GUNNIR Intel Arc A770 Photon 16G OC W GDDR6 Graphics Card
The GUNNIR Intel Arc A770 Photon 16G OC W GDDR6 is a high-performance, visually stunning graphics card tailored for both gamers and creative professionals. Powered by Intel’s Arc A770 GPU architecture, this card features 16 GB of GDDR6 memory on a 256‑bit interface, delivering rapid data throughput to handle modern, demanding workloads with ease. Engineered for impressive visuals, it supports ultra‑high resolutions—up to 7680 × 4320 at 60 Hz—making it ideal for immersive 4K gaming and multi-display setups. It offers flexible connectivity with three DisplayPort 1.4a ports and one HDMI 2.0, enabling seamless multi-monitor configurations (up to four simultaneous displays). Performance and efficiency are enhanced by modern API support—DirectX 12 Ultimate and OpenGL 4.6—along with Xe Super Sampling (XeSS), Intel’s AI-driven upscaling technology, to boost frame rates without sacrificing visual fidelity. The card also integrates Intel Deep Link and Stream Assist, enabling intelligent task allocation and offloading streaming workloads for optimized multitasking and content creation workflows. In terms of design, the Photon OC variant sports a triple-fan cooling solution housed in a sleek, limited-edition shroud—offering both efficient thermal performance and an eye-catching aesthetic. It draws 285 W of power and requires two 8‑pin connectors, with systems recommended to have a 600 W (or higher) PSU for stable performance. Compact at approximately 300 × 118.5 × 50 mm, it fits most high-end builds comfortably.
