When going for a device, I mostly go for higher and better processors, I use a minimum of octal cores across devices, both phone and PC. Processor and dedicated graphics memory should be the main focus for those coming into tech or related fields (people for photography can get cameras).I can consider RAM too alongside processor for mobile device since it's RAM isn't easily upgradeable, but I don't base preference on RAMs when I'm getting a PC, reason being that RAMs can be upgraded easily for computers. I recently bought a PC which had octal cores with 8gb RAM and manually upgraded it to 24GB to increase it's performance.
