Intel Core Ultra 5 245K
Intel's mid-range Arrow Lake-S desktop chip: 14 cores (6P+8E) without Hyper-Threading, a 4.2 GHz base clock and 5.2 GHz boost, on the new LGA1851 socket. Its 159 W turbo ceiling is the lowest of the launch Core Ultra 200S lineup, making it the easiest of the three K-series parts to cool.
Pros
- 14 cores (6P+8E) with a high 4.2 GHz base clock for its tier
- 159 W maximum turbo power is the lowest of the launch Core Ultra 200S lineup, easing cooling demands
- Unlocked multiplier for overclocking
- Native DDR5-6400 support and full PCIe 5.0 connectivity
- 50 MB of combined cache (26 MB L2 + 24 MB L3) for a mid-range part
Cons
- No cooler included
- Requires a new LGA1851 motherboard; no backward compatibility with older Intel boards
- No Hyper-Threading, so its 14 threads can trail previous-generation 14-core/20-thread chips in heavily threaded workloads
- Shares the same 4 Xe-core integrated graphics as the rest of the lineup, adequate only for light gaming and media
Very good
