Community Feedback
What Owners Say
Owners love the raw multi-threading power for heavy work, but the high heat output and price tag for an older socket leave them feeling it's a tough sell.
Pros
- Heavy multi-threaded work flies
- Stays cool with big air coolers
- Plenty of PCIe lanes for add-ons
- Still fast enough for everyday gaming
Cons
- Hot and power hungry
- No real overclocking headroom
- Outdated platform with no upgrade path
Verdict
Our verdict on the Core i7-9800X
The i7-9800X is Intel's late-2018 HEDT chip that feels like a cut-down server part, its main caveat being pricey platform costs for what you get.
Get it if you need lots of PCIe lanes for multi-GPU setups or heavy storage arrays on a workstation. Skip it if you don't use all those lanes, since newer mainstream chips run faster and cooler for less cash.
Buy it if…
- You need heaps of PCIe lanes for multiple fast SSDs or GPUs.
- You run heavily threaded workstation apps like video rendering or 3D modeling.
- You're building a dual-GPU gaming rig on an older X299 platform.
