Arc B580 12 GB for white-themed builds

The ONIX LUMI Arc B580 12GB graphics card targets enthusiasts building white-themed systems. Its Intel Arc B580 GPU delivers 20 Xe-cores clocked at 2740 MHz alongside 12GB of GDDR6 memory on a 192-Bit interface. The PCI Express 4.0 x8 connection suits modern platforms and the card supports DirectX 12 Ultimate plus OpenGL 4.6 for current APIs.

ARGB lighting and aluminium backplate

A programmable ARGB logo on the shroud offers 16.8 million colours with software control for effects, brightness and synchronisation. The aluminium backplate adds structural rigidity and a clean white finish that matches the shroud. Dual ball-bearing fans keep acoustic output below 30 dBA while maintaining component temperatures.

Four modern display outputs

One HDMI 2.1 port and three DisplayPort 2.1 connectors drive up to four monitors simultaneously. The white colour scheme extends across the shroud and backplate for visual consistency in light-coloured cases. Standard mounting brackets fit typical ATX chassis without special clearances.

Questions about this item

Will the dual ball-bearing fans need replacement after long-term use?

The dual ball-bearing fans are designed for reliable, long-lasting cooling and a noise level kept below 30 dBA, reducing wear compared to sleeve-bearing alternatives.

What limits performance first during sustained workloads?

The PCI Express 4.0 x8 interface provides half the lane bandwidth of a full x16 link, which can become the bottleneck before the 12GB GDDR6 memory or 20 Xe-cores saturate.

How much heat and noise does the card produce when running all day?

Noise stays below 30 dBA thanks to the dual ball-bearing fan design, while the aluminum backplate helps dissipate heat from the 2740 MHz core clock and 19000 MHz memory.
