CPU Comparison
Intel Core i7-4860EQ vs Core i7-3840QM
A side-by-side comparison of specs, performance and value. The Intel Core i7-4860EQ is a specialized mobile processor introduced in late August 2013 as part of the fourth-generation Core family, specifically utilizing the Crystalwell architecture. Designed primarily for embedded systems and high-performance mobile workstations, this BGA-packaged chip features four physical cores and eight threads, offering robust multitasking capabilities for its era. Operating at a base frequency of 1.8 GHz with the ability to boost up to 3.2 GHz, it balances power consumption with demanding workloads, fitting within a 47-watt thermal envelope. What sets this processor apart is the integration of Intel HD Graphics 5200, backed by a massive 128MB L4 eDRAM cache, drastically improving integrated graphics performance. With 8MB of L3 cache and support for DDR3 memory, it provided a compelling solution for compact devices requiring strong graphical output without a discrete GPU. Its active production status underscores its niche industrial applications.

Our Verdict on Each
A highly capable embedded processor leveraging unique eDRAM technology to deliver reliable graphics and compute performance for long-life cycle applications.
Best for: Finding an Intel Core i7-4860EQ on the consumer market today is extremely rare, as it was never intended for standard DIY desktop builds or mainstream retail laptops. If you are sourcing replacement parts for an industrial system or repairing legacy embedded hardware, this processor provides excellent reliability and the unique advantage of HD 5200 graphics with eDRAM. For general consumers or modern system builders, investing in a 22nm Haswell-era chip makes little economic sense due to the lack of upgradeability and outdated platform features. Instead, seek modern alternatives with better efficiency. Purchase this only if maintaining an existing specialized system that explicitly requires the BGA 1364 socket and 47-watt thermal profile, as newer parts cannot be retrofitted into these proprietary embedded motherboard designs.
