Sorry, this same thing was said about 13th gen.
So yes there are 3 official generations (12-14) on the LGA 1700 socket, all released in 2 years (Nov 2021 - . All 3 of them are still out there for sale, and yes there was diminishing gains with 14th gen. Who really thought there wouldn't be? We weren't even supposed to have a 14th gen RL refresh.
There's a pretty big difference between 12th and 14th gen. Like in the chart below, that's 38.1% difference in AV1 encoding from AL to RL refresh. Most benchmarks outside of games show a 20% gain.
And that, with a full node disadvantage vs TSMC.
AMD is going to lose that advantage they are getting from TSMC in 2025. We'll see how that works out.
