CPU Comparison
Intel Core i5-430M vs Intel Core i5-580M
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.
The highest single-threaded performance of any Arrandale i5 translates to slightly better responsiveness in office applications.
Gaming
The chipset-based GMA HD graphics are weaker than even Sandy Bridge's HD 3000. Not viable for any meaningful gaming.
The extra 133 MHz turbo provides a negligible improvement in gaming, as the first-gen Intel HD GPU remains the binding constraint.
Virtualization
Supports VT-x and VT-d but only 2 cores at relatively low clocks make it impractical.
Still fundamentally limited by 2 cores and 3MB cache, but the higher clock helps slightly in CPU-bound VM tasks.
Efficiency
The dual-die design was less efficient than Sandy Bridge's unified approach. 35 W delivers very little performance by modern standards.
Same 35W TDP as all Arrandale i5s. Higher clocks at the same power budget show good 32nm process maturity.
Specialized Performance
AI / ML
- No AI acceleration
- No AVX support
- Insufficient compute for any AI workload
- No AI acceleration of any kind
- Completely unsuitable for AI workloads
Content Creation
Gaming
- Graphics handled by chipset, not CPU
- GMA HD is extremely limited
- No modern API support whatsoever
- 3.333 GHz turbo does not overcome integrated graphics limitations
- Slightly better CPU-bound game performance than i5-560M
- Still unplayable in any modern 3D title

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 reviewThe i5-580M is the best Arrandale Core i5 you can buy for a Socket G1 laptop, offering the highest turbo frequency in the lineup, though it remains obsolete for modern use.
Best for: As a final upgrade for a Socket G1 laptop where maximum Arrandale performance is desired
