Intel Core Ultra 5 245KF
Intel's mid-range unlocked Arrow Lake-S chip with no integrated graphics: 14 cores (6P+8E) reaching 5.2 GHz on the LGA1851 socket. Aimed at buyers who already own a discrete GPU, it trades the onboard display output of the Core Ultra 5 245K for a lower price on otherwise identical silicon.
Pros
- 6 Performance-cores turbo to 5.2 GHz with an unlocked multiplier for tuning
- DDR5-6400 memory support with PCIe 5.0 and 24 CPU-side lanes
- 26 MB of combined L2 cache aids latency-sensitive workloads
- Priced below the otherwise identical Core Ultra 5 245K since it ships without an iGPU
- 125 W base power keeps it manageable for mid-tower air cooling under typical loads
Cons
- No integrated graphics, so a faulty discrete card leaves no fallback display output
- Needs a new LGA1851 motherboard; nothing from the LGA1700 generation fits
- 159 W maximum turbo power still needs more than a stock-tier cooler to sustain boost clocks
- No Hyper-Threading, so its 14 threads map one-to-one to 14 physical cores
Very good
