Core i7-8670 Details

As of March 2026, the Intel Core i7-8670 remains a capable desktop processor, though its relevance has diminished with the rapid evolution of modern computing hardware. Launched in January 2018, this Coffee Lake-based CPU has a 14 nm process node and is built on the 6-core, 12-thread architecture, offering a base frequency of 3.1 GHz and a turbo boost up to 4.4 GHz. With a 65 W TDP and LGA-1151 socket compatibility, it maintains a balanced power profile suitable for mainstream desktop workloads. While no longer a flagship, it still holds its own in the mid-tier segment, particularly for users who prioritize integrated graphics and efficient power consumption.

The Core i7-8670's overall performance is reflected in its benchmark results: it scores 5,992 in the overall category, placing it at #254 among 2,060 processors. In single-core performance, it achieves a score of 6,542, ranking #109, which highlights its strong per-thread efficiency despite its age. This strength is evident in applications that rely on high clock speeds, such as gaming or lightweight content creation. However, its multicore performance, scoring 5,168 and ranking #529, reveals a more modest capability when handling parallelized workloads. This gap between single-core and multicore performance suggests the processor is better suited for tasks that don't require heavy parallel processing.

The processor supports DDR4-2666 memory over a dual-channel interface, with a maximum capacity of 64 GB. It features 12 MB of L3 cache and 1.5 MB of L2 cache, with a 0.375 MB L1 cache split between instruction and data. These cache specifications are adequate for its time but are now outpaced by modern designs with larger and more intelligent caching systems. The integrated UHD Graphics 630 GPU, with 24 execution units and a base frequency of 350 MHz (up to 1.2 GHz), provides basic graphical capabilities suitable for office use, media playback, and light gaming. While not powerful by today's standards, it offers a cost-effective solution for systems without a discrete GPU.

Intel’s inclusion of advanced features like AVX, AVX2, and AES-NI ensures compatibility with modern software and encryption tasks. The processor also supports hardware virtualization, Intel VT-x and VT-d, making it suitable for virtual machine environments. Despite its age, the Core i7-8670 remains competitive against some newer CPUs in its class, such as the Ryzen 5 4600U and Ryzen 5 1600, though it falls behind more recent models like the Ryzen 7 7736U and Core i7-8700K. For users seeking a reliable, power-efficient processor for general computing and occasional multimedia tasks, the i7-8670 still offers solid value, albeit with clear limitations in raw performance compared to current-generation offerings.
