Intel Core Ultra 9 285K processor is a desktop processor from the Intel Core Ultra Processors (Series 2) family, identified by manufacturer part number BX80768285K. It combines 24 CPU cores, 24 threads, a boost frequency up to 5.7 GHz, FCLGA1851 platform support and DDR5 up to 6400 MT/s memory support. The specifications on this page are structured for accurate product identification, system planning and business procurement rather than generic processor-family matching.

Product Overview

The processor is built around Arrow Lake desktop hybrid architecture. Its core configuration is 8 Performance-cores + 16 Efficient-cores, providing 24 physical CPU cores and 24 processing threads. The design is intended for desktop computing where workload requirements may include gaming, content creation, compilation, productivity, multitasking, software development and business applications. The exact balance of single-threaded and multi-threaded performance depends on the application, operating system, memory configuration, cooling solution and platform firmware. For procurement teams, Intel Core Ultra 9 285K processor should be matched by its full model name and MPN rather than by family name alone.

CPU Architecture, Core Count and Threading

At the processor level, Intel Core Ultra 9 285K processor provides 24 cores and 24 threads. 8 Performance-cores + 16 Efficient-cores describes the manufacturer-defined core arrangement used by this SKU. Core count and thread count are important when estimating how a workstation or desktop may handle simultaneous applications, background tasks, rendering, code compilation, virtualized development tasks and other parallel workloads. Software behaviour varies by application, so core count should be evaluated together with clock frequency, cache, memory bandwidth and the specific software stack.

The processor is unlocked for supported tuning and overclocking workflows, subject to motherboard, cooling, power and warranty considerations. This distinction is relevant to system integrators because tuning capability does not remove the need for a stable motherboard power design, current BIOS, appropriate thermal headroom and validated memory. Commercial systems should normally prioritize repeatable stability and documented configuration over aggressive manual tuning.

Clock Frequency and Cache

The verified maximum boost frequency is up to 5.7 GHz. Boost behaviour is dynamic and depends on workload, temperature, electrical limits, motherboard firmware and available power. The processor provides 36 MB Intel Smart Cache together with 40 MB L2 cache. Cache capacity helps keep frequently accessed data closer to the CPU cores and can affect responsiveness in latency-sensitive or data-intensive workloads.

For sustained workloads, Intel Core Ultra 9 285K processor should be configured with cooling and chassis airflow appropriate to its verified power specification of 125 W processor base power; 250 W maximum turbo power. Power figures describe processor operating limits or design targets, not total system wall consumption. The complete PC power requirement also depends on graphics, storage, motherboard, fans, USB devices and other installed hardware.

Memory and Desktop Platform

This processor uses the LGA1851 desktop platform and should be paired with a compatible Intel 800-series motherboard whose BIOS supports the exact processor model. The platform uses DDR5 memory only. Builders should verify motherboard CPU support, BIOS revision, DIMM compatibility, CPU cooler mounting, chassis clearance and power-delivery capability before deployment.

Memory support for this SKU is listed as DDR5 up to 6400 MT/s, with a supported capacity of up to 256 GB. Actual memory speed can depend on DIMM count, rank configuration, motherboard topology, BIOS, memory kit and processor memory controller behaviour. For business or repeat system builds, validated memory kits are preferable because they make the configuration easier to reproduce across multiple units.

PCI Express and Expansion Planning

The processor platform supports PCIe 5.0 and 4.0, up to 24 lanes. PCI Express capability helps define the connection between the processor platform and high-bandwidth devices such as graphics cards and NVMe storage. The exact lane routing available to an installed device is determined by the motherboard design and chipset, so builders should review the board manual when using multiple PCIe cards, multiple M.2 drives or other devices that can share lanes or bandwidth.

Graphics and Platform Acceleration

The processor includes Intel Graphics with 4 Xe-cores. This can provide display and media functionality on a compatible motherboard without requiring a discrete graphics card for basic display output. It also includes Intel AI Boost NPU, 13 TOPS, giving the platform a dedicated on-chip AI acceleration resource for supported software. A discrete GPU can still be installed when the workload requires substantially greater graphics performance.

Power, Cooling and Installation Considerations

When configuring Intel Core Ultra 9 285K processor, cooling should be selected for the intended sustained workload rather than only for short benchmark behaviour. Cooler capacity, mounting pressure, thermal interface material, case ventilation and ambient temperature all influence operating temperature. The motherboard should provide the correct socket, BIOS support and power-delivery capability for the processor. For high-power systems, PSU capacity should be selected from the requirements of the complete build, especially the discrete graphics card, rather than from CPU power alone.

Installation should be performed using normal ESD precautions and the motherboard manufacturer procedure. Confirm socket orientation before seating the CPU, avoid touching contact surfaces, apply or use thermal material according to the cooler instructions, and connect required CPU power headers. After assembly, update firmware only through the motherboard vendor’s supported method and verify memory, storage, fan control and operating-system drivers before placing the system into production.

Workload Fit and Use Cases

The Intel Core Ultra 9 285K processor can be specified for desktop systems where its verified core count, clock range, memory platform and expansion capabilities fit the workload. Typical deployments can include gaming PCs with an appropriate GPU, creator systems, software-development machines, productivity desktops, engineering or design workstations and business systems that need a clearly defined processor platform. No single processor specification determines application performance, so final selection should consider the complete system and the software that will run on it.

For gaming-focused systems, CPU selection should be balanced with the graphics card, target resolution and refresh rate. For creator or productivity systems, core count, memory capacity, storage performance and accelerator support may have greater importance. For business deployments, motherboard availability, memory validation, thermal consistency and the ability to source the same MPN repeatedly can be as important as peak benchmark results.
