Yes, your Xeon from 2013 example would be nowhere near the 2021 CPU from Apple. The outdated Xeon Apple had in their old laptops - a year behind everyone else, is also slower. The Xeon W-11955M however makes the M1 look like a kid's toy. In fact, if you remove 2 cores from that Xeon, you'll have my 6-core Xeon. Which also smokes that 10-core M1 in a bong.
I'm also not sure why you're sarcastic about ECC RAM. I have 128GB of RAM in my laptop. If it wasn't ECC, I'd have crashes in my VMs and errors in my calculations. When you go 32GB+ and actually use the RAM, anything that doesn't support ECC cannot be taken seriously for professional use. Like the M1 Max.
