Green marks the stronger figure for that row only — for power draw and PSU requirement, lower is treated as better. Performance indexes are CanMyPcPlay estimates; read how they are derived.
Which should you pick?
- Games follow single-thread. For gaming, the single-thread index matters more than core count.
- Creative work follows multi-thread. Rendering, compiling and encoding scale with cores.
- Sockets differ. Moving between platforms usually means a new motherboard and often new memory.
