Threadripper already accomplished all of this years ago. My TR2970WX has 24 cores/48 threads, 48 PCI-E lanes, and it supports ECC and non-ECC RAM. My AsRock Rack board has BMC support as well.
The Threadripper series was the perfect workstation CPU. I’ve had mine for a few years and it can handle anything I throw at it, it can easily transcode 2-3 4K videos while doing multiple other things.
It wasn’t cheap though, it was like $650 on sale, originally like a grand or so.
The thing that annoys me the most is how it cares about whitespace/carriage returns. I remember back in college when I was taking a CS class, learning Python and writing the Code on a Windows PC, emailing it to myself, and then attempting to run the code on Linux. Before I learned about the carriage return conversions, I remember having to rewrite about 75 lines of code before I got it to run. 🤬
