They could already make them 4-core. 2-core CPUs are not even enough for office work when you use multiple applications. I saw weird options like 2 P-cores and 8 E-cores, but they are probably not available on the mass market. Something like 2 cores with HT + 4 E-cores could be already good.
Btw. I didn't know Patriot makes DDR5 with Samsung IC.
