. The Gaming UHD value is the highest value averaged over the entire benchmark in a game:
The fact is that nearly 300 watts for a card that is barely 8% faster than a GeForce RTX 3070 FE at 220 watts is a bitter disappointment. That’s not contemporary, nor is it really competitive. However, it will probably scare off the miners more than the gamers.
Which brings us to the specifications, because in the end it is clearly regulated by firmware what is possible as well as maximum and minimum. A maximum of 320 watts is allowed for the VU, which can also be accessed with the appropriate software, but is also completely pointless.
The slightly more detailed curve for Gaming and Torture looks like this, with the long 20 ms intervals still very granular. But I’ll get to the very short spikes in the very next chapter..
