RTX 5070 for encoding and decoding

Thinking of selling my RTX 4070 Super for RTX 5070. I have been reading about the RTX 5070 and setting aside the backlash mostly from gaming community, it actually looks like it does one thing that no previous generation of cards did. H264 10 bit 422 decoding. And it actually seems to benchmark better for productivity tasks anyway. It has 1 encoder and 1 decoder, same as the RTX 4070 Super I have, in terms of quantity but it can decode that. Every now and then, I get 10 bit h264 422 footage that is 4k which yes I can always transcode but it takes time and becomes a mess for managing files that go half or 1 tb coming off cameras like GH5. Anyone here have any experience using the RTX 5070 with Resolve?

dont do it yet, resolve does not support 50 series cards, black magic have not put out anything to tell people and no word on when they will add support either, dont waste your money as you'll have to run resolve on your onboard graphics until bm can be bothered to do an update (i got a 5080 at launch and im pissed at bm not even mentioning that it would not be supported and ignoring emails about the issue)

Oh wow, thanks for letting me know, I hope they add full support in new updates.

Per JockinWales

i was almost arguing with support as they insisted there was no issue with the 50 series cards until they had my logs then suddenly it wasnt supported, at first they even insisted that it was supported and should be stable

So wait a few months


As far as performance, the 5070 is tied with 3080 for GPU effects and only 15% faster than 4070 super. The 5070 TI seems the more compelling choice, 48% faster than 4070 super.

H265 4:2:2 decode is of course a great, and long awaited feature. But FYI if you are editing on and intel 11th gen+ CPU you already have it and don't need it from your GPU.


H.265 4:2:2 hardware encode is a feature I am not sure as many people care about. If you want the absolute best quality image to used 422 over 420, you probably are going to use Dnxhr or x.265, and certainly not NVENC.

As others have said, support for the 50 series is flaky not only for Resolve but for other programs I also use.
My 5090 does work ok and is a good bit faster but it isn't without issues.
I only bought early so i got a top price when selling my 4090 card.

THe RTX5000 Series should support both h264 and h265 with 10bit 4:2:2, thats crucial for me as a sony shooter. Sony only let you record 4:2:2 h265 if you switch your camera to ntsc and thats a nightmare for everyone in the eu, because if you record indoors you get flickering images all over the place. So hardware decoding of h264 10 bit 4:2:2 is important for a lot of people and intel quick sync does not support h264 10 bit 4:2:2 decoding. Also not every editing pc has a intel cpu with integrated graphics.

Also people shooting with cameras like GH5 record h264 10 bit 422. I know as I've dealt with these files in the edit and had my system slowed down to unusable levels.

oh wow, thats it. I've bought rtx5090 and Neurel engine always tries to keep optimizing on every startup of resolve.

And neurel engine opt. is not working. With or without neural engine optimisatin GPU effect does make same performance.

My last 3080ti could playback 30fps with speedwarp-faster and 45fps magic mask tracks on 4K timeline
New rtx5090 8.5fps speedwarp-faster performance, 23fps with magic mask tracks on 4K timeline

That neural engine does upgrade performance insanely, now i only use my GPU's raw performance

Of course Rendering and usual rendering performance is extremely good, even 3 encoder 2 decoder works perfectly fine but i know with neural engine it will be perform 5x more than this current version

Hope Blackmagic support it asap ... i really didnt know that 5 series doesn't support before purchase

The 50 series opens up the AMD option now so you don't have to rely on an Intel CPU with quick sync.
I tested my 5090 on my machine with a Intel 13900KS with Quick sync enabled and then my new build with the same 5090 card with an AMD 9950X3D and the AMD machine was a good bit faster (190 seconds vs 148 seconds).

Also hoping Resolve get things optimized soon so things can only get better/faster still.

Does that Neural engine works on your 5090? It always ask me to re-do it on every start-up and it doesn't work (disabled or enabled same performance on Neural engine tasks ) Forum members said 5 series is not supported yet. For my tests on neural engine tasks ( magic mask tracking, Resolve's native noise reduction, optical flow, etc ) 5090 is almost 3x times slower than my old 3080ti

No, I have the same problem with Neural engine where it always asks me to optimize at program launch so I disabled it for now until Resolve update the software.
I do more rendering on lots of files than heavy editing so for me, the faster render times helps me a lot.

Really disappointed with BMDs response on this. Not only is the neural engine asking to update every single time I open up DR, but they haven't implemented 10bit 422 265 decoding on the 50 series cards.

The 50 series cards are a huge deal (for non Intel users admittedly) with their encoders/decoders and they're just being ignored rn by bmd.

Complete radio silence

Really hope they haven't just forgotten about DR19 and are just moving on to 20 as that'll not be stable enough to consider for months yet.

BMD, Please don't make me go back to Premiere! (shudder)

I've seen staff say in another thread they are working on it.

I'm sure they are working on this bro. Dont worry about that, also premiere doesn't support it too nor most of GPU power doesn't support on AE too.

Yeah I hope so. Maybe some communication from BMD that they're even aware of the issues might help. As you say though, fingers crossed.

The version of Resolve that reviewers were using in January was performing poorly—it ran sluggishly and, while it could decode some 4:2:2 color AVC/HEVC formats, it could not decode others that should have been straightforward. Some reviewers even skipped testing Resolve entirely, deeming it too buggy to produce meaningful results, while others revised their reviews after a later update addressed some of the issues.

With the imminent release of Resolve 19.5/20.0, it's possible that 4:2:2 decoding has become a key part of its promotional push. This has led to speculation that the new version may not be a free upgrade—users might have to pay for new Studio version. Alternatively, a minor 4:2:2 decode patch could be released for Resolve 19.1.4 shortly after NAB and the new Resolve will be a free upgrade as usual.

Most likely 19.1.3 released on 19th of January was originally going to have 4:2:2 decode with the release of the studio drivers on 30th January but things went horribly wrong

Anyone with an intel 11 gen+ (non-f) CPU has h.265 4:2:2 decode today. As do all apple silicon users, even in free.

Your logic of requiring a new $300 check to Black Magic to get V19.5/V20 doesn't jive with me.


Will 10 bit H.264/5 support (which every camera I know of shooting 4:2:2 I know of) remain paywalled for windows users? I give 50/50 odds. 8 bit hardware decode was added in free a few months ago.

That wasn't my speculation I read it here. People know something out of the ordinary has occurred and 50 series owners are airing their worst fears due to a lack of information from Blackmagic. I don't think any of the other software that Nvidia promoted at 5090 launch has 4:2:2 decoding yet either.
