Yeah, do like me, I lower settings from "ultra hardcore" to "high" and keep living fine on a 3060 at 1440p for another few gens. I'm not buying GPUs that expensive nor energy consuming, no chance. In any case I think Maxwell/Pascal efficiency won't be seen anymore, with those RT cores you get more energy draw, can't get around that.

I've actually reversed my GPU buying logic from the old days. I used to buy the most powerful bleeding edge GPU I could afford. Now I buy the minimum viable one for the games I play, and only bother to upgrade if a new game requires a higher minimum viable GPU spec. Also I generally favor gameplay over graphics, which makes this strategy viable.

Yeah, that's another fact.

I upgrade GPUs then keep launching League of Legends and other games that really don't need much power :)

I'm generally a 1080p@60hz gamer and my 3060 Ti is overpowered for a lot of the games I play. However, there are an increasing number of titles being released over the past couple of years where even on medium settings the card struggles to keep a consistent 60 fps frame rate. I've wanted to upgrade but overall I'm more concerned about power consumption than raw total performance and each successive generation of GPU…

I think you can get a 5060 and simply down volt it some, you'll get more or less the same performance while reducing power draw sensibly.

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.

Kind of wondering if nVidia will pull a Dell and copy Apple renaming

5070, 5070 Ti, 5080, 5090 to

5000, 5000 Plus, 5000 Pro, 5000 Pro Max.

:O

Why does 8K gaming require more VRAM? I think the textures and geometry would have the same resolution (or is that not the case? but in 4K if you walk closer to the wall you'd want higher texture resolution as well anyway, if the graphics artists have made the assets at that resolution anyway) 8K screen resolution requires 132 megabytes of memory to store the pixels (for 32-bit color), that doesn't explain gigabytes…

My understand is between double buffering and multiple sets of intermediate info for shaders, you usually have a bunch of screen size buffers hanging around in VRAM, though you are probably right that these aren't the biggest contributor to VRAM usage in the end.

Shadow maps are a good example, if the final rendered image is 4k you don't want to be rendering shadow maps for each light source which are only 1080p else your shadows will be chunkier.

Increasing performance per watt means that you can get more performance using the same power. It also means you can budget more power for even better performance if you need it. In the US the limiting factor is the 15A/20A circuits which will give you at most 2000W. So if the performance is double but it uses only 30% more power, that seems like a worthwhile tradeoff. But at some point, that ends when you hit a max p…

> Increasing performance per watt means that you can get more performance using the same power. I'm currently running a 150 watt GPU, and the 5070 has a 250 TDP. You are correct. I could get a 5070 and down volt it to work in 150ish range e.g. and get almost the same performance (at least not significantly different to notice in game). But I think you're missing the wider point of my complain: it's been from Maxwell…

> But I think you're missing the wider point of my complain: it's been from Maxwell that Nvidia hasn't produced major updates on the power consumption side of their architecture.

Is this true or is it just that the default configuration draws a crazy amount of power? I wouldn't imagine running a 5090 downvolted to 75W is useful, but also I would like to see someone test it against an actual 75W card. I've definitely read that you can get 70% of the performance for 50% of the power if you downvolt cards, and it would be interesting to see an analysis of what the sweet spot is for different cards.

And screwing gamers over by raising the prices by 2x. Fuck that.

Believe it or not, it's possible to be interested in both machine learning and videogames. That's ignoring the notion that it's somehow how screwing over gamers. Buy a fucking AMD card. They're great at gaming and you don't need CUDA anyways. Enjoy the long-term acceleration of GPU performance increases you're getting by the way. All that stuff comes from innovations made for workstation/DL setups.

Fake frames, fake gains

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

This is factually incorrect and I don't know where people get this idea from.

Just moving my mouse around, I can tell the difference between 60 and 144 fps when I move my pointer from my main monitor (144 hz) to my second monitor (60 hz).

Watching text scroll is noticeably smoother and with less eye tracking motion blur at 144 hz versus 60.

An object moving across my screen at 144 fps will travel fewer pixels per frame than 60 fps. This gain in motion fluidity is noticeable.

Saving $1000 for only a ~25-30% hit in rasterization perf is going to be worth it for a lot of people.

That would be true for the 4090, but the 3090 is even more cut down so the 5090 is about 100% faster in rasterization (based on the 4090 being nearly 70% faster than the 3090 and the 5090 being approx 25% faster than the 4090)

Many American homes already have 240V sockets (eg: NEMA 14-30) for running clothes dryers, car chargers, etc. These can provide over 7200W continuous power! I guess PC power supplies need to start adopting this standard.

You can't use a NEMA 14-30 to power a PC because 14-30 outlets are split-phase (that's why they have 4 prongs - 2 hot legs, shared neutral, shared ground). To my knowledge, the closest you'll get to split-phase in computing is connecting the redundant PSU in a server to a separate phase or a DC distribution system connected to a multi-phase rectifier, but those are both relegated to the datacenter. You could get an e…

As far as I’m aware (and as shown by a limited amount of testing that I’ve done myself), any modern PC PSU (with active PFC) is totally fine running on split-phase power: you just use both hots, giving you 240v across them, and the ground. The neutral line is unnecessary.

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…

Sure, but compute is a limiting factor.
