AMD Gpu Power maximun and Total Board Power

Hello,

I would like to ask what difference there is between Gpu power maximun and Total Board Power.

Moreover watching HWinfo I see it reports Higher value of Gpu power maximung (193W) than TBP (134W, same value reported by Adrenaline for GPU power consumption).

Power Maximum is the instant (short) spike in power while other values reflect the power consumed over a specific averaging period.
 
Hello Martin, thank you for your reply.

Does it mean that the power consumption spikes all the time while gaming?

I play with FPS cap coz of my monitor but the difference is quite big.

Not all time exactly but quite a lot

Here is a 3 hours gameplay session
Limit of the board is 375W
Max value is ~110W over the limit and average value about 80W over the average board power.

Hello Zach, thank you for your reply.

Mine seems to be spiking most of all the time during gameplay session.

I undervolted and lowered the clock to the stock stated on Sapphire, we use the same card.

Now I opened the game and the max valure is constant at around 200 - 220 W meanwhile TBP to 141W.

I will try to undervolt slightly more.

With 2700MHz as top clock I bet you can go down to 1040~1050mV at least

Mine at 2850~2900MHz with demanding games needs 1070mV and less demanding games down to 1050mV.
Of course not all GPUs are exactly the same, even on same model as we both have.

Also dont look power maximum at non gaming apps. If you want to examine exactly what the GPU is doing try this
Get ready to run your game... First reset sensor values by clicking the clock (down on the right) and quickly start the game. Play at least 60min (longer if you use game menus frequently, like map, inventories and such). When finish and close the game, quickly take a screenshot of HWiNFO.
On the left side down corner you can use the arrows to have multiple columns visible like my screenshot.
 
Hello Zach,

Here the Screenshots after 60 minutes of gaming.

I attach also the PSU Power in Graph.

Average Total BoardPower: 163W
Average Power Maximun: 251W

Delta so big, spikes quite a lot.

What game is this?
Looks like its not consistently loading the GPU. Only 58.5% average GPU utilization.
If GPU load has large fluctuations then I think its normal to have bigger spikes.

I usually have 90+% average GPU utilization, so the load is more stable and so the power.

I was playing monster hunter world (I use the texture pack too came by dlc, so it takes around 10gb VRAM), but, as stated earlier, I play with frame limiter because of my monitor is 100hz maximum. Gpu usage is never maxed out.Would be a waste of electricity and more heat otherwise for me.
My only concern are those bigger spikes and delta between tbp and the max power. I was expecting a low electric usage by not pushing higher the GPU too.

You do have low power consumption. Its only 163W by average.
The 251W is the average spike peaks not the avg power of the card.
 
Instant (short) power spikes are normal. They just should not exceed power delivery (PSU) capabilities.
 
Sorry for refloating this, but i'm ditching adrenaline for monitoring and trying to use this with riva tuner.
What's the power metric i should be following here, and which one is the GPU frecuency clock? i can't figure out for the life of me, and ppl around seem to be just as confused, some say shader effective, some say front end clock, and some say shader clock frecuency limit, which doesnt make any sense at all.
