Intel Core Ultra 7 155H vs Intel Core i7-13620H: Full Comparison
Introduction
Choosing a laptop processor involves balancing performance, efficiency, and features across different generations. This comparison examines the Intel Core Ultra 7 155H, part of the new “Meteor Lake” architecture, against the previous-generation Intel Core i7-13620H from the “Raptor Lake” family. Understanding their differences in core design, integrated graphics, AI capabilities, and platform features can help clarify which processor aligns better with specific computing needs, from content creation to everyday productivity.
Architecture and Manufacturing Process
The fundamental difference lies in their underlying design. The Core i7-13620H is based on the monolithic Raptor Lake architecture, fabricated on an Intel 7 process. In contrast, the Core Ultra 7 155H introduces Intel’s first client chiplet design (Meteor Lake), which separates the compute, graphics, and I/O tiles. It is built on a newer Intel 4 process for the compute tile and incorporates a TSMC-made graphics tile. This chiplet approach is designed to improve efficiency and performance partitioning.
- Core Ultra 7 155H: Meteor Lake chiplet design (Intel 4 process for CPU).
- Core i7-13620H: Monolithic Raptor Lake design (Intel 7 process).
CPU Core Configuration and Performance
Both processors feature a hybrid architecture combining Performance-cores (P-cores) and Efficient-cores (E-cores), but their configurations differ.
- Core Ultra 7 155H: Features 16 cores (6 P-cores, 8 E-cores, and 2 new Low Power E-cores) and 22 threads. Its P-cores have a max turbo frequency of 4.8 GHz. The addition of Low Power E-cores on a separate tile is intended to handle background tasks with minimal power draw.
- Core i7-13620H: Configured with 10 cores (6 P-cores and 4 E-cores) and 16 threads. Its P-cores can reach a higher max turbo frequency of 4.9 GHz. In purely multi-threaded CPU workloads, its core count can be advantageous, though it lacks the dedicated low-power island.
In typical use, the Core i7 may show strong results in sustained multi-core tasks, while the Core Ultra 7 is designed for better overall system efficiency.
Integrated Graphics (iGPU)
This is one of the most significant generational leaps. The Core Ultra 7 series features the new Intel Arc graphics.
- Core Ultra 7 155H: Equipped with an Intel Arc GPU featuring 8 Xe-cores. This represents a major upgrade, offering performance that can handle 1080p gaming at low-to-medium settings and significantly accelerated media encoding.
- Core i7-13620H: Uses the older Intel UHD Graphics (based on Xe-LP architecture) with 64 execution units. It is suitable for display output and basic tasks but offers limited gaming or creative application performance.
For users without a discrete GPU, the Core Ultra 7 provides a substantially better visual and creative experience.
AI and NPU
Artificial intelligence acceleration is a key focus of the new generation.
- Core Ultra 7 155H: Includes a dedicated Neural Processing Unit (NPU) on-die. This is designed to efficiently handle sustained AI workloads, like background blur in video calls or local AI assistant tasks, freeing up the CPU and GPU.
- Core i7-13620H: Lacks a dedicated NPU. AI tasks are handled by the CPU or the integrated GPU, which can be less efficient for continuous AI processing.
Power Efficiency and Platform Features
The Core Ultra platform brings several forward-looking features.
- Power Profile: Both have a similar base TDP of 28W, but the Core Ultra 7’s chiplet design and Low Power E-cores aim for better battery life in thin-and-light laptops during light usage.
- Connectivity: The Core Ultra 7 platform typically supports newer standards like Wi-Fi 7 and Bluetooth 5.4, while the Core i7 platform is commonly paired with Wi-Fi 6E.
- Memory Support: Both support DDR5 and LPDDR5/x memory, though the Core Ultra 7 can also support LPDDR5x-7467, offering higher potential bandwidth.
