I am asking for a name of one that has been demonstrated to actually do that. Not promise. Not “on paper”. Actually do. Extra credit if it actually exists in a store to actually buy. Today.

  And yet somehow you are sure such things exist?

    Look, you're probably right but there's no need to be so annoying about it.

        There's nothing nonsensical about the claim that there are AMD and Intel systems using 128-bit LPDDR5-6400. AMD's mobile processors started supporting that config last year, so in spite of this year's mobile processors being a bit late the market is already full of systems so equipped. Intel's mobile processors as of earlier this year also support this memory configuration and speed, and systems have been shipping from multiple vendors for well over a month; they're not exotic or hard to find. There's even at least one announced but not yet shipping Intel-based system that will use LPDDR5-7500!

  It's called "overfitting specs". They ask for a very specific set of specs that only Apple laptops have and ignore anything else. If you can find anything that competes they'll move the goalposts and complain about touchpad or something else.

Sorry, still not clear exactly where your goalposts are. Is there a public benchmark where M2 scores above 100GB/s that you'd like to see comparable runs for a recent x86 mobile platform?

  Not sure about the M2, but here's one for the M1 Pro/Max: https://www.anandtech.com/show/17024/apple-m1-max-performance-review/2 https://www.anandtech.com/show/17024/apple-m1-max-performanc... For whatever reason, it isn't so easy to find real-world memory bandwidth results for consumer stuff; it's a fairly standard benchmark for server hardware, but less so for consumer. Here's one for an old Ryzen 9: https://www.anandtech.com/show/14605/the-and-ryzen-3700x-3900x-review-raising-the-bar/2 https://www.anandtech.com/show/14605/the-and-ryzen-3700x-390..., but couldn't find anything current offhand.
