When deciding between the Lenovo IdeaPad 3 and the Razer Blade 18, consider that the Lenovo is more budget-friendly and suitable for everyday tasks with moderate performance needs, such as web browsing, document editing, and media consumption. Its lighter weight also enhances portability, although its lower-resolution screen and modest hardware mean it may struggle with more demanding applications. In contrast, the Razer Blade 18 is priced at a premium, offering powerful performance for intensive tasks like 3D rendering, machine learning, gaming, and engineering software. Its larger, high-resolution screen provides a better viewing experience, but the device is heavier, potentially impacting portability. Additionally, the higher specifications may also mean a decrease in battery life compared to the Lenovo. Give Feedback

The Razer Blade 18 is very good for general use, while the Lenovo IdeaPad 3 15" is only fair.
The Lenovo IdeaPad 3, with a basic Intel i3 processor, less RAM, and a lower-resolution TN screen, is just adequate for everyday tasks and compromises on screen quality and performance for affordability and better portability. Conversely, the Razer Blade 18 offers a high-end Intel i9 processor, more RAM, and a superior IPS display, enhancing both performance and screen quality at the expense of higher cost, reduced portability, and shorter battery life.

The Razer Blade 18 has a better screen than the Lenovo IdeaPad 3 15" for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo IdeaPad 3's screen may not provide the crisp, vibrant visuals you'd want for any purpose due to its lower resolution and brightness, which can result in a less engaging experience whether you're browsing the web, working on projects, or playing games. The Razer Blade's superior resolution and brightness make it ideal for tasks requiring precise detail and color accuracy, such as photo editing or drafting, but its lower refresh rate compared to specialized gaming laptops means that fast-paced games may not look as smooth. While both laptops have screens with limitations depending on the task, the Razer Blade stands out for design work, and the Lenovo IdeaPad might suffice for users less concerned with screen fidelity.

"The Lenovo IdeaPad 3 is an enduring office notebook with a powerful Ryzen APU. Lenovo's office all-rounder easily handles office and internet applications as well as modest games - the Ryzen 5 5625U APU and 16 GB of RAM make this possible. The CPU and GPU can work at consistently high clock rates. The emission values are okay, but the noise emissions should be lower under medium to full load. The relatively light notebook (approx. 1.6 kg) achieves practical battery runtimes of about 10 to 11 hours."

"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."
