Intel Core i5 1335U vs AMD Ryzen 5 8540U: Full Comparison
Introduction
Choosing the right processor is a key decision when selecting a modern laptop for productivity, content consumption, and light creative work. This comparison examines two popular options in the efficient 15-watt class: Intel’s Core i5-1335U from its 13th Gen Raptor Lake lineup and AMD’s Ryzen 5 8540U, part of the newer “Hawk Point” series. We will analyze their architectures, core configurations, performance profiles, and integrated graphics to provide a clear understanding of their respective strengths and typical use cases.
Architecture and Core Configuration
The fundamental design philosophies of these two chips differ significantly, impacting how they handle workloads.
- Intel Core i5-1335U: This processor utilizes a hybrid architecture with two types of cores: 2 Performance-cores (P-cores) and 8 Efficient-cores (E-cores), for a total of 10 cores and 12 threads. The P-cores handle demanding single and lightly-threaded tasks, while the E-cores manage background processes and multi-threaded workloads efficiently.
- AMD Ryzen 5 8540U: Built on a “monolithic” Zen 4 architecture, this chip features 6 identical CPU cores and 12 threads. All cores are designed for high performance and power efficiency. It is part of AMD’s Hawk Point series, which is an update focusing on its AI capabilities and integrated graphics.
This means the i5-1335U is structured to dynamically allocate tasks, whereas the Ryzen 5 8540U uses a more traditional, uniform core design.
CPU and Application Performance
Performance can vary based on the specific task, system design, and cooling solution.
- Single-Core Performance: The Intel Core i5-1335U, with its higher peak clock speeds on P-cores (up to 4.6 GHz), typically holds an advantage in applications that rely on single-threaded performance, such as certain aspects of web browsing, office applications, and legacy software.
- Multi-Core Performance: Despite having more total cores, the i5’s E-cores are less powerful individually. The Ryzen 5 8540U’s 6 full Zen 4 cores often deliver strong and consistent performance in multi-threaded applications like video conferencing, compiling code, or handling multiple applications simultaneously. The performance here is generally quite close and can depend on the thermal design of the laptop.
Integrated Graphics and Gaming
This is one of the most distinct areas of differentiation between the two processors.
- Intel Core i5-1335U: Features Intel Iris Xe Graphics (80 Execution Units). It is a capable iGPU for basic photo editing, video playback, and very light gaming at low settings. Performance is adequate for everyday tasks.
- AMD Ryzen 5 8540U: Equipped with AMD Radeon 740M graphics based on the RDNA 3 architecture. This integrated GPU is significantly more powerful than Intel’s Iris Xe, offering noticeably better performance in casual gaming, light esports titles, and GPU-accelerated creative applications. It is often considered the stronger choice for users without a discrete graphics card who still want some graphical capability.
Power Efficiency and Battery Life
Both chips are rated at a 15-watt base TDP (configurable by laptop manufacturers), making them suitable for thin-and-light devices.
- Platform Efficiency: AMD’s Zen 4 architecture, fabricated on a 4nm process, is generally associated with excellent power efficiency, particularly in lighter workloads. This can often translate to longer battery life in comparable laptop designs when performing typical tasks like web browsing and video playback.
- Intel’s Hybrid Approach: The E-cores in the i5-1335U are designed to sip power during low-activity periods, which can also contribute to good battery life. Real-world battery longevity is heavily influenced by the laptop’s display, battery capacity, and software optimization, making direct comparisons difficult without specific laptop models.
Platform and Feature Support
Both platforms offer modern connectivity and features, with some generational differences.
- Memory Support: Both processors support DDR5 and LPDDR5/x memory, ensuring fast system responsiveness.
- Connectivity: They typically include support for Wi-Fi 6E and Bluetooth 5.3. The Ryzen 5 8540U platform may more commonly feature newer standards like USB4, which is similar to Thunderbolt 4 (a strength of Intel platforms).
- AI and NPU: The Ryzen 5 8540U includes a dedicated Neural Processing Unit (NPU) for accelerating AI workloads, which is becoming more relevant for features like background blur in video calls and certain creative filters. The Intel i5-1335U relies on CPU and GPU for AI tasks.

Frequently Asked Questions (FAQ)
What is the main performance difference between the i5-1335U and Ryzen 5 8540U?
The main difference typically lies in the integrated graphics and architectural approach. The i5-1335U often has an edge in bursty, single-threaded tasks, while the Ryzen 5 8540U generally provides stronger graphics performance for light gaming and benefits from a dedicated NPU for AI tasks.
Which processor is generally better for battery life?
While real-world results depend heavily on the laptop’s overall design, the AMD Ryzen 5 8540U, built on a 4nm process, is often associated with very good power efficiency in light-to-moderate workloads, which can contribute to longer battery life in many usage scenarios.
Can either of these CPUs handle light gaming?
Yes, both can handle very light and older titles. However, the AMD Ryzen 5 8540U with its Radeon 740M graphics is significantly more capable for casual gaming and can run many esports titles at playable frame rates at 1080p with low-to-medium settings, whereas the Intel Iris Xe graphics are more limited.
Does the Core i5-1335U have an NPU like the Ryzen 5 8540U?
No, the Intel Core i5-1335U does not include a dedicated Neural Processing Unit (NPU). It handles AI-accelerated tasks using its CPU cores and integrated graphics. The Ryzen 5 8540U includes a dedicated NPU as part of AMD’s Ryzen AI platform.
Final Thoughts
The Intel Core i5-1335U and AMD Ryzen 5 8540U represent two competent approaches to modern mobile computing. The choice between them often comes down to prioritizing specific strengths. If your usage leans heavily on applications that benefit from strong single-core performance and you are in an ecosystem that favors Thunderbolt connectivity, the i5-1335U is a solid choice.
