CPU Comparison
Intel Core i5-13420H vs Core i7-1355U
A side-by-side comparison of specs, performance and value. The Intel Core i5-13420H is a mobile processor designed for mainstream laptops, bridging the gap between ultra-portable efficiency and workstation-level multi-core capacity. Utilizing the Raptor Lake-H architecture, it features 8 cores and 12 threads, configured as four high-performance P-cores and four efficient E-cores. This hybrid setup allows the chip to deliver robust single-threaded performance for daily applications and light gaming, while the E-cores handle background tasks to preserve battery life. Operating at a 45W base TDP, it is suited for thicker chassis or gaming laptops that can accommodate robust cooling. It boosts up to 4.6 GHz on the P-cores, ensuring snappy responsiveness. The inclusion of Iris Xe Graphics with 80 Execution Units provides competent integrated graphics performance for multimedia consumption and casual gaming. With support for DDR5 and LPDDR5, the 13420H brings modern, high-bandwidth memory support to the mainstream mobile segment.

Our Verdict on Each
A solid mobile processor offering excellent multi-core performance for mid-range laptops, though it trails in single-core speed compared to higher HX models.
Best for: The Core i5-13420H is recommended for buyers looking at mid-range gaming laptops or performance-oriented student laptops. It provides an excellent balance of multi-core performance for schoolwork or coding, and battery efficiency for on-the-go use. If you are buying a laptop with an RTX 4050 or 4060 mobile GPU, this CPU will not bottleneck the system in most modern games. It is also suitable for light 1080p video editing. Buyers should ensure the laptop has adequate cooling, as 45W chips can throttle if the chassis is too thin. It should be avoided by professional content creators who need maximum multi-threaded rendering, who should instead look for HX-series chips with more cores. For mainstream mobile users, the 13420H is a highly capable and efficient choice.
