AMD Perfects Ray Tracing?! RDNA 4 OVERHAULS RT Tech

AMD Perfects Ray Tracing?! RDNA 4 OVERHAULS RT Tech

Yet more leaks for AMD's RDNA 4, this time on the expected ray tracing improvements for the next gen Radeon GPUs. Join us as we examine the latest RDNA 4 leaks, which if accurate, could mean that RDNA 4 has NVIDIA CLASS RT. One area RDNA 3 disappointed was it's ray tracing performance in comparison to RTX 40, so with AMD allegedly PERFECTING their ray tracing, we could see RDNA 4 match the RT performance of Nvidia GPUs in the same tier.

Of course, we already know that RDNA 4 will not have a high end / flagship graphics card, but that doesn't mean that the Radeon RX 8000 can't have competitive ray tracing at it's price and performance tiers. Safe to say, it's going to be VERY interesting to see AMD target the mid / budget range but challenge Nvidia on the RT field.

I'm still not seeing the juice for the amount of squeeze with RT. When I've used it, it didn't look good enough to kill my fps for it.

[shmookins]

Fascinating. Thanks for the update.

Everybody talking about ray tracing, but nobody talks about physics simulation.

After the age of polygon count, I thought physics simulation would be next.
I remember those jaw dropping cloth, water, and smoke real-time simulation demos on Nvidia cards from 15 years ago and I still don't see that level in games today.

I wonder if physics, or something else, will be the focus after the ray tracing era.

[nipa]

RT might get important one day when it's implemented in most games and also won't cripple the frame rate anymore.

[Logical]

I want AMD to succeed but they shoot themselves in the foot everytime.

[evilsatorii]

I still prefer playing at 240 FPS then 60 FPS ( or even lover) with RT

[ElysaraCh]

based on whitepapers about RDNA2's architecture - which likely carried over to RDNA3 - their RT implementation could handle 4 rays-in-flight OR 1 ray intersection per clock, which is why "heavy" RT implementations cripple Radeon RT performance so badly. It's likely the RDNA4 implementation doesn't have that weakness.

[NecroViolator]

Raytracing nothing new. Been around since 1980's in the Amiga !.

[morpheus_]

Im waiting for RDNA5 unless my 6750XT shits the bed or becomes so slow i cant use it anymore

[Etheoma]

Probably not because last time they did a proper techical breakdown the normies were like "WTF is this. We wanted the shiny, not the nuts and bolt." not realizing it was a game developer conference so they were going to get technical.

[xephyrxero]

This is great news if true. AMD has been lagging a generation or two behind Nvidia in the ray tracing department and needs a dramatic overhaul if they're ever going to catch up. In 5 years, RT will be a standard feature in almost every major title, and there will be many more fully path traced games out by then too. And when it comes to RT, Intel seems like they are ahead of AMD too currently. So AMD could find themselves in the #3 spot if something doesn't change soon

"I will be quite hyped if RDNA 4 does live up to the rumors for a midrange GPU..." As would everyone including me. But has AMD ever managed to launch a GPU that's lived up to the hype? I'll cross my fingers, but I'm not holding my breath.

[MrBlackdragon]

So I guess I will be the odd one out here that wants maxed graphics and RT and be happy with 60ish fps. I dont know why no one can see the difference with maxed out settings and rt on but I can and enjoy the hell out of it. I ran Control on my old 1080ti over clocked to hell and back with rt on!

[technite]

Hopefully just like Nividia in RDNA5 they will use Dedicated Ray Accelerator outside the CUs

[CHT]

Yeah i would like them to focus on improving RT and TDP on their GPUs next gen... Even if their high end GPU only matches the 4090/5080 more or less at a much better price point. My 1080ti is reaching its limits, i might stretch it another generation, which means RX 9000 or RTX 6000 might be the lineups for me, all depends on how things are by then. I have little hopes on nvidia doing good...

[morpheus_]

If the 8800XT is 5-15% faster than the 7900XT in raster and 10-30% faster in RT while using 240-250W at $449-499 that would be fucking AWESOME.

[aberkae]

The best return on investment in terms of performance hit for visual quality improvement imo is rt global illuminations especially with hdr. The screen pops vs rasterization ambient occlusio

[drkevorkian]

I'll believe it when I see it. The same thing happened with FSR2. People claimed it caught up to DLSS, but over time it became obvious that they really hadn't and even XESS was better.

[pieterboots]

I expect AI models to come up with new algorithms that would significantly speed up the process of rendering frames.

[omnivos]

Amd pricing will be in-line with Nvidia. 7900xtx 250 fps in 54 hr average Helldivers 2 everything turned on and maxed out except for motion blur. 3400x1440.

[gametime]

i would argue that answer to DLSS would be more important than answer to the better RT on NV cards.
everyone use up scaling today and it can rally extent the life of a card and FSR is just not good enough...

and lets not forget that RTX 50 probably will improve RT ofer RTX 40.
so lets say they managed to be as good as 4070TI RT, they might still lose to a 5060 or 5070 (non ti) RT
