While this is absolutely true of the comparison between the base M1 and base M2, and likely mostly true of the comparison between M1 Pro and M2 Pro (though, I'd argue that standardizing the number of efficiency cores between the base SoC and the Pro/Max versions DID help); it's not as true for M2 Max and M2 Ultra which are both dramatically better than their respective predecessors. Apple's scaling from the base M1 to the higher end SoCs wasn't great. They seemed to fix that with M2's higher-end SoCs.
With what? Unless you've got 9th or 10th generation Intel parts lying around, it's going to be an uphill battle just to make it work and, even then, your days of support are clearly numbered. Apple is on the march to drop Intel support now that (a) they no longer sell Intel Macs and (b) now that, barring the iMac Pro, you only have 2018, 2019, and 2020 Intel Macs even supported for Sonoma (and I'll bet we'll see them drop even more Intel Macs next year).
