While Meteor Lake is likely to be the only product ever made with "Intel 4", the improved variant of "Intel 4" rebranded as "Intel 3" is expected to be launched later in this year in several kinds of server CPUs, i.e. Sierra Forrest, Granite Rapids and Granite Rapids D.
Moreover, "Intel 3" will also be used for some I/O or cache memory tiles even in some later Intel CPUs where the computing tiles will be made with denser processes like "Intel 18A".
For now, Meteor Lake with "Intel 4" is the first Intel product made with a process that has been developed after the change of CEO. It remains to be seen later this year, based on whether the planned server CPUs will be launched successfully, then by the end of the year also the first CPUs with big cores having the first new microarchitecture since 2021 (Arrow Lake, Arrow Lake S and Lunar Lake), if Pat Gelsinger has succeeded to restore Intel's competitivity.
