I just saw this recent article on overclock3d dot net stating that CUDA now runs on AMD GPUs as well (here)  and I wonder if this would allow to use such cards with Poser, as Blender 4 can.
This would force nvidia to sell their cards at a more reasonable price, don't you think so?

"While ZLUDA cannot run Nvidia Optix code on Radeon graphics hardware, it can run CUDA binaries without any changes."

Nothing is going to make Nvidia sell their cards at a "reasonable price".  Too many folks are willing to pay $2,000 for a top tier video card.

This is why I have lobbied for dumping Optix and going with the AMD ProRender engine.

The ProRender engine has been integrated into a number of high performance programs like Solidworks, and Plug-ins are available for 3DS Max,  Blender, Maya, and Unreal Engine. 

It will run on any RDNA gpu, so even a $130 RX5700xt from Aliexpress will get you going.

The software is Open Source, and AMD is willing to work with anyone.

That could be a very interesting solution, indeed. If only....

Yeah - and it isn't like they don't have a major university with a Computer Science department that is about 10 minutes away from 'Rosity World Headquarters.

This will more than likely lower the price of the AMD cards... Cuda translated on AMD is faster than HIP ROCm on AMD.....

Which is pathetic at best for AMD and HIP ROCm.....

AMD scrapped Brook GPUPU compute when they bought ATI.... Many people forget that little fact.....

Brook is now Cuda, same guy runs the program that started it, still works for Nvidia after AMD canned it when he was at Stanford.... Wise choice, wasn't it.....

AMD has terrible market saturation, and they have nothing to compete with Cuda or Optix. Nothing, not even price per compute....

Market saturation of HIP ROCm in desktop programs, is dismal, at best.... Yes, it is in Blender. AMD paid them to put it in there....

Yeah, the AMD gpus are seen to be cheaper, etc. But they are also a very small part of the market share for a reason.

You don't need a 4090 to see crazy fast speeds in Nvidia compute, and AMD doesn't make a desktop card that can even compete with it..

You don't need a 4090 to get preview renders in seconds, Blender live preview on a 4k monitor in cycles, etc, either.

I can do final renders very quickly on a 4070ti. And I get more fps in any game I have than the monitor can display at 4k. Modded Cyberpunk runs fine, at 4k....

A 4070ti is about the same price as a 7900XTX, about the same speed, so why should it be cheaper? Oh wait, the Nvidia card was cheaper when I bought my 4070ti....

If you compare speeds of cards between AMD and Nvidia, the are comparably priced based on compute speed.

But you cant compare a 4090 to and AMD card, simply because AMD doesn't make one that can compete with a 4070ti super, 4080, 4080 super or a 4090 in compute speed.

People compare the 7900XTX to the 4090, asking why the 4090 costs so much more. And don't have a clue how much faster the 4090 actually is than a 7900XTX, not a clue....

If you want an AMD GPU, by all means buy one... Just remember that in compute, many times the Nvidia card is cheaper per compute.....

Stop using gaming benchmarks to justify compute prices, when you want it for compute..

The $800 AMD card and the $800 dollar Nvidia card are about the same speed in compute overall. Until you render in Optix, then the AMD gets destroyed....

Thank you Shvrdavid for the explanations.

I have to say that in 2023, during the summer, I've replaced my old RTX2080Ti by an RTX4070 OC in my then 4 years old computer: slightly less power consumption for more that twice the speed.

I bought my 4070ti last year, and have no regrets for doing so. 

You can buy a used 3060 with 12 gig of vram for a tiny bit more than a RX 5700 XT 8 gig as well..... And the 3060 is faster, massively so when using Optix...

Buy what you want to buy thou. But do your research first... If you primarily game, surf the net, don't need Cuda, Optix, etc. there is nothing wrong with a $130 gpu, from any camp.

Just don't expect and any cheap gpu or any AMD gpu to hold a candle to Nvidia higher end gpu's in compute, that isn't going to happen any time soon simply due to program support..

Who knows, maybe ZLUDA will be a viable option for people at some point, but like anything AMD, it will somehow get changed/scrapped like everything else....

It must really burn AMD up, to know that Cuda thru the IntelOne Api is faster on AMD than anything AMD is on AMD by itself..... Imagine the AMD meetings on that blunder......
