Intel Core Ultra 5 245KF
The KF variant is a 14-core LGA1851 chip boosting to 5.2GHz at 125W with no integrated graphics. It is the most affordable unlocked Arrow Lake route for builders who already own a discrete GPU. That same KF designation makes it unsuitable for any build that needs onboard graphics, so a GPU is mandatory.

Standards
Form factors & standards — interchangeable across compatible builds, not a platform lock-in.
Compatibility
Built around DDR5, Intel LGA1851. Make sure the rest of your build uses the same platform before you buy — mismatched sockets, mounts or standards are the most common return reason. Check it in the builder →
Upgrade path
Outgrow it and the Intel Core Ultra 9 285K is the natural next step up in cpus. See it →
