The Razer Blade 15 offers a balance of power and portability, being lighter and less costly than the Razer Blade 18, making it a solid choice for general use and gaming. It features a slightly smaller screen size, lower battery life, and less RAM than the Blade 18, but it still delivers high performance for most tasks and games. However, if you require maximum performance for tasks such as 3D rendering, machine learning, or engineering, the Razer Blade 18, with its more powerful processor, additional RAM, and larger display may be more suitable despite the higher price and decreased portability due to its increased size and weight. Both laptops have similar storage capabilities, high-quality keyboards, and are built to handle intensive gaming. Give Feedback

The Razer Blade 18 is very good for general use, while the Razer Blade 15 is good.
The Razer Blade 18 boasts a higher-end CPU and double the RAM of the Razer Blade 15, alongside a larger and brighter screen, which enhances its performance and screen quality for general use, but its increased size and weight reduce its portability and it offers slightly less battery life. Conversely, the Razer Blade 15 is more portable due to its smaller size and lighter weight, and slightly longer battery life, but it has a less powerful CPU and half the RAM, which may affect multitasking and intensive applications despite its good screen quality.

The Razer Blade 18 has a better screen than the Razer Blade 15 for general use, gaming and AI, engineering and design, content creation, and software development.
When considering general use, the Razer Blade laptops' panel type, high resolution, and brightness contribute to their very good screen quality, ensuring a crisp and vivid display that's easy to view in various lighting conditions. For engineering and design tasks, their screens also excel due to the wide color gamuts they cover, providing a range of colors necessary for precision work. However, for gaming and 3D applications, their lower refresh rates compared to specialized gaming screens make them less suitable, as they may not deliver as fluid motion, which is crucial for fast-paced visuals.

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."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
