Intel Core Ultra 9 285K 3.7GHz 5.7GHz

Intel Intel BX80768285K | 24-Core Arrow-Lake Desktop Processor

The Intel Core Ultra 9 285K (3.7 GHz / 5.7 GHz) targets demanding UK desktop users. This processor suits gamers, streamers, and content creators who need high multi-threaded performance. It features a new architecture with dedicated AI acceleration capabilities.

Intel Core Ultra 9 285K (3.7 GHz / 5.7 GHz)

This processor uses the Intel Arrow-Lake-S platform. It provides 24 cores and 24 threads for complex workloads. The CPU operates at a base frequency of 3.7 GHz, reaching up to 5.7 GHz in turbo mode. It supports DDR5 memory via a dual-channel controller.

AI-Ready Performance for Modern Workloads

The processor includes a Neural Processing Unit (NPU). This unit handles AI tasks locally. It manages background suppression, audio optimisation, and automatic framing. This frees up the main cores for gaming and rendering.

Because the NPU handles these tasks, your system remains responsive. You get smoother streaming without impacting game frame rates. This architecture is designed for mixed-use scenarios.

High-Speed Memory and Cache Support

This CPU supports DDR5 memory. The official specification lists DDR5 6400 MHz as the supported frequency. It uses a dual-channel controller for increased bandwidth. This helps in data-intensive tasks like video editing.

It also features a large 36 MB L3 cache. The L2 cache is 40 MB. Large caches reduce latency. This improves performance in gaming and application loading.

Unlocked for Overclocking

The Intel Core Ultra 9 285K is unlocked. This means the multiplier is adjustable for overclocking. Enthusiasts can push the frequency beyond the standard 5.7 GHz turbo.

However, overclocking requires specific hardware. You must use a compatible motherboard. Ensure you have adequate cooling. The CPU fan is not supplied with this box version.

Integrated Graphics and Connectivity

This processor includes an integrated Intel Graphics controller. It supports basic display output without a discrete GPU. This is useful for troubleshooting or office builds.

It supports PCI-E 5.0. This ensures compatibility with the latest storage and graphics cards. However, you must verify the motherboard chipset supports PCI-E 5.0. The CPU itself is compatible with Intel Z890, B860, and H810 chipsets.
