LG Gram SuperSlim vs Razer Blade Stealth 13
The Verdict
LG's Gram SuperSlim dominates on portability and battery life, weighing just 2.18 lbs with up to 12 hours of runtime compared to Razer's 3.09 lbs and 7-hour capacity. The larger 15.6-inch OLED display offers superior contrast and color accuracy at 1920x1080, making it better for creative work despite matching the Razer's 400 nits brightness. Performance differs meaningfully: LG uses the newer Intel Core Ultra 7 155H with 16 cores (6P+8E+2LPE) versus Razer's older 12th-gen Core i7-1260P with 12 cores (4P+8E). Both carry identical 16GB RAM and 512GB SSD storage, though LG uses faster LPDDR5X memory. Razer compensates with a slightly more premium aluminum chassis and traditional HDMI output, plus a 13.3-inch IPS screen with 1200p resolution for sharper text. At $100 less, the LG offers exceptional value for travel-focused users who prioritize battery endurance and screen real estate. Razer suits those needing legacy HDMI connectivity and a more compact footprint, though its older processor and mediocre battery life limit appeal at this price point.
