W (~3 h 33 min of use)– heavy browsing in Chrome, Better Performance Mode, screen at 50%, Wi-Fi ON; So this is the point where some will ultimately need to decide what they want in their machine, since there are some differences here. The Intel model is the better gamer in the Quiet mode, while the Ryzen laptop is actually quieter in Quiet mode, but less powerful. The panel has a 165Hz refresh rate, which is plenty fast enough for every game I used. It also supports Gsync. For fast-paced games, you’ll also want to enable Overdrive in the Vantage software, which enables a 3ms response time.
On the Quiet profile, btw, the CPU runs at only 25W, with sub 30 dB noise levels and temperatures in the 50s C. In fact, all of the 5900HX CPU power profiles are lower wattage in comparison to the i9-11980HK. But the Ryzen CPU is clearly more efficient, as the actual performance is somewhat similar at those higher powers, and better at low power. Our Cinebench R15 loop test stands as proof, and here’s how the Legion 7 scores on the 4 different power profiles. By making a .bat file with the following text, I was able to load a static per-key RGB setting that I desired and then run that batch file to kill the process. This, in result, prevents the severe battery drain that the iCUE service causes, but still allows me to have custom colors that are not the default ones baked into the firmware. Here’s the .bat contents: R9 6900HX, GeForce RTX 3080 Ti Laptop GPU, 2x Samsung SSD 980 Pro 2TB MZ-V8P2T0 (RAID 0), IPS-Level, 3840x2400, 16.00 USB-C 3.2 gen 2 with DP 1.4(left and rear, with reas supporting PD), 1x USB-C 3.2(right), 3x USB-A 3.2, ethernet, HDMI 2.1On top of that, battery life isn’t much with this Intel HX configuration, which shouldn’t come as a surprise for anyone. Thus, if you need a laptop that will be used unplugged from the wall more often than not, once more, this might not be for you. The GPU performance is fairly similar between the two, with differences within the margin or error. The Intel model does have a slight edge in the CPU tests, though, both in multi-core and especially in single-core loads. Update: Our detailed review of the 2021 Lenovo Legion 7 is available over here, while our review of the Intel-based Legion 7 is also available over here. We’ve also put up a detailed comparison of the Legion 7 against two other popular 3080 Laptops out there, the Asus ROG Scar 17 and Zephyrus S17. My opinion? It probably won’t matter to most as I believe almost everyone is going to game in Performance or Balanced modes. And considering there’s a mere 2dB difference in Balanced vs Quiet on the Intel model, I see little point in even switching to Quiet mode on that one.
It turns out that the Legion 7 lives up to expectations for the most part. The couple of minor complaints I had with the Legion 5 Pro are certainly resolved with this model. But there are a couple more quirks that come up, which I wasn’t expecting. Rise of the Tomb Raider, set to its most demanding settings with ray tracing enabled, scored 99fps at native resolution, while the lowest score I got from Wolfenstein: Youngblood was 105fps and that was with ray tracing on, DLSS off and running maximum detail levels at 2,560 x 1,660. Drop the resolution down to FHD and the frame rate jumps to 141fps. W (~6-7 h of use) – 60Hz, 4K Netflix with Dolby Vision, fullscreen in Edge, Quiet Mode, screen at 60%, Wi-Fi ON;GPU performance was pretty consistent between models, which is to be expected since the power limits are the same. The only thing missing really is maybe a wider color gamut. After seeing so many 100% DCI-P3 screens, I find that I really prefer them. This panel is only 100% sRGB though. Still, that’s not necessarily a bad thing unless you need to do some serious color-sensitive work.
The speakers and webcam are both identical to the Legion 7i, so please refer to that article for my opinions on both. Battery life Spec-wise, the 2022 Legion 7i is built on the latest and most powerful Intel and Nvidia hardware available to date. The Core i9-12900HX is the top-performance mobile processor in Intel’s Alder Lake 12th-gen platform, with 16 Cores and 24 Threads. It is a hybrid design with 8 High-Performance and dual-threaded Cores, and 8 extra Efficiency cores, which work together in the various loads. The design and thermal module of this Legion allow the processor to run at up to ~115W of sustained power in demanding CPU loads.Battery:These systems do not support batteries that are not genuine Lenovo-made or authorized. Systems will continue to boot, but may not charge unauthorized batteries. Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and provides no warranties for failures or damage arising out of their use. Battery life (and recharge times) will vary based on many factors, including system settings and usage. Update: The 2022 updates of the Legion 7 series are available now, in both Intel+ Nvidia and AMD-exclusive options. Our detailed review of the 2022 Lenovo Legion 7i is available here.
