Lenovo IdeaPad Slim 3 15IWC11
Lenovo's IdeaPad Slim 3 15IWC11, also listed as the IdeaPad Slim 3 15 Gen 11, pairs the six-core Intel Core 7 350 (Wildcat Lake) with a 15.3-inch 1920x1200 120Hz touchscreen, 16GB of DDR5-5600 and a 50Wh battery in a 1.59kg plastic chassis. This is the 83RR configuration with a 512GB SSD; other versions start at Core 3 304 or add a 2.5K OLED panel up to 165Hz.
Pros
- 120Hz 15.3-inch 1920x1200 touchscreen with 100% sRGB coverage, measured above 400 nits in review testing
- Uses less power than the previous-generation Core 5 210H model despite similar performance in review testing
- Upgradeable memory and storage: a DDR5 SODIMM slot (up to 32GB) and an M.2 2242 PCIe 4.0 SSD slot (up to 1TB)
- Lenovo rates the 50Wh battery at 18.5 hours of 1080p local video playback, with Rapid Charge Boost for about 2 hours of use from a 15-minute charge
Cons
- Only one SODIMM slot, so memory runs single-channel
- The only USB-C port is limited to 5Gbps, and video output is HDMI 1.4 and DisplayPort 1.2 only
- Plastic chassis carried over from the 2025 model, with a 720p webcam and no keyboard backlight on this configuration
- Overall performance in review testing was roughly on par with a three-year-old Core i7-1355U, so it is no big step up for U-series laptops
