Here is a real world performance comparison of my typical Lightroom workflow.

I created a new LR catalog collection, imported 487 24MP RAW photos from a Sony a7 ILC, applied lens and image adjustment settings to the first image then synced those settings to the other images, then exported those images as 144MB 16-bit TIF files. I performed this test on both my MacBook Pro 2014 and MacBook Air M1. As I assumed, the M1 blew away my old Intel i7, but it is 8 years old now. I also ran Cinebench analysis and will put them below, but as stated earlier I don't really know if they mean much when it comes to testing M series processors.

MacBook Pro i7 15”, 2014, 16GB RAM, 256GB SSD
vs
MacBook Air M1 13”, 2020, 16GB RAM, 1TB SSD

Step 1: Copied 487 RAW photo files (12.28GB) from T5 external SSD to internal SSD on each computer.

01:16 mm:ss, MacBook Pro 2014 = 161 MB/s
00:34 mm:ss, MacBook Air M1 = 361 MB/s = 224% faster

Step 2: Imported the 487 RAW photo files (12.28GB) into the new LR catalog collection "Workflow Test".

00:23.35 mm:ss.ss, MacBook Pro 2014
00:13.96 mm:ss.ss, MacBook Air M1 = 167% faster

Step 3: Synced the lens and image adjustment settings to all images.

02:31.90 mm:ss.ss, MacBook Pro 2014
00:23.94 mm:ss.ss, MacBook Air M1 = 635% faster

Step 4: Exported all images as full size TIFFs (approx. 70GB).

30:45.93 mm:ss.ss, MacBook Pro 2014
12:24.19 mm:ss.ss, MacBook Air M1= 248% faster

Here are the Cinebench scores:

Single Core: MBP 2014 = 722 pts, MBA M1 = 1512 pts.
Multi Core: MBP 2014 = 3647 pts, MBA M1 = 7354 pts.
MP Ratio: MBP 2014 = 5.05 x, MBA M1 = 4.87 x.

ETA: I forgot to mention that the MacBook Pro 2014 ran too low of SSD space and only exported about 440 TIFs rather than the 487. So that means it would have taken longer to finish than it did.
