AMD‘s AM4 has the 1xxx, 2xxx, 3xxx, and 5xxx series cpus with ddr4 = 5+ yrs. The new AM5 has the 7xxx series with ddr5 = 3+ yrs or more. The AM4 started with 8c/16t cpus and ended with 16c/32t AND has the MOST recommended gaming cpu the 5800x3d. < I would recommend reading a review on this cpu
. AMD has released the 7800x3d for the AM5 and has plans to release several more x3d cpus for it BUT this also requires ddr5. ** IIRC the new RTX-4xxx requires the new 16 pin gpu power connector > WHICH < also requirese a new psu
Intel is currently running the z6xx/z7xx chipsets (LGA-1700) that has the 12xxx, 13xxx and yet to be released 14xxx series cpus. These can be run with ddr4 or ddr5 mb dependent. Intel is on the 2 CPUs per chipset so after 2023 they will have a new cpu/chipset released around Q2 2024
