Core i7-3920XM Details

Ranking #906 of 2060 in overall performance, the Intel Core i7-3920XM reflects a processor from an earlier era of mobile computing, launched in April 2012. Though now over a decade old, it remains a compelling example of Intel’s mobile high-end offerings during the Ivy Bridge generation. Built on a 22 nm process and featuring a 55 W TDP, the i7-3920XM was designed for high-performance laptops and mobile workstations, where thermal constraints were balanced with computational demands. Its architecture, while outdated by today's standards, still delivers a solid foundation for understanding how mobile CPUs evolved toward today's multi-threaded, power-efficient designs.

At its core, the i7-3920XM features four physical cores and eight threads thanks to Intel Hyper-Threading, allowing it to handle a wide range of multitasking workloads efficiently. With a base clock of 2.9 GHz and a turbo frequency of up to 3.8 GHz, the processor benefits from dynamic frequency scaling to optimize performance and power consumption. It operates on the FCPGA988 socket and supports dual-channel DDR3 memory up to 1600 MHz, with a maximum capacity of 32 GB. The L3 cache measures 7.629 MiB, while L1 and L2 caches are 0.061 MiB and 0.244 MiB respectively, contributing to efficient data access and reduced latency.

Integrated into the processor is Intel HD Graphics 4000, a GPU capable of driving up to three displays at a maximum frequency of 1.3 GHz. While this graphics solution is no match for modern discrete GPUs, it enables basic multimedia playback and light graphical tasks. The processor also supports advanced technologies such as AVX, AVX2, AES-NI, and Intel VT-x, making it suitable for virtualization, encryption, and scientific computation. Additionally, the unlocked multiplier allows for straightforward overclocking, a rare feature in mobile CPUs of its time.

In benchmark testing, the i7-3920XM achieves an overall score of 4955, placing it among mid-tier processors in the broader performance landscape. Its single-core score of 5049 ranks it at #910, slightly ahead of some modern low-power processors but behind today’s high-end designs. The multicore score of 4815 positions it at #824, indicating that while it holds its own in multi-threaded applications, its performance is outpaced by contemporary multi-core CPUs. In the top 50 overall list, it trails significantly behind leading processors like the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, which exceed 9000 in score.

As of March 2026, the Core i7-3920XM is best suited for legacy systems, retro computing enthusiasts, or specialized applications where compatibility with older software or hardware is required. While its performance is outdated compared to modern standards, its robust feature set and overclocking capability make it a notable piece of Intel's mobile history. For users seeking high-end mobile performance today, newer processors with higher core counts, faster memory, and improved architectures are far more suitable.
