The FP32 cores got upgraded so all now can do INT32 as well. So the performance problems have to be clock speed related.

NVIDIA official GeForce RTX 50 vs. RTX 40 benchmarks: 15% to 33% performance uplift without DLSS Multi-Frame Generation​

biggest 33% jump only for RTX5090 for $1999

5090 40% faster than a 4090 in blender

very underwhleming increase.... they used GDDR7 and this is what they could muster. poor RT improvement

 

[coercitiv]

But tell me more about what it does to the FPS counter. That's what I want hear about!

Sit down son, we need to have a talk.

Spoiler: The Talk

And don't you try to pay with them fake dollar bills, I can smell 'em a mile away, you hear?

NVIDIA official GeForce RTX 50 vs. RTX 40 benchmarks: 15% to 33% performance uplift without DLSS Multi-Frame Generation​

Wow, that's brutal. Performance uplift essentially equals shader core increase. Consider how tiny those gains would be vs the Super cards. Gains are almost non-existent then.

No wonder there was such extreme focus on fake frames. Fake Frames is all they have... There are essentially 40 Series Super cards with more fake frames.

The 5090 still looks good by comparison, but that 5080 is something else.

 

[Win2012R2]

poor RT improvement

Shocking! I was expecting doubling again to finally make it no brainer option, a least on 5090!

 

[CakeMonster]

Yeah the 5090 is in the range of expected raster FPS for a new gen, which has varied from 40-60%. (Probably) better RT (+10% real perf?) might help sweetening the pill a bit with the fact that its in the lower range and people with the high end cards typically enable RT.

 

[blckgrffn]

The 5090 still looks good by comparison, but that 5080 is something else.

So... is that vs the actual 4080 and not the 4080S?

If so, and yeah I know the 4080S was also a slim uplift that was difficult to measure in some instances, but that's and even smaller uplift over the 4080 variant that most folks seemed to have actually purchased. :/

Also, the 5070 is +20% on the 4070?

So its like a 4070S then? At a slight discount if you can't deal shop? OH BOY.

Lol, so we’re back to the CUDA cores being able to do both FP or INT instructions, which brings us back to Turing/RDNA again. Tensor units don’t appear have more throughput at the same precision, just that it supports lower precision.

I think Moore’s Law is starting to affect Nvidia’s AI performance as well, at least to the point where without going to lower and lower precisions, they won’t be able to constantly claim quadratic increases in AI TOPS. Eventually, they are going to run into a marketing dilemma where even the AI performance gains slow down, so I have to wonder how will they sell their flagship cards without more and more software segmentation.

No wonder there was such extreme focus on fake frames. Fake Frames is all they have... There are essentially 40 Series Super cards with more fake frames.

When considering upgrading from a 4090 to a 5090, one really off-putting feature is the performance uplift is about equal to power consumption uplift. For me, the only game I'd like more performance in is CP2077, 1440p@ultra with RT. Right now I'm getting around 90 FPS pure raster performance and upgrading from a 7800X3D to the 9800X3D didn't change that, so I know it's GPU limited. That said, I'm starting to lean towards keeping my 4090 and wait it out for the next generation. Also, anything below a 5090, I have no interest whatsoever in.

Edit: If I'm willing to accept fake frames, DLSS4 on the 4090 will give more than enough FPS for any game at max settings, so there is absolutely zero value to me in terms of software features currently.

Anyway, get ready for a deluge of videos and articles telling us how important it is to match monitor refresh rates and how unimportant it is to care about lower latency and stuff.

In fact we can start right away

Those uplift numbers are very strange. 5070 Ti has +17% shaders and a 33% bus increase vs 4070 Ti and gets +20%, but the 5070 has +4% shaders and the same bus and also gets +20%?

Super unimpressive though, this will probably be single digit uplift vs their real competition in the ADA Supers.

Looked it up, Turing is 64 FP32+64 INT32... this is 128 FP32+INT32.

 

[Novacius]

Apparently Nvidia mentioned performance numbers without DLSS/AI.

At the Editor's Day, the expected Blackwell performance gains for the 5080, 5070 and 5070 Ti compared to the previous generation without the use of DLSS or AI were also mentioned, which we found to be pleasingly transparent.

The increases mentioned are 15 percent for the RTX 5080, 5070 Ti and 10 percent for the RTX 5070.

Those numbers fit better to the increase in shader count, but oh boy

 

[Saylick]

Oh, you’re right. I remembered wrong.

Pascal and prior had FP/INT, Turing split it up, Ampere added FP to the INT, Ada was the same as Ampere, and now Blackwell adds INT to the remaining FP.

Interesting to see in UE5 games perf

It's coming to all gens...

[Novacius]

The increases mentioned are 15 percent for the RTX 5080, 5070 Ti and 10 percent for the RTX 5070.

These numbers seem to be vs. the original 40 series. That would mean the 5070 is actually slower than the 4070S without AI, the 5070Ti is 5% faster compared to the 4070TiS and the 5080 is 10% faster than the 4080S.

 

[Elfear]

Thought this was an interesting slide for the 5090. I'm assuming DLSS On also includes Reflex 2?

 

[Heartbreaker]

Super unimpressive though, this will probably be single digit uplift vs their real competition in the ADA Supers.

Everything is about equal to shader count increase, except 5070. Maybe they are just pushing 5070 extra hard, because 4070 Super had the biggest gains and if they didn't it would risk underperforming the 4070 Super which would be a tremendously bad look. (runs off to check 4070 super review)

According to HWUB review, 4070 Super is 19% faster than 4070 at 1440p Raster, and According to these benchmarks 5070 is about 20% faster than 4070.

That just makes it equal to 4070 super, so they really had to push the 5070 just to NOT lose. No wonder it got a price cut.
