They have a lot of fixes to do with their drivers but that’s a known already.

another new issue has been found, I've lost count now of all of the issues.
Mesh Shading is a DirectX 12 feature; something went wrong and RDNA3 has less than half the performance of RDNA2 when doing mesh shading
Ummmm.....
At least they've started acknowledging it's broken. They just acknowledged the idle power draw on rdna3 is broken, no eta on a fix but issue is acknowledged at least

Just need for Nvidia to acknowledge the 4090 power draw problem....or are they both related to 5nm
Yeah it looks very broken. And why would it be related to a process node?
4090 power draw:
Multi monitor idle: 29w
Video playback: 26w
60hz vsync game: 76w
NVIDIA GeForce RTX 4090 Founders Edition Review - Impressive Performance
The NVIDIA GeForce RTX 4090 Founders Edition offers huge gains over its predecessors. It's the first graphics card to get you 4K 60 FPS with ray tracing enabled, and upscaling disabled. Do you prefer 120 FPS instead of 60? Just turn on DLSS 3.
7900xtx power draw:
Multi monitor idle: 103w
Video playback: 88w
60hz vsync game: 127w
AMD Radeon RX 7900 XTX Review - Disrupting the GeForce RTX 4080
Navi 31 is here! The new $999 Radeon RX 7900 XTX in this review is AMD's new flagship card based on the wonderful chiplet technology that made the Ryzen Effect possible. In our testing we can confirm that the new RX 7900 XTX is indeed faster than the GeForce RTX 4080, but only with RT disabled.

"Like previous hardware generations, shader pre-fetching is supported on RDNA 3 as per [gitlab link (opens in new tab)]. The code in question controls an experimental function which was not targeted for inclusion in these products and will not be enabled in this generation of product. This is a common industry practice to include experimental features to enable exploration and tuning for deployment in a future product generation." — AMD Spokesperson to Tom's Hardware.

They say it works fine but didn't say why they turned it off, an important question when you consider the fact that it was turned on for RDNA2.
Its also not that experimental, some developers, even some game engines are already using it.

Shader Pre-fetching is a way of pre loading shaders to cache them so the don't need to load in on the fly, it stops hitching and stuttering, you would use it sparingly but where you would use it where there is a high density of shaders needed to be loaded constantly.
Like Imagine an asteroid field with a high density of rocks visible for hundreds of KM, you would want them preloaded or you would get a lot of visual popping and stuttering.
Its why i put this video up, if you were wondering, CIG do use Shader Pre-Fetching.

Untrue.
Our email stated you can wait as we are securing additional stock or you can change your order to another alternative card or request a refund.
We also have more MBA XT on the way and more XTX to cover the over sold back orders.
As the saying used to go don't believe everything you read in the papers, guess now its the same for social media and youtube.
No worries all good to clear it up
He made the claim in his latest video and also on his twitter

I agree with this guy.

Lots of acknowledged such wow.

The whole reason i didnt jump in on release day was the reviews the previous day. I wanted AMD to blow Nvidia away for a change with a new design for the future at the same price point as the 6900xt but with the performance of being smack in the middle of 4080 and 4090 maybe 4080ti performance, but it matches the 4080 over all and worse on RT.
I had my finger on the button to purchase when gibbo released the sapphire cards 10 min's early but just couldnt push it, the reviews were not glowing in the XTX favour, So left it. Thought well i will stick with the 6900xt. Also the 4080 had been in stock for days but after the reviews they soon went out of stock
but are back now. Then the 4090fe came into stock, so i grabbed one. didnt really want to spend that much but gives me 2 years until next gen and i can play what ever i like at 4k.
AMD i really wanted the XTX but your launch data V review data was just to far apart for my liking.
lets hope the fine wine drivers improve it, and RDNA-4 gets the kinks worked out for true performance gain's.

I think it's not too wise to buy any components on release day whether it's gfx cards or chips. There's nearly always problems on a first issue. Best to wait for revisions to come out.
Remember all the problems with the first issue release of 3000 Nvidia and overheating due to poor thermal pads?

So rtx 3090ri ray tracing is rubbish now??
Associate
I dont think its rubbish when AMD's flag ship XTX cant beat it with RT in some games, plus with DLS it's still a great card, if purchased 2nd hand below XTX value makes it a good card still in my view with a lot to offer.
there is no confirmation of any hardware issues with the 7900 series of cards.
what we have here is a bunch of FUD being repeated on the internet.
if someone on the OCUK forum has a hardware issue with there card, that's the time to take notice. Nobody has posted a hardware issue as of yet?
Soldato
Apparently so. The RT promoters that could just turn down a setting now have fled that nest. It is still niche and in too few games to be a must have feature, obviously on an enthusiast forum it wont go down well but the point is it shouldn't bump prices up especially 2x for the 80 class model, complete joke.
Might be a different story in 2023 if nvidia slash the price. Back to the 7900, again its release day pricing and they need another 20% haircut to entice the normal gamers attention im afraid. If all the flaws are true they will have a lot of work on their hands building trust.
