The Lenovo Legion Slim 7 is often somewhat less expensive and boasts a slightly bigger 16-inch display with a higher 16:10 aspect ratio conducive to productivity tasks, a fast refresh rate, and a higher battery capacity for longer usage times, making it well-suited for both gaming and engineering use. It features the latest Nvidia RTX 4060 graphics and has a good portability score, although it’s slightly larger and heavier. The Razer Blade 15, on the other hand, offers a premium build quality with a more compact and lighter form factor, and although it has a lower battery capacity, leading to less time between charges, it also includes powerful Intel i7 processing and the Nvidia RTX 3070 Ti graphics, making it a strong contender for gaming, 3D rendering, and engineering tasks. Choose the Legion if you prefer a larger screen and longer battery life at a lower cost, or the Blade if portability and build quality are your priorities, albeit at a higher price. Give Feedback

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."

"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."
