The Lenovo IdeaPad 5 15" is a budget-friendly laptop that is lighter and has a decent battery life for general use, making it good for portability and everyday tasks. It includes a number pad and a backlit keyboard. In contrast, the Razer Blade 17, with its high-end price tag, offers superior performance suited for intensive gaming, 3D rendering, and engineering tasks thanks to its powerful processor and high-end graphics card. It also has a larger, higher-resolution display, which is not touchscreen but offers a higher refresh rate, ideal for fast-motion visuals. However, it is heavier and has a shorter battery life, which can be a downside for those needing mobility. Both have backlit keyboards and multiple USB-C ports, but only the Razer Blade 17 supports Thunderbolt connections. Give Feedback

The Razer Blade 17 is excellent for engineering and design, while the Lenovo IdeaPad 5 15" is only fair.
The Lenovo IdeaPad 5 15" has less RAM, a less powerful integrated GPU, and a lower quality screen compared to the Razer Blade 17, which affects its engineering and design performance; the Razer Blade 17, although less portable due to its larger size and heavier weight, excels with a superior CPU, a high-end discrete GPU, more RAM, and a better quality display, making it exceptionally suitable for demanding engineering tasks. While the Lenovo may appeal for routine tasks given its decent portability and battery life, the Razer's tradeoff in heft and shortened battery duration is a worthwhile exchange for its vastly improved performance and screen quality in professional settings.

Marcus Schwarten | August 2021
"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."

"Our test configuration of the Blade 17 targets gamers and creative professionals. A Core i9-12900H processor, GeForce RTX 3080 Ti Laptop GPU (175 watts TGP after the BIOS update, 16 GB of VRAM), and 32 GB of working memory equip the laptop for video processing, rending, and 4k gaming at the highest level. In addition, a fast PCIe-4 SSD (1 TB) ensures short load and storage times. With the Blade 17 (Early 2022), Razer delivers a successful and powerful work device for creative professionals. But this also has its price."
