Intel Core Ultra 7 155H vs Apple M1: Full Comparison
Introduction
Comparing the Intel Core Ultra 7 155H and the Apple M1 processor involves looking at two different approaches to modern computing. The M1 marked a significant shift for Apple towards its own silicon, while the Core Ultra series represents Intel’s evolution with a focus on AI and integrated graphics. This comparison will break down their architectures, performance in different tasks, platform ecosystems, and efficiency to help you understand their key differences and similarities.
Architecture and Platform
The fundamental difference lies in their design philosophy and the systems they power.
- Intel Core Ultra 7 155H: This is an x86 processor built on Intel’s 4 process node. It features a hybrid core design with Performance-cores (P-cores), Efficient-cores (E-cores), and a new Low Power Island for background tasks. It is designed to run the Windows operating system and is available in laptops from a wide variety of manufacturers.
- Apple M1: This is an ARM-based system-on-a-chip (SoC) built on a 5nm process. It uses a unified memory architecture, where the CPU, GPU, and other components share a single pool of RAM. It is designed exclusively for Apple’s macOS (and iPadOS) and is found in MacBook Air, MacBook Pro, Mac mini, and iMac models.
The platform choice—Windows vs. macOS—is a primary deciding factor, as software compatibility differs significantly.
CPU and General Performance
Both chips offer strong performance for everyday tasks, but their strengths can diverge.
- Core Counts: The Core Ultra 7 155H typically features 16 cores (6 P-cores + 8 E-cores + 2 Low Power E-cores) and 22 threads. The Apple M1 has 8 cores (4 high-performance + 4 high-efficiency).
- Single-Core Tasks: In applications that rely on a single thread, both processors are generally very capable, with performance often being comparable for standard office and web workloads.
- Multi-Core and Sustained Workloads: The higher thread count of the Core Ultra 7 can provide an advantage in heavily multi-threaded applications like video encoding, 3D rendering, or scientific computing. The M1’s unified architecture and efficiency often allow it to perform very well in sustained creative workloads within optimized macOS applications.
Graphics and AI Performance
This is an area where the generational and architectural differences are pronounced.
- Integrated Graphics: The Intel Core Ultra 7 155H includes Intel Arc graphics, which represents a significant generational leap for Intel’s iGPUs. It typically offers better performance for light gaming and GPU-accelerated tasks compared to Intel’s previous generations. The Apple M1 integrates a 7-core or 8-core GPU that is known for its efficiency and strong performance in supported creative and graphics applications.
- AI Acceleration: A key feature of the Core Ultra series is the dedicated Neural Processing Unit (NPU). This is designed to handle AI workloads locally, which can benefit features like background blur in video calls, photo editing enhancements, and certain creative software filters. The Apple M1 also has a Neural Engine designed for similar machine learning tasks, and it is widely utilized within macOS and its native apps.
Power Efficiency and Battery Life
Efficiency is a critical metric for mobile processors.
- Apple M1: The M1 is renowned for its high performance-per-watt. MacBooks equipped with the M1, such as the MacBook Air, are typically known for offering very long battery life under general usage conditions, partly due to the efficiency of the ARM architecture and deep software/hardware integration.
- Intel Core Ultra 7 155H: As part of Intel’s “Meteor Lake” architecture, this chip places a strong emphasis on power efficiency, particularly with its Low Power Island for background tasks. Battery life in laptops using this chip has generally improved compared to previous Intel generations, but actual results can vary more widely depending on the laptop manufacturer’s design, display, and battery size.

FAQ
What is the main difference between the Intel Core Ultra 7 155H and the Apple M1?
The main differences are architectural and platform-based. The Core Ultra 7 is an x86 chip for Windows laptops with a focus on AI via its NPU, while the M1 is an ARM-based SoC designed exclusively for Apple’s macOS/iPadOS ecosystem, known for its high efficiency and unified memory.
Which processor is better for gaming?
For light gaming, the integrated Intel Arc graphics in the Core Ultra 7 155H typically offer an advantage in terms of compatibility and performance with a wider range of Windows-based games. The Apple M1 can run many games well, especially those optimized for macOS or via translation layers, but the overall gaming library on Windows is larger.
Does the Intel Core Ultra 7 have better battery life than the Apple M1?
Battery life depends heavily on the specific laptop design. While the Apple M1 is often cited for exceptional battery efficiency, the Intel Core Ultra 7 155H is designed with significant efficiency improvements. In real-world usage, M1-based MacBooks generally have a reputation for very long battery life, but modern Windows laptops with the Core Ultra chip can also offer strong all-day performance.
Can I use the same software on both processors?
Not directly. Software is compiled for specific architectures (x86 for Intel, ARM for Apple Silicon). The Apple M1 runs native ARM apps and uses Rosetta 2 to translate many older Intel Mac apps. The Core Ultra 7 runs native Windows x86/x64 applications. Cross-platform software (like web browsers, Adobe Creative Cloud) must have versions built for each platform.
Final Thoughts
The Intel Core Ultra 7 155H and Apple M1 represent two highly competent but distinct paths in modern computing. The Core Ultra 7 brings a modern x86 design with a strong emphasis on AI capabilities and graphical performance to the Windows ecosystem, offering versatility across many laptop brands. The Apple M1, while older, set a high bar for efficiency and integrated performance within a controlled hardware and software environment. The decision is less about which chip is universally “better” and more about which ecosystem—Windows with its broad hardware and software compatibility, or macOS with its optimized integration—better aligns with a user’s existing workflow, software needs, and preferences.
