If and when you buy a computer with multiple cores, I encourage you to buy one where all the cores are the same. BTW: in both Arm and Intel, the lowest end multi-core CPU PCs use a single socket solution, so you have absolutely no option of having different architectures on that single socket. Greg (not KH)
