Is anyone buying a 4090 to use in Resolve?
Early days I know but just curious and eager to see the difference in render times (with Noise Reduction) over the 3090.

I believe I saw that it's like 40% faster which is pretty insane. And considering the price is less than a 3090 was just a couple months ago...I'd def go for it. Not sure how I'm going to fit one inside my laptop

I would love to, pending funding.

Thought about it, but nah… might upgrade to 3090 from 3080 while prices are good. 4090 too expensive and seems a big middle finger to consumers… plus no 4:2:2 decode really irks me because I’m on a 9900k so I’m still doing that in cpu only. Would have been the only thing making it worthwhile. I find the 3080 plenty speedy enough for 4K, but I crash from vram starvation a lot.

Edit from the future (Dec’22): So I was wrong… I played checkout chicken on launch day and ended up getting one. Built a whole new 13900k system around it. No regrets… except for switching to windows 11. Hate it.

Yes. Probably. I want to know more about the next DaVinci release and the benchmarks.

I am getting one since I skipped the 30 series.

$1599， Dual NVENC Decoder&Encoder， but seen like still without 4:2:2 Decoder&Encoder。

CUDA up to 16000+， would that be good with Noise Reduction?

naaaah, I just got a 3090ti at decent price, I'm skipping the 40xx series....

Nope, not worth it if it doesn't workflow options for me. I was hoping for better hardware decode like John Porter.

Was hoping for better hw codec support. Disappointing about that. Coming from 1080ti, 3090 or 4090 will both be an great upgrade. I will wait for benchmarks and see if the extra cost of 4090 will be worth it. If not I'll do a 3090 at a reduced price.

If it's better codec support you're after (and you're not already running a 12th or planning to run a 13th gen Intel CPU) then the new ARC GPUs look very interesting. They are claiming parity (performance-wise) with the RTX3060 so not strong enough for a lot of folks but if you could run the ARC and an RTX in the same machine it would be kind of nice for Ryzen users. Otherwise, just stick to the latest Intel CPUs with all that wonderful iGPU codec support and use your RTX for the rest of the load.

It has a dual encoder. But we need to know what is the real improvement.

No hardware decoding encoding for 10bit 4:2:2 is indeed a black eye.

True. This is what I'm more likely to do. The Arc A310 looks like a good card for that. Single slot and only 75W. Meaning it doesn't need any additional power cables and has all the codecs the bigger Arc cards has. Will likely be pretty cheap too.

How would Resolve function with a 3090/4090 and an ARC A310 in the same system?

ARC A310 only has 4GB of VRAM. Usually, Resolve can only utilize the VRAM capacity of the smallest GPU in the system. For example if you had a 3080 and 3090 in your system, Resolve would only use 8GB of VRAM when using both GPUs for image processing.

Can Resolve only use the 4090 24GB of VRAM for all image processing and dedicate the ARC card solely for codec decoding?

You can't mix GPU types.

Except that you can use intel quicksync to decode and RTX for everything else... but it is something BMD would have to support directly in the software, and it's unlikely to be a high priority what with the state of ARC drivers.

But I would probably be content to sacrifice render time for a more responsive editing/grading experience with a non-exorbitantly priced GPU with more than 12G of VRAM so resolve doesn't keep crashing on me.

1.No hardware decoding encoding for 10bit 4:2:2
2.Decoder still GEN5 like 3090;
3.Dual Encoder，but only support AV1/H.26x
