Adobe recommends doing DeNoise first, But the order does not matter. Any edits applied before DeNoise will also get applied to the DNG. If you crop before DeNoise, the DeNoise will still get applied to the whole image so you won’t be saving any time in the DeNoise process by applying a crop first.

I tend to decide this based on the ISO of the photo (I shoot a Canon 90D).
If I have taken it at very high ISO, and hence high noise, I will always Denoise first (using the new Denoise AI). I will see the colors and details better.
Then I crop. And later sharpen. BTW, setting a proper WB for high noise indoor shots needs to be done very early in the process, and usually after Denoise.

If low ISO and low noise, it doesn't really matter. As Cletus said above, LR sets the order if I export. So most of the time I crop first to get a good sense of the photo's elements. Then I generally run denoise and sharpen in parallel.
 
I believe you should do Denoise before masking and healing. I use Auto and then tweak that panel. I have a preset to take sharpening to 0 as I prefer to work in the Enhance panel with no sharpening. It will show in Enhance but as Clee pointed out all settings are stripped during the Denoising process and put them back when l the DNG is created.

The size in the Enhance view is about 240% I think. If I leave sharpening on it seems like I have to push the slider more and it will eventually it will start to effect fine detail. So if there is a bit of noise after Denoise and after sharpening it’s no big deal. I don’t mind a little noise and you can control that a bit with the masking slider in the Detail panel.

Also if I want to get rid of more background noise I’ll go into Masking. I mask the background and reduce Texture/Sharpening and increase NR manually.

So basically I just do the Basic panel adjustments only and then Denoise. Over the years watching tutorials, etc it is suggested to do sharpening last at 100%.
 
There are two approaches, that both have their pros and cons. The first approach is to Denoise first, and then only edit the new denoised DNG. After all, that is the only image of the two that you are going to use. The other is to edit first, in order to see if Denoise is even necessary. If you do not lift shadows a lot or have to increase the exposure, then you may find that you don’t have to use Denoise at all.
 
Yes I don’t Denoise unless I need to . If Manual denoising is sufficient I go with that.

The Denoise tech has been very helpful and competition between companies has only been a benefit to us. I think it can get out of hand seeking perfection. I’ll take an image with a little noise over a perfect one that starts to look plasticky. Looks more natural.

Steve Perry put out a great set of LrC/PS videos where he states a little subject noise can add detail. Example - wildlife. A little background noise will prevent posterization when printing.

If I feel like it I’ll wipe out background noise using masking for web presentation only.
 
I’m not a Pc user but it’s all about processing power and the graphics card.
 
If you know you need to ai Denoise a lot of images then you can run Denoise in batch mode. Just let it run and come back when the batch process is finished.

On Windows, a modern GPU is needed for modest performance… rtx4060 might be a mid range sweet spot. I got an Rtx 4070ti.

There is a long thread which discusses GPUs… will post a link later. The discussion includes sample performance stats for a specimen image on different spec machines.

Expect this to be a fast evolving area in terms of GPU and cpu architecture, shared memory and fast evolving ai based software features.
