holy sh*t, i was sold at 5,000 cuda cores, that is just ridiculous. Well, nothings stopping my wallet at this point. I know they’re generally exaggerated, but the borderlands 3 bench on their site is telling. That’s a massive performance jump between generations, potentially bigger than 9xx to 10xx

Yeah, i think i’m sold. Gonna try really hard to get work to pay for it before getting the ole moleskin out myself though.
edit: Still that 3070 with 2080ti performance is gonna fly of the shelves at 500$.

They look like absolute beasts. Happy days.

Wait, what, really? Are these real shader cores? Does this actually double performance for non-raytracing stuff like VR?

your guess is as good as mine, but it is from nvidia’s own site:
still we should probably wait for reviews

Looks like yesterday’s specifications were wrong in any case.
If the card gets a little more than double the performance of what I have now, OR allows VR SLi, either way, I’ll be happy with that.

In short…
Don’t waste money on a used 2080Ti 
Not standard, not pre-binned.
RIP 2080Ti

I don’t think VR SLI is a thing really, it does support NVLink though, but i’m not sure that it’ll do shared memory or just old standard good for benchmarks and nothing else sli.

Well the 2080ti will have more ram so if you get a good deal and would have otherwise gone for a 3070…

Most VR apps, including the most difficult to run such as DCS World, do not support VR SLi currently. It would be very helpful if NVIDIA would do something with NVLink to force multi-GPU at the driver level.

Indeed, if the 3080 sells with 10GB VRAM, then it is basically crippled for a lot of simulation things. Then again, anyone who really cares about those things should be getting the absolute best card available anyway…

Can you explain that? I’m naive as to why 10gb would be an issue (unless you mean that’s just not enough ram).

Not everyone can afford it though. tbh if I was looking for big memory on a budget (i mean a relative budget, this if gpu’s we’re talking about) I’d probably wait to see what happens around big navi release. it’s possible there’ll be an 2080ti with more memory. or that amd has something nice.

currently i’m often hitting 10gb vram use in vrchat and skyrim with mods. you’ll prbably see things that can exploit more vram in the near future (but will run with less) Jensen was talking about open world concepts that was loading textures directly from nvme ssd’s to vram at 7gb p/s

Apparently there might be 20gb 3rd party varieties of the RTX 3080.

It already takes some cautious tweaking to avoid occasionally running out of 11GB VRAM running DCS World and OVRDrop overlays. Then things crash. So it’s not an issue unless it’s just not enough for whatever you are doing.
But I wouldn’t want to risk going down to 10GB only to have DCS World push out an update that breaks my system.
@BNP Contrary to some people’s perceptions, anything more than 14GB VRAM is very much definitely plenty. It’s not a problem for VR apps, unless you run enough stuff to run out of it, which is still hard to do even for the simulation use cases. So, no, only way AMD is going to be a serious challenger is if they up the number of cores, allow multi-GPU, and/or support Smart Smoothing, FFR, etc.
I don’t see AMD doing any of those things, and I was very disappointed in the Radeon VII.

it is plenty now, (although my 12gb gets stretched a bit now and then) but who knows in 2 years or 4.

1GB more than 3080 yes, but performance wise it’s a no-brainer.
I’ll stick to my Nvidia update religion.
Skip every generation untill something is worth the performance upgrade.
1080Ti -> RTX3090 for me
