CPU Comparison
Intel Core i5-450M vs Core i7-620M
A side-by-side comparison of specs, performance and value. The Intel Core i5-450M is a slightly higher-clocked Arrandale dual-core mobile processor released in September 2010, offering 2.4 GHz base and 2.667 GHz turbo speeds with the same dual-die 32nm/45nm design as the i5-430M.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Marginally faster than the i5-430M in CPU-bound tasks, but the difference is barely noticeable in real use.
Struggles with modern web and office software.
Gaming
Slightly better than the i5-430M but still entirely dependent on discrete graphics for any gaming capability.
Can run very old games, but lacks modern instructions.
Virtualization
Slightly more headroom than the 430M but still impractical for serious VM workloads.
Can run basic VMs but lacks RAM support.
Efficiency
Same 35 W TDP with only ~6% more frequency than the i5-430M, resulting in slightly worse performance per watt.
35W for 2 cores is inefficient by modern standards.

AI / ML
- No AI capabilities
- No AVX support
- Completely unsuitable for AI workloads
- No AI capabilities.
Content Creation
Gaming
- Graphics on chipset, not CPU
- GMA HD extremely limited
- Requires discrete GPU for any gaming
- Ironlake graphics are too weak; relies on discrete GPUs. Lacks AVX2.
