It's pretty underwhelming. Might be tough for it to stick at $1199, even factoring nVidia.

You keep repeating the same thing which is at odds with what I've read on the subject. Fixed function means only doing one thing. Nvidia's RT cores are fixed function because they only do ray tracing calculations. AMD's RT cores are not fixed function because they can process other things when not actively engaged in a ray tracing workload. That's actually a very efficient method of implementing RT (especially for the consoles), but it comes at the cost of raw performance.

From what I've read, Nvidia's RT cores remain in idle when not doing ray tracing while AMD's do not.

I'm willing to admit that I'm not a graphics engineer so my understanding of this subject is very limited so I could very well be wrong.

I keep repeating it because that's what the RT cores are in both AMD and NVIDIA, fixed function units. They can only process specific arithmetic calculations (BVHs etc), they are not all purpose ALUs like the Shader units that can do a lot of different calculations. There is nowhere in what you linked that says the AMDs RT cores can do more things than RT. What you misunderstand is the difference of the architecture and how the RT cores are functioning within the CU and SM, but that doesnt mean the AMD RT cores are not fixed function units and can do more things. If that was true, they would not name them Ray Accelerators and instead would put the all purpose Shaders to do the math.

It's going to vary by game. Games with heavy RT loads are going to show a massive gap between RDNA3 and Ada. Hardwaretimes actually wrote an analysis on the publicly released benchmarks of RDNA3:

AMD RX 7900 XTX Scores Just 21 FPS in Cyberpunk 2077 with Ray Tracing, NVIDIA RTX 4090 Over 2x Faster | Hardware Times

If you take the AMD slide and Techpowerups RTX4080 FE review you can see that RTX4080 will only be 38% faster in the heaviest RT game today at 4K, Cyberpunk 2077. 21fps vs 29fps

The difference in the same game between RX6950XT vs RTX3090Ti witch have almost the same die size (NAVI21 520mm2 vs GA102 628mm2) is almost double from 13fps to 24fps.
So with RDNA3, AMD has actually closed the gap in RT architecturally and the only difference now is the die size of each SKUs.

Have you tried DLAA? Supposedly that one is the best for image quality.


I've only tried DLSS in one game so far and that was A Plague's Tale Requiem. The implementation was very good and I couldn't detect any image quality problems. This was with DLSS set to quality.

I tried DLAA in one game and wasn’t a fan. Made Fallout 4 blurry. F4 does require TAA due to severe shimmering on foliage. The game engine doesn’t support MSAA. FidelityFX + NV game filter do make TAA look quite good though.

But there is one new exclusive Nvidia feature that I love called SSRTGI (screen space ray traced global illumination).
Nvidia isn’t advertising this feature for some reason. They don’t even say when a game becomes supported. Enabling this on older games like Fallout 4 provide an incredible
visual boost.

NVIDIA DLDSR On-Off Interactive Comparison

It really does look this good! I don’t use DLDSR though. Enabling SSRTGI increases power consumption considerably though.

Some games I play like Risk of Rain 2 and Kerbal Space Program didn’t have the option to do SSRTGI until a recent driver release. It doesn’t work well in KSP yet, but I had no SSRTGI option for that game until very recently.

If I was NV I would be showing off this feature for the 4080 and 4090 release since SSRTGI can become quite performance intensive if doing higher quality; and AMD has no answer to SSRTGI.

No Surprise, but it looks like 4080 is selling poorly, while the 4090 keeps selling out. This is pretty much expected because once you are over a $1000 for a GPU you probably aren't looking at a value buyer, and for them a couple hundred more to have the "best" GPU probably makes more sense than saving 20% and settling for second best.

While I am a value buyer (never paid more than $300 for a GPU), if I suddenly found myself with a bunch of excess cash to the point that I was thinking of $1000+ GPU, I'd just go straight to the top.

NVIDIA has sold 160K GeForce RTX 40 graphics cards already, but stores are still full of RTX 4080s - VideoCardz.com

NVIDIA RTX 40 sales reports The RTX 4080 is not selling particularly well on the first week. First estimates on RTX 40 series sales have been shared by a few sources, but even despite impressive numbers, retailers are worried it may not as popular a choice as RTX 4090. According to Wccftech and...

So do the AMD RT cores idle when not being used like the Nvidia RT cores?

If you take the AMD slide and Techpowerups RTX4080 FE review you can see that RTX4080 will only be 38% faster in the heaviest RT game today at 4K, Cyberpunk 2077. 21fps vs 29fps

So it's about the same performance as an RTX 3080 Ti. Ada is a big jump over Ampere because of the new process node.

yes, when you dont do any RT workload those units are idling.

Treated members lovingly? I think you guys are a tad bit sensitive. I have zero obligation to coddle your purchasing decisions and stoke your company loyalties.

What strokes your company loyalties? Never mind we know.

 

[Kaluan]

So it's about the same performance as an RTX 3080 Ti.

By the same logic. Ryzen 7600X is like 25% faster than Raptor Lake i9 in gaming. Cause Horizon: Zero Dawn.

Ooh, bet you don't like THAT type of cherry-picking. Not exactly flattering to your brand sensibilities now, is it... 😂

 

[Carfax83]

What strokes your company loyalties? Never mind we know.

I'm in tribe "whoever has the fastest hardware.".

I want the best, not the most budget effective. And it just burns you to the core that there are lots of people like me that will buy the fastest hardware regardless of price because we value the experience above all else.

