Intel Core i9 11900K Review
Overview The Intel Core i9 11900K is a high-end desktop CPU based on the Rocket Lake architecture. It offers 8 cores and 16 threads, clocked at 3.5 GHz to 5.3 GHz with Turbo Boost 3.0 and Adaptive Boost technologies. This processor is designed for enthusiasts and professionals who require high performance in tasks such as content creation, gaming, and professional workloads.
Performance The Intel Core i9 11900K performs impressively in multi-threaded workloads, competing with AMD's Ryzen 7 5800X3D. It can reach up to 4.8 GHz when all cores are utilized and up to 5.1 GHz with a single thread using Turbo Boost 2.0. The processor also supports PCIe 4.0 and Intel DL Boost for AI acceleration, making it suitable for demanding tasks.
Power Consumption The CPU has a TDP of 125W, which can be reduced to 95W if necessary. However, its actual power consumption can be much higher due to its high performance capabilities and the older 14nm manufacturing process, which results in lower-than-average energy efficiency.
