Intel Core i5 1335U vs Intel Core i7 150U: Full Comparison
Introduction
Choosing the right processor is a key decision when selecting a new laptop. The Intel Core i5-1335U and Core i7-150U are two popular options found in modern ultraportable and mainstream notebooks. This comparison aims to clarify their specifications, architectural similarities, and performance differences. By examining core counts, clock speeds, and feature sets, you can better understand which CPU aligns with your specific usage patterns, whether for general productivity or more intensive workloads.
Architecture and Core Configuration
Both processors share a similar hybrid architecture, combining Performance-cores (P-cores) and Efficient-cores (E-cores). This design aims to optimize for both high-performance bursts and sustained power efficiency.
- Core i5-1335U: This CPU features a 10-core, 12-thread configuration. It consists of 2 P-cores and 8 E-cores. Its base power is 15W, with a maximum Turbo power of 55W.
- Core i7-150U: This processor also uses a 10-core, 12-thread layout with 2 P-cores and 8 E-cores. It operates at the same 15W base power and 55W maximum Turbo power as the i5 model.
The fundamental core and thread count is identical, meaning both chips can handle multitasking and multi-threaded workloads in a similar manner at a basic level.
Performance and Clock Speeds
Performance differentiation primarily comes from clock speeds and cache size. Higher clock speeds allow a processor to complete tasks faster, while more cache can improve efficiency by keeping frequently used data close to the cores.
- Core i5-1335U: The P-cores have a base clock of 1.3 GHz and can turbo up to 4.6 GHz. The E-cores run at a base of 0.9 GHz, turboing to 3.4 GHz. It includes 12MB of Intel Smart Cache (L3 cache).
- Core i7-150U: The P-cores here start at a higher base clock of 1.8 GHz and can reach up to 5.4 GHz. The E-cores have a 1.4 GHz base and a 4.0 GHz turbo frequency. It is equipped with a larger 12MB L3 cache.
The Core i7-150U’s significantly higher turbo frequencies, particularly on the P-cores, give it an advantage in single-threaded and short-burst tasks like application loading, web browsing responsiveness, and light creative work.
Graphics and Integrated Features
Both CPUs include integrated Intel graphics, eliminating the need for a separate graphics card in many laptops. The specific graphics model and its performance can vary.
- Core i5-1335U: Typically integrates the Intel Iris Xe Graphics (80 EU). This GPU is capable of handling display output, video playback, and light gaming or photo editing.
- Core i7-150U: Typically integrates the Intel Graphics (64 EU). While it may have fewer Execution Units (EUs), its performance is influenced by the higher CPU clock speeds and system memory configuration.
Both support modern features like AV1 video decode, HDMI 2.1, DisplayPort 2.1, and up to four simultaneous displays. The actual graphics performance in a laptop also depends heavily on the system’s thermal design and memory (RAM) speed.
Platform and Connectivity
Being from adjacent generations, these processors are built on similar platform technologies with support for the latest connectivity standards.
- Memory Support: Both officially support DDR5 and LPDDR5/x memory types, with maximum speeds often reaching 5200 MT/s and 6400 MT/s respectively. This ensures fast data access for the CPU and integrated graphics.
- Connectivity: They integrate support for Wi-Fi 6E and Bluetooth for wireless connectivity. For wired connections, they support multiple PCIe 4.0 lanes for fast storage (NVMe SSDs) and Thunderbolt 4/USB4, which allows for high-speed data transfer, video output, and charging through a single port.
- AI Acceleration: Both feature Intel’s Gaussian & Neural Accelerator (GNA), which is designed to handle background AI tasks like noise cancellation during calls without consuming significant CPU power.

FAQ
What is the main difference between the Core i5-1335U and Core i7-150U?
The primary differences are found in clock speeds. The Core i7-150U generally features higher maximum turbo frequencies for both its Performance and Efficient cores. It may also support faster memory and include a newer integrated graphics architecture, depending on its specific generation.
Is the Core i7-150U always better than the Core i5-1335U?
Not necessarily in every scenario. For basic tasks like web browsing, document editing, and video streaming, the difference may be minimal. The i7’s advantages become more noticeable in sustained CPU-intensive workloads like video encoding, complex data analysis, or software compilation. The actual performance also depends on the laptop’s cooling system and power limits.
Which processor is more power-efficient?
Both have the same 15W base power design, so their baseline efficiency is similar. Under light loads, they should offer comparable battery life in similarly configured laptops. Under heavy load, the Core i7-150U may consume more power to achieve its higher performance, which could impact battery life if the task is sustained.
Can either CPU handle light gaming?
Yes, both integrated GPUs can handle light gaming, such as esports titles (e.g., League of Legends, CS:GO) or older games at lower settings and resolutions. Performance will vary significantly based on the game’s requirements, system RAM (dual-channel is important), and the laptop’s thermal design.
