Core Ultra 9 275HX

The Core Ultra 9 275HX is a 24-core / 24-thread processor based on the Arrow Lake-HX (2025) architecture, manufactured on a 3 nm process node. It reaches a maximum boost clock of 5.4 GHz from a base frequency of 2.7 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 36 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 56,018, placing it in the Enthusiast performance tier as a Current Gen generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,835, while multi-core reaches 17,908.

The Core Ultra 9 275HX fits into the FCBGA2114 socket and supports PCIe 5.0 with 24 total PCIe lanes for expansion cards and storage. It supports DDR5-6400 memory at speeds up to DDR5-6400 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 256 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: Intel Arc Graphics — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Core Ultra 9 275HX is primarily designed for High-End Gaming Laptop. 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 9 9955HX.

The Core Ultra 9 275HX has a rated TDP (Thermal Design Power) of 55 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: High Performance Laptop Cooling.

Performance ranking position: #162 out of all indexed processors.
