New names for manufacturing processes at Intel
At a presentation event, among other things, Intel announced new names for CPU manufacturing processes in connection with a roadmap. Even wccftech as well as the PC Games Hardware report about it. It’s not about the model name like Core i5 or about code names for CPU families like Kaby Lake, but rather about designations that are important for experts or very interested hobby observers.
End customers will rarely come into contact with the new names because they are involved in the production of the CPUs. A manufacturing process is specified in nm (nanometers) – the smaller it is, the more efficiently a CPU can work because the components are even more delicate. However, the smaller the manufacturing method, the more difficult the manufacture of chips is. The currently smallest production process at Intel is 10nm +, it is currently used in Xeon Silver CPUs. With the Core i CPUs of the 11 series, it is 14nm. AMD has been using 7nm since the Ryzen 3000 series.
Intel’s 7nm manufacturing process will be called “Intel 4” in the future. The extended process in 7nm + will be called “Intel 3”. The latest 10nm process called “10nm Enhanced Super Fin” is said to be up to 15 percent more efficient than the previous 10nm process – the new name in this case is “Intel 7”, and Intel 7 is also what we see as the first innovation expected later this year.
The CPUs of the Alder Lake and Sapphire Rapids family should be mentioned here as key points. Intel 3 and Intel 4 are to be expected afterwards, i.e. 2022 and 2023, whereby Intel 4 is about Meteor Lake CPUs among other things. In addition, there is also an Intel 20A, which is a glimpse into 2024. Intel wants to establish a 5nm process here. The capital letter A also has a meaning, because it stands for the dimension designation Angstrom: 20 Angstrom is 2nm – although Intel 20A will not start directly with this very small manufacturing process, Intel probably wants to usher in a kind of new technology section with the name.
