  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Hiya,
I have been reading up more about the GTX cards and thought I would share some thoughts.

So we currently have 2xTitan X cards. They cannot play 8k Red video realtime in Redcine X.
However I have tried with 2xGTX 1080 Ti cards and they can play in Redcine X.

So with the 2080 Ti I think 1 cards could be able to playback realtime with just one card. Probably good with two to help with Neat Video etc.

So about 2080 Ti vs 1080 Ti
First 4352 cuda cores vs 3584 which is 21% decrease
Memory Speed 14Gb/s vs 11GB/s so a 27% increase

Now most know the above but there is one information i recently found on Toms Hardware. And that is that for float 32 operations the previous generation could only do ONE operation at the time while the new can run them in parallell.
"To start, Turing borrows from the Volta playbook in its support for simultaneous execution of FP32 arithmetic instructions, which constitute most shader workloads, and INT32 operations (for addressing/fetching data, floating-point min/max, compare, etc.). When you hear about Turing cores achieving better performance than Pascal at a given clock rate, this capability largely explains why."

https://www.tomshardware.com/reviews/nvidia-turing-gpu-architecture-explored,5801-4.html

I am thinking that most operations regarding red files are float 32 values.

I plan on getting one card, and then maybe get one later if I need it for other operations.

Hope you've seen the thread in Recon about the new GPU's. 2080ti should do 8K decode and debayer at 1/2 res, maybe even full res, in real time at least, from what Jarred has been saying, starting in December once decode is taken away from the CPU.

Finally a quad or six core could run 8K in realtime. I've never needed my 16core/32thread CPU for anything but R3D decode, now it won't cost an arm and leg for the CPU on the next build I do.

No one has a 2000 series yet, so its only unconfirmed speculation.
 
If you don't have a lot of ray tracing work already (most of us don't) then I expect you'll get much better value from buying a 1080 card, until the 2080 cards start to lose their "shiny new glow" of being the latest toys and come down in price.
 
Im getting 4 2080ti’s next week if all goes as planed. Bought the bits and bobs for two beefed out hackingtoch tb3 machines that will get two each. I can fit three so will probably test that aswell if I get thrm going.

Tired of waiting for this mac pro bullshit.

Have a nice fight with MacOS.

Will look out for your thread about the results. Aslo hoping some one test two 1080Ti cards.


If you have a 1080Ti and get a 2080Ti and run them booth in the computer. Will the 2080Ti get slow down to match the 1080Ti?

Yes it gets slowed down by the 1080ti.

Yes, a bit frustrating spent like 40h by now and still have problems with

tb3 connectivity.
Nvidia web drivers that does not run properly. Something with using cuda causes flame to crash.

But will give it another round next week trick is apperntly to install both windows an osx to get tb3 running.

Still was nice to see renderspeed in flame on the i9
 
Has anyone recieved a 2080 Ti? Would be interesting to see how it performes in Redcine X. I could not playback 8k full debayer with 1080 Ti, however it worked with 2x1080 Ti cards.
I think one 2080 Ti would be enough though.

At what frame rate? 1xGTX1080ti is enough for Playback only, in resolve at 25 fps.

They keep on delaying the 2080 Ti. I check my email twice a day. Got one today saying they started shipping some and hope to have all the preorders out by the 5th.

It is worth noting that the RED update we are waiting for will come out later this year. So while I hope to see an improvement, I'm more excited to see the bump in my video games till the REDCINE-X Pro update comes out.
 
Posted in the MacPro thread, but thought it was pretty relevant here.

If you look on one of nvidia's RTX pages it clearly shows a Mac system. Can this really just be a mistake? Or a hint that RTX is coming to Mac, more specifically the next MacPro.

That, and the recent reports of RTX cards working just fine in OSX with boot screens without needing to be flashed. Something's definitely going on.

Rumor is that the Apple/AMD deal comes to an end in December.
