Something undervalued. Intel changes the socket every generation or two. AMD gives you 5 years and 4 generations.
To be more precise:
Intel changes every 2x CPU Product SKU cycles.
e.g.
LGA1156 = 1st Gen (Nahalem)
LGA1155 = 2nd & 3rd Gen (Sandy Bridge & Ivy Bridge)
LGA1150 = 4th & 5th Gen (Haswell, & Haswell Refresh)
...
LGA1200 = 10th & 11th Gen (Comet Lake & Rocket Lake)
LGA1700 = 12th & 13th Gen (Alder Lake & Raptor Lake)
The last time you got Intel giving you more than 2x generations was:
LGA1151 = 6th, 7th, 8th, 9th Gen ( SkyLake, Kaby Lake, Coffee Lake, Coffee Lake Refresh).
AMD seems to be moving to 3x Zen Generations per Socket.
Socket AM4 = Zen 1, Zen 1+, Zen 2, Zen 3.
Socket AM5 = Zen 4, Zen 5, Zen 6 + (Any Minor refreshes that may occur).
MLiD has interviewed vendors who work at the MoBo companies & Intel.
The big MoBo makers LIKE when Intel sticks to 2x Generations per Socket, gives the MoBo makers something new to make.
AMD is driving Zen along it's own path, that's by design and MoBo makers are accomodating AMD's wishes.
