The Radeon RX 6800 (XT) Owners Thread.

[coach7290]

I actually have exactly the same setup as you. I have the 9900K at 4.9Ghz and have the Powercolor 6800XT Ref. Model. I'll install the game shortly and let you know what FPS I'm getting on the same settings.

AFAIK, the 9900K was the fastest gaming CPU until the 10th Gen Intel/Ryzen 5000 series were released, and I think it outperformed the 3000 series Ryzen, but not by much.

According to a SAM benchmark from Eteknix, Metro Exodus doesn't really benefit from SAM at all :

I've noticed myself my card benefits more from earlier drivers (Jan/Feb 2021) and not the latest ones. I get better overclocks (up to 2.7Ghz), less random freezes and black screens, and looking at the date of the video you referenced, he's probably on some of the earliest drivers released on the 6800XT, so perhaps the drivers are connected.

He also may have faster RAM. I've watched a couple of B4B's videos in the past, and I'm sure he uses 4400Mhz C18/C19 Patriot Viper Steel. It wouldn't explain the 15FPS gains but it may explain around 5FPS if you're using 3200-3600Mhz higher latency RAM in comparison. From the video, it looks like he's getting anywhere from 80-100FPS depending on what's being rendered.

In any case, I'll let you know as soon as I can get the game installed and can test for you.

Thanks very much for the detailed reply, looking to see your results then . I thought about the ram, those Vipers are really exceptional, especially because he lowered the timings even more apart from the 4400mhz. I got on my side "just" 16gb of Vengeance pro 3600mhz (default timings). Another thing to note, my gpu is struggle with vram overclock, and I got worse performances if I increase the vram clock over 2110 ( while he is maxing out the slider to get those 2138 ingame).

How do you know which part of the game he is benchmarking though?

Not sure if I got your question right, but that video it's exactly the beginning of the game, so It's quite easy to follow along using the same settings and go through it.

I'm sorry, i clicked the link xenosys posted by mistake.

Yep, so just tested the game. I've set the resolution to 2560x1440p, Setting at "Ultra" with Raytracing at "High" and everything else left as it originally was.

My card is OC'd to around 2.65Ghz drawing around 320-330w (using MPT) and for the first 10-15 minutes of the game, I'm getting anywhere between 85 FPS in the high intense scenes and 105FPS in others, so I'm probably 2-3 Frames better off than B4B in his original video due to the additional core clock speeds. My VRAM is also a little delicate and I need to set it at 2112Mhz as it starts to lose performance and green screen if I set it any higher. I don't think the additional 30-40Mhz on VRAM makes all that much of a difference anyway.

What sort of FPS are you getting in your playthrough?

I played this game long time ago, I've just reinstalled it to test it within the beginning following that video so I'm not sure How much consistent the fps will be through the entire game. Anyway thanks for your feedback, there's for sure something wrong and i will investigate the issue. What graphic score are you getting off timespy?

No problem. My highest has been 20950 but that was just to bench. My 24/7 score is about 20500.

Wow, that's a very nice score. Can I ask you to show me your tuning panel inside the oc tab? I'm getting around 19230 on Timespy.

Here's the 3D Mark result : https://www.3dmark.com/spy/18370121

It's been a while since I had it set up in Wattman, but from memory, I had the core clock set between 2650 and 2770 and was pulling in an average of 2.7Ghz during the benchmark. The VRAM was set to 2120Mhz, Fast Timings, using the slider and the PL was +15%. This gave me the score of 20900.

I was also using MPT to boost the card's power and current limit. The power limit was 340w and the TDC Limit GFC was 360 with a SOC Limit of 60.

Bear in mind, that this is under water in a custom loop, not on air.

Thanks a lot. Did you undervolt the card or using mpt with undervolt doesn't make a lot of sense?

The voltage in Wattman was 1085mv, but once you hit a certain frequency I don't think it matters as the card effectively takes what it needs to support whatever clock range you want to set it at. The voltage was pretty much nailed at 1.15v throughout the benchmark when looking at it through GPU-Z. I've never undervolted the card in MPT before.

FYI for all 6800XT owners. Just played through the Resident Evil 8 Demo on Steam. Had my card OC'd to 2.675Ghz, settings maxed out at 1440P with RT set to High, and was pulling in anywhere between 110-130FPS depending on what was being rendered.

On 4K, with the same settings, the FPS dropped to around 90-100FPS.

Excellent performance on the AMD cards with the REengine, and with decent RT to boot.

My friends!

i finally got myself a new gaming rig

coming from a vega 56 to 6800xt my golly the performance !

i got the gigabyte version, had abit of an aggressive can curve which i quickly addressed

Hi guys, I'm reading often that the amd 6xxx series benefits from having the pci power cables distints from each others instead of having only one splitted in two.Is that true? Which kind of gains you would have?(temps,performance, power efficency,oc capabilities). Now I have my gpu connected from only one cable splitted in two.

I feel like this is less of an AMD 6000 series point and more just you should typically always use separate cables from your PSU to your GPU.

I could be completely or it might have just been that it was an absolute no-go to use split cables with older GPUs / PSUs from years ago but I'd always say you should be using separate cables coming from your PSU to your GPU.

Hey, random question but has anyone tried connecting five displays to their 6800XT? Wanna add a 5th monitor but it's on the wall in another room so figured I'd check working before trying.

I feel like this is less of an AMD 6000 series point and more just you should typically always use separate cables from your PSU to your GPU.

The issue is basically that many PSU GPU cables have two 6+2pin connectors on them, and almost zero of them are intended to be used in 8pin+8pin mode, simply to give you the option of which of the two to use in 8pin mode on a GPU that has 6pin+8pin. It probably wouldn't be an issue with a 6800XT but back in the day there were a number of high powered GPUs that when connected via an 2x 6+2pin cable in 2x8pin mode could melt the modular connector at the PSU end as overclocked they could be pulling 400w+ through it (this was more common with Superflower PSUs that used their silly square 9pin modular connectors, or cheap PSUs that didn't adhere to the correct gauges/rating/etc).

Just a update on my issue
The card was sent back to the place I bought and they have confirmed the issue but due to no stock they have had to send it back for rma so will prob be waiting a while for a new one

Got a new 6800xt but it is showing a black screen
