The Razer Blade 18 2025 is the objective winner of this comparison, securing more individual specification victories than its competitor. Its most significant advantage over the Dell Alienware m18 R2 2024 is the inclusion of Thunderbolt ports, which represents a 100% improvement in connectivity capacity. While both devices share a high number of identical specifications, the superior port configuration gives the Razer model a clear edge in hardware versatility for users requiring extensive peripheral support.

Users who prioritize connectivity and modern interface standards should choose the Razer Blade 18 2025 for its expanded Thunderbolt capabilities. Conversely, the Dell Alienware m18 R2 2024 is the better option for budget-conscious buyers, as it offers an 8% advantage in MSRP.
