Arc B580 Low power usage Monster hunter Wilds

[Puffalo]

I think that Monster hunter wilds is not utilizing the full power of the ARC B580
I also think that other games are not using the full power of this card either but it is subjective.

i9-9900KF
B580
DDR4-3200
Pci-e 3.0

Before i Upgraded to the B580 i was using a GTX980TI, That card had a TDP of 250 watts and during normal gameplay when it was at max usage it would hover between 240-255 watts in any game EXCEPT MONSTER HUNTER WILDS.


In monster hunter wilds the GTX980TI only ever used up to 155W out of its total 250W TDP.
Other cards from Nvidia did not have this issue, in fact that card was equal to the GTX 1660 which was listed as the minimum specs for that game, yet the benchmark only went up to 30fps at the lowest settings, which is less then what the 1660 got by a huge margin.

Why am i bringing this up?

The Arc B580 Seems to be using between 80-105 watts of power during this benchmark, even when overclocked the card would only use 110 watts of power.
With the superposition benchmark at stock clock speeds the power usage is 140-148w

When overclocking, the superposition benchmark would use 168-174w 
The B580 has much more headroom it seems but is not making use of the total power that it is capable of.

I will attach a picture of the monster hunter wilds benchmark along with a screenshot of the superposition benchmark with an overlay that shows the "reported" power at stock speeds.

I think this is something the team should look into if they are not already.
For reference monster hunter world uses around 125w at stock clock speeds.

Monster hunter games downloaded from steam.
Benchmark downloaded from the benchmark website.

*I added some benchmark power usage screenshots as examples of normal power usage vs low power usage*

I know that not all applications use the same amount of power to render scenes, but this card is only using 70% of its total capacity to render Monster Hunter wilds and 89% on Monster Hunter world for comparison.

Hello Puffalo,

Thank you for sharing the information. You might want to consider upgrading your CPU to meet the minimum requirements and help reduce bottlenecks. I will investigate this issue further and will get back to you once I have more information.

I will upgrade my system when my budget allows for it. But i do appreciate the advice.

Hello Puffalo,

To enhance game performance, optimizations will be implemented as the drivers evolve. Additionally, consider upgrading your processor to meet the minimum requirements to prevent performance bottlenecks. For future system upgrades, you may want to reach out to an Intel Authorized Distributor.

I have not heard any updates on this issue recently.
The B580 still has low power consumption issues across a very wide variety of games.

For example, if i lower the resolution in a game, instead of giving me more framerates, it lowers the amount of power usage from the graphics card. (ok sure it gives SLIGHT improvements, but the power usage decreasing offsets the potential improvement)

For another example. i have BOTH an RTX 4060 and B580

The RTX 4060 has a TDP of 115w and CONSISTENTLY reaches the power usage in EVERY game. (+-5w)
The B580 CONSISTENTLY runs around 140w of total utilization when its TDP is 190w

One thing to note, I keep getting a "Thermal Throttle" notification while using HWinfo, But the GPU temperature never exceeds 70C
Also, PL 2? What is that and why is that also an issue. 
I would love to hear a response from the team

The longer i run *ANY* game the more the PL2 throttle reason percentage goes up.
That percentage is an average apparently.


In order to get Furmark 2 to use the same amount of power as it does in Monster hunter wilds, i need to lower the power limit to 68%
my framerate drops from 98 to 77
wattage drops from 145w to 95w (Monster hunter wilds runs between 85-100w)

Under "Cpu" the top number is total core usage, the Bottom number is MAX SINGLE CORE usage (highest % on any core), and i have never seen it reach above 88% in monster hunter wilds. I promise it is not that.

I have seen my other computer with a weaker cpu, paired with a RTX 4060 hit higher framerates (up to 70fps) at the same settings.
i barely see 60fps. mostly around 35-50fps with the recent update. (mostly lower 40s)

[Puffalo]

Changing power limits from 68% to 100% results in a net 0 fps gain.
Going as low as 65% does not change power or framerate
going to 64% finally lowers framerate by 2fps and power consumption by 3 watts.

Try downloading HWinfo, and look at the TBP Total board power and see what it reads.  Looks like your numbers are only the TGP total gpu power which are misleading.

[Puffalo]

Furmark 2. 
Look at TGP and TBP

 Over here are MAX values. 

After playing Monster hunter Wilds for 10 minutes.

I included a HW info log, Though I'm not sure how useful that would be.
Missing 50w of power, its worse then i thought.
When running around in game my (TGP) hovers between 85-100w, rarely 105w.
Guess the title screen draws the most power here.

PCIE 3 

Just asking, but does that even have resizable bar ?   

And have you enabled it ?

[Puffalo]

Yes, Pci-e 3.0
Yes i have RE-BAR enabled

Its saying something that im using unsupported hardware and i still have the same performance as people that are actually using proper components (in the tests i have done).

Most of the screenshots are from youtube and have the system specs included in the screenshots.
The issues are not my PC specific.

[SJN]

Hmmm...maybe your cpu is just not up to the job.

Just trying to compare........say the AMD 5600X.  All the b580 revierws say this CPU is not enough for the B580.

And when you compare the 5600x to the 9900KF, then it seems that they are about equal ?

[Puffalo]

My i9-9900KF is slightly better than the i7-10700, plus i have a slight overclock. so far with this setup my GPU has always stayed at 100% utilization, meaning my cpu has some headroom.

Monster hunter wilds uses all the cores pretty evenly so its doing pretty well
I mean i played oblivion the other day at over 400fps, pretty sure i was cpu bound there lol
