The ASUS ROG Flow X13 is more portable, offers better performance for 3D and machine learning tasks with its newer GPU, and makes for a versatile choice with its touchscreen and 2-in-1 form factor, suitable for general use and gaming alike. The Razer Blade 15, on the other hand, although slightly heavier and less portable, has a larger screen with higher refresh rates, which could be better for gaming and media consumption. It might be more appealing if you're looking for a laptop with a more traditional aesthetic and do not require the latest GPU for your tasks. Both laptops have similar storage and memory, and are suitable for engineering applications, but the decision may come down to whether you prioritize portability and cutting-edge GPU performance (ASUS) or a larger display and a more conventional design (Razer).

How the ASUS ROG Flow X13 and the Razer Blade 15 compare to other laptops
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."
"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."
