According to TechPowerUp, Intel has discontinued several 11th-generation Core mobile processors: including i5-11400H / i7-11800H.
As shown above, in the Intel Product Change Notice (PCN), Intel lists five 11-generation Core H-series processors and four 11-generation Core B-series processors (for Intel NUC 11 Extreme hosts) built on the H-series. Intel will stop letting customers order these parts from the end of June this year, with the last shipment being at the end of January 2024.
Intel’s 11th generation Core H-series processors use a 10 nm SuperFin process with up to 8 cores and 16 threads and no small cores. Currently, Intel has launched the 12th and 13th generation Core H series processors, both using the Intel 7 process, with new small cores, up to 8 large cores + 16 small cores.
