About Hardware Intel Core i5 1135G7
The Intel Core i5-1135G7 is a quad-core mobile processor introduced in late 2020 as part of Intel’s 11th generation Tiger Lake lineup. Designed for thin and light laptops, this CPU delivers a strong balance of performance, power efficiency, and modern features, making it a popular choice for both casual users and professionals. Featuring 4 cores and 8 threads through Hyper-Threading Technology, it operates at a base clock of 2.4 GHz and can reach up to 4.2 GHz with Intel Turbo Boost, ensuring smooth multitasking and snappy responsiveness for day-to-day applications.
Built using Intel’s advanced 10nm SuperFin process, the i5-1135G7 offers improved efficiency and thermal performance over previous 14nm generations. With a configurable TDP ranging from 12W to 28W, OEMs can adjust the performance envelope depending on the device’s thermal design. The standout feature of this processor is its integrated Intel Iris Xe Graphics, equipped with 80 Execution Units and a dynamic frequency of up to 1.3 GHz. Compared to older Intel UHD Graphics, Iris Xe brings a massive leap in performance, capable of handling casual gaming, 4K video playback, and GPU-accelerated workloads like video rendering or image editing.
In benchmark tests such as Cinebench R23, the i5-1135G7 scores around 5661 points (multi-core) and 1334 points (single-core), showcasing excellent performance for a low-power chip. These scores reflect its capability to handle modern productivity software, web-based workflows, and even creative tools like Adobe Photoshop or Premiere Pro though for heavier workloads, a higher-end CPU may still be recommended.
Real-world performance testing was done on a Lenovo IdeaPad Slim 3i 14ITL6, a budget-to-midrange laptop equipped with 12GB DDR4 3200MHz dual-channel memory (8+4 configuration). This setup, combined with Windows 10 and Windows 11 22H2, allows the i5-1135G7 to fully utilize its integrated GPU and high-speed memory interface for a snappy and responsive user experience.
Whether you're a student, a professional, or a casual user looking for a capable, energy-efficient processor, the Intel Core i5-1135G7 stands out as one of the best value choices in the ultrabook category.

About Hardware Intel Celeron B815
The Intel Celeron B815, released in 2012, is an entry-level mobile processor based on the Sandy Bridge architecture. Designed for budget laptops, it features 2 cores and 2 threads with a fixed clock speed of 1.6 GHz. The processor does not support Turbo Boost or Hyper-Threading, limiting its multitasking capabilities.
Manufactured using 32nm process technology, the Celeron B815 has a TDP of 35W, which is relatively high for a low-end mobile CPU. This higher thermal output typically results in shorter battery life and more heat generation compared to modern low-power processors.
For graphics, the processor is equipped with Intel HD Graphics 2000, which runs at a base frequency of 650 MHz and can boost up to 1.0 GHz. While not suitable for gaming, this integrated GPU handles basic visual tasks like 720p video playback, simple animations, and light graphical workloads adequately.
In everyday usage, the Celeron B815 performs best with lightweight applications such as web browsing, word processing, and playing standard-definition videos. However, it struggles with modern operating systems, multitasking, and heavier workloads due to its limited core/thread count and lack of advanced CPU features.
