Feb 2022 vs Q1 2022 could be 4 to 8 weeks apart. But more importantly, processors available != systems available. System availability was not specified (I assume because that varies by vendor). When you go lower and lower in power, reference laptops have less and less applicability.
Obviously it could
be 8 weeks apart, but that would make it first of Feb versus very end of Mar availability, that's very unlikely.
In terms of systems/processors available, I don't think the press release meant the CPUs are available starting Q1.First, it would be weird to announce that they are making the CPUs available to OEMs like this. Second, this quoted sentence wouldn't make any sense.
Built to take on simultaneous everyday workloads, business productivity and even gaming in full high definition (FHD), these 12th Gen Intel Core U- and P-series mobile processors will be available in the first quarter of 2022, including devices designed for both Windows and Chrome operating systems.
I read this as a mistake in the write-up and it should read like the line for the H processors:
Designed for enthusiast gamers, creators and engineering professionals who want to push their laptop performance to the next level, the new 12th Gen Intel Core H-series mobile processors deliver desktop-caliber performance on the go. They will power systems available starting in February 2022.
In other words, the U processors will be in devices which will be available starting Q1.
