Community Feedback
What Owners Say
Owners love the sheer multi-threaded grunt for heavy workloads. Common gripes are the high heat output and needing a serious cooler to keep it from throttling.
Pros
- Plows through heavy multitasking without flinching
- Runs surprisingly cool for its performance class
- Quad-channel memory keeps data flowing fast
- Stays relevant for years of demanding work
Cons
- Wasteful power draw for desktop use
- Hot under heavy load
- Dead-end socket with no upgrade path
Verdict
Our verdict on the Core i9-7900X
Intel's i9-7900X is a high-core-count Skylake-X chip that runs hot and demands a pricey motherboard ecosystem.
Get it if you need a ton of CPU cores for heavy workstation tasks like video editing or 3D rendering on an older platform. Skip it if you’re gaming or building new, because cheaper modern chips run faster and cooler.
Buy it if…
- You want to run heavy multi-threaded workstation tasks on an older platform.
- You need a high-core-count CPU for a budget used workstation build.
- You are upgrading a 2017-era high-end desktop and want maximum cores.
