Performance Compared

Productivity

Intel Core i5-430MBest25

Handles basic office tasks on Windows 7 but struggles with modern web applications and operating systems.

Core i7-620UM8

Will struggle immensely with modern web and software.

Gaming

Intel Core i5-430MBest8

The chipset-based GMA HD graphics are weaker than even Sandy Bridge's HD 3000. Not viable for any meaningful gaming.

Core i7-620UM2

No modern gaming capabilities.

Virtualization

Intel Core i5-430MBest15

Supports VT-x and VT-d but only 2 cores at relatively low clocks make it impractical.

Core i7-620UM5

Lacks the power for practical virtualization.

Efficiency

Intel Core i5-430MBest20

The dual-die design was less efficient than Sandy Bridge's unified approach. 35 W delivers very little performance by modern standards.

Core i7-620UM15

Good for 2010, obsolete now.

Our Verdict on Each

The i5-430M was a competent mid-range laptop CPU in early 2010, but its Arrandale architecture with separate CPU and I/O dies, lack of on-die GPU, and absence of AVX make it thoroughly obsolete today.

Best for: Upgrading an existing Socket G1 laptop with a used i7-620M at minimal cost
