I will wait until the have AMD efficient chip for one very simple reason: AMD graciously allow ECC on some* cpus.
*well, they allowed on all CPUs, but after zen3 they saw how much money intel was making and joined in. now you must get a "PRO" cpu, to get ECC support, even on mobile (but good luck finding ECC sodimm).
And good luck finding a single fucking computer for sale that even uses these "Pro" CPUs, because they sure as hell don't sell them to the likes of Minisforum and Beelink.
There was some stuff in DDR5 that made ECC harder to implement (unlike DDR4 where pretty much everything AMD made supported unbuffered ECC by default), but its still ridiculous how hard it is to find something that supports DDR5 ECC that doesn't suck down 500W at idle.
