Buying Guide: What to Look For
Cores vs Clock Speed
For gaming and productivity, decide whether your work scales with cores (rendering, encoding favor 16-24) or single-thread speed (responsiveness, many apps). The best chip balances both for your software.
Platform and Memory
AM5 and modern Intel platforms support DDR5 and ample PCIe lanes; AM4 reuses cheaper DDR4 for budgets. Factor the whole platform cost when comparing chips.
Cooling
High-core chips under sustained load need a 280-360mm AIO; efficient 8-core X3D chips run cool on quality air coolers. Match cooling to the chip and workload.
