Key takeaways
- Core and thread count: Six cores handle gaming well, but eight or more help with streaming and heavy multitasking. Match the count to your workload.
- Gaming vs. productivity: Newer chips with strong single-core speed excel at gaming, while higher-core models suit rendering and content creation.
- Platform and socket: AM5 chips use DDR5 and offer a longer upgrade path, while AM4 remains a great budget value with cheaper boards and memory.
- Included cooler: Some budget chips ship with a stock cooler, saving money. Higher-performance models often require a separate cooler.
- Upgrade longevity: Buying into a newer socket like AM5 means easier future CPU upgrades without replacing your motherboard.
