Core i7-4940MX Details

Launched in January 2014, the Intel Core i7-4940MX stands as a high-end mobile processor from the Haswell era, designed for demanding workstations and performance-oriented laptops. Built on a 22 nm process and featuring a 64-bit architecture, it represents a premium offering in Intel's mobile lineup, targeting users who require extreme multi-threaded performance in portable systems. With a TDP of 57 W, it balances power and efficiency while maintaining a strong performance profile for its time.

The Core i7-4940MX is a quad-core processor with eight threads enabled via Hyper-Threading, allowing it to handle complex multitasking and parallel workloads effectively. It operates at a base frequency of 3.1 GHz and can boost up to 4.0 GHz under load, thanks to Intel's Turbo Boost technology. The processor integrates 8 MB of L3 cache, which significantly aids in reducing memory latency and improving data throughput. It supports DDR3L-1600 memory in a dual-channel configuration, delivering a maximum memory bandwidth of 25.6 GB/s, and is compatible with Socket FCLGA2011, a high-end desktop interface adapted for mobile workstations.

Integrated graphics come in the form of the Intel HD 4600, capable of running basic multimedia and light gaming with a base frequency of 400 MHz and a burst frequency of 1350 MHz. It supports up to three displays simultaneously, making it suitable for multi-monitor setups. The processor also supports a wide range of modern features, including AVX, AVX2, AES-NI, and Intel's virtualization technologies (VT-x, VT-d), enabling efficient virtual machine performance and enhanced security.

In benchmark testing, the Core i7-4940MX achieves an overall score of 5272, placing it at #640 out of 2060 processors. Its single-core performance scores 5486, ranking #561, and its multicore score reaches 4951, placing it at #674. These results indicate that while the processor remains competitive in single-threaded applications, its multicore performance is more modest compared to modern CPUs. It falls behind contemporary processors like the Ryzen 9 7950X3D and Core Ultra 9 285K, which dominate the top tiers of performance.

Despite its age, the Core i7-4940MX still holds relevance in legacy systems and specialized environments where high single-threaded performance and robust feature support are prioritized. As of March 2026, it is no longer a mainstream option but remains a capable CPU for users who value its unlocked multiplier and extensive feature set. Its performance is most suitable for content creation, engineering workloads, and professional applications that benefit from its high clock speeds and strong integrated graphics capabilities.
