Whether it's substantially better for deep learning depends on whether they chose to neuter fp16 like they did in all other consumer GPUs. The main bottleneck is not actually the size of the model per se (sizes of the models have been mostly going _down_ as of late), it's the size of the batch during training. Both batch size and model size determine the size of the main memory hog: activations that you need to keep…

I wasn't aware that the Jetson TX1 and TX2 supported fp16; that's interesting and good to know. Thanks for the heads up.

IIRC all recent NVIDIA GPUs support fp16, it's just that the perf of fp16 is severely hampered on "consumer" grade hardware, so the memory/perf tradeoff is not viable. I mean, on the one hand I can see why that is: fp16 is not terribly useful in games. But on the other, it's probably nearly the exact same die with a few things disabled here and there to differentiate it from $7K Tesla GPUs, which as an engineer I find super tacky, much like MS deliberately disabling features in Windows Home that don't really need to be disabled.

Titan V is a $3000 card. Getting close to that performance on a $1000 card is a big leap forward.

Good point, but what about the comparison with the old 10-series Titan Xp (released at $1200)? The 20-series improved peak GFLOPS perf by a meager 10%. I still would have expected more from upgrading from 16nm to 12nm. I guess floating point perf wasn't a priority for Nvidia in this microarchitecture refresh...

Much of the silicon is now used by RT cores and tensor cores. These were not on the Titan xp, for better or for worse.

Why would we want raytracing as for 'gaming' as opposed to the rasterizers we have now? Is this a gimmick or are there algorithms for post processing and the like that could take advantage of this?

As the other reply said, currently lighting and shadows in games is a huge mixed bag of tricks. Raycasting would make everything simpler and more robust... and slower.

Any clue on how this thing will compare to a 1080 TI?

In terms of real time raytracing the RTX will blow the GTXs out of the water... For anything else? Remains to be seen.

For fp16, int8 and int4, the RTX blows the GTX out of the water. For fp32 it's a tiny increase. The memory bandwidth is about 40% higher as well. You'll always find people complaining about each release, but overall I think this is a solid card.

Collapsing? Nocoiners lol

Wow you have really compelling arguments as to why crypto isn't collapsing! Thanks you for you insight

I suppose it’s collapsing up since 2009?

Since the post with the product page got merged here: https://www.nvidia.com/en-us/geforce/graphics-cards/rtx-2080... Most of it is dramatically lit renderings of fans and vacuous marketing-speak of course, but there's a tidbit near the bottom of the page about NVLink I find interesting. "GeForce RTX™ NVLINK™ Bridge The GeForce RTX™ NVLink™ bridge connects two NVLink SLI-ready graphics cards with 50X the transfer ban…

> Do you think this will be the GPU generation when consumer motherboards capable of pushing things to the GPU by NVLink will appear as well? first you'll need CPUs that support NVLink, and that's currently limited to the not so consumer oriented POWER9.

NVLink works fine between GPUs even if the CPUs are x86. Just look at the NVIDIA DGX boxes/stations. https://devblogs.nvidia.com/wp-content/uploads/2017/04/NVLin...

Putting AI/ML aside, I have a question for graphics experts or/and gamers: what is the practical [1] ceiling of the current champion, the 1080ti? I was under impression that that card already was much more than most people needed. In other words, is the new generation only useful for 4K gaming? [1] By "practical" I mean on 1440p@144Hz monitors.

I think the purpose of this card is less to allow for an upgrade to 4k (the boost in speed for raster stuff is pretty trivial), but rather to enable the switch to ray tracing as a rendering tech. So you should see a visual improvement in your gaming at the same resolution/hz, rather than an increase in res/hz.

I am usually able to keep a card for several generations before I can't get 60fps at 1080p in games anymore. Unless you're a professional gamer I don't get the appeal of throwing that kind of money at a card.

if you have bionic eyes, you need 200fps... some people use video cards for other purposes, also.
