NVIDIA RTX 50 SERIES - Technical/General Discussion

TNA said:
Suddenly the script has flipped and it is about raster power. Was all about RT not long ago :cry:

Nvidia made very little changes to RT this gen - as I said in the past, proper actually fast RT for full PT in games requires very different hardware than current RT cores can provide with current slow vRAM. Many orders of magnitude faster vRAM is needed (faster than L1 cache can provide currently). Nvidia is nowhere near there and thir focus is AI not RT anymore. Now, to drive fancy looking UE5 games with hardware Lumen, GPU still requires to have very fast raster too - these games are all hybrid, still. Hence, raster performance still matter a lot and will for many years to come, even in RT based games (and so does CPU performance as a lot of RT computation is still done on the CPU).

Maybe if all you play is a handful of select AAA games. Otherwise, it is as relevant as ever.

Not even that, if you speed up just RT you will fall behind processing all the geometry and bunch of effects running on cuda cores and will hardly see any performance increase even in such games. Mostly 100% PT games you could see some increase but not that much there either - something on the raster side will be a bottleneck in the end. People seem to be forgetting raster = cuda cores = all kinds of universal computation. You can't have games with just light and nothing else in them. :D All "raster" is these days are just math computations on cuda cores. RT uses that too plus additional acceleration on RT cores plus CPU.

Raster is still important the 7800XT is underpowered in RT but absolutely demolishes games at 1440p and it's been AMD top seller card. Nvidia mid range doesn't offer enough Vram to enjoy RT, and frankly releasing cards with 12GB of Vram in 2025 insulting because 12GB of Vram should be the norm for the entry level not the mid range.

If I'm paying £500+ for a card then 16GB should be the norm. Hopefully Nvidia don't release a 5060 with 8GB and price it at £300+

Sure. I agree raster won't be going anywhere anytime soon. But that is not what 4090 owners in particular were saying on this forum. They wanted more RT performance.

Now if the 5090 provides at least 40% uplift on RT and still gets slated by these user we will know that we have reached a price point where even these users can't justify the cost.

Won't be the case of, the hell with it just buy it, smash it or what have you.

I get the feeling the 5090 won't sell half as many units as the 4090 did by the time the 6090 is out.

Shame the 5080 does not have better specs. Had it been a little more beefy to at least match the 4090 in every way (except for say vram) it would have done better. But if it ends up weaker in every department except for having MFG it won't be as popular as it would have been.

Not long left now T- 1:54 :D
 
You can try the new DLSS 4.0 transformer model right now - Cyberpunk just got patched with it. Works for 4000 and 5000 series.

Patch 2.21

www.cyberpunk.net www.cyberpunk.net

Added support for DLSS 4 with Multi Frame Generation for GeForce RTX 50 Series graphics cards, which boosts FPS by using AI to generate up to three times per traditionally rendered frame – enabled with GeForce RTX 50 Series on January 30th. DLSS 4 also introduces faster single Frame Generation with reduced memory usage for RTX 50 and 40 Series. Additionally, you can now choose between the CNN model or the new Transformer model for DLSS Ray Reconstruction, DLSS Super Resolution, and DLAA on all GeForce RTX graphics cards today. The new Transformer model enhances stability, lighting, and detail in motion.
