About the Intel Core i9-14900K CPU
The Intel Core i9-14900K is a 24-core (32-thread) processor built for the desktop CPU market. It launched in Q4 2023 with a suggested retail price of $589. It is part of Intel's Core i9 lineup, which is based on the Raptor Lake Refresh microarchitecture. The i9-14900K is compatible with Intel Socket 1700 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 770 integrated graphics solution.
Memory and Cache
The Core i9-14900K supports DDR4-3200, DDR5-5600 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i9-14900K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 36 MB.
Cores and Clock Speeds
The Core i9-14900K features 24 total cores which can process 32 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel.
