Featured PC
Raptor™ Z55
Our all time most popular, designed for mid-range gaming and other high demand applications. Featuring the all new Intel® i9-12900KS processor.
Configure now1 Max Turbo Frequency is the maximum single-core frequency at which the processor is capable of operating using Intel® Turbo Boost Technology and, if present, Intel® Turbo Boost Max Technology 3.0 and Intel® Thermal Velocity Boost. Intel® Thermal Velocity Boost (Intel® TVB) is a feature that opportunistically and automatically increases clock frequency above single-core and multi-core Intel® Turbo Boost Technology frequencies based on how much the processor is operating below its maximum temperature and whether turbo power budget is available. The frequency gain and duration is dependent on the workload, capabilities of the processor and the processor cooling solution. For more details on Core i9 12900KS specifications, refer to ark.intel.com Intel® Core™ i9-12900KS is a special edition of Intel® Core™ i9-12900K, with even better frequencies.
2 On performance cores. Performance varies by use, configuration and other factors. Learn more at www.Intel.com/PerformanceIndex.
3 Unlocked features are present with select chipsets and processor combinations. Altering clock frequency or voltage may void any product warranties and reduce stability, security, performance, and life of the processor and other components. Check with system and component manufacturers for details.
4 Not available on certain 12th Gen Intel® Core™ processors. Performance hybrid architecture combines two new core microarchitectures, Performance-cores (P-cores) and Efficient-cores (E-cores), on a single processor die. Select 12th Gen Intel® Core™ processors (certain 12th Gen Intel® Core™ i5 processors and lower) do not support performance hybrid architecture, only P-cores.
5 On select SKUs only; requires OS enablement. Built into the hardware, Intel® Thread Director is provided only in performance hybrid architecture configurations of 12th Gen Intel® Core™ processors; OS enablement is required. Available features and functionality vary by OS.
