NVIDIA ‘Ampere’ 8nm Graphics Cards

As more and more performance numbers come out my hype is scaling back more and more on Ampere.

The 3080 is about 30% above the 2080 ti and needs 30% more power...where is the improvement?

The 3070 has 2/3 of the shaders and less bandwith...it might come in 2080S performance rather than 2080ti level

It seems with the 8nm node change they have zero efficiency improvements
 
approximately 35% gains on last gen in purely rasterization comparisons seems pretty reasonable to me, it's about what we'd expect from a good refresh. We know that gains of pure 2x performance while some kind of holy grail, rarely ever actually happened in practice.

I think the general principle here however is that our demand for rasterization is at a sensible limit right now. The 2000 series had 4k capable cards at 60fps for most games and they already had large sections of the GPU dedicated to non rasterization ops like the RT/Tensor cores, they could have in theory gone with more rasterization performance for the same chip size with a different architecture, but they didn't because it would have been hard to sell such a GPU to the average person. Keeping in mind that 4k@60fps is already a very high end expectation, some vanishingly small percentage of gamers even use this.

Despite doing what they did they still came out with 4k capable cards, and the 3xxx series even improves on that. If anything I think they probably have gone with say a ~ +20% improvement in rasterization this gen trading those transistors for more RT and Tensor cores and got better RTX performance and that would have been a better deal for most people at this price point. And that same line of thinking is what leads to RTX benchmarks being more of the focus.

What? I'm sure 2080Ti owners could chose to increase performance by 30% for a 30% increased power draw they would be all over it, you are also ignoring the RTX improvement and the much lower cost

Yeah i must admit I like shiny new things but the sensible part of me is think wait another year for the 20gb 3080ti to be out and there are more games which use/support RT/DLSS.

To a degree it was the same with the 2080ti. It offered RT and DLSS but we really havent seen too much use of all of that and the 2080ti really didnt have the power so for the majority of the last 2 years people have just had a small gain in rasterization performance of the 2080ti over a 1080ti.

You can easily fall into the same trap with the 3080 again and kid yourself that you are going to see 50%+ gains in RT and DLSS and then when you come round to upgrading again, you realise you have barely played any and most of your gains was only 20%.

Ampere is a half step in a tick tock cycle that much is clear as daylight. Wait for RTX4000 on 5nm with multi chip module = 100% faster than RTX3090, you can quote me now on this and take that to the bank

What i'm saying is the perf/Watt didn't increase at all..and that's with going to 8nm process.
And the cost is not lower the cards are coming at the same price as the "overpriced" Turings..just now they bring better performance uplift.

These are good and powerful cards but not world changing, and not even close to the NV hype slides.

Is that what you plan to do then?

I will upgrade to the 4070/80 from my 3080, so does not make a difference to me.
