The Intel Core i5-14450HX is a 10-core, 16-thread high-performance mobile processor designed for budget-friendly gaming laptops. Released in January 2024, it utilizes the Raptor Lake-HX architecture on the BGA 1964 socket, featuring 6 P-Cores and 4 E-Cores. Operating at a 2.4 GHz base and boosting up to 4.8 GHz, it provides strong single-threaded gaming performance while maintaining a 55W base TDP. The 20MB L3 cache and native DDR5-5600 support ensure snappy system responsiveness. Unlike the 14500HX, it features the lower-end UHD 710 integrated graphics, clearly segmenting it as a cost-effective part meant to be paired with a dedicated mobile GPU. With a maximum turbo power of 157W, it scales aggressively under load, offering a compelling entry point into Intel's desktop-class HX mobile lineup for gamers who prioritize GPU spending over extreme CPU multi-threading.
The i5-14450HX is Intel's ticket into affordable gaming laptops. It cuts down the core count to 6P+4E compared to the 14500HX, focusing purely on gaming performance where single-threaded speed matters most. With 4.
8 GHz boost and DDR5-5600 support, it won't bottleneck mid-range mobile GPUs. The UHD 710 iGPU is basic, confirming this chip is meant for systems with dedicated graphics. If you want an HX-series laptop for gaming without paying for cores you won't use, the 14450HX is a smart, cost-effective choice.
Specifications
Performance
10 cores handle standard tasks well, but lag behind 14-core HX parts in rendering.
Adequate for 1-2 VMs, but limited by the 16 threads and 20MB cache.
Strong 1080p gaming performance, suitable for RTX 4050/4060 laptop GPUs.
Still a 55W base part, so battery life will be modest in gaming laptops.
- •4.8 GHz boost clock ensures high frame rates in single-threaded games
- •L3 cache reduced to 20MB, slightly impacting 1% lows
- •Must be paired with a dedicated GPU due to UHD 710
- •DLBoost supported
- •Not ideal for heavy local AI workloads

Architecture Overview
The Core i5-14450HX utilizes a cut-down Raptor Lake-HX die with 6 Raptor Cove P-cores and 4 Gracemont E-cores. This 10-core, 16-thread configuration is tailored for gaming workloads where high clock speeds matter more than massive multi-threading. The P-cores boost up to 4.8 GHz, while the E-cores handle background tasks up to 3.5 GHz.
CPU Design
The die harvest reduces the L3 cache to 20MB and the E-core cluster to a single module with 4MB of L2 cache. The P-cores retain their 2MB L2 cache each. This design minimizes latency in game engines while cutting costs for laptop manufacturers.
Memory Subsystem
The memory controller supports DDR5-5600 natively, ensuring ample bandwidth for modern gaming. Dual-channel memory is supported, and XMP profiles can be applied on unlocked laptop BIOS versions.
PCIe & I/O
16 PCIe Gen 5 lanes provide full bandwidth for the primary mobile GPU, and 4 Gen 4 lanes handle the boot NVMe SSD. This prevents storage and graphics bottlenecks in fast-paced games.
Overclocking
Despite being a budget HX part, it retains the unlocked multiplier. Enthusiasts with compatible laptops (usually high-end OEM models) can adjust power limits and core ratios to maximize performance.
- Higher max turbo frequency (4.8 GHz vs 4.6 GHz)
- Native DDR5-5600 support
- Refined power management
Key Highlights
- Strong 4.8 GHz single-core speed

- High 157W max turbo limits battery life
History
The Core i5-14450HX launched in January 2024 as the entry point to Intel's premium HX mobile lineup. </br> Recognizing that many gamers prioritize GPU power over extreme CPU core counts, Intel carved out this 10-core part from the full Raptor Lake die. By disabling two E-core clusters and swapping the iGPU to the UHD 710, Intel created a highly cost-effective chip specifically for budget gaming laptops.
This strategy allowed manufacturers to offer desktop-class architecture and DDR5 memory at lower price points, competing directly with AMD's efficient HS series. The 14450HX represents a maturation of the mobile market, where granularity in CPU SKUs allows for precise market targeting.
Improvements over Previous Generation
- Higher max turbo frequency (4.8 GHz vs 4.6 GHz)
- Native DDR5-5600 support
- Refined power management
