Frequently Asked Questions
What motherboard do I need for the Intel Core Ultra 5 245KF?
The Intel Core Ultra 5 245KF requires a motherboard with the LGA1851 socket, which means you need an Intel 800-series chipset motherboard such as Z890 or B860. These boards support DDR5 memory and PCIe 5.0, ensuring you can take full advantage of the processor's capabilities.
Does the Intel Core Ultra 5 245KF come with a cooler?
No, this processor does not include a cooler in the box. You must purchase a separate CPU cooler capable of handling at least 125W TDP, with 159W recommended if you plan to run sustained heavy workloads or overclocking. Most tower air coolers and 240mm or larger AIO liquid coolers will work well.
Do I need a graphics card with the Intel Core Ultra 5 245KF?
Yes, absolutely. The KF designation means this processor has no integrated graphics, so you must install a discrete graphics card to get any video output. This makes the 245KF ideal for gaming builds where you are already planning to use a dedicated GPU.

Description
The Intel Core Ultra 5 245KF is a high-performance desktop processor designed for gamers and content creators who demand both power and AI capability. Built on Intel's latest Core Ultra architecture, this unlocked 14-core chip delivers exceptional responsiveness for gaming, streaming, and creative workloads. With integrated AI acceleration through Intel AI Boost NPU, the 245KF brings hardware-accelerated machine learning to desktop PCs for the first time. Under the hood, you get 6 Performance cores running up to 5.2GHz paired with 8 Efficient cores reaching 4.6GHz, supported by 24MB of cache. With 20 threads working in parallel, this processor handles demanding multi-threaded tasks whilst maintaining smooth gaming performance. The KF designation means there is no integrated graphics, so you must pair this chip with a discrete graphics card. The unlocked multiplier allows enthusiasts to push clock speeds beyond stock for even greater performance. This processor uses the new LGA1851 socket and requires a compatible 800-series motherboard with DDR5 memory support. No cooler is included in the box, so you will need to purchase a separate CPU cooler rated for at least 125W TDP. The retail boxed version comes with Intel's standard warranty. For builders planning a dedicated gaming or workstation PC with a discrete GPU, the 245KF offers cutting-edge performance with AI features that accelerate everything from video editing to content creation tools.Feature
