Dell XPS 15 (2024) vs LG Gram SuperSlim
The Verdict
Both laptops share the same Intel Core Ultra 7 155H processor and 15.6-inch OLED displays, but diverge significantly in practical design and performance. Dell's XPS 15 delivers superior specifications: 32GB RAM versus 16GB, a sharper 3456x2160 resolution versus 1920x1080, and an additional USB-A port plus microSD card reader for connectivity flexibility. Battery life edges toward the XPS at 13 hours mixed use. LG Gram SuperSlim excels in portability at just 0.99kg (versus 1.86kg) with an ultraslim 10.9mm chassis, making it genuinely mobile for frequent travelers. Storage remains non-expandable on LG but both offer 512GB SSDs. At $1499 versus $1699, Dell provides substantially better value with doubled RAM, higher resolution, and more ports. Choose the XPS 15 for power users prioritizing performance and versatility; select LG only if ultraportable form factor outweighs the specification and price disadvantages.
