Overview
Built on Intel’s 14nm Coffee Lake microarchitecture, dual-core silicon with Hyper-Threading yields four logical execution threads operating at an unboosted 3.70 GHz base clock. The processor interfaces with the system via an 8 GT/s Direct Media Interface (DMI) and incorporates 512 KB of L2 cache alongside 4 MB of shared L3 cache. Graphics processing and multi-monitor output are driven by an integrated Intel UHD Graphics 610 engine, which supports up to three concurrent displays without requiring discrete graphics hardware, establishing a functional foundation for standard office workflows, video playback, and basic desktop environments.
Packaged for the LGA 1151 socket with a standard 1.48 x 1.48 in (37.5 x 37.5 mm) footprint, the processor utilizes a nickel-plated copper integrated heat spreader bonded to the substrate to protect the die and ensure uniform contact with thermal solutions. Operating within a modest 58W thermal design power and a 100°C maximum junction temperature limit, cooling demands remain low enough to run reliably on basic aluminum heatsinks. On the firmware side, platform stability and security maintenance have addressed vulnerability disclosures such as CVE-2020-0543 (Special Register Buffer Data Sampling) through official Intel microcode and motherboard BIOS updates, preserving system integrity.
In everyday deployment, the lack of Turbo Boost technology keeps clock frequencies strictly tethered to the 3.70 GHz base rate, while the two-core physical topology presents noticeable bottlenecks when tackling heavy multithreaded compute workloads or dense multitasking. While the LGA 1151 socket permits clear drop-in upgrade paths to higher-tier 8th and 9th Generation Core processors on compatible motherboards, the silicon serves primarily as an efficient, entry-tier computing engine tailored for lightweight and transaction-oriented operational roles.
