The Gigabyte A5, being less expensive, offers a balance of cost and functionality with its decent performance and battery life, suitable for general gaming and tasks. However, the HP Omen 15, while slightly pricier, has a stronger processor, a more powerful graphics card, and a longer battery life, making it a better choice for intensive 3D, machine learning tasks, and gaming. Note that HP Omen 15's superior power comes with added weight, affecting its portability. Both have a similar screen size, resolution, and type, but the HP Omen has slightly better overall performance and color accuracy, beneficial for engineering and design work. Give Feedback

The HP Omen 15 has a better screen than the Gigabyte A5 for content creation, and software development.
When considering a laptop for general use, the Gigabyte A5 and HP Omen 15 both have adequate resolutions and brightness, along with the suitable panel types that give clear images and vibrant colors. For engineering and design work, however, both laptops may lack wide color gamuts like DCI-P3 and Adobe RGB, which are crucial for accurate color work and detailed graphics rendering. Conversely, for gaming and 3D applications where fluid motion is key, the lower refresh rates on these laptops can mean less smooth visuals, a tradeoff against their fine detail at static images.

Florian Glaser | September 2022
"Ignoring price, the Gigabyte A5 has a hard time against the similarly fast competition. Besides the loud noise in 3D mode (performance mode), the high temperature development of the components should be mentioned on the downside. Despite the relatively thick case, the laptop gets very warm and loud under load, which does not exactly speak for the cooling system. The plastic surfaces look rather cheap and also tend to rattle. In most other disciplines - be it the input devices, the screen, the connectivity or the battery runtime - the Gigabyte laptop does not stand out from the crowd, neither positively nor negatively. However, those who primarily pay attention to the price-performance ratio will get a pretty good offer with the Gigabyte A5."

"We consider around 1,260 Euros (~$1530) for a Ryzen 7 4800H, a GeForce RTX 2060, a 512 GB SSD and 16 GB dual-channel RAM to be a good offer that appeals to price-conscious gamers. Very high details are rarely a problem in the native resolution of 1,920 x 1,080. Buyers will also be spoiled with a top-notch battery life that even beats most other notebook classes. If HP now improves the speed of the WLAN module, the stability of the case and the repeatedly criticized picture quality, the competition will have to dress extra warmly."
