Modern Hybrid Performance for Gaming and Multitasking
The Core Ultra 5 245KF is designed to deliver strong desktop performance across a wide range of real workloads. Its 6 Performance-cores handle latency-sensitive tasks such as gaming, demanding foreground applications and heavy single-threaded workloads, while the 8 Efficient-cores help with background processes, multitasking and parallel workloads. This hybrid design makes the processor well suited to gaming systems, creator desktops and enthusiast PCs that need both quick responsiveness and strong sustained throughput.
Built for New-Generation DDR5 and PCIe 5.0 Platforms
With support for DDR5 memory up to 6400 MT/s and PCI Express 5.0, the 245KF is aimed at modern desktop builds that prioritize bandwidth, expansion flexibility and long-term platform relevance. It fits the LGA1851 socket and supports up to 24 PCIe lanes, giving system builders more flexibility for fast graphics cards and high-speed storage. This makes it a strong match for users assembling a fresh enthusiast desktop rather than upgrading older mainstream platforms.
Unlocked KF Model for Dedicated-GPU Builds
As a KF-series processor, the Core Ultra 5 245KF is intended for systems that use a dedicated graphics card. It does not include integrated graphics, so it should be paired with a discrete GPU from the start. In return, users get an unlocked multiplier processor aimed at performance-focused desktop builds. It also includes Intel AI Boost NPU capability for supported AI-enhanced workloads, adding another layer of modern functionality to the platform.
BUYER'S GUIDE
For who
Gamers, enthusiasts and advanced desktop builders who want a modern unlocked Intel processor for a dedicated-GPU system with strong hybrid-core performance and next-generation platform support.
The real reason to buy it
It combines 14-core hybrid performance, up to 5.20GHz boost, DDR5 and PCIe 5.0 support, plus an unlocked KF design that targets serious desktop builds with discrete graphics.
Know before you buy
This processor has no integrated graphics, so a dedicated graphics card is required. It is designed for the LGA1851 platform and DDR5 memory, and as an unlocked model it is best paired with a compatible motherboard and cooling setup for performance-focused systems.
