About Hardware Intel Core i7 720QM

The Intel Core i7-720QM, launched in Q3 2009, was one of the first mobile quad-core processors to feature Intel's Nehalem microarchitecture, specifically the Clarksfield variant. Targeted at high-performance laptops, such as gaming machines and mobile workstations, the i7-720QM brought 4 physical cores and 8 threads to the mobile platform, thanks to Hyper-Threading Technology providing a significant boost in multi-threaded workloads like video editing, 3D rendering, and other professional-grade applications. The processor runs at a base clock speed of 1.6 GHz, but it can dynamically increase up to 2.8 GHz using Intel Turbo Boost, depending on thermal headroom and power availability.

Manufactured using a 45nm process, the i7-720QM has a TDP of 45W, which is quite high by today's mobile CPU standards. This thermal demand necessitated more robust cooling solutions in laptops that featured the chip. Unlike modern CPUs, the i7-720QM does not come with integrated graphics, which means systems based on this processor require a dedicated GPU often from AMD or NVIDIA for graphics processing and display output. As such, it was typically paired with mid-to-high-end discrete graphics cards in its time, making it a solid choice for gaming and multimedia laptops in the late 2000s and early 2010s.

While the Core i7-720QM was a powerhouse during its release, its performance and efficiency are significantly outpaced by modern CPUs built on smaller nodes and with higher IPC (Instructions Per Clock). Nevertheless, legacy laptops using the i7-720QM can still be viable for basic computing tasks like web browsing, document editing, or watching videos especially if paired with an SSD upgrade and increased RAM. Users running Windows 10 on such systems may experience some limitations, but with proper optimization and lightweight software, the CPU can still deliver a usable experience in non-demanding environments.

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.
