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?).

Nvidia wants you to buy their datacenter or professional cards for AI. Those often come with better perf/W targets, more VRAM, and better form factors allowing for a higher compute density. For consumers, they do not care. PCIe Gen 4 dictates a tighter tolerance on signalling to achieve a faster bus speed, and it took quite a good amount of time for good quality Gen 4 risers to come to market. I have zero doubt in my…

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

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.

I also like DLSS, but the OP is correct that it is a problem. Specifically it's a problem with understanding what are these cards capable of. Theoretically we would like to see separately performance with no upscaling at all, then separately with different levels of upscaling. Then we would be able to see easier what is the real performance boost of the hardware, and of the upscaler separately. It's like BMW comparin…

How situation actually looks like will be revealed soon via independent tests. I'm betting its bit of both, no way they can't progress in 2 years raw performance at all, other segments still manage to achieve this. Even 10%, combined with say 25% boost with DLSS, nets nice FPS increase. I wish it could be more but we don't have a choice right now.

Does normal gamers actually notice any difference on some normal 4k low latency monitors/tvs? I mean any form of extra lag, screen tearing etc.

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…

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…

Because if two frames are fake and only one frame is based off of real movements, then you've actually lost a fair bit of latency and will have noticably laggier controls.

Making better looking individual frames and benchmarks for worse gameplay experiences is an old tradition for these GPU makers.

> 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 are you upset how a frame is generated? We're not talking about free range versus factory farming. Here, a frame is a frame and if your eye can't tell the difference then it's as good as any other.

If you have 128gb ram, try running MoE models, they're a far better fit for Apple's hardware because they trade memory for inference performance. using something like Wizard2 8x22b requires a huge amount of memory to host the 176b model, but only one 22b slice has to be active at a time so you get the token speed of a 22b model.

I guess they're tired of people buying macs for AI.

Fake frames, fake gains

The human eye can't see more than 60 fps anyway

Are crypto use cases still there? I thought that went away after eth switched their proof model.

Bitcoin is still proof of work.

Yeah but BTC is not profitable on GPU I thought (needs ASIC farms)

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

Games already exceed 16 GBs at 4k from years.

I exceed 16GB in Chrome.

Yeah. I've been looking at changing out my home lab GPU but I want low power and high ram. NVIDIA hasn't been catering to that at all. The new AMD APUs, if they can get their software stack to work right, would be perfect. 55w TDP and access to nearly 128GB, admittedly at 1/5 the mem bandwidth (which likely means 1/5 the real performance for tasks I am looking at but at 55w and being able to load 128g....)

Latency and visual artifacts.
