CPU Comparison
Core i7-620M vs Intel Core i5-540M
A side-by-side comparison of specs, performance and value. The Intel Core i7-620M is a standard-voltage mobile processor launched in January 2010. Based on the Arrandale architecture, it features 2 cores and 4 threads with a base clock of 2.66 GHz and a turbo boost up to 3.33 GHz. With a 35W TDP, it was a popular choice for mainstream laptops. The 32nm CPU die is paired with a 45nm graphics/memory controller, offering 4MB of L3 cache, dual-channel DDR3 memory, and Intel HD Graphics (Ironlake) for everyday computing and multimedia tasks.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office apps well but struggles with modern web bloat.
Basic office tasks remain functional, but anything beyond simple documents will feel slow.
Gaming
Cannot handle modern games; IGP is too weak.
Cannot handle any modern 3D games. Only suitable for very old or browser-based titles.
Virtualization
Good for basic VMs but limited by 2 cores.
Two cores with 3MB L3 cache are insufficient for any practical VM workloads.
Efficiency
Standard efficiency for 32nm, but modern chips are vastly better.
35W TDP was reasonable for 2010 but is far less efficient than modern mobile chips.
