Sparkle launches white-themed Arc B580 ROC Luna OC Ultra graphics card with 2800 MHz boost clock

Sparkle has officially released its latest high-performance graphics card, the Arc B580 ROC Luna OC Ultra. This new model sits at the top of Sparkle’s Arc B580 lineup, offering gamers and content creators a premium custom design with improved thermal and clock performance.

What sets the ROC Luna OC Ultra apart is its fully white aesthetic. Sparkle has extended the white colour scheme beyond just the cooler shroud and fan blades – even the PCB solder mask underneath is painted white. This all-white finish gives it a clean and distinctive look, likely to attract builders focused on themed PC setups.

The Sparkle Arc B580 ROC Luna OC Ultra graphics card features a 2.5-slot thick design and is visibly taller than standard full-height cards, extending by at least an inch. For cooling, Sparkle has equipped the GPU with an aluminium fin-stack heatsink, cooled by two 90 mm fans. This setup aims to ensure better thermal performance while maintaining quiet operation.

Under the hood, Sparkle has pushed the B580 silicon further than its other models. The ROC Luna OC Ultra boasts the company’s highest factory overclock for the Arc B580 series, with a max boost frequency of 2800 MHz. For comparison, Intel’s reference boost clock is 2670 MHz, while Sparkle’s previously released Titan OC variant reaches 2740 MHz.

The card also comes with increased power limits. While the reference Arc B580 has a 190 W power limit, the Luna OC Ultra pushes it up to 210 W, giving it more headroom for sustained high performance. It draws power through two 8-pin PCIe connectors, indicating the need for a decent power supply to support this high-end custom card.

Sparkle Arc B580 ROC Luna OC Ultra pricing

Although Sparkle hasn’t revealed an official price yet, it is expected to be positioned in the $250–$300 range, making it a strong contender in the upper mid-range graphics segment.

For those looking for a visually striking card that combines higher boost clocks and added thermal headroom, the Sparkle Arc B580 ROC Luna OC Ultra is shaping up to be a solid pick.
