CPU Comparison
Intel Core i5-430M vs Core i7-640M
A side-by-side comparison of specs, performance and value. The Intel Core i5-430M is an Arrandale dual-core mobile processor built on a 32nm CPU die paired with a 45nm I/O and graphics die, featuring Hyper-Threading and a first-generation Turbo Boost implementation for mainstream 2010 laptops.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office tasks on Windows 7 but struggles with modern web applications and operating systems.
Strong single-core helps with older office apps.
Gaming
The chipset-based GMA HD graphics are weaker than even Sandy Bridge's HD 3000. Not viable for any meaningful gaming.
Requires a discrete GPU from that era for any gaming.
Virtualization
Supports VT-x and VT-d but only 2 cores at relatively low clocks make it impractical.
Capable of basic VMs but limited by 2 cores.
Efficiency
The dual-die design was less efficient than Sandy Bridge's unified approach. 35 W delivers very little performance by modern standards.
Typical 35W 32nm efficiency.

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
Read the full reviewAn extremely fast dual-core for its time, but heavily outdated by modern standards. The socketed design is a rare feature for laptops.
Best for: Upgrading a legacy Socket G1 laptop
