Please give suggestion for below 4k laptop.

Must have ssd and dual channel 8gb ram! No AMD!

First of all, there's no such thing as "dual-channel memory." Memory channeling exists at the platform level, so a dual-channel chipset or IMC (Integrated Memory Controller, as in modern CPUs) may exist, but the memory itself does not have a special bit or chip that controls this. It is up to the motherboard and supporting platform to offer multiple channels.
