As a lifelong nvidia consumer, I think it's a safe bet to ride out the first wave of 5xxx series GPUs and wait for the inevitable 5080/5070 (GT/Ti/Super/whatever) that should release a few months after with similar specs and better performance based on whatever the complaints surrounding the initial GPUs lacked. I would expect something like the 5080 super will have something like 20/24Gb of VRAM. 16Gb just seems wro…

A few months? Didn't the 4080 Super release at least a few years after the 4080?

I still have a 3080 and game at 4K/120Hz. Most AAA games that I try can pull 60-90Hz at ~4K if DLSS is available.

Most numbers people are touting are from "Ultra everything benchmarks", lowering the settings + DLLS makes 4k perfectly playable.

I've seen analysis showing that DLSS might actually yield a higher quality image than barebones for the same graphics settings owing to the additional data provided by motion vectors. This plus the 2x speedup makes it a no brainer in my book.

I exceed 16GB in Chrome.

That says more about Chrome than anything else. I use Firefox and have an 8Gb card and only encounter problems when I have more than about 125 windows with about 10-20 tabs each. Yes, I am a tab hoarder. And yes, I am going to buy a 16Gb card soon. :P

1200 tabs isn't that many

In the server space there is gen 5 cabling but not gen 5 risers.

> gen 5 cabling Do you mean OCuLink? Honestly, I never thought about how 1U+ rackmount servers handle PCIe Gen5 wiring/timing issues between NVMe drives (front), GPUs/NICs (rear), and CPUs (middle).

OCuLink has been superseded by MCIO. I was speaking of the custom gen 5 cabled nvme backplane most servers have.

The fps gains are directly because of the AI compute cores, I’d say that’s a net gain but not a the traditional sense preAI.

Kind of a half gain: smoothness improved, latency same or slightly worse. By the way, I thought these AI things served to increase resolution, not frame rate. Why doesn't it work that way?

It's both. And it's going to continue until games are 100% and AI fever dream.

Somewhat related, any recommendations for 'pc builders' where you can configure a PC with the hardware you want, but have it assembled and shipped to you instead of having to build it yourself? With shipping to Canada ideally. I'm planning to upgrade (prob to a mid-end) as my 5 year old computer is starting to show it's age, and with the new GPUs releasing this might be a good time.

I don't know of any such service, but I'm curious what the value is for you? IMO picking the parts is a lot harder than putting them together.

Typically you get warranty on the whole thing through a single merchant, so if anything goes wrong you don't have to deal with the individual parts manufacturers.

No gamers need such high VRAM, if you're buying Gaming cards for ML work you're doing it wrong.

MS Flight Simulator 2024 can consume...who knows how much. I know my 10 GB 3080 ran out of VRAM playing it on Ultra, and i was getting as low as 2 fps because I'm bottlenecked by the PCI-Express bus as it has to constantly page the entire working set of textures and models in and out. I'm getting a 5090 for that, plus I want to play around with 7B parameter LLMs and don't want to quantize below 8 bits if I can help i…

I've regularly exceeded 24 GiB of VRAM in Microsoft Flight Simulator 2024. Imagine a huge airport environment with high levels of detail, plus AI aircraft in the ground and sky. Then, on top of that, terrain and textures of the surrounding environment.

And that's at 1440p, not even 4K. The resulting stutters are... not pretty.

Does any game need 32gb VRAM. Did they even use the full 24Gb of the 4090s?

It seems obvious to me that even NVIDIA knows that 5090s and 4090s are used more for AI Workloads than gaming. In my company, every PC has 2 4090s, and 48GB is not enough. 64GB is much better, though I would have preferred if NVIDIA went all in and gave us a 48GB GPU, so that we could have 96GB workstations at this price point without having to spend 6k on an A6000.

Overall I think 5090 is a good addition to the quick experimentation for deep learning market, where all serious training and inference will occur on cloud GPU clusters, but we can still do some experimentation on local compute with the 5090.

Similar CUDA core counts for most SKUs compared to last gen (except in the 5090 vs. 4090 comparison). Similar clock speeds compared to the 40-series. The 5090 just has way more CUDA cores and uses proportionally more power compared to the 4090, when going by CUDA core comparisons and clock speed alone. All of the "massive gains" were comparing DLSS and other optimization strategies to standard hardware rendering. Som…

I started thinking today, when Nvidia seemingly keeps just magically increasing performance every two years, that they eventually have to "intel" themselves, where they haven't made any real architectural improvements in ~10 years and just suddenly power and thermals don't scale anymore and you have six generations of turds that all perform essentially the same, right?

They already predicted this hence DLSS and other AI magic.

Sounds to me like they made "massive gains". In the end, what matters to gamers is 1. Do my games look good? 2. Do my games run well? If I can go from 45 FPS to 120 FPS and the quality is still there, I don't care if it's because of f…

Rasterizing results in better graphics quality than DLSS if compute is not a limiting factor. They are trying to do an apples to oranges comparison by comparing the FPS of standard rendering to upscaled images. I use DLSS type tech, but you lose a lot of fine details with it. Far away text looks blurry, textures aren’t as rich, and lines between individual models lose their sharpness. Also, if you’re spending $2000 f…

DLSS is becoming the standard rendering.
