The Intel Arc B580 is currently the most powerful model in Intel’s new generation graphics card lineup. The ASRock Steel Legend 12GB OC version offers more efficient cooling, very low noise levels, and striking ARGB lighting compared to the base models. Its performance beats the RTX 3060, but it falls behind newer rivals. Compared to cards like the RTX 5060 or RX 9060 XT, it stands out more for its larger memory than for its price-to-performance ratio.
The card is equipped with a 2.5-slot cooler featuring three fans that blow air down onto a heatsink with transverse finning. The cooler shroud combines white and gray plastic, complemented by gray printing. The fans are transparent and are illuminated by addressable RGB LEDs.
The backplate on the rear of the card is metal. There is an opening at the back through which some of the heated air can flow over the card. On the side of the card is a Steel Legend logo, which is illuminated by addressable RGB LEDs.
The heatsink with transverse finning occupies most of the space under the shroud. Almost the entire rear half of the card consists of an openly pass-through heatsink, which contributes to efficient cooling.
The fan impellers have a diameter of 8.8 cm and a height of around 12 mm, which can be considered a medium size.
Detail shows the cooling of the MOSFETs and coils on the power delivery stage. They are cooled directly by the large heatsink via thermal pads.
The length of the card from the bracket is approximately 29.5 cm. The cooler extends about 2 cm beyond the bracket in width. The card measures about 4.5 cm in height and occupies two and a half slots.
The weight of the card is only 968 grams, placing it among the lighter models.
Unlike the previous Arc generation, this card offers better support for modern standards, including HDMI 2.1a and DisplayPort 2.1. However, it still lags somewhat behind the latest GeForce and Radeon cards in terms of bandwidth. Only the middle DisplayPort connector supports UHBR13.5; the remaining two are limited to UHBR10.
On the edge of the PCB is a switch to turn off the lighting and an ARGB connector, to which you can connect additional ARGB LED elements and synchronize them with the card’s lighting using the manufacturer’s software.
For auxiliary power, a pair of classic 8-pin connectors is used. They are oriented with the latch facing downward.
That covers the card’s construction; let’s move on to the test build and results.
