How the Arc B580 performs at 1080p, 1440p and 4K
At 1080p the Arc B580 averages about 99 fps on High across the 14 games people check most. Most games hold 60 fps with room to spare.
At 1440p the typical result drops to 72 fps. 1440p on High holds 60 fps in most games. At 4K it is about 43 fps. 4K is possible in lighter games, but use upscaling in anything demanding.
The heaviest game we checked is Black Myth: Wukong, at 57 fps on High at 1080p. The lightest is Fortnite, which the card handles at 300+ fps. If your own games are somewhere in between, the table above shows where.
Memory and power
12 GB of video memory is comfortable for 1440p and gives you room for the next few years of releases.
The Arc B580 is rated at 190 W. With a mid-range processor, plan on a 550 W power supply (450 W is the minimum). That is a moderate load. Any case with a front intake fan will keep it cool.
Where it sits
Released in 2024, the Arc B580 is still a current card. The next card up in our list is the Radeon RX 6750 XT, about 6% faster (launch price $549). The next card down is the Radeon RX 7600 XT, about 6% slower.
It launched at $249, which works out to 13.3 points of performance per $100. Prices on the used and discount market are different, so treat this as a way to compare cards, not as today's price.
Which processor to pair it with, and who it suits
To keep a processor from holding it back at 1080p, you want something like a Core i3-10300, and at 1440p a Ryzen 3 3200G or similar. Slower processors will still work, but you give up some of the card's speed. The best CPU list for this card shows the options for all three resolutions.
The Arc B580 is a good fit for 1440p at High and for 1080p at Ultra on a fast monitor. It is the tier most people should look at first.
