Gpu not reaching full power

[DESTROYER 123503]

So i have a sapphire rx 590 nitro plus gpu and it has dual bios normal mode and performance mode. This gpu has a max tdp of 225w but it never reaches 225w even if i put the gpu in performance mode and it says max tdp 175w in both modes. Is this normal?

I would suggest to benchmark performance, rather than looking at a guestimate of TDP.

I'm sorry but.......

is this literally the only issue? that gpu-z somehow calculates the wattage incorrectly , did you actually benchmark the card or test the card at all?

or are you only staring at a gpu-z figure that is calculated without any form of hardware that can actually read the wattage of the card...

While benchmarking the gpu at max tdp is 185w

It does not go higher than 185w

no..... cpu-z isn't displaying a number higher than 185......

you however , have no idea what wattage the card is at becuase you haven't actually read the wattage and are instead just looking at a guesstimated number on a freebee gpu app.

have you benchmarked the card , or are you just going to stare at this number.

i am using msi afterburner to check my gpu tdp

[Eigenvektor]

Thermal Design Power (TDP) := How much heat should the cooler be able to dissipate in order to keep the silicon's temperature at acceptable levels.

 

In other words, TDP is not a measure of performance and does not reflect actual power draw or heat output

 

By "look at benchmarks" I mean: how much FPS do you get. That is important. Forget/Ignore TDP.

Yes i did benchmarked the card and used msi afterburner to moniter mu gpu power and doesnt go higher than 185w.

Does tdp matter when ocing a card?

The tdp can display as 1w for all i care (you should too)....... how does the card actually perform? stop looking at the tdp and look at the actual benchmark results

[DESTROYER 123503]

90 to 110 fps on ultra on most games. Ac orgins 60fps on ultra

I dont really know about this kind of stuff so thats why im asking if this is normal.

tbh tdp you dont need to think about for permanence if your not overclocking

Yes, it is normal. The app doesn't measure actual TDP, it estimates it. If you want to know actual power draw and heat output you'd have to measure it using hardware sensors.

 

TDP is a measure the chip manufacturer uses to give card manufacturers a value to work with. How much heat do we expect the chip to generate under max load (thermal design power). This allows card manufacturers to design their cooler to be powerful enough. It doesn't say anything about the card's performance.

 

As @emosun said, so long as your FPS in benchmarks and games are as expected, everything is fine. You'd have to compare your OC results to other cards with the same overclock to see if you're doing better or worse.

that right there along with the temp is really all you should care about. so long as that falls in line with 90% of other peoples results then the card is performing normally.

I think the only time you care is if you unlock voltages and disable safeties (e.g. when going for extreme overclocks on LN2) and you want to keep your card alive. In that case you'd use actual hardware sensors to measure power draw and heat output in real time, rather than using an app's best guess.

I am planning to overclock. I increased the pl to 50 and the core voltage and it tops out to 185

How can i use hardware sensors as i am new to this kind of stuff

Take a look at the yellow devices on the table.

This is what I mean by hardware sensors. Stuff you can attach to your GPU to measure it's temps etc. And seriously, I wouldn't bother with this type of stuff unless you're planning on overclocking with LN2. Just overclock manually and look at frames per second in games. If the values match other peoples results with a comparable overclock = nothing to worry about.

yes that is what i meant
