Since you're considering the ASUS ROG Zephyrus G15 and the Lenovo Slim 7 16, and price is a key factor, think about your primary use for the laptop. The ASUS is typically more expensive due to its gaming-oriented features, such as a high-performance graphics card and faster screen refresh rates, which are great for gaming and resource-intensive tasks. It may also have a more robust cooling system to manage the heat from these components. The Lenovo, however, is designed to be slim and portable, which means it's easier to carry around but might not have the same level of performance for demanding software or games. The trade-off with portability is often battery life and performance; lightweight laptops may not last as long on a single charge and might not handle intense workloads as well as gaming laptops. If you need a laptop for general use, with occasional light gaming or creative work, and value portability and battery life, the Lenovo could be more suitable and budget-friendly. However, if you are an avid gamer, or if you work in fields that require strong graphics capabilities, like 3D animation, machine learning, or engineering simulations, the ASUS could justify the additional cost with its superior performance.

The ASUS ROG Zephyrus G15 is good for gaming and AI, while the Lenovo Slim 7 16 is only fair.
The ASUS ROG Zephyrus G15 outperforms the Lenovo Slim 7 16 for gaming and 3D tasks primarily because it has a superior GPU in the form of the Nvidia RTX 3070, compared to the RTX 3050 in the Lenovo, resulting in significantly better handling of graphics-intensive tasks. Both have high screen refresh rates which are crucial for smooth visuals in gaming and 3D applications, but the better GPU in the ASUS makes it more suitable for these purposes.

How the ASUS ROG Zephyrus G15 and the Lenovo Slim 7 16 compare to other laptops
"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."
"At $1,011, the Lenovo IdeaPad Slim 7 Pro is a real bargain among full-sized laptops, with a handsome 16-inch, 16:10 aspect ratio touch screen, a speedy CPU, a comfortable keyboard, ample memory, and a roomy solid-state drive. It's not a blazing gaming rig or mobile workstation, but it doesn't pretend to be. Its biggest negative is that it may be hard to find—during our review, it sold out and was marked "Temporarily Unavailable" on Lenovo's site."
