The RX 6000 series Owners' Club

[AusWolf]

Tested another tune with 2,3GHz@1,125V in the driver suite and resulted in 2,28GHz@0,87V. Great efficiency with max 110W in power draw. I can just suppose that the firmware has algoriths and the die auto-adjust the voltage needed to keep those clocks no matter what max limit is set. I have no problem to that, instead I find it innovative and very efficient without losing any considerable performance (~90% of stock performance for just above half the power).

If you consider the fact that the 6750 XT is nothing more than an overclocked and overvolted version of the 6700 XT, there must be a crapton of headroom for making it more efficient.

Just got an asus 6600 for $270 CAD w/oi tax, probably put it away for a long while for son's BD. Never know what market is going to be like 7 months from now. But I am guessing all 6600's sold out and 7600/xt not out yet, and the cheapest card double what I just paid.

 

[W1zzard]

I just tested some tunes and observed that while I set the GPU voltage at 1V in the AMD suite, the GPUz reported 0.825V. And for another tune the AMD suite was adjusted to give 1.175V and the GPUz reported 1.043V. Any info on that deviation @W1zzard ?

From what I understand this voltage is the maximum, the GPU will choose the actual clock and voltage by itself, seemingly random from time to time

Where would be the sweetspot of 6700 XT voltage / Mhz / watt / fps wise ?
I saw the last 50 watts were squeezed out of the card to keep up with the competition, therefore losing a lot on the efficiency.

In my RX6750XT's case you can get ~97% of the max performance with tuning max clocks to 2,6GHz and voltage to 1,175V which results in 1,05V max and limits the power draw from 210W to ~170W (the power figure that AMD reveals through the sensors).

This 1,05V is an absolute max limit the goes only lower depending on the load. In another tune I tested and which retains close to 90% of the max performance, the 1,125V for 2,3GHz in the driver suite resulted in a 0,97V max limit that lowered the power draw to 110W max.

Maybe the 6nm helped in efficiency but I suspect that most RX6700XTs will be close to that.

I think that depends on your expectations. Personally, I just set a 60 FPS limit, and call it a day, as the card will draw as much power as it needs to achieve that.

My hardware setup is : https://valid.x86.fr/vawy9v
6500+6700 xt reference
1080p 165 hz mon + 4k 60 Hz tv

I used Radeon software and Rivatuner Statistics Server to monitor and a power meter connected to the wall.

I have set a Voltage Vmin/Vmax (mV) value of
793 - 1031
and a Power Limit (W) of
147 GPU
and temp target 65 C
in MorePowerTool.
what results is

in Cyberpunk

1031 mV
120 W
91-98 FPS on 1080p Ultra


in Forza Horizon 5
extreme preset

1031 mV
114W
126 FPS



The Division 2 1080p Ultra

Voltage 1010 - 1030 mV
2297mhz
135w
1080p ultra 93 fps

Division 2 pulled the most power - pulled 252 W from wall socket.

Temps are really low on the reference about 62-3 C°.
Pretty content with that.

I could probably go up to 186W with the stock reference setting in MorePowerTool but there is no point. Extra 10% performance for 80W more power from wall.
temps would be higher by at least 10C, as reference card isn't all that great.

To me it looks like best efficiency is under 100 watts of power.
I also came upon a twitter post showing watt per performance on a chart:

Ryzen 7 5800X, RX6700XT, 32 gb ram, 980 pro 1tb ssd X2, 570 tomahawk with Samsung Odyssey G7 27" I built it for 2K gaming, Haven't touched anything, running stock everything. Anything I should do or not do?

You can lower power draw, temps and noise by limiting voltage and clocks in the Radeon software suite. Test 2300MHz@1,125V. If stable that would lower power draw by ~70W and temps by 15C. Also you would keep the 90% of the stock performance.

Is 15184 multithread cinebench score good? Gaming only.

Cinebench has nothing to do with gaming, or Radeon 6000-series. You're in the wrong thread.

ty, I was reading as I posted. vs reading and asking questions, lol

Got my 6750 xt in today. I didn't realize it had such a tall cooler. The fans are 100mm. It almost looks like I could modify the shroud and install 120mm fans. That is probably not necessary.

 

[HD64G]

After more testing the 1.125v that translates into 0.87v realtime for 2,3GHz proved to be unstable in Troy Total War. So, I increased the voltage in driver to 1.15v and that ended being stable and resulted into 0.9v when pushed.

I am trying to enable Resizable BAR. I can't enable Resizable BAR unless I have CSM disabled. I can't boot into Windows from my NVME drive unless I have CSM enabled. Is there a way to resolve this?

Me thinks you need to turn your OS partition into a GPT one first. Look there: https://www.diskpart.com/gpt-mbr/gpt-format-windows-10-0725.html

 

[Nordic]

Is there any way to expand the power limit both up and down? It goes from -6% to 0%.

Thank you. That worked!

 

[Kabouter Plop]

GPT is required for uefi mbr is legacy that does not support resizeable bar

Though I'm still an RX 6900 XT owner, it will go into my 2nd rig. Main rig will get an XFX MERC 310 RX 7900 XTX which I'djust bought. You guys think I should start an RX 7000 series owners' club?

Sure, why not. That will be one heck of a second rig!

will FSR 2.0 work on my 6700xt? no word from them on Adrenaline updates (I asked)

 

[GamerGuy]

Sure, why not? FSR1.0 and 2.0 are meant for RX 5000 and 6000 cards (as well as other AMD cards, as well as nVidia cards), it's the upcoming FSR3.0 that is up in the air, though AMD is said to be working on it so that it'd run on modern cards, including nVidia's. IF AMD were to just focus on latest gen cards like the RX 7000 series (like nVidia, where only the RTX 4000 series which get DLSS3), they'd said it'd be easier and faster to support FSR3 with just one gen of cards.

For you to see FSR, the game has to support FSR1.x or FSR 2.x, then there should be an option in the game control panel for you to enable FSR1.x/2.x

 

[b0uncyfr0]

Which is the best card out of these three?

Gigabyte Eagle 6700XT
Sapphire Nitro 6700XT
MSI 6700XT MECH 2X OC

I have an FT02 - and investigating which cooler/heatpipes will work the best in vertical cases is be a nightmare but airflow will be top notch.

I intend to overclock as much as possible (plus apply any mods if available)

 

[3x0]

Nitro>>>Eagle>>>>>Mech

 

[b0uncyfr0]

Nitro>>>Eagle>>>>>Mech

Oh thanks. Why is the Mech last though? It seems the most compatible with my case
