It's an unbelievable mess. I think I shared a Tom's Hardware article when it was announced, and he went out of his way to express his frustration at how bad the naming is on Intel's side. It was already bad before, and somehow they made it worse-- even more confusing.
AMD is naming their merch as sensibly as Apple and Playstation: Zen, Zen+, Zen 2, Zen 3, etc. Fucking beautiful. Even when they have glitchy skips in the processor models themselves because of laptop/mobile products (i.e. Ryzen 4xxx and Ryzen 6xxx just got skipped for desktop), we can all refer back to the architecture, and grasp the relative sequencing. Nobody struggles. So easy.
Meanwhile, Intel has embraced the Microsoft Xbox naming strategy. It seems designed to confuse people who are even passionate hobbyists.
"Hey, guys, guess what? We're rebooting naming! We're gonna call it Core Ultra!"
"Oh, okay, so it's going to be the Core Ultra 1st gen?"
"No, we're going to put hundred in the name."
"Oookay. So then the Core Ultra 100? Weird, but sounds great."
"Yeah. But, um, wait, no. Also an S. Yeah, an S sounds good. Put an S in it."
"WTF? Whatever, okay, so the Core Ultra 100s series?"
"Yep."
"Great. Sounds good."
"Just one little thing."
"Please stop."
"It's the 200s series."
"Oh, gotcha. My mistake. I'm embarrassed. I totally missed the 100s line that preceded it."
"Nothing preceded it."
