CPU Comparison
Intel Core i5-430M vs Intel Core i5-450M
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.
Marginally faster than the i5-430M in CPU-bound tasks, but the difference is barely noticeable in real use.
Gaming
The chipset-based GMA HD graphics are weaker than even Sandy Bridge's HD 3000. Not viable for any meaningful gaming.
Slightly better than the i5-430M but still entirely dependent on discrete graphics for any gaming capability.
Virtualization
Supports VT-x and VT-d but only 2 cores at relatively low clocks make it impractical.
Slightly more headroom than the 430M but still impractical for serious VM workloads.
Efficiency
The dual-die design was less efficient than Sandy Bridge's unified approach. 35 W delivers very little performance by modern standards.
Same 35 W TDP with only ~6% more frequency than the i5-430M, resulting in slightly worse performance per watt.

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 i5-450M is a minor clock speed increase over the i5-430M that arrived just months before Sandy Bridge rendered the entire Arrandale lineup obsolete. Only relevant for existing Socket G1 laptop owners considering a cheap upgrade.
Best for: Found in an existing laptop at no additional cost
