Intel Core Ultra 5 245KF LGA1851 Desktop Processor (5.2 GHz / 14 Cores / 14 Threads)

The Intel Core Ultra 5 245KF is an unlocked Series 2 (Arrow Lake) desktop processor built for the LGA1851 platform. According to the manufacturer-aligned specifications published by our sources, it pairs 14 cores and 14 threads with a 5.2 GHz maximum turbo frequency and a 3.6 GHz base clock, backed by 24 MB of Intel Smart Cache to keep frequently accessed data close to the execution units. Because the suffix is ‘KF’, the chip ships with an unlocked multiplier for enthusiasts who want to tune voltage and frequency on B860 or Z890 motherboards, but it omits the die integrated graphics – so a discrete graphics card is required to drive a display. Power delivery is rated at 125 W base and 159 W maximum turbo, which sits in the mid-range thermal envelope typical of mainstream unlocked Intel desktop CPUs and pairs well with a capable air or 240 mm-class liquid cooler (not included in the retail box). The memory controller supports up to 256 GB of DDR5 across two channels at speeds up to 6400 MT/s, giving builders meaningful headroom for high-frame-rate gaming, multi-application workloads and lightly threaded creative work such as photo editing, code compilation and 1080p/1440p game streaming. With a 14-core layout but no Hyper-Threading on this part (14 threads total), the 245KF is best read as a focused gaming and everyday-productivity chip rather than a heavily multi-threaded rendering workhorse – shoppers prioritising sustained all-core throughput should compare against the Core Ultra 7 265KF (20 cores) listed in our LGA1851 range.
