Made a spreadsheet to keep track of all the rebrands and equivalent SKUs of AMD and Intel laptop CPUs released recently going back to Zen 2 and Alder Lake. For the sheet, any CPU SKU considered equivalent has the same key specs, those being CPU cores and architecture, iGPU cores and architecture, and L3 cache capacity, while things like TDP and boost clock can vary for each individual SKU

Some interesting take aways:

- the AMD CPUs with the most "equivalent" SKUs are the Ryzen 7 7840U (most recently released as the Ryzen 9 270) and Ryzen 7 6800U (most recently released as the Ryzen 7 170), each with 12 respectively.

- the Intel CPU with the most "equivalent" SKUs is the i7 13700H (most recently released as the Core 9 270H) with 9. (Edit: It turns out that even though Raptor Lake and Alder Lake mobile CPUs are different in stepping, they are practically identical in everything else, so if you additionally count the Alder Lake H SKUs with the same specs as the 13700H as equivalents, that brings the total equivalents up to 14)

Given the complete mess of naming, it's likely I missed a few SKUs, so the numbers for the two above may even be higher; these are mostly just the CPUs I could find on Intel and AMD's websites. Also, the sheet excludes PRO and desktop-class chips like AMD's Dragon Range at the moment, might add them at some point in the future.

Single/Multi-Thread benchmarks are PassMark. GPU benchmark is 3DMark Time Spy (Graphics). Only covering the most common <30W CPUs since 2018, no low/high-end or discrete GPUs. I may do a low-end chart in future.
