Intel and AMD have for years released a new mobile "generation" every year (like 7xxx -> 8xxx) even when there wasn't anything new, and in 10th gen Intel provided Sunny Cove and gen11 graphics for the U series when everything else was some Skylake derivative. But what AMD is doing now is worse, selling Zen 4 and RDNA3, Zen 3+ and RDNA2, Zen 3 and Vega, and Zen 2 and Vega all under the 7xxx umbrella. They did provide enthusiasts a way to know the CPU microarchitecture with the 7x4x naming scheme, but as someone mentioned the stores didn't offer a filter for this. Moreover if a user settles for 7x3x, it could be Zen 3+ and RDNA2, or Zen3 and Vega.
I feel like AMD is using this naming scheme in part to pretend to be ahead of Intel by more than they really are. Many enthusiasts point out that AMD is using TSMC N5 and N4 while Intel is still stuck with Intel 7. But a lot of AMD's latest 7xxx chips are not 7x4x, so a lot of what AMD is still making is N6 and N7. So if Intel actually ships Meteor Lake on Intel 4 next month for U-series laptops, Intel may actually be pretty close behind AMD at least in the overall laptop market.
