Intel Core I7-1255u Vs Intel Core I5-1135g7

The Intel Core i7-1255U and Intel Core i5-1135G7 are two powerful laptop processors that offer excellent performance for everyday tasks and demanding applications. In this blog post, we will compare these two CPUs in-depth, exploring their key features, performance, and efficiency to help you make an informed decision.

Architecture and Cores

The Intel Core i7-1255U is based on Intel’s 12th-generation Alder Lake architecture, while the Core i5-1135G7 is based on the 11th-generation Tiger Lake architecture. The i7-1255U features a hybrid architecture with 10 cores: 2 Performance (P) cores and 8 Efficient (E) cores. The i5-1135G7, on the other hand, has 4 cores and 8 threads.

Performance

In terms of performance, the Core i7-1255U has a clear advantage over the i5-1135G7, particularly in multi-threaded applications. The P-cores provide significant performance boosts for tasks such as video editing, 3D rendering, and software development. The E-cores, while not as powerful as the P-cores, can handle background tasks efficiently, freeing up the P-cores for more demanding applications.

Graphics

Both processors feature integrated graphics, but the i7-1255U has a slightly more powerful Intel Iris Xe Graphics G7 with 96 Execution Units (EUs) compared to the Intel Iris Xe Graphics G7 with 80 EUs in the i5-1135G7. This difference is noticeable in graphics-intensive applications such as gaming and video editing, where the i7-1255U provides smoother performance.

Efficiency and Battery Life

The Core i7-1255U is built on a more advanced 10nm process compared to the 11nm process of the i5-1135G7. This results in improved energy efficiency, allowing the i7-1255U to deliver similar performance while consuming less power. As a result, laptops equipped with the i7-1255U may offer longer battery life.

Features and Support

Both processors support Thunderbolt 4, Wi-Fi 6, and Bluetooth 5.2. However, the i7-1255U also supports PCIe 4.0, which enables faster data transfer speeds with compatible storage devices. Additionally, the i7-1255U has Intel vPro support, which provides enhanced security and manageability features for business laptops.

Pricing and Availability

The Intel Core i7-1255U is typically found in higher-end laptops and is priced at a premium compared to the Core i5-1135G7. The i5-1135G7 is more widely available in mid-range laptops and offers a more budget-friendly option.

Which One is Right for You?

The choice between the Intel Core i7-1255U and Intel Core i5-1135G7 depends on your specific needs and budget. If you prioritize performance and need a laptop for demanding applications, the i7-1255U is the better choice. However, if you are looking for a more affordable option that still provides solid performance for everyday tasks and light gaming, the i5-1135G7 is a great choice.

Beyond the Comparison: Other Considerations

1. Laptop Design: The i7-1255U is typically found in thinner and lighter laptops due to its improved energy efficiency. The i5-1135G7 may be more common in thicker laptops with better cooling capabilities.

2. RAM and Storage: Ensure that you choose a laptop with sufficient RAM and storage capacity to meet your needs.

3. Operating System: Both processors support Windows 11 and Windows 10 operating systems.

4. Brand and Reliability: Consider the reputation and reliability of the laptop brand before making a purchase.

5. Warranty and Support: Look for laptops with comprehensive warranties and support options to protect your investment.
