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.

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?

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 for a toy you are allowed to have high standards.

This is the #1 reason why I haven’t upgraded my 2080 Ti. Using my laser printer while my computer is on (even if it’s idle) already makes my UPS freak out. But NVIDIA is claiming that the 5070 is equivalent to the 4090, so maybe they’re expecting you to wait a generation and get the lower card if you care about TDP? Although I suspect that equivalence only applies to gaming; probably for ML you’d still need the highe…

That’s because you have a Brother laser printer which charges its capacitors in the least graceful way possible.

This happens with my Samsung laser printer too, is it not all laser printers?

Fake frames, fake gains

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

Can definitely see more than 60, but it varies how much more you can see. For me it seems like diminishing returns beyond 144Hz.

Though some CRT emulation techniques require more than that to scale realistic 'flickering' effects.

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?).

In theory yes, but it also depends on the workload. RTX 4090 is ranking quite well on the power/performance scale. I'd rather have my card take 400W for 10 minutes to finish the job than take only 200W for 30 minutes.

These are NVidia's financial results last quarter:

- Data Center: Third-quarter revenue was a record $30.8 billion

- Gaming and AI PC: Third-quarter Gaming revenue was $3.3 billion

If the gains are for only 10% of your customers, I would put this closer to the "next to no gains" rather than the "massive gains".

Why not go for AMD? I just got a 7900XTX for 850 euros, it runs ollama or comfyUI via WSl2 quite nicely.

AMD driver quality is crap. I upgraded from GTX 1080 to RX 6950 XT because I found a good deal and I didn't want to support nvidia's scammy bullshit of launching inferior GPUs under the same names. Decided to go with AMD this time, and I had everything: black screens, resolution drops to 1024x768, total freezes, severe lags in some games (BG3) unless I downgrade the driver to a very specific version.

It is an outdated claim.

I have both 4090 (workstation) and 7900XT (to play some games) and I would say that 7900XT was rock solid for me for the last year (I purchased it in Dec 2023).

They are intentionally keeping the VRAM small on these cards to force people to buy their larger, more expensive offerings.

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

forget the post but some dude had a startup piping his 3090 to use via cloudflare tunnels for his ai saas making 5 figures a month off of his 1k gpu that handled the work load, I'd say he was doing it more then right.

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.

If anyone thinks they are having laggier controls or losing latency off of single frames I have a bridge to sell them.

A game running at 60 fps averages around ~16 ms and good human reaction times don’t go much below 200ms.

Users who “notice” individual frames are usually noticing when a single frame is lagging for the length of several frames at the average rate. They aren’t noticing anything within the span of an average frame lifetime

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.

the main point of more fps is lower latency. if you're getting 1000 fps but they are all ai generated from a single real frame per second, your latency will be 500ms and the experience will suck

Primarily concerned about the memory bandwidth for training. Though I think I've been able to max out my M2 when using the MacBook's integrated memory with MLX, so maybe that won't be an issue.

Training is compute bound, not memory bandwidth bound. That is how Cerebras is able to do training with external DRAM that only has 150GB/sec memory bandwidth.

The architectures really aren't comparable. The Cerebras WSE has fairly low DRAM bandwidth, but it has a huge amount of on-die SRAM.
