Recently, Sapphire released a new teaser of its Radeon RX 7900 NITRO graphics cards and confirmed that the “Vapor-X” vapor chamber will return to the company’s graphics cards. Of course, the Vapor-X vapor chamber should not be confused with the Vapor-X series graphics cards of this company. In general, Sapphire’s Toxic, NITRO, and Vapor-X series graphics cards are equipped with a vapor chamber.

In addition to the vapor chamber, Sapphire’s new teaser confirms that the company’s Radeon RX 7900 XT/XTX NITRO graphics cards are going to be equipped with three 8-pin power inputs, and this is clearly evident in the new teaser. Also, this is the first time we’ve seen a custom Navi 31 board with 20 VRM phases up close.
As Sapphire’s teaser shows, the company’s custom board is not that much wider than AMD’s reference board, and Sapphire has limited itself to adding VRM phases and strengthening them and adding more parts to the same reference board. Of course, we must not forget that the changes made by Sapphire definitely increase the overclocking potential of the Navi 31 silicon on these cards.
The new Sapphire teaser has been published while we are less than two weeks away from the official launch of Radeon RX 7900 XT/XTX graphics cards by AMD. As you know, AMD is going to launch its new graphics cards with two RX 7900 XT and RX 7900 XTX models. Previously, it was rumored that custom RX 7900 graphics cards are going to be released one to two weeks after the reference models, but the release of this teaser shows that this is not supposed to be the case; At least in the case of Sapphire NITRO series graphics cards.
