Dell Inspiron 15 3525 vs Lenovo Legion Slim 7 15.6"

The Lenovo Legion Slim 7 outperforms the Dell Inspiron 15 3525 in general use due to its superior processing power, greater RAM for multitasking, higher screen quality with better brightness and color coverage, and longer battery life, despite being slightly heavier which affects portability. The Dell Inspiron is nevertheless suitable for basic tasks and has good heat management, plus excellent fan noise control, but it falls behind in performance and display compared to the Lenovo, making the latter a more rounded choice for a variety of tasks.

The Dell Inspiron 15 3525, while suitable for casual gaming, has a less powerful GPU and a standard screen refresh rate, which may not deliver the smoothest gaming or 3D experience. The Lenovo Legion Slim 7 has a higher-performing GPU and a faster screen refresh rate, providing a more immersive and responsive experience for gaming and 3D applications, despite potentially having a higher price and lower battery life due to more demanding hardware.

The Lenovo Legion Slim 7 with its more robust AMD Ryzen 7 processor, double the RAM, and superior Nvidia RTX graphics card, provides higher performance for engineering and design tasks, further complemented by a brighter and more color-accurate screen than the Dell Inspiron 15 3525. However, the Dell offers a fair balance of performance with its AMD Ryzen 5 processor and integrated graphics, proving adequate for less demanding engineering use at a possibly lower price point and better portability due to its lighter weight.
