Intel’s new Core Ultra 5 245HX mobile processor is making waves, with early benchmarks showing it outperforms its desktop counterpart, the Core Ultra 5 245, and significantly outpaces its predecessor, the Core i5-14500HX. This mobile chip, based on the Arrow Lake-HX architecture, is delivering desktop-class performance, signaling a major leap in mobile computing capabilities.
Mobile Chip Redefines Performance
The Intel Core Ultra 5 245HX, a 14-core mobile processor, has demonstrated remarkable performance in initial PassMark benchmarks. It has shown a significant lead over previous mobile and even some desktop CPUs, challenging traditional notions of mobile computing power.
- The Core Ultra 5 245HX scored approximately 4,409 points in single-threaded performance and an impressive 40,059 points in multi-threaded workloads in PassMark.
- This represents a 26% increase in single-threaded speed and a 38% increase in multi-threaded speed compared to its predecessor, the Core i5-14500HX.
- Remarkably, the 245HX also outpaces the desktop Core Ultra 5 245, showing a 7% lead in single-core and an 8% advantage in multi-core performance.
Architectural Advancements
Intel has achieved this performance leap through a sophisticated hybrid architecture and optimized power management. The Core Ultra 5 245HX features:
- 6 Performance Cores (“Lion Cove”): Capable of clock speeds up to 5.1 GHz.
- 8 Efficient Cores (“Skymont”): Running at up to 4.5 GHz.
This configuration allows the chip to efficiently handle both demanding tasks and background processes. The mobile chip also boasts a higher maximum turbo power limit of 160W, compared to the desktop 245’s 121W, enabling sustained higher clock speeds.
Benchmark Comparison
Here’s a quick look at how the Core Ultra 5 245HX stacks up against key Intel processors in PassMark benchmarks:
| CPU | Single-Core (Points) | Multi-Core (Points) |
|---|---|---|
| Intel Core Ultra 5 245HX | ~4,409 | ~40,059 |
| Intel Core Ultra 5 245 | ~4,409 | ~37,930 |
| Intel Core i5-14500HX | ~3,608 | ~29,089 |
Real-World Implications and Availability
While synthetic benchmarks provide a strong indication of performance, real-world usage will depend on factors like thermal management and laptop design. However, these early results suggest that the Core Ultra 5 245HX will offer near-desktop performance in a mobile form factor, benefiting professionals in fields like video editing, 3D rendering, and software development.
The Core Ultra 5 245HX is part of Intel’s latest mobile HX lineup, which began rolling out in early 2025. Wider availability in high-end laptops is anticipated by late Q3 2025. These chips are expected to be integrated into larger, performance-focused machines with advanced cooling solutions, such as gaming laptops and mobile workstations.
