Gunnir Photon OC Arc B580 Review

Gunnir Photon OC Arc B580 is a entry-level Intel graphics card built on the Xe2-HPG Battlemage (BMG-G21) architecture, with 12GB of GDDR6 memory, a 2670MHz boost clock, and a 190W TDP. It is Intel's second-generation discrete card, offering 12GB of VRAM at an unusually low price for the tier.

If you're shopping for a entry-level card, the Gunnir Photon OC Arc B580 lines up against AMD's Radeon RX 7600 in this catalog. Expect a card around 305mm long needing a 2.5-slot opening in your case, with xe2-cores count of 20 feeding its rendering pipeline. Launch MSRP was $249, though street pricing has moved since.

Performance and Architecture

Built on Intel's Xe2-HPG Battlemage (BMG-G21) architecture, the Gunnir Photon OC Arc B580 pairs 20 xe2-cores with 12GB of GDDR6 memory on what Intel rates as a 2670MHz boost clock. That combination places it in the entry-level tier, where it's tuned for a specific resolution and refresh-rate target rather than being a universal do-everything card.

Power, Size, and Compatibility

At a 190W TDP, the Gunnir Photon OC Arc B580 needs a power supply with enough headroom on the 12V rail plus whatever PCIe power connectors this variant uses. Physically it runs about 305mm long and occupies a 2.5-slot opening, so measure your case's GPU clearance and front intake fans before buying, especially in compact builds.

Comparison to Alternatives

The closest rival to the Gunnir Photon OC Arc B580 in this catalog is AMD's Radeon RX 7600, which competes at a similar price and resolution target. Shoppers who need more VRAM headroom or lower power draw than the Gunnir Photon OC Arc B580 offers should cross-shop that card before deciding, since the two trade blows depending on the game engine and whether ray tracing or upscaling is in use.
