Intel Core Ultra 9 285K is a high-performance desktop processor featuring 24 cores (8 Performance cores + 16 Efficient cores) and 24 threads, built on Intel's Arrow Lake architecture. With a base frequency of 3.7 GHz and boost up to 5.7 GHz, this processor delivers strong multi-threaded performance, achieving Cinebench 2024 scores of 2,500+ points—approximately 14% faster than the Core i9-14900K and 7% faster than AMD Ryzen 9 9950X in productivity workloads. The processor supports DDR5-6400 memory up to 192GB capacity and features 36MB of Smart Cache (L2+L3).
The 285K integrates Intel Graphics with 4 Xe-cores and includes Intel AI Boost NPU capable of 13 TOPS, contributing to a total system performance of 36 TOPS when combined with CPU and GPU capabilities. It supports 20 PCIe 5.0 lanes, enabling 16x for discrete GPUs and 4x for NVMe storage. The processor operates at a base TDP of 125W with maximum turbo power of 250W, representing improved power efficiency compared to previous-generation Intel CPUs. However, gaming performance shows a 5% deficit versus the 14900K and 28% deficit versus AMD's 7800X3D, making it better suited for productivity and content creation workloads.
