CPU Comparison
Intel Core i7-3632QM vs Core i7-3940XM
A side-by-side comparison of specs, performance and value. The Intel Core i7-3632QM is a highly efficient mobile processor introduced in late 2012 as part of the Ivy Bridge lineup. What sets this quad-core chip apart from its siblings is its remarkably low 35-watt thermal design power, making it ideal for thinner and lighter laptops that still require workstation-class multitasking capabilities. It features four cores and eight threads, operating at a base frequency of 2.2 GHz and dynamically boosting up to 3.2 GHz via Intel Turbo Boost 2.0. Despite the lower power envelope, it retains a 6 MB L3 SmartCache and supports dual-channel DDR3 memory. The integrated Intel HD 4000 graphics handle everyday multimedia tasks efficiently. This CPU was a favorite for premium ultraportables and thin-and-light gaming laptops, proving that users did not have to sacrifice multi-threaded performance for portability and battery life in the Ivy Bridge era.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
8 threads handle everyday multitasking and office workloads smoothly.
High clocks keep it surprisingly snappy for basic tasks.
Gaming
Can handle older games or light eSports, but thermal limits in thin laptops restrict sustained performance.
Excellent for 2012 games, can still handle older esports titles.
Virtualization
Capable of running light VMs, though limited by thermal constraints.
Great for running VMs on the go.
Efficiency
Excellent power-to-performance ratio for a 2012 mobile chip.
55W TDP is terrible for battery life.
