The MSI Stealth GS66 is a premium option that excels in high-refresh-rate gaming and has a larger battery, but it is heavier and usually costs more. The Razer Blade 15, on the other hand, offers a higher resolution display with better color accuracy at a slightly lower price and lower weight, making it a balance between portability and performance, although it has shorter battery life. Consider the MSI for longer unplugged usage and intensive gaming, and the Razer if you prioritize a vibrant display and portability for various uses including gaming and creative work. Both have similar processing power and graphics capabilities. Give Feedback

The Razer Blade 15 has a better screen than the MSI Stealth GS66 for general use, engineering and design, content creation, and software development.
For general use, the MSI Stealth GS66 offers a balance of resolution and brightness, making images and text clear and vibrant for everyday tasks, while the Razer Blade 15 excels with a screen that provides even sharper visuals and more luminosity. In tasks such as engineering and design where color accuracy is crucial, both laptops provide good coverage of professional color spaces, but the Razer Blade 15 has a slight edge for professionals seeking the highest fidelity in color reproduction. However, when it comes to gaming and 3D applications, both laptops fall short due to lower refresh rates, which means less fluid motion and slower response times compared to laptops with higher refresh rates designed for these purposes.

The MSI Stealth GS66 offers a higher screen refresh rate for smoother visuals in gaming and 3D applications, while the Razer Blade 15, despite having the same Nvidia RTX 3070 Ti graphics card, provides a higher resolution display, indicating more detailed visuals at the cost of a lower refresh rate.

Florian Glaser | February 2022
"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."

"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."
