If I actually planned on gaming at 4K, I might wait for a 20GB variant, or a Ti, or whatever they are going to have, but right now I'm on 1440p, and likely to stay there for the time being. But I also have other reasons to get a 3080, because I do use productivity tools, and of course I need something to work on AV1 decoding, so that I can finally make a worthwhile LAV release again.
I agree that on 1080p its mostly nonsensical, you can get a 3070 there for high-end performance.

Interesting that Digital Foundry accepted their mistake or "mistake" to benchmark Doom Eternal to highest Texture Settings at 4K that were simply above the 8GB of 2080 and the performance difference from 3080 was about 100% or even more due to limited memory of course.
Using a slightly lower setting "ultra" in order for textures to fit in the 8GB VRAM the performance difference is around 70% like the average of 4K gaming. If 2080 was a PCIe v4.0 card tested on Ryzen platform in order to support PCIe v4.0, the performance difference could be less. But I also see some reviewers like Digital Foundry that are trying a little desperately to increase the hype, comparing a 3080 vs a 1080 card of 2016! Oh, come on guys...You can do better than this!

For 1080p probably a 3060 will be enough
The rest is really good news, this card is a beast in every way.

Yea for 1080p 144hz gaming I have my monster Alienware Area 51m with a 2080 so I'm covered there. I agree about the memory, Nev, but, I'm not waiting. I think that 10gb of GDDR6x will be fine for the majority of 4k gaming. And if after a year or 2 it isn't, ok, well I can upgrade again to something better at that point. I don't necessarily buy the October surprise rumors about a 20gb 3080 unless AMD hits a homerun which is looking increasingly unlikely. AV1 support would be nice, though. And if you have a 3080 I can be sure it'll work well for me when you release it. Sweet

At least the driver is released. But no humans were able to buy any cards. They were sold out in microseconds, all snatched by bots and are now up on eBay. WTF Nice job, nVidia. Way to push people to consoles. At least those pre-orders are easier to get.

Keep checking other cards on BB because I saw another one come up available that had been out of stock earlier. I'm waiting for something to show up on Dell so I can use my $400 in coupons & credits I have available. I have no idea when they will start selling them. |

Jim explains Ampere cuda cores one more time. Interesting stuff in it: - 3080 has ~3x cuda cores of 2080, but only 70% faster - according to nvidia, ~25% of instructions are int out of all - since the new path can either run fp or int, and int are 25%, this path can be occupied 50% by int

Games (and game-like benchmarks like 3DMark) are often being limited by something else rather then pure FP32 performance. More shader-intensive workloads would benefit from the additional cores more. Maybe future more graphically intensive games will benefit more from it.
Some productivity benchmarks have shown the real power of the massive number of FP32 CUDA cores, but of course for that to be meaningful an application has to be able to use it. Interestingly, AMDs Fiji architecture from years ago had the same issue. They had a lot more potential shader power then they could get games to use. Todays use might be limited, but future use, who knows. Free shaders for RTX IO and stuff. But of course one shouldn't buy hardware on account of future what-ifs. (Also, I can't watch Jims videos, his accent just drives me crazy)

You don't need to watch Jim.
You only need to read my posts here, I've been telling you the same things from day one BEFORE he releases his videos. Now, regarding the gaming workload analysis, the 25% of INT commands mentioned above is wrong. The figure given by nVidia when Turing was released back then at 2018 that was the first architecture to execute INT+FP at the same time was around ~35 % or so to speak 1/3. That's why the 30TFLOPS become 20TFLOPS and the number of CUDA cores follow the same pattern of 2/3 real-world number compared to Turing. Now I have some info/news/prediction for Big Navi. It seems that the model that will be announced on 28th of October will be a 60CU - 64CU die that could possibly reach 2.4GHz for the 3 fans edition of 300W+ TDP. It will have 256bit bus with 16GB of GDDR6. I'm under the impression that will beat 3080 at both 1080p and 1440p resolutions but will lose a little at 4K. AMD will release later the full die of 80CUs using HBM2e memory and will beat even the 3090 card even at 4K.

So, mostly good news with this new driver. More or less. When you play an HDR title now, it'll start out as SDR and then switch to HDR mode and then enable HDR. Those of you who aren't familiar with the work around for the previous few drivers of starting a movie, stopping it, and playing it again are probably wondering wtf I'm talking about, but, they've essentially appeared to "automate" that process. The metadata is being sent correctly now, as well. Hooray for small miracles. Now for the not so great stuff. If you bring up your player's UI, it'll take you out of HDR into SDR. But we've seen that behavior quite a bit before. It's whatever. I can live with this current driver. And hey, if I ever do manage to land a 3080 in the next year, I'll be all set. LOL

Thanks for testing so quickly, bud! So, are we back to using NVidia's API for HDR with this driver, or does it still switch to OS HDR? The player UI bug has been around since early this year, so I guess that hasn't been fixed yet.
