The short version
The Core Ultra 5 245K has 14 cores (6 P plus 8 E), 24 MB of cache and DDR5-6400 support on socket LGA1851. It keeps integrated Xe graphics and Quick Sync. Launch reviewers found its gaming performance underwhelming against the previous generation. It has since fallen sharply in price, but the newer 250K Plus offers more cores for similar money.
Pros
- 159 W maximum turbo power keeps cooling simple
- Good multithreaded performance for the core count
- PCIe 5.0 and DDR5-6400 support
Cons
- Gaming performance disappointed at launch versus previous-generation Core i5 chips
- The 250K Plus offers more cores for similar money
- LGA1851 is reported to be a dead-end socket
Best for
- Mid-range productivity builds on a new platform
- Buyers who find it heavily discounted

Compatibility notes
- Socket LGA1851 needs an Intel 800-series chipset board (Z890, B860, H810); it is not compatible with LGA1700 boards. Intel notes LGA1700 and LGA1851 coolers are mechanically similar but pin layouts differ.
- DDR5 only, up to 6400 MT/s per Intel's spec page.
- Needs a separate cooler rated for 125 W base power.

Common questions
Which motherboards work with the Core Ultra 5 245K?
It uses socket LGA1851 and needs an Intel 800-series chipset board. LGA1700 boards from the previous two generations will not fit.
What memory does the Core Ultra 5 245K support?
Intel lists DDR5 only, up to 6400 MT/s across two channels and up to 256 GB. It does not support DDR4, so it needs a DDR5 LGA1851 board.
Should I buy the 245K or the 250K Plus?
The 250K Plus has 18 cores and DDR5-7200 support and is rated well by Tom's Hardware. Pick the 245K only when it is clearly cheaper.
