Core Count and Architecture: A Tale of Two Designs

The Intel Core i9 13905H boasts a remarkable 14 cores, comprising 6 performance cores (P-cores) and 8 efficient cores (E-cores). This hybrid architecture, known as Raptor Lake, allows the CPU to seamlessly switch between high-power P-cores for demanding tasks and energy-efficient E-cores for lighter workloads.
On the other hand, the Intel Core Ultra 7 155H employs a different approach with its 12 cores, all of which are performance cores. This “performance-first” strategy, dubbed Meteor Lake, aims to deliver exceptional single-threaded performance, crucial for applications that heavily rely on a single core.

Clock Speeds: A Race to the Top

The Intel Core i9 13905H has a base clock speed of 2.6 GHz, which can boost up to 5.4 GHz for its P-cores. This impressive boost capability enables the CPU to unleash its full potential when required.
The Intel Core Ultra 7 155H, while lacking E-cores, compensates with a higher base clock speed of 2.7 GHz and a boost clock speed of 5.5 GHz. This slight edge in clock speeds might translate to faster performance in certain scenarios.

Cache: The Memory Master

The Intel Core i9 13905H features a generous 24 MB of L3 cache, providing ample space for frequently accessed data. This extensive cache helps to reduce latency and improve overall performance, particularly in multi-threaded applications.
The Intel Core Ultra 7 155H, despite its “performance-first” approach, has a smaller 18 MB L3 cache. While this may not be a significant drawback in all cases, it could impact performance in scenarios where data access is frequent and memory bandwidth is critical.

Integrated Graphics: Visual Prowess

Both CPUs come equipped with integrated graphics, offering a convenient solution for basic tasks like web browsing and video playback. The Intel Core i9 13905H utilizes the Intel Iris Xe graphics, while the Intel Core Ultra 7 155H features the newer Intel Arc Graphics.
While both graphics solutions offer solid performance for everyday use, the Intel Arc Graphics boasts enhanced features and capabilities, particularly in gaming. It supports DirectX 12 Ultimate and offers improved performance compared to its predecessor, making it a more appealing option for those seeking a smoother gaming experience.

Power Consumption: Balancing Performance and Efficiency

The Intel Core i9 13905H, with its hybrid architecture, is designed to strike a balance between performance and power efficiency. Its E-cores enable the CPU to handle lighter workloads while consuming less power. This can translate to longer battery life in laptops.
The Intel Core Ultra 7 155H, with its focus on performance, might consume slightly more power compared to the Intel Core i9 13905H. However, its improved power management features and the latest architecture advancements aim to minimize power consumption without compromising performance.

Real-World Performance: Putting the CPUs to the Test

The Intel Core i9 13905H and Intel Core Ultra 7 155H deliver impressive performance in real-world scenarios. The Intel Core i9 13905H excels in multi-threaded workloads, thanks to its hybrid architecture and numerous cores. It’s a powerhouse for tasks like video editing, 3D rendering, and multi-tasking.
