To choose between the Dell Inspiron 16 5620 and the Razer Blade 15, consider how you'll use the laptop. If high performance for gaming or intense graphic work is a priority, the Razer Blade 15 typically offers more power and better graphics capabilities, but it comes at a higher price. On the other hand, the Dell Inspiron 16 5620 could provide a balance of performance and value, suitable for everyday tasks and some light creative work. It's usually more affordable but may not handle demanding tasks as well. Battery life can be a deciding factor, too; check which model offers longer unplugged usage if you're often on the move. Portability is another consideration; gaming laptops like the Razer Blade 15 may be bulkier and heavier, while the Inspiron is likely to be lighter but still large due to its 16-inch screen.

The Razer Blade 15 is very good for gaming and AI, while the Dell Inspiron 16 5620 is only fair.
The Dell Inspiron 16 5620 offers modest gaming performance with its integrated Iris Xe graphics and 60Hz screen refresh rate, whereas the Razer Blade 15 excels in gaming thanks to its dedicated Nvidia RTX 3070 Ti graphics card and a much higher 240Hz refresh rate which provides smoother visuals. Additionally, the Razer's superior CPU adds to its gaming prowess, although both laptops have high-quality screens.

The Razer Blade 15 is very good for engineering and design, while the Dell Inspiron 16 5620 is good.
The Razer Blade 15 is considered very good for engineering and design use due to its more powerful Intel i7 processor, superior Nvidia RTX 3070 Ti GPU, and higher resolution screen, providing better performance and detail clarity which are crucial for demanding tasks. In contrast, the Dell Inspiron 16 5620, while still suitable for engineering and design, has a less powerful Intel i5 processor and integrated graphics, which may limit performance in intensive applications, but offers silent operation and a larger screen at 16 inches that some may prefer for productivity.

The Razer Blade 15 has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron 16 5620, with its fair screen quality for general use, likely offers a balance between resolution and brightness, suitable for everyday tasks but may lack the high resolution and exceptional brightness preferred for more vibrant displays. For engineering and design work, the screen's fair quality implies it covers enough of the professional color gamuts to be serviceable, but isn't top-tier in reproducing precise colors. However, its poor screen quality for gaming and 3D indicates a lower refresh rate, which can result in less fluid visual experiences that are less immersive or responsive than what's provided by screens designed specifically for those purposes.

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."

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."
