For tasks involving 3D rendering, machine learning, or gaming, the Lenovo Legion Slim 5 stands out with its dedicated Nvidia graphics card and more RAM, which greatly enhance performance for these demanding applications, although it has lower portability due to its larger size and weight. Both laptops fall in a similar price range, but the ASUS may often be found slightly less expensive. Give Feedback

The ASUS Zenbook 14X OLED has a better screen than the Lenovo Legion Slim 5 for general use, gaming and AI, and engineering and design.
For general use, the ASUS Zenbook 14X OLED excels with its vibrant OLED panel that offers deep blacks and high resolution, which provides a sharp and bright display, while the Lenovo Legion Slim 5's display, although still good, doesn't offer the same level of color contrast or brightness. In engineering and design tasks, the Zenbook's wider color gamut presents more accurate colors, crucial for professionals who need precise color representation, but the Legion Slim 5's color reproduction, while less accurate, may suffice for less demanding work. However, for 3D and gaming activities, the Zenbook's display, despite its quality, falls short due to a lower refresh rate, which means less fluid motion, while the Legion Slim 5 also lacks a high refresh rate, making both less ideal for these fast-paced tasks.

The Lenovo Legion Slim 5 and ASUS Zenbook 14X OLED are both good for general use.
The ASUS Zenbook 14X OLED offers solid general use capabilities, emphasizing portability with its lower weight and smaller dimensions, alongside a high-quality OLED touchscreen for vivid colors and contrast; however, the battery life is shorter compared to the Lenovo Legion Slim 5, which compensates with a larger, higher-refresh rate screen, more memory for multitasking and a dedicated graphics card, making it better suited for more demanding tasks but at the expense of being heavier and less portable.

Although they have very similar scores, PerfectRec considers Lenovo Legion Slim 5 to be very good for engineering and design, while the ASUS Zenbook 14X OLED is good.
The ASUS Zenbook 14X OLED has an OLED screen with high brightness and color accuracy making it suitable for detailed design work, but it is less capable in computational tasks due to its integrated GPU and lower RAM compared to the Lenovo Legion Slim 5, which has a dedicated high-performance GPU and double the RAM, making it superior for engineering tasks requiring intensive graphics processing, yet it's heavier, making it less portable. The Lenovo's premium screen quality doesn’t match the ASUS's OLED display, but its better thermal management and quieter operation noise could make for a more comfortable working environment, especially during long sessions.

Matthew Buzzi | September 2023
"While one of the more budget-friendly configurations of the Asus Zenbook 14X OLED may make a compelling case as a top value pick, it’s difficult to be disappointed with the more expensive model we reviewed here. At its core, for all models, it’s a luxury-built laptop with extreme portability and a gorgeous OLED display. Our unit rocks with a snappy Core i9 processor for getting real work done, and the discrete GPU—even if it has a clear power ceiling—is a bonus for creative pros."

"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
