* MegaGeometry (APIs to allow Nanite-like systems for raytracing) - super awesome, I'm super super excited to add this to my existing Nanite-like system, finally allows RT lighting with high density geometry

* Neural texture stuff - also super exciting, big advancement in rendering, I see this being used a lot (and helps to make up for the meh vram blackwell has)

* Neural material stuff - might be neat, Unreal strata materials will like this, but going to be a while until it gets a good amount of adoption

* Neural shader stuff in general - who knows, we'll see how it pans out

* DLSS upscaling/denoising improvements (all GPUs) - Great! More stable upscaling and denoising is very much welcome

* DLSS framegen and reflex improvements - bleh, ok I guess, reflex especially is going to be very niche

* Hardware itself - lower end a lot cheaper than I expected! Memory bandwidth and VRAM is meh, but the perf itself seems good, newer cores, better SER, good stuff for the most part!

Note that the material/texture/BVH/denoising stuff is all research papers nvidia and others have put out over the last few years, just finally getting production-ized. Neural textures and nanite-like RT is stuff I've been hyped for the past ~2 years.

I'm very tempted to upgrade my 3080 (that I bought used for $600 ~2 years ago) to a 5070 ti.

Yes, but Nvidia thinks enough of them get pushed up to the 5090 to make the gap worthwhile. Only way to fix this is for AMD to decide it likes money. I'm not holding my breath.

Don't necessarily count Intel out.

Intel is halting its construction of new factories and mulling over whether to break up the company...

There was some solid commentary on the Ps5Pro tech talk stating core rendering is so well optimized much of the gains in the future will come from hardware process technology improvements not from radical architecture changes. It seems clear the future of rendering is likely to be a world where the gains come from things like dlss and less and free lunch savings due to easy optimizations.

Nanite style rendering still seems fairly green. That could take off and they decide to re-implement the software rasterization in hardware.

Raster is believe it or not, not quite the bottleneck. Raster speed definitely _matters_, but it's pretty fast even in software, and the bigger bottleneck is just overall complexity. Nanite is a big pipeline with a lot of different passes, which means lots of dispatches and memory accesses. Same with material shading/resolve after the visbuffer is rendered.

EDIT: The _other_ huge issue with Nanite is overdraw with thin/aggregate geo that 2pass occlusion culling fails to handle well. That's why trees and such perform poorly in Nanite (compared to how good Nanite is for solid opaque geo). There's exciting recent research in this area though! https://mangosister.github.io/scene_agn_site.

Even though they are all marketed as gaming cards, Nvidia is now very clearly differentiating between 5070/5070 Ti/5080 for mid-high end gaming and 5090 for consumer/entry-level AI. The gap between xx80 and xx90 is going to be too wide for regular gamers to cross this generation.

The 4090 already seemed positioned as a card for consumer AI enthusiast workloads. But this $1000 price gap between the 5080 and 5090 seems to finally cement that. Though we're probably still going to see tons of tech YouTubers making videos specifically about how the 5090 isn't a good value for gaming as if it even matters. The people who want to spend $2000 on a GPU for gaming don't care about the value and everyone else already could see it wasn't worth it.

I wouldn't count Intel out in the long term, but it'll take quite a few generations for them to catch up and who knows what the market will be like by then

For gaming I'm also looking forward to the improved AI workload sharing mentioned, where, IIUC, AI and graphics workloads could operate at the same time.

I'm hoping generative AI models can be used to generate more immersive NPCs.

32GB of GDDR7 at 1.8TB/sec for $2000, best of luck to the gamers trying to buy one of those while AI people are buying them by the truckload. Presumably the pro hardware based on the same silicon will have 64GB, they usually double whatever the gaming cards have.

At what point do we stop calling them graphics cards?

It's a good question. I'll note that, even in the GPGPU days (eg BrookGPU), they were architecturally designed for graphics applications (eg shaders). The graphics hardware was being re-purposed to do something else. It was quite a stretch to do the other things compared to massively-parallel, general-purpose designs. They started adding more functionality to them, like physics. Now, tensors.

While they've come a long way, I'd imagine they're still highly specialized compared to general-purpose hardware and maybe still graphics-oriented in many ways. One could test this by comparing them to SGI-style NUMA machines, Tilera's tile-based systems, or Adapteva's 1024-core design. Maybe Ambric given it aimed for generality but Am2045's were DSP-style. They might still be GPU's if they still looked more like GPU's side by side with such architectures.

Let's see the new version of frame generation. I enabled DLSS frame generation on Diablo 4 using my 4060 and I was very disappointed with the results. Graphical glitches and partial flickering made the game a lot less enjoyable than good old 60fps with vsync.

The new DLSS 4 framegen really needs to be much better than what's there in DLSS 3. Otherwise the 5070 = 4090 comparison won't just be very misleading but flatly a lie.

Nvidia is also clearly differentiating the 5090 as the gaming card for people who want the best and an extra thousand dollars is a rounding error. They could have sold it for $1500 and still made big coin, but no doubt the extra $500 is pure wealth tax.

It probably serves to make the 4070 look reasonably priced, even though it isn't.
