Intel Core Ultra 9 285K 24-Core Desktop Processor 5.7 GHz

Name: Intel Core Ultra 9 285K 24-Core Desktop Processor 5.7 GHz
Brand: Intel
SKU: Intel Core Ultra 9 285K

Overview

The Intel Core Ultra 9 285K is a flagship desktop processor built on Intel's Performance Hybrid Architecture, combining 8 high-performance P-cores with 16 efficiency-focused E-cores for a total of 24 cores and 24 threads. This design intelligently distributes workloads — routing demanding tasks like gaming and content creation to the P-cores while offloading background processes to the E-cores — resulting in a processor that delivers top-tier performance while improving overall system efficiency. With a maximum turbo frequency of 5.7 GHz and 40MB of cache, the 285K is engineered for users who demand the fastest possible responsiveness in games, video editing, 3D rendering, and software compilation.

As an unlocked "K" series processor, the Core Ultra 9 285K gives enthusiasts full control over clock speeds for further performance tuning. It supports PCIe 5.0 and 4.0 lanes for cutting-edge GPU and NVMe SSD connectivity, along with DDR5 memory for high-bandwidth data throughput. The processor fits the LGA 1851 socket and requires an Intel 800 series chipset motherboard. With a processor base power of 125W and no included thermal solution, buyers should plan for a capable tower cooler or AIO liquid cooling setup. Intel Turbo Boost Max Technology 3.0, Intel Optane Memory support, and integrated Intel Graphics round out a feature set aimed squarely at the high-end desktop market.

Pros & Cons

👍 Pros

24-core hybrid architecture with 8 P-cores and 16 E-cores handles multithreaded workloads and single-threaded tasks efficiently.
Unlocked multiplier with up to 5.7 GHz boost clock provides headroom for overclocking enthusiasts.
40MB of cache ensures fast data access for demanding gaming and content creation workflows.
PCIe 5.0 and 4.0 support provides high-bandwidth connectivity for the latest GPUs and NVMe storage.
Integrated Intel Graphics included for basic display output without requiring a discrete GPU.

👎 Cons

125W base power draw generates significant heat, requiring a high-end cooling solution not included in the box.
Compatible only with Intel 800 series motherboards on LGA 1851, requiring a platform upgrade from previous Intel generations.
DDR5-only memory support means existing DDR4 RAM cannot be reused from older builds.
24 threads across 24 cores means no simultaneous multithreading on E-cores, potentially limiting some heavily threaded workloads.
Premium pricing positions this processor well above mid-range options.

Frequently Asked Questions

How many cores and threads does the Core Ultra 9 285K have?

The Core Ultra 9 285K has 24 cores — 8 Performance cores (P-cores) and 16 Efficient cores (E-cores) — with 24 threads total.

Does the Core Ultra 9 285K include integrated graphics?

Yes. The processor includes integrated Intel Graphics, so a discrete GPU is not strictly required for basic display output and everyday tasks.

What motherboard chipset is required for the Core Ultra 9 285K?

The Core Ultra 9 285K is compatible with Intel 800 series chipset-based motherboards using the LGA 1851 socket.

Does the Core Ultra 9 285K come with a cooler?

No. No thermal solution is included. A separately purchased CPU cooler capable of handling the 125W base power draw and boost power requirements is necessary.

Is the Core Ultra 9 285K unlocked for overclocking?

Yes. The "K" designation means this processor is fully unlocked, allowing users to overclock beyond its 5.7 GHz maximum turbo frequency with compatible motherboards and cooling.
