I just bought an Asrock 6900xt Phantom. I'm confused because of what others say online. Can XT chips on 6900xt reach performance with overclocks and things like Powerplay that Buildzoid showed? Will that improve and close the gap to these XTX chips?

W1zzard, will you be getting a Powercolor 6900 XTXH Ultimate for review?

Doesn't seem like it. Apparently their plan is to focus on influencers who show flashy OCs, that make people think the can achieve the same.

Comparing average FPS 4K to the EVGA 3090 FTW Ultra… I like this better than FE comparison, but slightly different review scenarios. See attached.

Ravenas and W1zzard is there a difference to junction Temps? For example do these chips stay cooler or do they reach their higher clocks with less crashing because of power limits?

I'm new to overclocking and I would like to get the most out of my card as I play in 4k. I haven't messed with Powerplay nor More Power Tool.

The applicable new cards are XTXH, binned chips designed to support 10% higher clock rates. Meaning they are cherry picked chips that are stable with higher voltages, ultimately delivering higher clocks. Moreover, the OEMs are designing the cards to deliver greater voltage throughputs.

Use Wattman in AMD driver suite to adjust settings, or if you are fine at settling at an auto overclock just select AUTO.

--

An example of a binned cherry-picked CPU is if you were to visit a processor overclocking forum. Some users can obtain better overclocking than others on the same chip with the same hardware. This can be referred to as a lottery, where the lucky buyer gets a binned chip. Whereas in the case of the XTXH, the OEM charges you more, however you are guaranteed a lottery pick and they guarantee the highest factory overclock, with potential to overclock high under a factory warranty.

ive got my hand on one of those cards,

sadly i can only turn 2675mhz gpu clock/2090 memory (fast timing) to pass timespy.

@W1zzard

what settings do you use in ungine heaven benchmark? (resolution?)

in your review you are at 2857mhz gpu clock/2160 vram.



does that mean my chip is far inferior?

Did you set power limit +15%? Otherwise OC will be held back

I'm using a custom scene in Unigine, nothing you can reproduce

I spent $1700 on my 3090. I bought it at MSRP. They are still available at MSRP through the Newegg shuffle only, although I purchased mine prior to the shuffle on Newegg.

Again, I don't agree that these cards aren't capable of good 4K performance when not using DLSS or Fidelity. They are and I use it every day on my 4K PC. Further, the proof is in the review. Look at the AVERAGE FPS across the suite of tested 4K titles. The exception is 1 or 2 games. One of them is Cyberpunk. People are trying to act like Cyberpunk is the bar for AAA 4K. Cyberpunk is an un-optimized bug-ridden game that hit that market way too early. I have the game.

Anyhow, I decided to sell my PNY RTX 3090 for a Powercolor 6900 XTXH Ultimate. There currently aren't games on the market which take advantage of more than 10-12 gb of ram, and I don't see them doing so over the next 3 years either. The performance outside of future memory limitations is better on my Powercolor 6900 XTXH Ultimate versus my PNY RTX 3090. My 6900 XTXH is auto overclocked to 2650 MHz.

Hi! Maybe I'm far too late to the thread, but I'm kinda considering doing what you did here. I also spent 1700 on a 3090 TUF OC, so, close to MSRP. And I am now thinking of swapping to the OC Formula XTXH. What is your experience so far? Should I make the switch? Any advice/tips?

I'm not (yet) into XOC at the moment, but I'd like to slowly build up towards that. I do enjoy tinkering around, benchmarking, overclocking, etc over the weekend, mainly with air/water setup for the time being, at times with chilled water, chilled air, morning winter air, and am not yet at the stage of hardware modding. I also use the GPU for gaming/work aside from the benchmarking/overclocking hobby of course. Do you think 3090 is an overall better keep for its performance, DLSS, RTX, VRAM, and overclock ability? Or do you think this 6900XTXH is the way to go based on your experience performing that switch?

Thanks anyway!

My experience has been great. The PowerColor 6900 XTXH Red Devil Ultimate is faster than my PNY RTX 3090 was (the Sapphire 6900 XTXH Toxic Extreme is really the top card of the XTXH in my opinion, unless you desire to invest in the PowerColor 6900XTXH Liquid Devil Ultimate with EKs water block). The VRAM is not really an advantage on the 3090 because ultimately you run out of shader power before you need the extra ram. The 6900 XTXH cards are available as well.

To answer your questions:

DLSS is a nice technology no doubt, but my prediction is that it fades out similar to gsync with respect to adaptive sync or freesync due to AMD's open approach with FSR.
VRAM, again 24 GB versus 16 GB is not an argument. You run out of shader power prior to running out of VRAM.
Overclocking... The XTXH is binned chips. You pay to win the silicon lottery. No power limit combined with lottery silicon equates to very good overclocking. This card will provide 2800-2850 MHz GPU with 2100-2150 MHz ram overclocked. The only card better in my opinion is the Sapphire 6900 XTXH Toxic Extreme Edition.

The XTXH is the best option hands down. It's faster than most 3090 OEM or FE across suite testing. AMD drivers are better than they have ever been so don't let people talk to you about that.

How do they bin GPU's without soldering them to a PCB? Is there some sort of test ball socket jig they use to temporarily mount them to a test PCB?

We tried a 6800XT and it was fine but lack of CUDA and faster performance on RTX cards in Premiere was why we didn't buy more.
Also availability; All 16GB RX-6000 cards were grossly understocked and overpriced here in the UK.
