ASRock Challenger Arc B580 CL 12GO graphics card

12GB GDDR6 capacity

The ASRock Challenger Arc B580 CL 12GO is a graphics card built around the Intel Arc B580 GPU with 12GB of GDDR6 memory on a 192-bit interface. It targets gamers and creators who need solid 1440p performance and multi-monitor flexibility. The dual-fan cooler fits a standard ATX form factor.

PCI Express 4.0 x8 interface

The card connects via a PCI Express 4.0 x8 slot and draws power through a single 8-pin connector with a 650W PSU recommendation. It replaces older GPUs limited to PCIe 3.0 or lower memory bandwidth. The jump is worth it when your current card cannot drive 7680 x 4320 resolution or lacks DisplayPort 2.1 with DSC support.

20 Xe-cores at 2740 MHz

Twenty Xe-cores running at a 2740 MHz core clock handle modern titles at high settings and accelerate content-creation workloads. The 12GB frame buffer provides headroom for large textures and multi-tasking across up to four displays. Limits appear in sustained 4K gaming or heavy compute tasks that exceed the 192-bit memory bus throughput.
