Windows 10: 6800 XT massively underperforming in Windows, runs fine in Linux.

I bought 6800 XT and naturally benchmarked it for testing. Under Windows it's performing worse than my previous card. Under Linux it runs perfectly fine. I DDU'd my nvidia drivers before putting in the card, then installed the latest drivers, chose 'performance' in Adrenaline and got a Superposition score of 9,321. A 6600xt scored 17,000 on my system for reference. I disabled all Radeon and Adrenaline tools / clipping, and it got around 14k. I wiped the drive and reinstalled Win10, same results. I wiped the drive and installed Win11, same results. I've tried disabling rebar and 4g decoding too

Question Is a 6800 XT with three connectors better than a 6800 XT with two?

Hello! My name is Mostafa, and I’m an independent advisor and a long-time Microsoft user, and I will try my best to assist you with this so that you find a satisfactory solution.

The ASRock Phantom Gaming 6800 XT and Sapphire Pulse Radeon RX 6800 XT are similar in performance, and differences in overclocking performance could be due to variations in GPU silicon quality. The card's BIOS determines the power limit observed and is not related to the number of power connectors on the card. The number of power connectors on a graphics card does not determine its performance.

I hope the above steps helped you. In case of additional questions, reach out back to me, and I will be happy to help and try my best to resolve your issue. Thank you.

Best,

Mostafa

Question Is a 6800 XT with three connectors better than a 6800 XT with two?

I had an [ASRock Phantom Gaming 6800 XT](https://pg.asrock.com/Graphics-Card/AMD/Radeon RX 6800 XT Phantom Gaming D 16G OC/index.asp) with 3 connectors, but I was having issues with it and returned it for a [https://www.sapphiretech.com/en/con...n/consumer/pulse-radeon-rx-6800-xt-16g-gddr6) with only 2 connectors. Is the Pulse worse than the Phantom Gaming then, or are they the same? I did get the Pulse for $15 less than the Phantom Gaming which is something.

I was able to OC my ASRock to a minimum of 2450, a maximum of 2550, a VRAM frequency of 2124 with fast timing, and undervolted to 1000mV. For my Sapphire, I can only OC it to a min of 2309, a max of 2409, and a VRAM frequency of 2112 with fast timing on, and undervolted to 1100mV. Is this just because of the silicon lottery, or is this because the Sapphire has only 2 connectors?

It seems to be reaching the power limit when I run Time Spy. The PPT limit percentage gets to 99% to 100% when Time Spy crashes, but it also gets to that point when Time Spy doesn’t crash; I suppose something else is causing the crashes then like the silicon lottery. Additionally, the PPT limit is 312.8W anyway when I set the power limit to +15% in Adrenalin, and I heard the most I can get with 2 connectors is 375 W; I don’t plan on using MPT to raise my power limit even more, so that seems to be unrelated to how many connectors I have anyway. Is this actually related to how many connectors I have, or is this limited by the BIOS?

 

AMD XT non XT Graphics Cards 6700? 6800 6800XT 6900XT

XT non XT thread for AMD users
6700 Maybe 6800non XT 6800XT and 6900XT
Prices for each tier includes
6800 Comparable to 2080ti $579.00
6800XT Comparable to 3080 $649.99
6900xt Comparable to 3090 $999.00
All cards are 300w TDP 150w lower than Nvidia's 3090
What card are you looking for or are you staying with team green Nvidia ???

These prices are MSRP but keep in mind a $50 upcharge might come with these cards
