It is worth noting that the benchmarked Snapdragon X2 Plus ran on a reference platform, while testers used commercially available products for the other chips. This is a key caveat, as results can vary widely depending on chip binning, cooling, power limits, SSD speed, memory latency, and installed apps.

What this means is that performance with real devices will likely be even worse.

With the X Elite we also had benchmark results on "reference platforms" that were never hit on real devices.

Hardware vendors also tweak the software stacks on their reference platforms to cheat at benchmarks. I once caught some Intel "improvements" to the Android Java implementation that broke thread safety in a number of regex functions which had been driving some of our app devs nuts.
