If you prioritize performance for tasks such as 3D rendering, machine learning, or intensive gaming, the ASUS ROG Strix G18 with its top-tier graphics and processor will serve you better. However, it's heavier and has a shorter battery life, making it less ideal for carrying around. The Razer Blade 15 is more portable with a lighter build and slightly longer battery life. Its performance is also strong, though not as powerful as the ASUS, it's still suitable for gaming and general work. Both come at upper midrange prices, so your choice depends on whether portability or raw power is more important for your needs. Give Feedback

The ASUS ROG Strix G18 has a better screen than the Razer Blade 15 for general use, gaming and AI, engineering and design, software development, and content creation.
When considering laptops for general use, both the ASUS ROG Strix G18 and the Razer Blade 15 have high-resolution displays and brightness levels that make text sharp and content vivid, providing a pleasant viewing experience for everyday tasks like browsing and video streaming. For engineering and design professionals, who need precise color representation, both laptops offer displays with wide color gamuts, ensuring that the colors in their projects appear accurate and consistent, which is crucial for professional work. However, for gaming and 3D, the refresh rate is key to smooth motion and responsiveness; in this aspect, both laptops fall short, providing a less optimal experience where fast-paced visuals might appear less fluid, affecting gameplay and 3D rendering.

Florian Glaser | March 2023
"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."

"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."
