The Intel Core Ultra 9 285K is a high-performance desktop processor from Intel's Core Ultra Series 2, designed for demanding gaming, content creation, productivity and advanced desktop workloads. Based on Intel's Arrow Lake architecture, it combines 24 cores and 24 threads, consisting of 8 Performance-cores and 16 Efficient-cores. The processor can reach a maximum turbo frequency of 5.7 GHz, with a P-core maximum turbo frequency of 5.5 GHz and E-core maximum turbo frequency of 4.6 GHz. It features 36MB of Intel Smart Cache alongside 40MB of total L2 cache, providing substantial cache resources for demanding applications. With a 125W Processor Base Power and up to 250W Maximum Turbo Power, the 285K is designed for high-performance desktop systems.

24-Core Hybrid Architecture

The Core Ultra 9 285K uses Intel's hybrid processor architecture with 8 Performance-cores and 16 Efficient-cores, delivering a total of 24 cores and 24 threads. The Performance-cores are designed for demanding workloads requiring high individual core performance, while the Efficient-cores provide additional processing capacity for multi-threaded workloads. The processor's P-cores operate at a base frequency of 3.7 GHz and can reach up to 5.5 GHz, while the E-cores have a 3.2 GHz base frequency and can reach up to 4.6 GHz. Intel also specifies a maximum turbo frequency of 5.7 GHz through Thermal Velocity Boost, alongside support for Intel Turbo Boost Max Technology 3.0. This combination gives the processor a broad operating range for gaming, creative applications, software development and other demanding desktop workloads.

Large Cache and High-Speed Processing

The processor features 36MB of Intel Smart Cache and 40MB of total L2 cache, providing a substantial amount of fast on-chip memory for frequently accessed data and instructions. The Core Ultra 9 285K is manufactured using a TSMC N3B process for its compute technology and incorporates Intel's Arrow Lake desktop architecture. Its combination of high clock frequencies, 24 cores and extensive cache is designed to handle workloads ranging from modern games to demanding professional applications. The processor supports Intel technologies including Thread Director, Turbo Boost 2.0, Turbo Boost Max Technology 3.0 and Thermal Velocity Boost, helping the system manage available processing resources according to workload requirements. The 285K is also an unlocked processor, providing additional configuration flexibility for compatible systems and users interested in performance tuning.

DDR5 and PCIe 5.0 Connectivity

The Core Ultra 9 285K supports modern desktop platform connectivity through DDR5 memory and PCIe 5.0 and PCIe 4.0. Intel specifies support for memory speeds of up to DDR5-6400 MT/s, with two memory channels and support for up to 256GB of memory according to the current processor specification. The CPU provides up to 24 PCIe lanes, with supported configurations including combinations such as 1×16 plus 2×4 or 2×8 plus 2×4. This provides high-speed connectivity for compatible graphics cards, NVMe storage and other PCIe devices. The processor uses the FCLGA1851 socket and is designed for Intel 800 Series desktop platforms. Intel also specifies DMI 4.0 connectivity with up to eight DMI lanes, providing high-speed communication between the processor and compatible chipset.

Integrated Intel Graphics and AI Features

Unlike Intel's KF processors, the Core Ultra 9 285K includes integrated Intel Graphics with four Xe-cores and a maximum dynamic graphics frequency of 2.0 GHz. The integrated graphics support modern display technologies including DisplayPort 2.1 UHBR20 and HDMI 2.1 FRL, while hardware acceleration is provided for H.264, H.265 and AV1 encoding and decoding. The processor also includes an Intel AI Boost NPU with up to 13 TOPS of AI performance, while the CPU and integrated GPU contribute to the processor's broader AI capabilities. Intel specifies an overall peak of 36 TOPS. Additional technologies include Intel Deep Learning Boost, OpenVINO support and Intel Quick Sync Video. These features provide the 285K with integrated capabilities for AI-enabled applications, media processing and compatible workloads without requiring a discrete graphics card for basic display functionality.

Unlocked Tray Processor for High-End Builds

The Intel Core Ultra 9 285K Tray is an unlocked processor designed for high-performance custom desktop systems using the LGA1851 socket and Intel 800 Series chipsets. With 24 cores, 24 threads, up to 5.7 GHz turbo frequency, 36MB Smart Cache and 40MB L2 cache, it provides a substantial processing platform for gaming, workstation applications, content creation and demanding multi-threaded workloads. Its 125W Processor Base Power and up to 250W Maximum Turbo Power mean that an appropriate CPU cooling solution is required when building a system around the processor. The tray version is supplied as a TRAY processor rather than a standard boxed retail package, making it particularly suitable for PC builders and system integrators. Intel's official ordering information confirms dedicated tray versions of the Core Ultra 9 285K.
