Intel Core Ultra 7 155H vs Intel Core i5 1335U: Full Comparison
Introduction
Choosing a laptop often involves understanding the processor at its heart. This comparison looks at two distinct Intel CPUs: the newer Core Ultra 7 155H from the “Meteor Lake” generation and the Core i5-1335U from the previous “Raptor Lake” line. They represent different design philosophies—high performance versus balanced efficiency. This article will break down their architectures, performance capabilities, and typical use cases to help clarify which chip might be better suited for specific computing needs.
Architecture and Core Design
The fundamental difference between these processors lies in their architecture and core configuration, which dictates their performance profile and power consumption.
- Intel Core Ultra 7 155H: This is part of Intel’s new Meteor Lake lineup, featuring a chiplet design. It typically combines 16 cores (6 Performance-cores, 8 Efficient-cores, and 2 Low Power Efficient-cores) and 22 threads. A key feature is the integrated Intel Arc graphics and a dedicated AI accelerator (NPU).
- Intel Core i5-1335U: Based on the older Raptor Lake architecture, it uses a more traditional monolithic design. It features 10 cores (2 Performance-cores and 8 Efficient-cores) and 12 threads. Its integrated graphics are Intel Iris Xe.
The Core Ultra 7’s hybrid design with low-power cores and NPU is geared toward smarter power management and AI tasks, while the Core i5 U-series focuses on a balance of performance within a strict power envelope.
Performance and Power
Performance is closely tied to the Thermal Design Power (TDP), which indicates the heat dissipation a laptop’s cooling system needs to handle.
- Core Ultra 7 155H: With a base TDP of 28W and a maximum turbo power that can be much higher, this chip is designed for sustained high performance. It excels in multi-threaded workloads like video editing, 3D rendering, and coding. The more powerful Arc graphics also provide a noticeable boost for light gaming and creative applications over traditional integrated graphics.
- Core i5-1335U: This processor operates at a lower base TDP of 15W, making it more power-efficient. It is well-suited for everyday tasks such as web browsing, office applications, media consumption, and light multitasking. Performance is generally adequate for standard use but can be limited under sustained heavy loads.
In general, the Core Ultra 7 155H will deliver significantly higher CPU and graphics performance, but at the cost of higher power consumption and potentially more heat.
Use Cases and Typical Laptops
The choice between these processors often dictates the form factor and purpose of the laptop you will find them in.
- Core Ultra 7 155H Laptops: You will typically find this processor in larger “content creation” laptops, high-performance thin-and-lights, and some gaming laptops that prioritize battery life. They are aimed at users who need strong multi-core performance for professional or demanding hobbyist work.
- Core i5-1335U Laptops: This chip is a staple in mainstream ultrabooks, budget-friendly laptops, and business notebooks where all-day battery life, portability, and cool, quiet operation are primary concerns. It targets students, professionals, and general users.
Features and Technologies
Beyond raw performance, the generational difference introduces new features.
- AI and NPU: The Core Ultra 7’s integrated NPU is designed to efficiently handle AI workloads, which can benefit features like background blur in video calls, photo editing enhancements, and other AI-accelerated tasks in supported applications. The Core i5-1335U lacks a dedicated NPU.
- Graphics: The Intel Arc graphics in the Core Ultra 7 represent a generational leap over the Iris Xe graphics in the Core i5, offering better performance in gaming and creative apps.
- Connectivity: Both support modern standards like Wi-Fi 6E and Thunderbolt 4, though newer Core Ultra systems may be more likely to include the latest Wi-Fi 7 and Bluetooth 5.4.

Frequently Asked Questions (FAQ)
What is the main difference between the Core Ultra 7 155H and Core i5-1335U?
The main difference lies in their performance tier and power target. The Core Ultra 7 155H is a higher-power (28W) chip with more cores, stronger graphics, and an AI NPU for demanding tasks. The Core i5-1335U is a lower-power (15W) chip focused on efficiency and is commonly found in ultraportable laptops for everyday use.
Which processor is better for gaming?
The Intel Core Ultra 7 155H, with its more powerful Intel Arc integrated graphics, will generally provide a better gaming experience for light to moderate gaming compared to the Iris Xe graphics in the Core i5-1335U. For serious gaming, a laptop with a discrete GPU is still recommended.
Does the Core i5-1335U have an AI NPU like the Core Ultra 7?
No, the Intel Core i5-1335U does not include a dedicated Neural Processing Unit (NPU). AI tasks on systems with this processor are handled by the CPU or GPU.
Will a Core i5-1335U laptop have better battery life?
