Additionally, the Gigabyte has a larger screen and a higher refresh rate for better visual experience, but it is heavier and will be less convenient to transport. The Dell has longer battery life, so if you're often on the go and away from power outlets, it might serve you better in that aspect. Give Feedback

The Dell Inspiron 15 3511 has a better screen than the Gigabyte A7 for software development, and content creation, while the Gigabyte A7 has a better screen for general use, gaming and AI, and engineering and design.
The Dell Inspiron 15 3511, with its fair screen attributes, will suffice for everyday tasks like browsing and document editing, but its limited color range and brightness can diminish the experience for detailed engineering and design work, and its lower resolution and sluggish refresh rate could hinder the immersion and responsiveness necessary for gaming and 3D applications. Conversely, the Gigabyte A7's good screen quality enhances general usage with better resolution and brightness, offering a more vibrant and sharper display, while the wider color gamut benefits professionals in engineering and design who require accurate color reproduction for their work. However, the A7's lower refresh rate, despite its good resolution and panel type, fails to deliver the ultra-smooth visuals passionate gamers and 3D artists seek for an optimal experience.

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"In terms of looks, the Gigabyte A7 X1 is certainly not a trendy, slim, and ultra-mobile gaming laptop. But it does what it's supposed to do, namely bringing games smoothly onto the screen, very well. Both the processor and the GeForce RTX 3070 are able to unleash their performance without restrictions thanks to the well-ventilated case. The Gigabyte A7 X1 brings modern games smoothly onto the screen and offers excellent maintenance options."
