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.
Highest single-threaded Arrandale i5 performance helps slightly in office tasks, but the difference from lower SKUs is minimal in practice.
Gaming
The chipset-based GMA HD graphics are weaker than even Sandy Bridge's HD 3000. Not viable for any meaningful gaming.
Identical to the socketed i5-580M. First-gen Intel HD Graphics prevents any meaningful gaming experience with modern titles.
Virtualization
Supports VT-x and VT-d but only 2 cores at relatively low clocks make it impractical.
VT-x and VT-d present, but 2 cores and 3MB cache make any serious virtualization impractical.
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 turbo at same power shows good process binning.
Specialized Performance
AI / ML
- No AI acceleration
- No AVX support
- Insufficient compute for any AI workload
- No AI acceleration capabilities
Content Creation
Gaming
- Graphics handled by chipset, not CPU
- GMA HD is extremely limited
- No modern API support whatsoever
- Performance identical to socketed i5-580M
- 3.333 GHz turbo irrelevant when GPU is the bottleneck
- Only viable for very old or lightweight games

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 BGA i5-580M delivers the same impressive 3.333 GHz turbo as the socketed variant but in a non-upgradeable package, making it solely relevant for repair and preservation of specific laptop models.
Best for: Exact replacement for a failed BGA i5-580M (SLC29) in a specific laptop model during board-level repair
