About Hardware Intel Core i7 720QM
Released in 2009 as part of the Clarksfield (Nehalem) architecture, the Intel Core i7-720QM is a high-end mobile processor aimed at gaming laptops and workstations. It has 4 cores and 8 threads, with a base clock speed of 1.6 GHz, which can increase to 2.8 GHz using Intel Turbo Boost.
With 45nm fabrication, this processor has a TDP of 45W, which is quite high for laptop standards. Because it uses Hyper-Threading, it can handle eight threads simultaneously, improving performance in multi-threaded applications such as video rendering and editing.
In terms of graphics, the i7-720QM does not have an integrated GPU, so laptops using it must have a discrete graphics card for display output.
Compared to modern processors, the i7-720QM's performance is quite behind, especially in power efficiency. However, for legacy systems still using this processor, its performance is still sufficient for basic tasks and some heavy applications with proper optimization.

About Hardware Intel Celeron B815
Released in 2012 as part of the Sandy Bridge family, the Intel Celeron B815 is an entry-level mobile processor aimed at cost-effective laptops. It has 2 cores and 2 threads, with a clock speed of 1.6 GHz without Turbo Boost or Hyper-Threading support.
With 32nm fabrication, the Celeron B815 has a TDP of 35W, which is quite high for a processor of its class. For graphics, the processor uses Intel HD Graphics 2000, which has a base clock speed of 650 MHz and can increase up to 1 GHz in Boost mode.
In daily use, the Celeron B815's performance is sufficient for light tasks such as browsing, document processing, and 720p video playback. However, since it lacks technologies such as Hyper-Threading and Turbo Boost, its performance is quite limited for multitasking and heavy applications.
