RX 9000 series GPU Owners Club

On the previous page, post #1,052, I compared the clock at 4K vs 1080. We saw that 1080 had a gain of 260MHz compared to 4K. I believe that the heavier the workload is, the lower the clock will be. And the lighter the workload is, the higher the clock will be. I suspect the benchmark you are using may not be a super heavy workload benchmark.

When runing memtest_vulkan (heavy on the VRAM, very light on the GPU), the card can reach over 3700MHz with a +450MHz offset (3900MHz limit). When I set a -400MHz, the clock goes down to a tiny bit over 3000MHz (3050MHz limit). I tried to go beyond +450MHz, but memtest_vulkan start to detect errors. Comparing the the screenshot I took of the runs surprised me. While the memory performance mostly stayed the same (within margin of error), temps went down, power draw went down like crazy and voltage went down. Everything else stayed the same.

This is why I set a -320MHz offset, it limit the clock to arround 3100MHz and since I'm gaming in 4K, the clock never goes close to it in most of the game I play. It goes over in older games running at 150 FPS++. In those games, I save power instead since my display support VRR and is limited to 144Hz.

I made an animated png because I think it's easier to compare the two results.

Yes, frequency will goes up on light load only, that's the point, to get last few digit. I have several profiles and use optimal profile for each application, I don't care about saving 50-200 watts if I have a success to cooling them.
Yes if you set minus frequency offset, you will get more flat FPS.
About memtest vulkan, it benefit more from VRAM clock instead of frequency clock, so your result is pretty normal.

Exactly. Just give it more power and go as far as you can, as long as it's cool. Too bad we can't use MPT. I was able to get my 6800XT from 250W stock to 330W with MPT and it was stable 24/7 :rockout:
It beat out a stock 6900XT but hey, it's something :roll:

Apology, I think I misunderstood what you meant when you said that:
not sure why now the frequency increase.
I thought you were surprised to see the card is reaching 3.56GHz when I saw that number on your screenshot :p That's why I showed my card could reach 3.7GHz in memtest_vulkan :slap:

Otherwise, regarding power draw, I agree with you guys, lets use that power! To me saving power is just a bonus in easy to run games.

I'd say my priorities goes like this:
  1. Stability
  2. One size fit all settings (I don't want to optimize per game or app, except for benchmarking ultimate score)
  3. Keeping GPU hotspot and VRAM closest to 80c, max 86c.
  4. Having in between 100 to 140 fps
  5. Keeping the system cooling not to loud
  6. Saving power only when having more than 140 fps
That tend to change overtime tho (summer vs winter)! :D
 
I want more power.... :roll:
I want to flash MY 9070 XT to THIS ONE, but unfortunately there's no BIOS here in the database. I'd also need it to be with Samsung Memory. Anyone? I'll buy you a beer! :toast:

There's also shunt mod but I don't know how much more risky that is.

This isn't 9000 specific per say but since the 9070 is a 1440p GPU I figured I'd test if AMD's VSR at 1440p provides any meaningful clarity difference above my 1080p native monitor. Apparently yes. Guess it's worth leaving on.

Yeah... There's no way I'm shunting my brand new, under warranty GPU :roll:
Doesn't say anything about flashing BIOS tho. And I have dual-BIOS with a bunch of older cards at home so no problem trying to reflash it if things go south. Basically the other card only has a higher TDP so that's it.

About VSR: it's great. In some games, there won't be much of a difference, but in most modern games that use checkerboard rendering, you'll see a huge difference in image quality. It's one of the first things I enable when setting up the drivers.
VSR on,
Radeon Image Sharpening On (to the max!)
Anti-Lag On (cause I play competitive a lot)
AF forced 16x
Texture filtering quality set to high and
Surface Format Optimization set to off

I may lose 1-3% of performance because of this but the image clarity (especially AFx16) makes a huge difference and there's no going back after you've experienced it.
Also, games with forced TAA - go f*ck yourself!

Hold up, those driver texture settings actually do something? Figured they were just a replacement for going through the same settings in the game itself.

Many games don't have the ability to turn on AFx16 for example (usually they max out at 4x), so yes, you can force some things with these settings. It's not like the Adrenalin is a replacement for in-game settings, but they can make a big difference sometimes. :rockout:
 
I use the same settings as @Thimblewad said, and because I've said many times that Adrenaline software is needed.
 
