Performance Slide of RTX 3090 Ampere Leaks, 100% RTX Performance Gain Over Turing

NVIDIA's performance expectations from the upcoming GeForce RTX 3090 "Ampere" flagship graphics card underline a massive RTX performance gain generation-over-generation. Measured at 4K UHD with DLSS enabled on both cards, the RTX 3090 is shown offering a 100% performance gain over the RTX 2080 Ti in "Minecraft RTX," greater than 100% gain in "Control," and close to 80% gain in "Wolfenstein: Young Blood." NVIDIA's GeForce "Ampere" architecture introduces second generation RTX, according to leaked Gainward specs sheets. This could entail not just higher numbers of ray-tracing machinery, but also higher IPC for the RT cores. The specs sheets also refer to third generation tensor cores, which could enhance DLSS performance.

You can do good reflections ala Gears 5. We need better looking hair and trees and textures and so much more than lighting imo. I'd like a 32GB VRAM card instead of an RT card. There is so much wasted silicon with the latest cards.
"Good reflections" doesn't contradict what I said. As I said in the very post you quoted: screen space reflections are great, until you're looking at something reflective that ought to be reflecting off-screen objects or scenery. And that is the type of thing that can have a dramatic effect on immersion when you notice it, as it makes the gameworld feel all that much more real and less artificial.

Besides, scaling rasterization much higher would put massive pressure on the memory subsystem, which would be problematic in and of itself. There's plenty of improvements to rasterization to be had in these GPUs already, asking for more is just asking for a memory bottleneck.

And that's what RT will eventually enable: when you get reflections, ambient occlusion for free, you'll have more HP at your disposal to throw at geometry. But not just yet when games are still mostly about rasterizing with a little RT on top.

I'm not even sure why we're discussing this, it's not like RT is a gimmick Nvidia pulled out of their hat yesterday. RT has been the choice for professional rendering for decades. Because it produces superior results.

Free you mean allocating silicone space and resources to integrating it in place of other hardware. Look I installed a supercharger on the engine and am charging you more for it's "free performance" enjoy comrade.

it produces inferior results, we are playing in real time, not offline... ugh... anyways the RT believers are not worth arguing with

No, it doesn't. Read up on it, there's many free papers on the subject.

Based on TPU review of Control. RTX on will cut 2080Ti performance to half in 1080p

www.techpowerup.com/review/control-benchmark-test-performance-nvidia-rtx/4.html

Without DLSS, 2080Ti gets about 100FPS avg at 1080p, 50fps avg at RTX 1080P.

So now RTX3090 gets about 100 fps on RTX 1080p (>2X from this chart)

That means RTX3090 needs at least 200FPS on regulation 1080p, that is without RTX. Of course this is assuming no RT efficiency improvement. Let's assume there is some major RT effieceny improvement so instead of 0.5X performance penalty we have 0.7X performance penalty. Then RTX3090 would be running 133FPS to 150FPS without RTX. So a 30% to 50% performance uplift in non-RTX games. Also we have 5248 versus 4352 CUDA core. So CUDA core increase by itself should give at least 20% performance in nonRTX

That is just some quick napkin math. I am more leaning towards 30%~35% performance increase. But there is a good chance that I am wrong
Sorry, you lost me at 1080p, damn that eternal resolution, it'll outlive NTSC.
