Sapphire’s Vapor-X model is $100 more expensive than the reference card at $1,099. Unfortunately, the manufacturer’s suggested retail price means little. Newegg has a listing for $1,522.97 (opens in new tab) — plus $49.99 shipping, add insult to injury. (From a third-party vendor, of course.) Not that the reference 7900 XTX is better, but for now Listed for $1,439.99 from another third-party seller (opens in new tab).

Hopefully supply and pricing will improve in the coming months, but right now all 7900 XTX cards are pretty overpriced.The 7900 XTX typically outperforms the RTX 4080 in rasterization performance, a significant difference in complex ray tracing games, but the RTX 4080 card Starting at $1,269.99 (opens in new tab)That’s more than we’d like, but it’s about $200 cheaper than the 7900 XTX for the time being.