Don't blame us because AMD is a poor competitor and hasn't had a worthy high end product in God knows how long, and don't try to coax or guilt trip us into giving loyalty to a company because they are the underdog and their business practices are slightly less offensive than the competition.

We don't care about any of that. Now do yourself a favor and block me. Your endless whining and complaining about Nvidia and Intel while worshipping AMD is quite boring to be honest.

 

[Carfax83]

Horizon Zero Dawn isn't remotely comparable to CBP 2077. The former is an average PS4 port and the latter is a PC game first and foremost with cutting edge Ray Tracing.

The fact that you would even put the two in the same sentence goes to show how ass backwards your thinking is.

Ooh, bet you don't like THAT type of cherry-picking. Not exactly flattering to your brand sensibilities now, is it... 😂

You're the brand loyalist, not me. I buy the fastest hardware regardless of brand, you just buy whatever has an AMD sticker on it.

And like I told your buddy, go ahead and block me. I wouldn't miss much since 98% of your posts are pro AMD and anti Intel and Nvidia. Seeing the two of you constantly whining about other peoples' hardware purchases is nauseating.

I've never seen an Nvidia or Intel user actively complain about what other people buy, only AMD users.

There you go, justifying your purchases to others again. It just burns you up when others don't share your enthusiasm about your spending doesn't it?

 

[moonbogg]

You guys can't actually be arguing with each other about this stuff. I refuse to believe that's possible. Explain to me, in detail, how it's possible to care enough to actually FIGHT about a video card. I'm waiting. Please. Go ahead. Hit me with it. Time for the truth bomb.

 

[Carfax83]

People for whom performance is the first and last consideration. People like that have no brand loyalty. I honestly wouldn't consider myself as being a brand loyalist. I have owned AMD hardware many times in the past, even had a couple of crossfire rigs back in the day. I only care about maximum gaming performance at the highest quality settings, and Intel + Nvidia have been the go to for those that want that combination for a long time now. Zen 3 took the CPU performance crown back from Intel for a while and I almost bought a Zen 3 based rig. The reason I didn't is because I didn't think the performance increase was large enough with Zen 3 to pull the trigger (coming from Broadwell-E). Same reason why I never bought any of the Skylake or Skylake derivatives as well.

 

[Carfax83]

I can see this must be your first time on a PC hardware enthusiast forum, because it's the norm for people to justify their purchases and builds in different ways; usually through overt or stealth bragging. Go and look in the Zen 4 or Raptor Lake builds thread and you'll see nothing but page after page of endless justification. Usual business, nothing to see here.

What's different about you guys, is that you became unhinged after my strong criticism of AMD's graphics performance and quality. I hope AMD gives you guys some type of compensation for being such loyal foot soldiers

And this is the post that kick started this nonsense.

A strong critique of AMD's graphics performance and quality compared to Nvidia's caused them to become unhinged and self immolate. I can only imagine how bent out of shape they get about something like politics

Lol. I've been a member here longer than you have, but ok. 😂

And to top it off I have an Intel CPU and an Nvidia GPU, I just don't let it define me. But you seem to know everything about me, right.

The difference is that those threads are specifically for that purpose, but you don't stop there. You continue your agenda in all other parts of the forum.

Let's not pretend that a perceived NV guy is the only one to continue an agenda in all other parts of the forum. Plenty of fanatics/acolytes here for AMD/Intel/NV.

Well you seemed genuinely surprised that people actively justify their purchasing decisions on a PC hardware enthusiast forum. I mean, between the build threads, competitive benchmarks and the sigs, how could you possibly not know that?

The difference is that those threads are specifically for that purpose, but you don't stop there. You continue your agenda in all other parts of the forum.

And what agenda do I have if I may ask? I criticize AMD harshly because they are the reason why Nvidia can get away with charging exorbitant fees for their products. Because AMD is unable or unwilling to compete on the high end. It's the same reason why Intel was able to get away with a lot of things in the pre-Zen era.

Healthy competition is vital to any industry and while I give credit to AMD's CPU engineers with the Zen lineup which has been very robust and even superior to Intel's offerings at times, their graphics division has been an unmitigated disaster that have been playing "catch up" to Nvidia for seemingly forever.

You would be surprised. If Freud were still alive, he would dump all those parent related inquiries for a far more daunting approach: Tell me your.... GPU history!

they are the reason why Nvidia can get away with charging exorbitant fees for their products.

Like I just said, that's some freudian stuff right there.

 

[linkgoron]

I just said, that's some freudian stuff right there.

Look at what AMD made them do! Buy Nvidia at outrageous prices!

 

[Tup3x]

If you don't care about what things cost and just want the fastest thing in the world then that narrows it down to single card...

While I could easily buy RTX 4090, my biggest issue with it (price aside) is the power consumption. Personally I think that 250 W max should be plenty and ideally even lower. RTX 4080 is almost acceptable but it's not optimal (same thing for 7900 XT/XTX). It also bothers me quite a bit that NVIDIA didn't include DP2.0/2.1 ports when even Intel Arc cards have it.

But since I do care about value, I just can't justify the price especially for RTX 4080. It's insane and nobody should be buying. It gives wrong signal.

 

[Carfax83]

Nah, they'll just keep pretending. It's OK, because anyone who reads the entire thread in an objective manner will see exactly what started this argument........and it wasn't purchase history.
