AMD RX 7900 XTX OC Does Cross 3 GHz Barrier, But in Non-Gaming Workloads
AMD's Radeon RX 7900 XTX RDNA3 graphics card does cross the 3 GHz engine clocks barrier, but not in gaming use-cases, finds a ComputerBase.de article, in which the German publication compares the overclocking experience between the RX 7000-series RDNA3 and NVIDIA RTX 40-series "Ada" architectures. The RX 7900 XTX was found to hit engine clock speeds as high as 3455 MHz, but when handling the Blender rendering benchmark, and not typical gaming workloads.
The GPU could even be pushed to 3548 MHz with a power-draw of around 400 W, but it wasn't stable, the article notes. The top frequencies the GPUs could hit with gaming workloads were around 2.90 GHz. We could be happening with games is that more of the GPU's hardware resources are tapping into its power-limit (such as the memory controllers, caches, and other special SIMD functions, which could be impacting the engine clock boosting headroom. ComputerBase.de used a Sapphire RX 7900 XTX NITRO+ custom-design graphics card in its testing, which comes with three 8-pin PCIe power connectors, and a higher overclocking headroom than what the reference-design cards are capable of.

ATIAMD cards is the drivers, not the hardware. :DSimple if you have headroom for higher clock, why not milk public?
:twitch:
The real question though is if either team can put out a sub $500 card that is worth buying.
Chips simply have a best efficiency / performance curve. Once you start raising clocks the power consumption raises proportionally. Or the gains you get from OC'ing are minimal.
Drivers are fine from both camps. I have a Radeon 7900XT (couldn’t find an XTX) and I’m enjoying gaming with it. I’m sure everyone here is enjoying whatever GPU they have.
Stop using words like abomination. It makes us all look even nerdier and out of touch than we are. There are abominations in this world. GPUs are not among them.
Can you try for one nanosecond to not be a giga fanboy and say the most off the wall stuff possible ?
Its obvious that the cards werent ready for release yet.
Here you go, 8pins melting

Does that mean the connectors that amd has are melting? Youll find hundreds of threads with 8pins melting. Try to hide your bias man
You saying your drivers dont crash is irrelevant. My 16pins didnt melt either, does that mean no ones did?
Or do you happen to have a large family, a huge house and a need for plenty of gaming PCs?
The thing is some 16pins melt, you said drivers "constantly" crash. It would be pretty stupid if I said connectors constantly melt wouldn't it ? Because they don't. Well, saying the drivers constantly crash is just as stupid and untrue. See the problem ?
How do I know drivers crash on amd? A read on amds owners thread in every single forum on planet earth suggests that. HDR not working? Again, the internet is full of complaints about this.
And they even have the gall to ask over 1,5k ;)
And on top of that, AMD 'just wingin' RT keeps them within spitting distance now on their latest series., go figure, without all the nonsense around it.
The whole state of GPUs is abysmal right now; even Nvidia's stack relative to Ampere is a sorry state of affairs.
You don't know what the word "fact" means just as you don't know what "constantly" means. No, it's not. Define "the internet" and "full", once again you use expressions that mean nothing and can't be proven. Considering you misspelled it so badly the first time around I didn't even knew what you were talking about I doubt you're sufficiently apt at determining what works and what doesn't.
Especially since you don't have one. I do and to your dismay I just checked and HDR works fine.
By the way I am surprised you are so thoroughly educated on this subject. Do you do anything else besides scouring the internet for obscure problems on AMD cards ? If you'd ask me what problems there are on Nvidia I'd have no clue besides something huge that was covered in the media like the power connectors thing, though I am sure there are plenty. So are you still sure you're not a fanboy ? Like 100% sure ? I am still wondering because you're not very convincing.
