About Hardware Intel Celeron N2815

The Intel Celeron N2815 is a power-efficient processor released in 2013 as part of the Bay Trail-M family, aimed at entry-level laptops and lightweight computing devices. It has 2 cores and 2 threads with a base speed of 1.86 GHz that can increase to 2.13 GHz thanks to Intel Burst Performance technology. Built using a 22nm fabrication process, the N2815 comes with a TDP of only 7.5 watts, making it one of Intel's most efficient processors in terms of power consumption for the low-end class. This makes it very suitable for portable devices such as netbooks or mini laptops that prioritize battery life over high performance.

On the graphics side, the Intel Celeron N2815 is equipped with an integrated Intel HD Graphics (Bay Trail) GPU that runs at a base frequency of 313 MHz and can reach up to 756 MHz under certain conditions. This GPU is capable enough to run desktop displays smoothly, and supports 720p video playback. However, for heavy graphics tasks such as playing modern 3D games, video editing, or graphic design, this GPU is clearly not capable. Its use is more suitable for everyday computing such as opening documents, browsing the internet, playing standard videos, and running light office applications.

In terms of overall performance, the Celeron N2815 is sufficient for running light operating systems such as Windows 7 or light-based Linux distributions such as Lubuntu or Linux Mint XFCE. However, due to its simple architecture and low single-threaded performance, users may experience limitations when running multiple applications at once or when opening software that requires higher computing power. In tests using an Asus X200MA laptop with 2GB DDR3 dual channel RAM and Windows 7 operating system, performance was good enough for basic use, although it was slow when running modern applications or multitasking.

Overall, the Intel Celeron N2815 is a decent processor for light computing needs with low power consumption and an economical price, but it is not recommended for heavy productivity tasks or long-term use on modern operating systems.

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.
