nVidia GEFORCE® RTX 2080 Ti

PostTue Aug 21, 2018 4:40 am

Comments?

Thinking of preordering this one, I have a GTX 1080 Founders Ed. today, would it be possible to keep that in the computer for, say, display, and have the 2080 TI card do my compute? Would it significantly improve Resolve 15? (I have the studio version)

The 1080 is no slouch either. Before you invest in a new card, check your bottlenecks in practical work.
A lot of the load balance depends on the codecs you use, the effects and filters and on data throughput.

There is no single best configuration for Resolve – well, maybe, the best of everything – but if money is limited you'll need too see where your typical workflow will profit most.

if you do not see "out of memory" errors with your 8g card now, then adding more VRAM is a complete waste

adding more compute power tho, is not a waste if your GPU's currently are bottle necking your workflow, are they in taskmanager, do they every hit 100% sustained in typical use?

My current bottleneck is my CPU. I've a 16-core i7-7820X, and it's at 100% during rendering and editing/Grading.

Those cards are really sweet..

But the 1080ti is plenty already...

Good news is that it might lower the 1080TI prices. RTX launch was careful not to compare to GTX.
I'll wait for comparison benchmarks and skip the hype.

I would say very opposite. CPU and drive is not real issue. Add NR and your GPU is done quickly.

I say this in jest, but your sig doesn't list drives. :D

With 2TB NVMe drives available for $800, you can inexpensively make a 16TB RAID0 media drive that can read >20GB/s. That's enough bandwidth for >80 4.6K RAW tracks. I doubt 4x 2080 Ti's would be able to keep up.

I didn't read too deep into all the specs but from my initial impressions, while they will be faster than the current gpus, they won't be leaps and bounds better. A lot of the hype about this gpu is about ray tracing which is used in 3d modeling applications (and gaming) but that isn't used when color grading in resolve.

My expectation is maybe somewhere between 20% and 30% increase over the 1080ti, in regards to performance in resolve.

depends upon machine spec's / raster really

dual 12c 2697v2 / dual 1080ti /SAS array with 16 disks... NR playing RT in a UHD timeline is not really an issue anyway for me, i just don't use NR much because i'm not a fan of soft / plasticy images ;-)

if he's already seen the CPU as the bottleneck, then why spend coin on a GPU, esp when the current GPU is constrianed by the CPU?

Yes, but when you forget about RED sources then it's way easier to deliver CPU power than GPU power to Resolve.

Is there any use or future use for the Real Time Ray tracing engine in the RTX 2080TI in Resolve and or Fusion (BMD?)? I built a new system recently and it is fast but have been limping by with a slower card until prices came down from the Bitcoin highs. I can hang on until the RTX2080TI ships but maybe 2 GTX1080TIs would be a good deal and nearly as fast as 2 RTX2080TIs especially if Ray Tracing makes no difference to Resolve now or in the future. I would like to be comfortable doing reasonable 4k work.

I'm personally holding off judgement until I see some real world benchmarks. The fact that nVidia, came up with completely new benchmarks that the old cards where never designed to be good at gives me a great deal of pause.

The boost clock is only 3% greater, so unless all the ray tracing tech is some how utilized by Resolve, I'm not seeing a very substantial improvement.

Code: Select all
                       1080 Ti     2080 Ti     Diff
CUDA Cores             3584        4352        +21%
Boost Clock (MHz)      1582        1635        +3%
Mem. Speed (Gbps)      11          14          27%
Mem. Interface (bit)   352         352         0%

Yes, most informed commentators are advising everyone to hold off until the tests have been done.

Looking at the CUDA core-count, the new RTX2080Ti looks as if it may be only slightly faster (certainly the "bang per buck" will remain much better for the old 1080Ti).

As for the raytracing... well unless Fusion is rewritten to incorporate raytracing (unlikely) then I doubt anyone will see any benefits from that. The Tensor cores (AI) may be somewhat more useful... if they can be accessed as a matrix of computing blocks and not just a monolithic unit.

I was holding off until the RTX announcements/launch but if I see a good 1080ti going for the right price I'll probably grab one now. Sadly, the prices of the 1080 and 1080ti are unlikely to fall much (if at all) and I suspect that's exactly how NVidia wants it.

Puget systems put out an article reviewing the 2080ti and the 2080 in resolve. They also just put one out on the 2070. https://www.pugetsystems.com/labs/articles/DaVinci-Resolve-15-NVIDIA-GeForce-RTX-2080-2080-Ti-Performance-1238/

you are supposed to be at 100%, it's called optimization, no matter what CPU.

Common misconception, not all tasks have no speed limit. Playing a media file will only use as much CPU as is required to do real time playback. For something like 8K RED, this is a lot, but for something like 8K DPX, it's almost nothing.

He said he is at 100% during rendering. :)
That's when you want that 100%. For the rest I am with you.

FYI: Your CPU is an 8-core, not 16-core.
If that's your bottleneck, you need to invest here first before you will get any benefit from a GPU upgrade.

I'm in a similar situation and will upgrade from a 6x 4,2GHz to a 10-core with similar OC performance. That will help me with higher res RAW material and final delivery got stay in time.
