Big Navi (RDNA2) discussion

[watzup_ken]

quite confuse for me, reddit some said a huge different RT compare to non RT, but HDR look like benefit more on experience of gaming. But HDR you really need to have a monitor that can goes up to 1000 nits to enjoy HDR. Best experience still with OLED monitor.

I feel that is the general misconception about HDR. You don't need 1000nits to have a good HDR experience. The trick is the blacks need to be black, and the bright areas need to be bright enough. If the screen is able to produce pitch blacks, even 400 to 500 nits is contrasty enough to have a great HDR experience. So OLED is usually the best option.
RT and HDR are really 2 different kinds of eye candy. But I feel HDR is more impactful because actually don't need to hunt for the difference. If you have a device that uses an OLED panel, and you just play a HDR content, you can immediately tell the high contrast between the blacks and the whites in the video. Whereas RT, you generally need to hunt for differences in shadows, lighting and reflections, and without trained eyes, you likely can generally only tell the differences if you compare it side by side. At least this applies for me.

Just a minor sharing. My nephew bought a 2nd hand Powercolor RX6950XT Red Devil from my friend last 2 week, used it in his mid tower Corsair case with no front mesh. He gave me call and asked for solutions, cos his GPU hotspot was hitting 100 degree and fan spinning at loud full speed all the time. I gave him few solution by changing casing, repasting and deshroud and he agreed all, including killing his graphic card if mod failed... .
Went down together with him to SLQ to grab his Lancool 3 casing on last Saturday, then he went to grab 2 spare T30 fans from 2 of my friends *Fainted*, a bit regret of sharing a joke with him in the past while together with my friends gathering that Asus Noctua 3070 might be cooler if T30 being used. Nevertheless, completed all the swap and mod on Tuesday, fired up and everything works well. Below are the result of the power load and temp with the T30 fans running on middle performance setting (2k max rpm). Hope i did everything right and not killing his graphic card any sooner, fingers cross.

The paste a bit caked out on right one corner.

Whacked his game in Overwatch under epic setting test. Full power load non stop at default 0% Powerlimit 325W for near 10 mins, max temp hover around 74c under aircon 24c ambient.

Are you using a fan speed controller if you installed the T30s on the GPU cooler? If so, I tried that in the past, and I think even at say 70% to 80% of the 2K RPM, it can still be quite audible. But the good thing is that it is not annoying.

I am not using any fan speed controller for my nephew graphic card. Both fans was connected and controlled by the graphic card with DIY 4 pins wire adaptor, 1 side is a female fan connector, another end is the smaller male gpu connector.

recently changed from gtx1070 to a 6700xt, i noticed that my gpu utilization is unable to hit 100% in my games, and im getting about 3x lower fps than my gtx 1070. Is there anyway to resolve this issue?

 

[Koenig168]

3x lower? This is strange.

Did you remove the Nvidia drivers with DDU before installing AMD drivers?

 

[Elijahonli]

3x lower? This is strange.

Yup removed it using DDU in safe mode. Installed the AMD driver after booting back to windows. My VRAM Clock speed is showing 0 as well. GPU utilization while running my game is only at 50-60% getting about 50-60 fps. Previously my gtx1070 was comfortably getting 170+fps

i tried setting performance power plan already but the result is the same too

 

[Koenig168]

Suggest you test with other games and see if there is still the performance hit.

btw is this a new card? from China?

did u encounter any errors while installing? are u able to open amd software normally and check the performance tab to see the performance metrics? may be a throttling issue, do keep an eye on hotspot temperatures and clockspeeds of both the core and memory in games as koenig suggested.

No errors were encountered. I tested the card with 3D Mark Timespy and got a GPU score at ~12400 which seems about right for a rx6700xt

The part i dont understand is that in menu the gpu load is 100%, however actual gameplay the load is reduced to 60-70%

In menu:

Actual gameplay:

Yes i know the GPU hotspot temp is damm high, but that is something im trying to resolve. It shouldnt cause my actual game to be so slow. Furthermore, in actual gameplay the temps are fairly low, gpu usage is low, and power is only 1/3 of whats supposed to be in the menu ???

I have tried resolving the issue with MPT with the steps from here: but it dint help

Cap your fps to a reasonable level on the driver level, like 60 or at most your monitor refresh rate(144?)... This is important for certain games as it can fry your card in their title menu.

Enough power for the card or using correct power pins? What's your PSU. TDP is 230W vs your old card's 150W. The game is running only at 56W, suppose to be around 130~220(closer to this).... Also check your power management plans for both windows and AMD control panel. Win 11, has a graphic settings that toggle between different graphic chip, you can also check that and even force use of the performance card.

110c hotspot is basically tjmax, that clockspeed in menu is actually lower than base, so it is likely throttling. where did u source the card from?
another thing u can check is whether u have any frame caps in place, either in game, in rtss or in radeon software (under radeon chill). do u have games other than this one and 3dmark to see if this behaviour is reflected elsewhere?
another thing u can monitor is cpu utilisation, especially of individual threads to see if u also inadvertently have a cpu bottleneck (not likely, since ur 1070 was faring well but still something worth checking).

Thanks for the advise will try and cap it to my screen refresh rate (165). Power pings should be correct, i used the same cable that plugged into my 1070 (8pin) and the 2nd 6+2 plug from the same wire into the 6700XT. Power plan is currently using amd ryzen high performance. Tried High Performance as well but no diff. There is only 1 GPU in my system, no iGPU

card is a reference model from TB. hitting hotspot and some level of throttling is kinda expected. The game framecaps at 300fps, which is shown in the first screenshot (menu hitting 240+fps) , radeon chill is disabled. CPU bottleneck is not expected here as im running a 3700x. 3DMark can hit its max performance (~12400 GPU Score). Dota2 1440p max settings, I am able to hit ~254fps with vsync off

I saw a couple of threads that are experiencing similar issues to mine
https://www.techpowerup.com/forums/threads/new-gpu-less-fps.304020/https://www.overclock.net/threads/rx-6000-cards-are-disgustingly-bad-for-old-games.1805753/
Im wondering if its a AMD issue rather than "china" card issue.

 

[NightRaven49]

i used the same cable that plugged into my 1070 (8pin) and the 2nd 6+2 plug from the same wire into the 6700XT.

better to use separate cables for 2x 8pin.

hitting hotspot and some level of throttling is kinda expected.

amd reference coolers dont suck like they used to when they were all still blower designs, the 6700xt cooler is more than enough to tame it. u should probably repaste it.

CPU bottleneck is not expected here as im running a 3700x. 3DMark can hit its max performance (~12400 GPU Score).

im inclined to agree, though checking it for good measure wont hurt. 3dmark gpu test definitely wont have cpu bottleneck because it is designed to specifically avoid it.

u could try enabling radeon anti-lag for the affected games. i did also come across a similar issue for previous gen 5700xt, maybe u could give it a shot:

 

[KYZT2021]

newegg got MSI 6800xt going for 780

 

[xonix]

I am using the auto one click undervolt setting in the AMD drivers menu. There is no issue when playing games but it will always revert to default whenever I reboot/shutdown PC normally. Is there any solution or workaround for this ?

EDIT: google'd and found a post that suggested disabling fast boot. Seems to work

I see no purpose for rebranding the cards. If they are not selling for whatever reasons, associating the card with Rabbit at the end of the year is not going to see a miraculous increase in sale. If they really want to clear out these RDNA2 cards, their only way is to lower prices during the year end sales. These are decent cards as compared to say Intel A770/750 and even the overpriced RTX 3060/3070 cards. So I think there is a market, but buyers are being squeezed due to inflation.

The purpose is the same as the Intel 14 series. Make the number bigger and (a lot of) people will think it is better.
