There will be no more Pentium, Pentium Gold, Pentium Silver, Celeron, etc. branded CPUs starting with the 13th generation of Intel Core processors ("Raptor Lake"):
"Intel Processor" Replaces Pentium & Celeron Brands [phoronix.com]
The new "Intel Processor" branding is intended to "simplify" their offerings for users. Intel's premium Core, Evo, and vPro branding, among others will remain. But for the basic CPUs, they will now be known as Intel Procesor.
AMD's new naming scheme for its mobile CPUs seems purposefully confusing [notebookcheck.net]
AMD has announced that next year's mobile processors will use a new naming scheme. The new system is difficult to understand and may confuse customers - maybe on purpose.
[...] So now, there will be the new Mendocino series, which are 2020's Zen2 chips brought back to life as Ryzen 7x20. Barcelo (Ryzen 7x30) and Rembrandt (Ryzen 7x35) will also continue on. Zen4, the hotly anticipated new CPUs, are relegated to the high-end as Ryzen 7x40 (Phoenix) and Ryzen 7x45 (Dragon Range).
The problem: The most important part of the model number, the CPU generation, is the third digit. Logically, the first two digits in a four digit number should be the most important ones.
AMD has not announced any concrete model numbers yet, but it is easy to imagine how confusing these number-games can be for regular consumers. For example, a customer may have the choice between a Ryzen 7 7730U and a Ryzen 7 7740U - one is based on Zen3 from 2021 and is still paired with old Vega-GPUs, while the other is a chip of the newest Zen4 generation, even though only the third digit of the model number is different. Transparent for customers? Not at all!
Some processor names already leaked before the naming scheme announcement, such as the AMD Athlon Gold 7220U, which would be a "Mendocino" APU using the Zen 2 microarchitecture [anandtech.com].
