How to choose processors (cpus)
Gaming vs productivity
For gaming, cache size and per-core speed matter most, which is why AMD's X3D chips dominate. For video editing, rendering and compiling, more cores win.
Platform matters
AMD's AM5 socket is expected to be supported for several more years, which makes future upgrades easy. Check motherboard compatibility before buying.
Budget for cooling
Many CPUs don't include a cooler. A good tower air cooler is enough for all but the hottest chips.
DDR5 only
Current AMD AM5 and Intel LGA 1851 platforms use DDR5 memory exclusively, so factor that into your budget.
