Product identity

The ASRock Challenger Arc B580 graphics card delivers 12GB of GDDR6 memory on a 192-bit bus with a 2740 MHz core clock. It connects through a PCI Express 4.0 x8 slot and drives up to four displays via one HDMI 2.1 and three DisplayPort 2.1 outputs.

Who should choose it

Gamers and creators targeting 1440p resolution with DirectX 12 Ultimate support will find the 20 Xe-cores and 12GB frame buffer well matched. Builders limited to a 650W power supply or a case shorter than 249 mm should consider a smaller model.

Deciding specification

The 12GB GDDR6 memory capacity is the single figure that determines whether this card fits your workload. If your textures, assets or compute buffers regularly exceed 10GB, this 12GB model removes the bottleneck; if they stay below, a lower-capacity alternative may suffice.

Questions about this item

Does the Arc B580 need an 8-pin power connector and a 650 W PSU to run?

Yes, the card draws power through a single 8-pin connector and the manufacturer recommends a 650 W supply.

Will the PCI Express 4.0 x8 interface work on a motherboard that only has PCI Express 3.0 slots?

The card is backward compatible and will operate at PCI Express 3.0 x8 speeds when installed in a 3.0 slot.

How can I confirm the GPU is running at its 2740 MHz core clock after driver installation?

Open the Intel Arc Control overlay or a monitoring tool such as GPU-Z and verify the reported core clock matches 2740 MHz under load.
