Thanks I'll check to see what I have set. It was ridiculously slow. I stopped timing it after about 2 minutes or so. I'd guess it took about 4 minutes.

Need for speed. Denoise is by far the most advanced of the three Enhance features and makes very intensive use of the GPU. For best performance, use a GPU with a large amount of memory, ideally at least 8 GB. On macOS, prefer an Apple silicon machine with lots of memory. On Windows, use GPUs with ML acceleration hardware, such as NVIDIA RTX with TensorCores. A faster GPU means faster results.

I honestly don't know much about Ryzen, although I'm noticing the people with the longest times (anecdotally on FM) seem to have that in common. I have a markedly worse GPU than you, and an ancient i7 and my times are around 60 seconds on my old desktop and half that on my newer M1 mac.

Upgrading the GPU will have the biggest impact. I have a 10 year old i7 system where I recently replaced the GPU with a used NVidia 2060. My 20mp OM-1 files take 16s to Denoise.

I'm going to replace my editing desktop with a Mac Studio eventually, I'm way past caring about upgrading PCs every 5 years. I've been blown away with Apple silicon...in my evaluation, my upgrade money is far better invested in that than a GPU. Just my personal opinion based on observations. I'm also dealing with files way bigger than 20mp m4/3. Doing a lot of 4k/120 editing these days as well which Mac just destroys.

I did a test. Denoise removes colour noise at 1. Opening a file with the sharpening default of 40 and no sharpening. Which file will Denoise have to work harder on?

Also if you go into Denoise with the default and come back out you are technically sharpening it twice increasing chance of more artefacts?

Can anyone with an M1/M2 MacBook Pro comment on how these new tools are pushing CPU/GPU use? Wondering if I need to consider 64gb RAM in my next laptop when I upgrade my underspec'ed M1 Pro I got with a lowly 16gb RAM.

I was in the jungle all last week photographing birds, so not only was I unable to do any testing, I was also able to get a ton of images that will *need* the denoising.

I did just do a couple of quick tests on some very noisy images to compare speed and both my Mac Studio Ultra 128GB and a 24GB Nvidia RTX 4080 take the same time on those files, wishing a tenth of a second, so pretty much margin of error--from the moment I push the "Denoise" button until the DNG is saved takes about 20 seconds. A lot of the time right now seems to be saving/creation of the DNG file.

That's the Studio with the 64 core GPU Ultra right Jeff?

It would be interesting to see how the 48 core GPU version (with 64GB I think) does given how much is being pushed on the GPU.

Thanks

I'm a tad bit late to this show as I was in the jungles of Costa Rica all last week when this came out. I got an email from a friend that let me know it was available so the one night where I had relatively faster Internet I downloaded it to my M2 Max MacBook Pro. I was with two other photographers and we all are current Topaz users, and we all agreed that the new LR Denoise is easily just as good as Topaz if not better.

Honestly, having done a lot of extensive testing of DxO, ON1 and Topaz in the last year, I'd give Adobe the edge overall for producing a very natural-looking result without too much smoothing or artifacts being created. I'm very pleasantly surprised. This doest not feel like the first effort it is--it's incredibly polished.

Could it be faster? Maybe. But a quick test on a couple machines on hand here show it's just as fast as Topaz overall--if I use the Topaz DeNoise AI standalone, it takes about 22 seconds to open render a TIFF, open it, process, and then save the file back to LRC. If I just process in LRC with their new DeNoise, it takes...about 22 seconds to go start to finish. Using the new Topaz PhotoAI, it takes even longer, about 35 seconds, and it's very hard to get rid of the odd sharpening artifacts that application seems to create. FWIW, I haven't even tried the newest version of DxO as with the limited testing I did before Adobe came out with this, I found the results to be worse than Topaz and the application to be even slower yet, never mind the odd subfolder file handling approach they use.

Based on what I'm seeing, my renewals to Topaz are over. So much nicer to have it all in one place, and the results IMO are superior.

