Denoise AI very slow in LrC, Lr, and Camera Raw

[LVBuzzy]

Hello,

The new Denoise AI takes 13min each photo in all three raw photo editors. I had some updates from Intel so I installed them and the time came to 8min each photo. All the videos I've seen on YouTube take about 15 to 25 secs. to complete. I'm using a Dell Inspiron 3670 with 500GB of SSD and 1000GB of HDD. Windows 11 Home Version 22H2.
Processor Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz 2.81 GHz
Installed RAM 24.0 GB 
System type 64-bit operating system, x64-based processor
My system is pretty old and I don't want to purchase a graphics card. Does anybody have any ideas??
Any help would be appreciated.

If you use an old system and don't want to purchase a better graphics card, then the only idea I have for you is make a lot of coffee for while you wait for denoise to do its job.

The parts that accelerate AI Denoise the most are good and recent graphics hardware, and machine learning acceleration. The PC graphics hardware that tends to run AI Denoise the fastest tend to have both, such as an Nvidia graphics card that includes Tensor Cores. Those graphics cards tend to be very recent. When you see an AI Denoise result on YouTube that’s under 1 minute, chances are their graphics hardware will be of that type, and less than 2 years old.

Although I use Macs, the differences are similar. My old laptop has an 8th generation Intel Core i5 with integrated graphics, a similar processor to yours. For a 16 megapixel raw photo, it does AI Denoise in about 3 minutes. My current laptop, about 1.5 years old with graphics on an Apple Silicon processor, can AI Denoise the same photo in about 18 seconds.

This has been discussed numerous times already - a site search would have saved you the need to post at all: if you want reasonably quick Denoise AI processing, you need a graphics card that's up to the job.

Adobe unofficially recommends something with 8gb+ of RAM.

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.

Cores, tensor, and all of those terms are way over my head.  So it would be very helpful if you or someone could provide or link to a list of Nvidia & AMD that would meet the need for reasonably fast AI performance on a Win10x64 machine.  Ideally under $600 for cost.

Nvidia RTX 30-series. From 3050 (cheap) to 3090 (expensive). Take your pick.

They all work well for this, but the more expensive the faster.

Thanks for the recommendation. Now I'm wondering if the "TI" designation
for Nvidia means anything more than just stepped-up performance, and if it
is worth the extra $$ for it. My work is almost all still photo editing of
large 45-60 files in Nikon Raw. I don't see any failures in my older GPU
(ancient Geforce) except now that AI is so prevalent and likely to become
even more so, I don't mind spending $500-$600, but just want to be sure I'm
spending on the right cost/performance balance.
