The Intel Core i9-12900KS is a desktop processor built on the Alder Lake architecture and designed for the LGA 1700 socket. This 12th-generation CPU employs a hybrid design consisting of 16 cores, split between eight performance cores and eight efficiency cores, to manage 24 concurrent threads. It operates at a base frequency of 3.4 GHz and reaches a maximum turbo frequency of 5.5 GHz for demanding single-threaded tasks. This model is engineered for high-performance desktop systems requiring substantial computing power for gaming, content creation, or professional software development. The 7 nm lithography ensures efficient data processing across the 30 MB of L3 Smart Cache.
This processor supports dual-channel memory configurations with compatibility for both DDR4 at 3200 MHz and DDR5 at 4800 MHz, allowing for a maximum capacity of 128 GB. It features integrated Intel UHD Graphics 770, which provides video output through HDMI 2.1 and DisplayPort 1.4a protocols when a dedicated graphics card is not installed. System expansion is facilitated through PCIe 4.0 and 5.0 support for high-speed communication with NVMe drives and modern GPUs. The CPU has a base thermal design power of 150 W and arrives in a boxed package that does not include a factory cooling solution.