Here's the thing: It's not the GPU from what I can see. It certainly hits that, but Adobe explicitly states that it uses the Apple Neural cores, and the Tensor cores in the Nvidia GPUs. I think this is why people are seeing some very slow performance on older Nvidia GPUs--they lack the tensor cores needed to accelerate this processing. Right now the MacBook Pros, Mac Minis and Studios all have the same number of Neural Engine cores--16. I'll verify tonight but my gut feeling is that they all have similar processing times. I did see LRC grab about 4GB more of RAM when processing the images, so as I've said before (and as Adobe now recommends), more RAM is better. I still maintain the 32GB on Apple Silicon should be the minimum a photographer should consider, and 64GB if you can afford it.

BTW, as noted above, the Studio is keeping pace with an Nvidia RTX 4080 GPU with 24GB of RAM which is pretty impressive.

Unless you have silly money and go M1 Ultra with the Studio, then you get 32 NE cores. I don't know anyone with that rig, personally

I can understand wanting at least 32GB of ram on Apple, but I'll reiterate that my 16gb M1 MBP leaves me wanting for nothing during intense processing. It's amazing how an "underpowered" M1 machine flies compared to its Intel step-brother.

Ahh yeah, good point, but you know me--I have two Ultras. I'll have to see how the Max compares to the Ultra as I do more testing. It seems like the bottleneck I'm seeing is the DNG file being written/created. Not sure what all is happening there, but it's the slow step on my Studio Ultra and PC at work.

Yes, the Ultra chips have 32 Neural cores, the Max has 16. You also drop CPU cores and GPU cores when going down from the Ultra to the Max.

What were the files from, Sony A1?

You will want an RTX card from any of the 30 or 40 RTX series or the 2060 and above from Nvidia or the Apple M1/M2, as Denoise is using the Neural engine in these GPUs to improve performance.

https://blog.adobe.com/en/publish/2023/04/18/denoise-demystified

Finally, we built our machine learning models to take full advantage of the latest platform technologies, including NVIDIA’s TensorCores and the Apple Neural Engine. Using these technologies enables our models to run faster on modern hardware.

So for those who care...the additional neural engines in the Studio Ultra models really do make a difference in overall speed. My 16" M2 Max has 16 neural engines vs. the 32 in the Studio Ultra, but they also run at a faster clock speed. On the Studio Ultra the total process from hitting the Denoise button until the DNG is saved on average takes 21 seconds; on the M2 Max it takes on average 26 seconds.

As a reminder my Nvidia RTX 4080 takes the same 21s to process the same files. The only consumer level card that would probably perform better would be an Nvidia RTX 4090, but those are $2000 video cards.

BTW, it's hard to tell when Adobe is doing the actual denoise calculations, but I think it's part of the whole DNG creation process. It's definitely different on my PC and Studio Ultra--the Studio will load an image preview of the Denise in less than 2 seconds; it takes the PC with the Nvidia card about 6 seconds to do that, but ultimately the total time to finish is very similar for both.

It looks like an M1 Studio/Ultra is a good buy for a desktop for this AI tech if needed. No point in waiting for an M2 version (next year according to some rumors) as the M2 chips have the same # of Neural Cores as the M1. Go Ultra though for twice as many.

Yes and no; I personally suspect that we will see an updated Studio with an M2 Ultra, and that should be quite a bit faster. My belief is that the new Mac Pro will use an M3 Ultra/Extreme and some add-in cards, and quite possibly one of them will be an Apple Neural Engine accelerator, similar to what we saw with the specialized Afterburner cards in 2019. Of course, that's all guessing, but I feel like it's a pretty good guess.

If I had to upgrade today and had the money for the Studio Ultra, I would go that route. If I could wait 3-6 months, I would do so, as I think we'll see an interesting announcement or two in June at WWDC.

That's interesting. I can wait (but not too long I think), certainly for WWDC though. I could also go for an M1 Studio if I see good mark downs before a new version is released.
