Choosing between the Lenovo Legion Slim 5 and the Razer Blade 15 depends on your priorities. If you're looking for a more budget-friendly option that still provides solid performance for general use and gaming, the Legion Slim 5 with an AMD processor and RTX 4060 graphics card is a good choice. However, it is heavier and bigger than the Blade 15. On the other hand, the Razer Blade 15, with its Intel i7 processor and RTX 3070 Ti graphics card, offers a higher resolution display, better screen color accuracy, and is more portable due to its lighter weight and smaller size, but it comes at a higher price. The Razer also has a better build quality, but the Legion offers longer battery life for typical use. Both have a 16GB RAM and multiple USB-C ports, but the Legion has a number pad while the Blade does not. If your work involves color accuracy or you need a more portable and premium laptop, and you don't mind spending more, the Razer Blade 15 is the more suitable option. Give Feedback

The Razer Blade 15 and Lenovo Legion Slim 5 are both very good for engineering and design, though the Razer Blade 15 is somewhat better.
The Lenovo Legion Slim 5 and Razer Blade 15 are both adept for engineering and design tasks due to their powerful CPUs, ample RAM, and high-quality discrete GPUs, which are critical for processing complex tasks and renderings. While Lenovo's device boasts a sizeable screen and considerable battery capacity, the Razer Blade 15 offers a higher resolution display for finer detail, coupled with superior portability and better speaker quality, but the Lenovo, with a quieter operating noise, caters better to noise-sensitive environments.

The Razer Blade 15 has a better screen than the Lenovo Legion Slim 5 for general use, gaming and AI, engineering and design, content creation, and software development.
When considering general use such as browsing or watching videos, both the Lenovo Legion Slim 5 and the Razer Blade 15 offer screens with adequate resolution and brightness, but the Razer Blade 15 has a slight edge with its vibrant display. For engineering and design work, which demands precise color representation, the Razer Blade 15's coverage of color gamuts like DCI-P3 and Adobe RGB ensures more accurate color rendering than the Lenovo Legion Slim 5. However, for gaming and 3D applications where smooth motion is key, both laptops fall short due to their lower refresh rates, despite having decent resolution and panel types.

Although they have very similar scores, PerfectRec considers Razer Blade 15 to be very good for gaming and AI, while the Lenovo Legion Slim 5 is good.
The Razer Blade 15 outperforms the Lenovo Legion Slim 5 in gaming and 3D tasks primarily due to its more powerful GPU and smoother visuals enabled by a higher screen refresh rate; although the Lenovo has a solid GPU and decent refresh rate, it falls short compared to the Razer's capacity to deliver very high-quality graphics quickly. While both have competent CPUs and good screen quality, these factors are less critical than the GPU and refresh rate when comparing their gaming and 3D capabilities.

PCMag
Mark Knapp | August 2023
"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."

Allen Ngo | March 2022
"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."
