The Lenovo IdeaPad 5 15" is more budget-friendly and offers decent general use performance with good battery life, making it suitable for everyday tasks and some light gaming. It's also fairly lightweight and more portable, which is convenient if you travel frequently. On the other hand, the Razer Blade 18 is pricier, but it delivers significantly higher performance for demanding 3D tasks, engineering software, and intensive gaming thanks to its powerful processor and high-end graphics card. Its larger, higher-resolution screen and more robust build are ideal for professionals and gamers who need top-notch visuals and performance, though it's less portable and has a shorter battery life. Choose the Lenovo for casual use and portability at a lower cost, or the Razer if top performance and premium features are your priority, and you're less concerned about cost and portability.

The Razer Blade 18 is very good for gaming and AI, while the Lenovo IdeaPad 5 15" is only fair.
The Lenovo IdeaPad 5 15" has an integrated GPU which is sufficient for casual gaming but lacks the advanced graphics performance of the Razer Blade 18 which is equipped with a high-end Nvidia RTX GPU and a much higher screen refresh rate, both crucial for a superior gaming and 3D experience. Additionally, while the IdeaPad's screen quality is decent, the Razer Blade offers a more vibrant display with better color accuracy and a higher resolution, enhancing the overall visual experience for gaming and graphics-heavy tasks.

The Razer Blade 18 is excellent for engineering and design, while the Lenovo IdeaPad 5 15" is only fair.
The Razer Blade 18 stands out for engineering and design use with its powerful Intel i9 processor, high RAM capacity, and advanced Nvidia RTX GPU, paired with an extensive color-accurate screen, which are very important for such tasks. Conversely, the Lenovo IdeaPad 5 15" has a capable but less potent Ryzen 7 chipset, less RAM, and an integrated GPU which, along with an adequate display, makes it a fair option, with its portability and quiet operating noise being somewhat advantageous.

The Razer Blade 18 has a better screen than the Lenovo IdeaPad 5 15" for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, a laptop with a bright and high-resolution screen provides a pleasing visual experience, which is why the Lenovo IdeaPad 5 offers fair quality with its adequate brightness and resolution, while the Razer Blade 18's very good screen quality comes from its superior brightness and sharper display. For engineering and design, color accuracy and range are crucial; the Razer Blade 18 excels with its wide color gamuts, making it very good for such tasks, whereas the Lenovo IdeaPad 5 is rated fair as it covers less of the color space. When it comes to gaming and 3D, the refresh rate is key for smooth motion; both laptops lack here, with refresh rates that are less suited for high-speed gaming, affecting their poor quality rating in this regard.

"The Lenovo IdeaPad 5 is convincing due to its long battery life. The device scores points especially with its large battery and long battery runtimes combined with its low consumption. The CPU and GPU perform in the test as one would expect, and in line with what was familiar from the somewhat smaller 14-inch sister model, the Lenovo IdeaPad 5 14."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
