01 / 06Intel Core Ultra 9 285K 24-Core LGA 1851 Desktop Processor (Arrow Lake)
The Intel Core Ultra 9 285K is the flagship 24-core Arrow Lake desktop processor for LGA 1851 (Intel 800-series chipset) platforms, pairing 8 Performance-cores with 16 Efficient-cores for maximum multi-threaded throughput alongside elite single-core gaming performance. P-cores boost to 5.7GHz for frame-rate-critical tasks, while 16 E-cores handle background and parallel compute workloads simultaneously. A 125W base TDP with 159W maximum turbo power, 36MB L3 cache, DDR5-6400 or DDR4-3200 dual-channel memory, and Intel Graphics with AI acceleration make the 285K the top choice for high-performance workstations, streaming rigs, and content creation platforms. 3-year warranty.
Features
- 24-Core Hybrid Architecture (8P + 16E) — Eight P-cores deliver elite single-threaded gaming performance while sixteen E-cores maximize multi-threaded throughput for video encoding, 3D rendering, and AI inference.
- 5.7GHz P-Core Turbo Boost — Intel Turbo Boost Max 3.0 pushes the best P-core to 5.7GHz, maintaining sub-millisecond frame times in competitive titles and low-latency audio production.
- 36MB L3 Cache — The largest L3 cache in the Arrow Lake lineup reduces memory access latency for large open-world games, simulation datasets, and enterprise workloads that benefit from on-die data residence.
- 125W PBP / 159W MTP — Flexible TDP configuration lets you run the 285K within a thermal budget — 125W for quiet productivity or 159W for sustained all-core burst performance.
- DDR5-6400 & DDR4-3200 Support — Dual-channel memory controller supports both DDR5 (up to 6400MT/s) and DDR4 (up to 3200MT/s) for compatibility across memory generations.
- Intel Graphics with AI Acceleration — Integrated GPU handles display output and accelerates AI-based tasks (upscaling, media transcode), eliminating the need for a discrete GPU in productivity-only builds.
- LGA 1851 (Intel 800-Series Platform) — Compatible with Z890, B860, and H870 motherboards with PCIe 5.0 x16 GPU slots, PCIe 5.0/4.0 M.2 storage, and Wi-Fi 7 for a full next-gen platform.
