The Razer Blade 15 offers superior gaming, 3D rendering, and machine learning performance but comes at a higher price and is less portable due to its larger size and heavier weight. On the other hand, the Lenovo ThinkBook 13s is more affordable, lightweight, and features a touchscreen. It's better suited for general use and offers longer battery life. However, the ThinkBook's performance in demanding tasks like gaming and engineering is not as high as the Razer's. Your choice depends on whether you prioritize high-end performance and gaming capabilities, or portability and cost efficiency with sufficient performance for everyday tasks. Give Feedback

The Razer Blade 15 is very good for gaming and AI, while the Lenovo ThinkBook 13s is only fair.
The Razer Blade 15 is better suited for gaming and 3D applications due to its superior Nvidia RTX 3070 Ti GPU and a higher screen refresh rate of 240 Hz, which can render more frames per second for smoother visuals, whereas the Lenovo ThinkBook 13s, with its integrated Intel Iris Xe graphics and a standard refresh rate of 60 Hz, offers less graphical power and slower screen updates.

The Razer Blade 15 is very good for engineering and design, while the Lenovo ThinkBook 13s is good.
The Razer Blade 15 excels in engineering and design tasks due to its powerful dedicated GPU (RTX 3070 Ti), a high-quality larger screen with a high refresh rate and good color coverage, as well as a strong CPU; however, it is less portable and has a shorter battery life. In contrast, the Lenovo ThinkBook 13s with an integrated GPU provides sufficient capabilities for engineering and design, a high-resolution display with a taller aspect ratio suited for productivity, longer battery life, and notably better portability, but it lacks the advanced graphics performance of the Razer Blade 15.

The Razer Blade 15 has a better screen than the Lenovo ThinkBook 13s for general use, gaming and AI, engineering and design, and content creation.
The Razer Blade 15 has a vibrant, high-resolution display that makes it excellent for general use and tasks like photo editing or design work that require accurate colors. However, its lower refresh rate detracts from the gaming and 3D experience where smooth motion is crucial. The Lenovo ThinkBook 13s offers sufficient resolution and color accuracy for daily tasks and professional design, but like the Razer, it lacks the high refresh rate that gamers and 3D artists need for optimal performance.

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."

"The best thing about the ThinkBook 13S is that it’s a good deal. Business buyers looking for ThinkPad-level performance and software without ThinkPad pricing will probably find the ThinkBook a solid option. While nothing about it is really spectacular, it’s certainly unusual to see the ThinkBook’s screen resolution at a sub-$1,000 price, and its performance will be more than adequate for most office tasks. The generous port selection, 16:10 aspect ratio, physical webcam shutter, and clear audio are certainly icing on the cake."
