About the Intel Core i7-8700K CPU
The Intel Core i7-8700K is an end-of-life 6-core (12-thread) processor built for the desktop CPU market. It launched in Q4 2017 with a suggested retail price of $359. It is part of Intel's Core i7 lineup, which is based on the Coffee Lake microarchitecture. The i7-8700K is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD Graphics 630 integrated graphics solution.
Memory and Cache
The Core i7-8700K supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-8700K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 12 MB.
Cores and Clock Speeds
The Core i7-8700K features 6 total cores which can process 12 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.7 GHz, and it can boost up to 4.7 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.
Integrated Graphics
The Core i7-8700K includes an integrated graphics solution called UHD Graphics 630. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card.
