For general use with high portability and battery life, the Lenovo ThinkPad Z13 offers a solid balance, being lighter and having a longer battery life. It's also less expensive but has enough performance for everyday tasks and lighter engineering work. The Razer Blade 15, while pricier and heavier, offers significantly higher performance for 3D rendering, machine learning, and gaming thanks to its powerful graphics card. It's better suited for intensive tasks but at the cost of lower battery life and portability. Evaluate your need for performance versus portability and battery life to make the best choice for you.

The Razer Blade 15 is very good for engineering and design, while the Lenovo ThinkPad Z13 is good.
The Lenovo ThinkPad Z13 is suitable for engineering and design, with solid CPU and GPU capabilities for such tasks, and its lighter weight and smaller screen make it more portable than the Razer Blade 15, which, however, offers a more powerful GPU, higher screen resolution, and larger screen size, making it very good for these purposes but less portable due to its heavier build. While both have quality displays and sufficient RAM, the Razer's stronger performance components give it an edge for more demanding engineering and design applications, at the cost of decreased portability and increased weight.

The Razer Blade 15 has a better screen than the Lenovo ThinkPad Z13 for general use, gaming and AI, engineering and design, and software development.
When considering the Lenovo ThinkPad Z13 and the Razer Blade 15 for general use, factors like panel type, resolution, and brightness play a key role, with both offering pleasant viewing experiences, but the Razer Blade offers slightly better visuals due to its higher resolution and brightness. For engineering and design work, accurate color representation is critical, and both laptops provide wide color gamuts, essential for tasks like photo editing or CAD work, although the Razer might edge out with better color accuracy. However, for gaming and 3D applications, a high refresh rate is crucial for smooth visuals, which neither the Lenovo ThinkPad Z13 nor the Razer Blade 15 prioritize, making them less ideal for fast-paced gameplay or intensive 3D modeling.

PCMag
Brian Westover | September 2022
"In the premium ultraportable space, the Lenovo ThinkPad Z13 competes with the best of the best, and still manages to shine. The design is an impressive departure from the bland bare-metal laptop that's become so popular in recent years, and the AMD-powered system has performance that's just as impressive. It's a stark alternative to the Intel-based majority, and it stands up well enough to the impressive Apple M2 processor."

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."
