The Lenovo Slim 7 16 is much less expensive, offering good performance for general use and less intensive engineering tasks with decent battery life and portability. In contrast, the Razer Blade 18 is considerably more expensive, with superior performance for 3D rendering, machine learning, and gaming, although it is heavier and has a shorter battery life. If cost is a concern and you require a lighter laptop for everyday tasks and some light creative work, the Lenovo is a solid choice. However, if you are focused on high-end gaming or demanding engineering tasks and can invest more, the Razer Blade 18 is better equipped to handle those needs. Give Feedback

"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."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
