The newest workstation CPUs released by Intel this month are the Sapphire Rapid Refresh, which use the Golden Cove Core, when Raptor Cove, Redwood Cove and Lion Cove are already released on products, meaning Sapphire rapids Refresh uses 3 generation old core architectures (2, if you do not count raptor cove because it is very similar to golden cove)
By comparison, AMD’s Threadrippers released with ZEN 4, which at the time was the latest Core (though closer to zen 5 release than zen 4 release)
consumer market wants new stuff every year, enterprise wants stuff every 5 years. AMD was selling Zen3 (TR and EPYC) when Zen4 was long available for desktop. AMD even milked the heck out of Zen2 Threadripper because Intel didn’t have any competing product
While it is true that some enterprise customers really value stability and buy older well tested hardware (while enterprise customers need the performance and buy newer hardware)
This is a workstation product, not extreme high reliability server product
And if some customers want an old workstation product they can still get it, for example you can still buy zen 3 threadripper
