Core Ultra 5 245KF

The Core Ultra 5 245KF is a 14-core / 14-thread processor based on the Arrow Lake-S (2024−2025) architecture, manufactured on a 3 nm process node. It reaches a maximum boost clock of 5.2 GHz from a base frequency of 4.2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 24 MB (total) of L3 cache, plus 3 MB (per core) of L2 cache and 192 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 43,424, placing it in the Enthusiast performance tier as a Recent generation product.

The Core Ultra 5 245KF fits into the LGA1851 socket and supports PCIe 5.0 with 20 total PCIe lanes for expansion cards and storage. It supports DDR5-6400 memory at speeds up to 6400 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 192 across 2 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers. Integrated graphics: Intel Graphics (4 Xe-cores) — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

It features an unlocked multiplier, allowing enthusiasts to overclock beyond stock frequencies for additional performance. Virtualization: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Ryzen 5 9600X.

The Core Ultra 5 245KF has a rated TDP (Thermal Design Power) of 125 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately. Recommended cooling: 240mm+ AIO.

At an average price of $189 (MSRP: $294), the Core Ultra 5 245KF delivers 230 PassMark points per dollar. Performance ranking position: #260 out of all indexed processors.
