CPU Comparison
Core i7-2920XM vs Intel Core i7-3820QM
A side-by-side comparison of specs, performance and value. The Intel Core i7-2920XM Extreme Edition is a flagship mobile processor from the Sandy Bridge generation, released in early 2011. As an 'XM' series chip, it features a fully unlocked multiplier, a rarity for mobile processors, allowing enthusiasts to overclock it. It boasts 4 cores and 8 threads, with a base clock of 2.5 GHz and a turbo boost of 3.5 GHz. Built on a 32nm process, it has a higher 55W TDP to accommodate the increased power limits. It includes 8MB of L3 cache and Intel HD 3000 integrated graphics. This processor was designed for the most demanding mobile workstations and gaming laptops of its time. While it is now obsolete, the i7-2920XM holds historical significance as one of the first truly enthusiast-grade mobile CPUs, offering desktop-like tuning capabilities in a portable form factor.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
High clocks and cache make it surprisingly capable for basic tasks.
8 threads and 8MB cache make quick work of office and compiling tasks.
Gaming
Great for older games when overclocked, but lacks modern support.
Handles older games easily and provides good frame rates with a discrete GPU.
Virtualization
VT-d and high clocks make it decent for legacy VMs.
Good for running light VMs on the go.
Efficiency
55W TDP is very high for a mobile chip, resulting in poor battery life.
22nm Ivy Bridge is less efficient than modern mobile chips.
