Lenovo Yoga Slim 7i Gen 9 vs Samsung Galaxy Book4 Pro
The Verdict
Both laptops share the same Intel Core Ultra 7 155H processor and 16GB RAM, delivering comparable performance for productivity and light creative work. The Lenovo Yoga Slim 7i Gen 9 offers better value at $1199 with a 1TB SSD versus Samsung's 512GB configuration, plus its 14.5-inch OLED touchscreen at 2880x1800 resolution provides vibrant colors and pixel density. Samsung's Galaxy Book4 Pro counters with a larger 16-inch Dynamic AMOLED 2X display (500 nits versus 400), superior brightness for outdoor use, an extra USB-A port, and SD card support. The Samsung weighs 50 grams less (1.55kg) and measures thinner at 12.5mm. Battery performance favors Samsung with 15 hours versus Lenovo's 14 hours. For most users, the Lenovo delivers excellent value with double the storage and a highly responsive touchscreen in a slightly smaller, more portable package. Choose Samsung if you need the larger screen, brighter display, and maximum portability, or if SD card expansion matters for your workflow. Lenovo wins for value-conscious buyers prioritizing storage capacity.
