Why we like it
It was the least expensive 7900 XT here at the time of writing. Like the Sapphire Pulse 7900 XT, it has a 2450MHz boost clock, while the PowerColor 7900 XT uses a 2400MHz boost clock. No dimensions are published for the ASRock 7900 XT Phantom Gaming; get length and thickness from the maker's page first.
When we checked, only the ASRock 7900 XT Phantom Gaming White cost less, and the Sapphire 7900 XT cost more. If you want a confirmed cooler thickness, look to the Sapphire Pulse 7900 XT instead: it comes in at 2.7-slot, while this one gives no figure.
