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.
Intel's Core i5-13450HX brings true desktop silicon to the mobile market. Unlike the BGA-reballed H-series, the HX uses a larger 257mm² die providing 6 Performance cores and 4 Efficient cores for 10 total cores and 16 threads. The standout feature is the unlocked multiplier, allowing enthusiasts to overclock the chip in compatible laptops.
With a base TDP of 55W and PL2 of 157W, it requires robust cooling but delivers exceptional multi-threaded performance. It offers 20 PCIe 5.0 lanes, enabling direct connections for a GPU and fast NVMe storage.
The integrated UHD 710 graphics are basic, meaning a discrete GPU is mandatory. For gamers looking for desktop replacement performance at a lower price point, the 13450HX is a compelling entry point.

Architecture Overview
The Core i5-13450HX utilizes the Raptor Lake-HX architecture, which is essentially desktop Raptor Lake silicon adapted for mobile BGA packaging. Built on the 10nm Intel 7 process, it features a larger 257mm² die compared to the H-series. This chip includes 6 Raptor Cove Performance cores and 4 Gracemont Efficient cores, totaling 10 cores and 16 threads. The P-cores boost up to 4.6 GHz, while the E-cores handle background tasks. Unlike the H-series, the HX features 20 PCIe 5.0 lanes directly from the CPU, allowing for x16 GPU and x4 NVMe configurations without relying on the PCH. It also features a larger 20MB L3 cache. The integrated graphics are downgraded to UHD Graphics 710 with just 16 Execution Units, serving purely as a display output fallback. The unlocked multiplier allows enthusiasts to tweak frequencies via XTU.

History
Introduced on January 4th, 2023, the Core i5-13450HX marked a shift in Intel's mobile strategy. Instead of merely adapting low-power mobile chips for gaming, Intel took its desktop Raptor Lake silicon and packaged it for mobile form factors under the HX banner. The 13450HX was designed to offer extreme value in the budget gaming laptop segment.
By providing 6 P-cores, an unlocked multiplier, and 20 PCIe lanes, Intel allowed manufacturers to create highly competitive desktop replacements. This chip aimed to capture enthusiasts who wanted desktop overclocking capabilities in a portable package. The release of the HX series blurred the lines between desktop and mobile performance, giving users access to workstation-class I/O and power limits previously unseen in the i5 mobile tier.
Improvements over Previous Generation