I guess FineWine is back. :cool:
Latest 25.6.3 drivers are 10% faster on average at 1440p than the release ones
 
So RX 9070 XT finally beats RX 7900 XTX?

It even manages to beat RTX 5070 Ti in multiple titles.
@W1zzard Will you do some rebench for RX 9070 XT with newest drivers? Performance increase is significant, so it should have it's meaning. Thanks.

Guys I'm back, and I'm back with even greater or the same, I don't remember delta hotspot vs gpu :D 35C xD

I've changed My motherboard, and with newer drivers and b550 the power draw in GPUz is more stable than before :)

390W? I want that so bad! :cry:

Also, hmm, 35°C on the delta is a lot... I used to have this issue on my 330W 6800 XT. After cleaning and putting on PTM7950 delta was 20°C.

Now on my 9070 XT at 334W delta is <20°C and it has the cheapest XFX cooler.

It's more like 360W with spikes to 390W. Gigablyat is not a great producer unfortunately. But I'm thinking of changing the thermal interface to thermal pads, and ptm on gpu die, but the card is a little to new to do that for now :).
The GPU is quite solid, but the thermal interface is a little under cooked.
 
Out of curiosity, how does the power/performance curve look? Do you get any noticeable performance increase even past 300W?
I will test it tomorrow, cause 110% powerlimit is just for torturing the gpu :cool: in My case :)
But I like tables so I will make one tomorrow with what would You like steel nomad, solar something or something other from 3dmark.
Stock setting, a little of undervolting, or some vram overclocking? :). (ps fans I will set to static speed).

I checked your card, I see it's the smallest one from the 9070XTs. Still, looks pretty fire and you get the nice 330W TDP, mine is stuck at 304 and unfortunately there's no way to flash a different BIOS (for now) :')

And yes, I understand not tinkering with the card now that it's new.

I paid 550€ for my 6800XT and I changed to PTM7950 after one week, so goodbye warranty :pimp:

This one was a bit too expensive. But it's not bad at all. At 25°C room temp. I get a max hotspot of 82°C and 1800-1900 RPM on the fan, the card is pretty quiet. But I do have 2x140mm fans below the GPU :laugh:
It looks a bit "ghetto" but it makes the whole setup quieter and I don't care too much about looks, as long as I have good performance.

Don't be too harsh please :laugh:

@io-waiter
Fans are 40% only gpu is 45%.
-50mV, 2700MHz memory
Port royal
90% tdp (300W around) 19399 (98%) hotspot 76C max
95% tdp (313W around) 19645 (99%) hotspot 79C max
100% tdp (330W around) 19828 (100%) hotspot 82C max
105% tdp (345W around) 20001 (101%) hotspot 85C max
110% tdp (363W around) 20160 (102%) hotspot 88C max

Steel nomad
90% tdp (297W around) 7461 (97%) hotspot 74C max
95% tdp (313W around) 7569 (99%) hotspot 77C max
100% tdp (330W around) 7665 (100%) hotspot 80C max
105% tdp (346W around) 7757 (101%) hotspot 82C max
110% tdp (362W around) 7832 (102%) hotspot 85C max

After testing it looks like I can use 90% tdp with minimal loss and with lighter loads that will get lower temps :)

Awesome, thx for the effort!
I agree, 90%TDP really looks like the way to go, those few percent is not worth it imho.

Note that it might be a little more difference if fans are on auto or full, but that will be a lot noisier gaming experience.

It won't I've got stupid fan setup :)
I need 3d printer to make some shims for cooler that I will mount in the back of the gpu :D

90% (306W) is what I've been using since the summer has kicked in! So far I'm dead set on: summer = 90%, winter = 100% (340W).

I bought an AsRock Taichi thinking the 340W BIOS was a good thing, but now I know it's like beating a dead horse. It's just not worth. If I could go back in time, I'd buy the cheapest 304W card and I'd be happy with it. 304W + 10% = 334W which is just perfect.
 
MSI Afterburner beta gets unofficial Radeon RX 9000 GPU support,.. I just started testing it tonight, so far everything is working fine.

<snip>
The shunt mod (or the alternative that buildzoid has shown in their video) is not very risky, unless you're not too good at soldering. The legs on the one/two ICs that you have to short are small, but it's nothing a steady hand and some flux can't help with.

Does it allow to increase the clock by a specific amount or does it set an offset like Adrenalin?

Sauce please? Maybe I'm itching to try :laugh:
