The RX 6000 series Owners' Club

I am. It's a lot quieter than I expected for a basic Asus Dual model, and it uses a lot less power (literally about 90W less, according to hwinfo) than the RX 570 in the games I'm currently playing, which are capped at 60fps by engine limitations. Under a folding load, the hotspot is mid 70's and the card is still very quiet.

It's amazing how efficient a more powerful card can be when you cap your frame rate. Just like a more powerful car uses less fuel to keep the same speed.

I tested my 6750 XT against a 6500 XT in Kingdom Come: Deliverance, and to my amazement, it uses less power to keep my FPS cap.

Touching that magic 3GHz in Superposition with a 6600XT. Fastest card on air, although not a lot of people are submitting scores.

 

[AusWolf]

I just did a little experiment on efficiency. If I lock the 6750 XT's GPU clocks to 70%, GPU power consumption in Unigine Superposition will be around 95 W, which is similar to a 6500 XT. Performance and the final score, on the other hand, are on par with a 2070 that has a TDP of 175 W (with 130-ish W GPU only power)! Where are you, green-blooded efficiency maniacs now?

Anyone having coil whine issues while scrolling webpages for ex. (non 3D load)? I found that leaving the minimum frequency to 500 when configuring the OC profile fixes the 2D coil whine for me. >1600MHz min freq I can faintly hear the whine.

I hear some coil whine on my Powercolor 6800 XT but not my Sapphire 6600 XT under similar loads to what you describe, low load but high frequency. While booting up and the card maybe is doing some internal validation? But I leave all my cards to clock down normally under light loads so by the time I'm at the desktop there's no whine.

Lexluthermeister has a long thread here about how to fix coil whine if you're interested. My favorite coil whine (it's a thing!!) was actually CPU noise from my Apple IIgs which had a very chatty processor. When I got a ZipGS CPU upgrade it was mercifully quiet and much faster, a nice bonus.

 

[GamerGuy]

Honestly, I dunno if I'm not sensitive to coil whine, or if I'm going deaf, but I've never come across any card, both AMD/ATi and nVidia, that has a coil whine issue....not even once! Didn't know that there's such a thing actually .....

Edit - BTW, got a GPU brace/stand for my RX 6900 XT, noticed that it'd sagged a little without the brace, I did read that sagging can cause damage so I'm erring on the side of caution. Didn't cost much, so it's a cheap fix.

 

[Deleted member 230939]

It's a thing, my ASRock Phantom D OC 6900 XT had it at high FPS.
My ASUS TUF 7900 XT has it at any FPS but it presents louder the higher the FPS, I am considering doing the glue trick to fix it.

yup only time I've ever heard coil whine was high fps in mainly ingame menus not so much now as the games I play have been patched to stop it from reaching stupid high fps in ingame menus

That places it right in GTX 1660 Super territory!

That is rather impressive.

Nah, the 1660 has a total card TDP of 130-something W.

The GTX 16 series, is infamous for the low watt limit, making it difficult to OC the core. The GTX 1660 Super, is the meme of core OC'ing being almost worthless and VRAM OC'ing being king.

The 2070 is the same. It runs into a power limit even at stock. I think this is just how modern GPUs and CPUs work.

Is being so aggressive with the fans necessary?

Almost 2800 MHz on a mild 1035mv relative underclock (means it reaches the same 1.2v max for a 6950 XT a bit later in the MHz curve) means a lot of heat being generated, especially if playing with FPS uncapped so less chance of temporary lower power/heat generated. But yeah, the sound might be a trifle loud.

Sure, but I mean, you don't need 100% at idle / low load, do you?

well i tell ya when ur at the cliffs edge its best to keep it cold as possible ...... for me my pc is 6 feet away i barely here that itll place first and second with a 4070 ti anyday i credit myself with buying a really great psu then i thank the psu for letting me run those clocks not too shabby for a now 11 y/o psu

Sure, but I mean, you don't need 100% at idle / low load, do you?

75% not 100

So fun little update from the new rig: it looks like i've finally found something to max out the 6950 XT. Since getting my new monitor and upping Cyberpunk's resolution (to QHD) I've found that the 6950 XT constantly draws a full 325W (and 10GB of VRAM!). But it's still maintaining a smooth 60 fps in game. Really happy with the card I have to say and I'm glad I've hit that ceiling so I can see its capabilities.

After going to QHD I don't think I have a desire to upgrade any further. Games are gorgeous at QHD and I don't think UHD will end up being worth the performance trade-off.

 

[tpa-pr]

Checking in again, I have started playing with undervolting! After some late-night tweaking I have settled on the following for my 6950 XT:
GPU:
- Min Frequency: 1225Mhz
- Max Frequency: 2625Mhz
- Voltage: 1125mV

Mem:
- Memory Timing: Fast Timing
- Max Frequency: 2350Mhz

Fan:
- Zero RPM: On
- Temp: 30C (Speed: 35)
- Temp: 50C (Speed: 40)
- Temp: 70C (Speed: 50)
- Temp: 80C (Speed: 65)
- Temp: 90C (Speed 75)

Now I'm a layman at this so I'm not sure if they're good or not, but it has let me gain about 10fps in Cyberpunk's benchmark and Remnant II now holds a steady 60fps with lower power draw and heat. The GPU hotspot hovers around 90C (down from ~100-105 when playing Remnant II for example) when under max load and power draw has boosted up to ~350W or higher.

The only downside is I can't get Time Spy to run, so I suspect it's not stable. BUT, I also can't get Time Spy to run on anything but stock settings. Superposition passes without a hitch and none of my games exhibit any issues (yet) so I'm keeping it for now. Obviously far more testing is required but so far I'm pleased with the result.

That being said if anyone has any suggestions, please let me know! I'm open to expert advice.

Delete 3DMark and redownload it. Yeah the whole thing I think, can you just delete one test at a time? I would get a consistent crash on the second of Firestrike's GPU tests on one machine until I deleted the suite and re-downloaded. Coincidentally on my main rig now Unigine Valley crashes every time even when very underclocked. On 3 different cards. I'll reinstall at some point...

Noted, I will try exactly that and see what happens, thank you.

Alright, after re-testing I am quite certain that my undervolt is stable, it is just Time Spy that is playing up. I have reinstalled the entire 3DMark suite and the issue persists, yet every other 3DMark test and any other tests I can throw at it (Unigine, OCCT etc) all pass without a hitch. Even Speed Way from 3DMark works just fine. What an odd quirk.

Wish my 6700 XT could do the same. It has a massive cooler and temperatures are fairly low and could be even lower if I replace the thermal paste with something of decent quality but OC-wise it's still a dud. Only +50 MHz beyond stock.

After having a 6400, 6600 XT, and a 6800 XT I can say that I've found my 6700 XT to be the runt of the bunch. Observations:

Sapphire Pulse 6400: this is the tiny HHSS one and it's a great GPU to drop into any old PC and get gaming. In the games I play, the 4-lane PCIe 3.0 (all old PCs) 'limitation' seems irrelevant. Runs 2306 MHz and 0.916V with no OC capability.

Sapphire Pulse 6600 XT: 1.15V nominal but underclocks and volts like a champ with minimum voltage in the 0.68 range so it can run at 30W in low demand games (Rocket League). Also overclocks well to around 2780 MHz (actual, not in Adrenaline)

Powercolor Red Dragon 6800 XT: 1.15V nominal but underclocks and volts OK considering it's extra resources but only to about the 0.75V range and minimums around 70W (RL). Overclocks to around 2650 MHz IIRC, haven't done this in a bit.

Yeah but the 6700 XT. I should like it more but I like efficiency and it's not great at that.

Powercolor Fighter 6700 XT. 1.2V nominal but underclocks itself out of the box worse than the above cards thanks to high power draw. Voltage 0.86 minimum keeps power draw at 65W minimum while gaming (RL), not much better than the 6800 XT. Takes careful matching of voltage and MHz settings to eke out about 2600 MHz, bashing against the +15% power limit.

Considering the price I paid ($300) it's probably the best deal out of all my cards as the 6600XT was bought on the downswing of mining overpricing but still significantly inflated. But that one behaves well in the voltage and frequency department as do the other non-6700 XTs.

Yes the 6700 XT is a PC Fighter, the lowest-bin and yes, it was only $300 but I was hoping for about 45W in Rocket League and it simply doesn't do that. However I've been using it for a few weeks now and I'm getting used to it's behavior and where to run it for max efficiency and it's ok, especially considering the price. I'm trying to get a lot of experience with it and then swap in the 6600 XT and see how the feel changes, especially the reduction in performance along with the reduction in power/heat.

Apparently I need to try out the 6800 but I'm done, I think I've tried enough of these and it's all to support my gaming so it's not like it's been a trial or anything!

Random side note: I picked up a used $120 Pulse 5600 XT from eBay for an Optiplex build and it's great for its use, also with good power behavior so it was nice to get that perspective along with the 6700 XT.
