CPU Comparison
Intel Core i5-4200U vs Intel Core i5-450M
A side-by-side comparison of specs, performance and value. The Intel Core i5-4200U is a dual-core, ultra-low voltage mobile processor launched in mid-2013 as part of the 4th Generation Core (Haswell) lineup. With a 15-watt TDP, it became the quintessential processor for the era's Ultrabooks, striking a balance between power efficiency and everyday performance. It features two physical cores and four threads thanks to Intel's Hyper-Threading technology, allowing it to handle multitasking with relative ease. The base clock speed is set at 1.6 GHz, dynamically boosting up to 2.6 GHz via Intel Turbo Boost technology when demanding workloads require extra performance. The processor is equipped with 3 MB of SmartCache and integrates Intel HD Graphics 4400, offering smooth 1080p video playback and the ability to play light casual games. It was a defining chip for mainstream thin-and-light laptops, offering an excellent blend of battery life and productivity performance.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Noticeable lag with modern multitasking.
Marginally faster than the i5-430M in CPU-bound tasks, but the difference is barely noticeable in real use.
Gaming
Handles only old or 2D indie games.
Slightly better than the i5-430M but still entirely dependent on discrete graphics for any gaming capability.
Virtualization
Can run one light VM.
Slightly more headroom than the 430M but still impractical for serious VM workloads.
Efficiency
Great battery life for its time.
Same 35 W TDP with only ~6% more frequency than the i5-430M, resulting in slightly worse performance per watt.
Specialized Performance
AI / ML
