CPU Comparison
Core i5-13450HX vs Intel Core i9-13905H
A side-by-side comparison of specs, performance and value. The Intel Core i5-13450HX is a desktop-class mobile processor designed for budget gaming laptops. Part of the Raptor Lake-HX family, it brings an unlocked multiplier and higher power limits to the mobile space. It features 10 cores (6 Performance + 4 Efficient) and 16 threads, utilizing a 55W base TDP. With a max turbo of 4.6 GHz and 20MB of L3 cache, it delivers strong gaming performance. Unlike standard H-series chips, it uses a larger 257mm² die borrowed from desktop silicon, offering 20 PCIe 5.0 lanes for extensive expansion. The integrated UHD Graphics 710 is minimal, intended purely for display output. Released in early 2023, the 13450HX targets users who want desktop replacement performance and overclocking capabilities in a laptop without breaking the bank.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
10 cores and 20MB cache make it great for heavy productivity.
Exceptional multi-threaded performance for video editing, rendering, and multitasking, competing with top-tier mobile CPUs.
Gaming
Handles high-refresh-rate gaming; not a bottleneck for RTX 4060/4070.
