> modern games + modern cards can't even do 4k at high fps What "modern games" and "modern cards" are you specifically talking about here? There are plenty of AAA games released last years that you can do 4K at 60fps with a RTX 3090 for example.

> There are plenty of AAA games released last years that you can do 4K at 60fps with a RTX 3090 for example. Not when you turn on ray tracing. Also 60fps is pretty low, certainly isn't "high fps" anyway

Personally I've yet to see a ray tracing implementation that I would sacrifice 10% of my framerate for, let alone 30%+. Most of the time, to my tastes, it doesn't even look better, it just looks different.

The increasing TDP trend is going crazy for the top-tier consumer cards: 3090 - 350W 3090 Ti - 450W 4090 - 450W 5090 - 575W 3x3090 (1050W) is less than 2x5090 (1150W), plus you get 72GB of VRAM instead of 64GB, if you can find a motherboard that supports 3 massive cards or good enough risers (apparently near impossible?).

Instead of risers just use pcie ender cords and you can get 4x 3090's working with a creator motherboard (google one that you know can handle 4). You could also use a mining case to do the same.

But, the advantage is that you can load a much more complex model easily (24GB vs 32GB is much easier since 24GB is just barely around 70B parameters).

This is maybe a dumb question, but why is it so hard to buy Nvidia GPUs? I can understand lack of supply, but why can't I go on nvidia.com and buy something the same way I go on apple.com and buy hardware? I'm looking for GPUs and navigating all these different resellers with wildly different prices and confusing names (on top of the already confusing set of available cards).

It depends on the timing. I lucked out about a year ago on the 4080; I happened to be shopping in what turned out to be the ~1 month long window where you could just go to the nvidia site, and order one.

GPUs are in demand. So scalpers want to make a buck on that. All there is to it. Whenever demand surpasses supply, someone will try to make money off that difference. Unfortunately for consumers, that means scalpers use bots to clean out retail stores, and then flip them to consumers.

Without thinking about it too deeply I'm wondering if GPU demand is that much higher than let's say iPhone demand. I don't think I've ever heard of iPhones being scarce and rare and out of stock.

> will be two times faster [...] thanks to DLSS 4 Translation: No significant actual upgrade. Sounds like we're continuing the trend of newer generations being beaten on fps/$ by the previous generations while hardly pushing the envelope at the top end. A 3090 is $1000 right now.

It looks like the new cards are NO FASTER than the old cards. So they are hyping the fake frames, fake pixels, fake AI rendering. Anything fake = good, anything real = bad.

Jensen thinks that "Moore's Law is Dead" and it's just time to rest and vest with regards to GPUs. This is the same attitude that Intel adopted 2013-2024.

Why is that a problem though? Newer and more GPU intensive games get to benefit from DLSS 4 and older games already run fine. What games without DLSS support could have done with a boost? I've heard this twice today so curious why it's being mentioned so often.

Has DLSS now

Yeah, that's bullshit. I have a 3090 and I never want to use it at max power when gaming, because it becomes a loud space heater. I don't know what to do with 575W of heat.

Sounds like you might be more the target for the $3k 128GB DIGITS machine.

Weirdly they're advertising "1 petaflop of AI performance at FP4 precision" [1] when they're advertising the 5090 [2] as having 3352 "AI TOPS" (presumably equivalent to "3 petaflops at FP4 precision"). The closest graphics card they're selling is the 5070 with a GPU performing at 988 "AI TOPS" [2]....

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.

Something tells me Nvidia made next to no gains for this generation.

Double the bandwidth, double the ram, double the pins, and double the power isn't cheap. I wouldn't be surprised if the profit on the 4090 was less than the 4080, especially since any R&D costs will be spread over significantly less units.

There have been numerous reports over the years that the 4090 actually outsold the 4080.

The 4080 was designed as a strawman card expressly to drive sales towards the 4090. So this is by design.
