CPU Comparison
Intel Core i7-4810MQ vs Core i7-3840QM
A side-by-side comparison of specs, performance and value. The Intel Core i7-4810MQ is a high-performance mobile processor introduced in early 2014 as part of the 4th Generation Intel Core lineup, codenamed Haswell. Designed for premium gaming and workstation laptops, it features four physical cores and eight threads, providing excellent multitasking capabilities for its era. Operating at a base frequency of 2.8 GHz, it can dynamically boost up to 3.8 GHz using Intel Turbo Boost 2.0, adapting to thermal headroom to deliver robust burst performance. With a 47-watt thermal design power, it balances raw computing power with the thermal constraints of mobile chassis. It incorporates 6 MB of L3 SmartCache and supports dual-channel DDR3 memory. The integrated Intel HD 4600 graphics handle standard multimedia decoding and everyday display tasks, though serious gaming requires a discrete GPU. This CPU became a staple in countless mid-range and high-end laptops, offering a reliable computing experience for professionals and enthusiasts on the go.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
8 threads handle everyday multitasking and office workloads without issues.
Handles older productivity suites and web browsing fine.
Gaming
Handles older or eSports titles well when paired with a discrete GPU.
Adequate for 2012 games, but lacks power for modern AAA titles.
Virtualization
Can run light VMs, but limited by DDR3 bandwidth and 47W power.
Good support for light virtualization on the go.
Efficiency
22nm Haswell is not as efficient as modern 10nm or 14nm processes.
45W TDP was efficient then, but runs hot compared to modern mobile chips.
