Core i7-8700K Details

Ranking #251 of 2060 in overall performance, the Intel Core i7-8700K delivers a solid blend of single-core and multi-core capabilities, though it's now a product of the past. Launched in October 2017, this Coffee Lake S processor is part of Intel's mainstream desktop lineup, designed for high-performance computing and gaming. While the processor is over six years old as of early 2026, its unlocked multiplier and robust single-core performance still make it relevant for enthusiasts who value overclocking flexibility and high clock speeds. The Core i7-8700K features six cores and twelve threads, enabled by Intel Hyper-Threading, which allows it to handle demanding multitasking and parallel workloads effectively.

Operating at a base frequency of 3.7 GHz, the i7-8700K can boost up to 4.7 GHz on a single core, making it one of the faster desktop processors in its generation. It is built on Intel’s 14 nm process, with a TDP of 95 W, requiring adequate cooling to maintain peak performance under sustained loads. The chip supports DDR4-2666 memory in a dual-channel configuration, with a maximum capacity of 64 GB. It also features a 12 MB L3 cache, 1.5 MB of L2 cache, and 0.375 MB of L1 cache, ensuring low-latency access to frequently used data.

The integrated UHD Graphics 630 GPU, with 24 execution units and a base frequency of 350 MHz, offers basic graphics performance suitable for office applications and light multimedia playback but lacks the power for modern gaming. Despite its age, the processor supports a wide range of modern technologies, including AVX, AVX2, AES-NI, and Intel’s Turbo Boost 2.0, which dynamically increase clock speeds based on workload and thermal headroom. It also includes features like Intel vPro, VT-x, and VT-d for virtualization, as well as secure boot and trusted execution technologies.

In benchmark testing, the Core i7-8700K earns a Singlecore Score of 6302, placing it at #178 among 2060 processors—significantly faster than many modern mainstream CPUs. Its Multicore Score of 5544 ranks it at #380, while its Overall Score of 5999 positions it at #251. This indicates that while its single-core performance remains competitive, its multi-core capabilities are now outpaced by newer architectures, particularly in the mid-range and high-end segments. In comparison, it is slightly slower than the Ryzen 5 5600X and Ryzen 9 6900HS, but still outperforms many older and mid-tier processors.

As of March 2026, the Core i7-8700K is best suited for users who prioritize single-threaded performance and are comfortable with older platforms. It remains a capable option for gaming, content creation, and general productivity, especially when paired with a high-end GPU. However, its lack of support for newer technologies like AVX-512 and PCIe 4.0, along with its outdated socket and memory bandwidth, make it less ideal for future-proofing. For new builds, modern alternatives offer better efficiency, performance, and feature sets.
