Radeon RX 7900 XT(X) before the test: Raff shows the reference designs from AMD
From now on, testers can show that they have a Radeon RX 7900 XT(X) in their test laboratory. Of course, PCGH doesn’t want to be missing: Raff unpacks the two fastest RDNA 3 graphics cards and talks about his first impressions.
It has a certain tradition that new hardware can be shown at least in an unboxing before the test. Of course, this does not have anywhere near the depth of a real test, especially since the hardware must not be installed, but one or the other reader is happy if he can be there live when a new graphics card is unpacked for the first time. And so Raff is allowed to unpack two new Radeons in the video today: the RX 7900 XT (Navi 31 XT) and the RTX 7900 XTX (Navi 31 XTX).
RX 7900 XT(X): cooler, connections, power consumption
The “cold” graphics cards are completely black (backplate, fins, fan hood, etc.), which at least makes Raff very happy. As expected, the reference designs are no longer dual-slot cards, so they need three slots and also some distance to the next slot card. In the video, Raff reveals that the previously known technical data of the RX 7900 XT has changed, but this is still subject to a non-disclosure agreement. The three fans of the XT are not very spectacular with a diameter of 80 millimeters. On the connection side, Radeon is the leader: According to Raff, the 7900 cards will outperform all others on the market, including Arc and RTX 40. The connections include HDMI 2.1a, Display Port 2.1, USB-C and another Display Port.
The fact that the slot panel is otherwise closed has a system: the air is discharged to the side via the slats, not via the panel. Raff also explains in the video that Ati Technologies still plays a role at AMD. The vapor chamber and the other cooling elements shouldn’t show. With a good 300 watts of power consumption, Raff assumes that the Radeon RX 7900 XT will not be particularly loud. As a result, two 8-pin power sockets are sufficient, which AMD also aggressively advertises. If your power supply already creates a Radeon RX 6800 XT, you don’t have to worry about the RX 7900 XT(X) either.
The big sister 7900 XTX is definitely a bit taller, which means a higher cooling surface. This is also required for the 355 watt TBP. The fan diameters are 85 millimeters. You can find more details such as dimensions of the reference cards, weight, PCI Express and the light strips in the video. For technical details on the Radeons presented, we refer to the technology deep dive RX 7900 XT(X). Photos of the cards can be found in the gallery.
