Core i5-11600K

The Core i5-11600K is a 6-core / 12-thread processor based on the Rocket Lake (2021) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4.9 GHz from a base frequency of 3.9 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 12 MB (total) of L3 cache, plus 256K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 19,520, placing it in the Mid-Range performance tier as a Aging generation product.

The Core i5-11600K fits into the LGA1200 socket and supports PCIe 4.0 with 20 total PCIe lanes for expansion cards and storage. It supports DDR4 memory at speeds up to DDR4-3200 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 128 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: UHD Graphics 750 — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Core i5-11600K is primarily designed for Desktop. It features an unlocked multiplier, allowing enthusiasts to overclock beyond stock frequencies for additional performance. It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads).

The Core i5-11600K has a rated TDP (Thermal Design Power) of 125 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed.

At an average price of $170 (MSRP: $262), the Core i5-11600K delivers 115 PassMark points per dollar. Performance ranking position: #803 out of all indexed processors.
