The Lenovo IdeaPad 3 15" offers affordability and is sufficient for general use like browsing, office work, and streaming media. In contrast, the Razer Blade 15 has a higher price tag but provides better performance suitable for gaming, 3D modeling, or intensive engineering tasks. You'll also find a clearer and more vibrant display on the Razer, which may be important if you're into content creation or media consumption. The trade-off for the Razer's performance is less portability due to its weight and often shorter battery life when compared to the Lenovo, which is lighter and typically offers longer battery life for on-the-go use. If cost isn't the primary concern and you need a high-performance machine, the Razer Blade is an excellent choice; otherwise, for everyday tasks, the Lenovo IdeaPad 3 15" is a budget-friendly option that covers all the basics.

The Razer Blade 15 is good for general use, while the Lenovo IdeaPad 3 15" is only fair.
The Lenovo IdeaPad 3's Intel i3 processor and 8GB of RAM are adequate for everyday tasks, but the Razer Blade 15's more powerful Intel i7 processor and 16GB of RAM offer a superior experience for more demanding applications. While the IdeaPad provides a fair battery life and a high portability score, its TN screen with lower resolution may not be as visually appealing as the Razer's high-resolution IPS display, which together with excellent speaker and build quality offers an overall better performance for general use despite being less portable.

The Razer Blade 15 is very good for gaming and AI, while the Lenovo IdeaPad 3 15" is poor.
The Lenovo IdeaPad 3 has an Intel UHD Xe G4 graphics unit and a screen refresh rate of 60Hz, which may not provide the graphics power and fluidity needed for gaming and 3D applications. In contrast, the Razer Blade 15 comes equipped with a high-performance Nvidia RTX 3070 Ti graphics card and a 240Hz screen refresh rate, offering a smooth and visually immersive experience suitable for intensive gaming and 3D rendering.

The Razer Blade 15 is very good for engineering and design, while the Lenovo IdeaPad 3 15" is poor.
The Lenovo IdeaPad 3 15" has a basic Intel i3 processor, integrated graphics, and a TN panel with a low resolution, limiting its suitability for resource-intensive engineering tasks and high-quality visual work. On the other hand, the Razer Blade 15 is equipped with a high-performance Intel i7 processor, a powerful Nvidia RTX GPU, and an IPS display with higher resolution and color accuracy, making it far superior for such demanding applications.

The Razer Blade 15 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 IdeaPad 3's screen may not provide the clarity and brightness you want for everyday tasks or multimedia enjoyment, and its limited color range can hinder work involving precise color work such as graphic design or engineering simulations. The Razer Blade 15 offers a more vibrant and accurate display, ensuring your designs and projects look as intended with a wide array of colors, which is essential for professional engineering and design work. However, for gaming and 3D applications that demand fluid motion, the Razer Blade 15 might disappoint as it possibly lacks the high refresh rate that ensures smooth, flicker-free visuals during fast-paced scenes.

"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."

"The 2022 Blade 15 offers roughly 15 to 25 percent faster graphics performance and 20 percent faster CPU performance over last year's Core i7-11800H and RTX 3080 model. Thankfully, the system doesn't need to run noticeably louder or warmer to achieve faster results, but both power consumption and battery life take a hit. The higher consumption in particular appears to be a trend amongst many 12th gen Core laptops including the Schenker Uniwill Technology GM7AG8P or MSI Vector GP66 when compared to their previous generation counterparts. We're also glad to not see below-average CPU performance which was the case for the 10th gen Core i7-10875H model."
