Verdict
The Arc B580 and RTX 5050 land at nearly identical prices — within 3% of each other — so your decision should come down to features, ecosystem fit, and availability rather than budget.
The Arc B580's 12 GB of VRAM is a 4 GB advantage over the RTX 5050. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
If we had to pick one: the Arc B580 edges it on raw VRAM, which carries more weight the longer you hold onto a card.
