Online users have published what might be the first clear images of an AMD Radeon RX 7000 series graphics card. A few pictures were released by the typically trustworthy Twitter-based leaker HXL with credit to “QQ,” a Chinese social networking site and instant messaging app owned by Tencent.

It’s thrilling to get what could be the first accurate look at one of AMD’s next high-end RDNA3 chiplet-based desktop graphics cards, but please take what is at most an engineering sample design with a grain of salt.

Whatever the name of the 7900 cards is, the fans seem a little bigger. Using the 6900 XT as a scale, 82–83mm is suggested for the fan size. Comparatively speaking to non-reference cards that we’ve reviewed, that’s still not exceptionally enormous. As an example, the Asus RTX 4090 ROG Strix has 104mm fans, while the RTX 3090 Ti TUF Gaming from the previous generation has 97mm fans. Larger fans could be necessary, though, as both cards have 450W TBP ratings.

A top-down image comparison shows the alleged new AMD Radeon RX 7000 graphics card to be the lower of the two, and if the images are real, there are some further intriguing tidbits to savour.

First off, two 8-pin power connectors are still used to power the new card (the one with the red stripe). If nothing needs to change, don’t. This suggests that the speculations of a 350W TDP may not be too far off.

The maximum draw for such a system ought to be 75W through the PCIe socket and 150W per 8-pin connector (375W). This figure should be safely undershot by the manufacturer. Additionally, the alleged power efficiency of RDNA 3 eliminates the requirement for a plethora of 8-pin ports or the problematic 16-pin architecture that Nvidia and its partners used with the GeForce RTX 4090.

From the top-down view, we can also observe that the AMD RX 7900 XT/XTX has a development PCB. There are several protruding pins that developers can use for things like direct monitoring, diagnostics, and programming of the hardware because the PCB isn’t covered by a backplate like a premium consumer design.
