What CPU should I pair with a Arc 5 B580?
At 1080p the best match from our database is the Core i3-8350K, which leaves only 2.6% of the combined potential unused and lands around 57 fps in a typical AAA title. The table above lists five more, ranked by how little each pairing wastes rather than by raw speed.
Bear in mind that the right processor depends on the resolution you play at. At 1440p and 4K the card does proportionally more of the work, so a cheaper chip than the one listed will keep up — the pairing only gets tighter as resolution falls. At 4K this card is 98% utilised, so almost any modern processor is sufficient.
Who a Arc 5 B580 is actually for
This is mainstream 1080p hardware. At that resolution it is usually the component doing the limiting, which is good news for pairing — it will not be held back by a modest processor, so there is no need to spend heavily on the chip beside it.
Pushing it to 1440p is possible in lighter titles, but expect to drop settings in demanding ones.
Is 12 GB enough?
At 1440p and high settings, 12 GB clears every title we model with room to spare. Memory is not the constraint on this card, and it is unlikely to become one within its useful life.
Is 12 GB of VRAM enough for the Arc 5 B580?
Yes. At 1440p on the high preset, 12 GB covers every title we model with room to spare, so memory is not the constraint on this card.
What bottlenecks a Arc 5 B580?
At 1080p this card is normally the limiting component itself. At 4K it is 98% utilised, meaning nearly all the work sits on the card and the processor barely matters.
