Community Feedback
What Owners Say
Owners like the strong single-core speed for gaming. The usual gripe is it runs hot and needs a pricey motherboard for what is basically a quad-core.
Pros
- Gets you into the enthusiast platform cheap
- Sips power for a high-end socket
- Runs single-threaded apps with real zip
- Plays older games without breaking a sweat
Cons
- No integrated graphics support
- Requires expensive X299 motherboard
- Poor multi-threading for the price
Verdict
Our verdict on the Core i5-7640X
A quad-core Kaby Lake-X chip for the LGA2066 platform that runs hot and offers little over a standard Core i5.
Get it if you need a cheap entry into the X299 platform and don't care about losing multitasking performance. Skip it if you want more than four cores or any modern features like hyperthreading.
Buy it if…
- You want a basic desktop for office work and web browsing.
- You need a cheap entry point to the X299 platform.
- You are replacing a dead LGA2066 chip on a tight budget.
