Intel Core Ultra 5 250KF Plus Desktop Processor: 18-Core Unlocked Performance for Dedicated GPU Gaming PCs
The Intel Core Ultra 5 250KF Plus combines 18-core Arrow Lake performance with an unlocked design for enthusiasts building PCs with a dedicated graphics card. With 18 cores, boost speeds of up to 5.3 GHz, Intel AI Boost, PCIe 5.0, and fast DDR5-7200 memory support, it provides a powerful foundation for gaming, streaming, content creation, and demanding desktop workloads.
The key difference is the “F” designation: the Core Ultra 5 250KF Plus does not include integrated graphics, so a dedicated graphics card is required. Combined with its unlocked multiplier, this makes it particularly well suited to enthusiast gaming PCs where a discrete GPU handles graphics and display output.
Built on Intel’s Arrow Lake architecture, the processor combines 6 Performance-cores and 12 Efficient-cores to provide substantial processing capacity for demanding applications and heavy multitasking. The unlocked design also gives experienced users the flexibility to tune processor performance on compatible motherboards.
