Verdict
With the Radeon RX 7800 XT running 68% above the Arc B570 — a $540.00 premium — the two cards sit in meaningfully different price brackets. The Arc B570 wins on value unless the extra performance matters for your workload.
The Radeon RX 7800 XT's 16 GB of VRAM is a 6 GB advantage over the Arc B570. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
Budget-conscious buyers have an extra option: the Radeon RX 7800 XT can be found used on eBay around $449.99, roughly $350.00 below its new street price. If you're comfortable buying used, that saving could shift the value equation between these two cards.
Unless you specifically need what the Radeon RX 7800 XT offers, the Arc B570 is the stronger value at this price gap.
