How much can a graphics card speed up the new denoise ai tool?

I had a medium speed gaming computer built for me a few years ago to use with post processing of my pictures on LR classic. At that time there were no graphics cards available at a reasonable price because they were all being bought for crypto mining. It wasn't an issue for me because at that ti e LR didn't really use a graphics card. Now with the new ai tools I needed a graphics card and wanted to know how much this would speed up the denoise tool. I couldn't find any data on this even from Adobe.  I ran a test on the same 46mp image from my Nikon Z7ii applying exactly the same settings in LR classic. Here were the results:

No graphics card installed:

Estimated time to run denoise =26 minutes

Actual time to run denoise = 12 minutes and 30 seconds 

4060 Gigabyte GEFORCE RTX graphics card installed:

Estimated time to run denoise = 20 seconds

Actual time to run denoise = 22 seconds

Computer details:

OS - Windows 11 pro

Processor - 11th gen Intel Core i7-11700k @ 3.60ghz 8 cores 16 logical processors

Desktop

RAM - 32 GB

I hope this is useful to others. If you are considering a different graphics card you should be able to use speed charts to get a decent estimate of speed.
