Unleash unstoppable gaming power with the Alienware AC16251 – a laptop built for victory. Its razor‑sharp 16‑inch 240 Hz display and Intel Core Ultra 7 processor give you the edge you need to dominate every match.
Designed for gamers, the sleek indigo chassis combines an anodised aluminium lid with a thin profile (1.63 cm rear, 1.92 cm front). The WQXGA 2560 × 1600 screen delivers 500 nits brightness, 100 % DCI‑P3 color gamut and ComfortView Plus low‑blue‑light technology, while the 240 Hz refresh rate keeps motion buttery smooth.
Under the hood, a 20‑core Intel Core Ultra 7 (12 E‑cores, 8 P‑cores) reaches up to 5.2 GHz, paired with an NVIDIA GeForce RTX 5060 8 GB GDDR7 GPU and 32 GB DDR5‑5600 memory. A 1 TB PCIe 4.0 SSD provides lightning‑fast storage, and the integrated AI accelerator (13 TOPs NPU) boosts creative and gaming workloads.
Stay connected with Wi‑Fi 7, Bluetooth, 1 × Thunderbolt 4, HDMI 2.1, and a full‑size Ethernet port. The 96 Wh battery recharges in just 3 hours with 180 W fast charging, while the RGB‑backlit keyboard and dual 2.5 W speakers round out an immersive experience.
