Radeon 6900 XT

Sapphire RX 6900 XT Nitro+ overclock test on Youtube:

Only having 2x8 pin connectors seems to make no difference, looking at the 6800 XT reviews, where the Nitro+ matched or beat the Powercolor Red Devil in powerdraw.

I'm sure I read that with the two pcie cables and the slot will give you 375 watts. That should be plenty.

Afterburner is greyed out and won't let me change settings on the 6900XT, any idea why?

Should work but not sure if it's really worth the effort to O/C given the meager results. See here https://www.guru3d.com/articles-pages/amd-radeon-rx-6900-xt-review,31.html. There's a link on the page to download afterburner and it's dated 8/12/20

With my last three AMD cards I just used Wattman because it caused instability issues with 3rd party O/C software.

I never said AMD was bad at tessellation. I just shared my scores and I was happy with my 5700XT until I got the 3090. The scores I shared were with normal tessellation not extreme. Happy camper.

I'm not sure how the results of a 5700xt and a 3090 relate though. Did you not think we knew that the 3090 would be faster?

Not fully supported yet (Beta 2), at least not for me.

I replied because the guy said only Nvidia shills use these benchmarks. This is my first Nvidia card in 10 years but I used them benchmarks all the time with my Radeon cards. I know I'm a not a shill so I tried to prove him wrong. Obviously a fanboy I'm afraid. Move on.

Congratulations!

I know the feeling and i believe this gif is appropriate.

Luckily, getting my 6900 XT was easy as a big competitor of OcuK had them in stock for at least half an hour on the 22nd.

Very happy with my purchase.

It's been a long time since I've owned a GPU that can easily max out all the games i play at my resolution of 5120x1440 @100HZ HDR 10 Bit colour.

Thanks @LtMatt

Should hope to get it installed tonight for testing/gaming/tweaking.

#Stayathome.

Who said only Nvidia shills use these benchmarks? I said that there is no reason for an AMD owner to use a benchmark that focuses on extreme tessellation. Then someone who owns a 3090 made a joke : "benchmarks are for Nvidia shills". He talked about shills but it was a joke.
Extreme tessellation is so bad that when AMD users discovered you can get huge FPS gains by limiting tessellation in games like Witcher 3, Nvidia owners were angry because they didn't had a way to limit tessellation.

I personally don't believe you. Anyone with a AMD card knows that it's not designed for extreme amounts of tessellation. Move on.

Maybe my post got lost in translation. With my three Radeon cards I used Heaven and Valley as benchmarks but used NORMAL tessellation. Of course I knew my 3090 would spank the 5700XT I did it for a laugh. Jeez.

I never saw you post about it. However, on AMD cards the driver defaults tessellation to AMD optimized so you were never using normal tessellation. But some derivative AMD deemed appropriate (usually below 16x). With this enabled you were never using the game's level of tessellation. You would have to specifically know to set this to Override. Which again, I didn't see you post.

Does that option even do anything anymore? I thought it more or less became defunct after they got better performance over a period of time.

If you set it to custom you can control the tessellation and I used to set it to high. Seems you don't really know what you're talking about. Ignorance is bliss I guess. Move on.

It should since they never focused on improving tessellation. No one is testing their AMD cards in that benchmark anyway.
It is better to limit it in the driver anyway, who knows when Jensen will use it again to cripple another game?
Read here Nvidia users getting angry because they were left with 64x on Witcher 3 while AMD users could reduce it to 16x or even 8x and the hair looked the same.

So I did catch you lying. You're previous post states you used normal tessllation. No need to use custom. You would have said so in your prior post. Normal implied what the game/app uses which was, what I already said, Overide feature. Which you didn't know about either. You thought Radeon drivers defaulted to using normal tessellation when it doesn't.

All in the vain attempt to showboat about how well your amper does in tessellation in a RDNA 2 thread. Tisk, tisk.
Too easy.
Move on.

Finding one one would be a greater achievement than getting a golden sample

. I hope its going to be as fun as my vega 64 was to tinker with.

Your final MM post was funny

Let us know how far you can stretch the TDP. I really want to see if the additional connector allows more perf.
