A prototype AMD graphics card has been spotted – believed to be a Navi 31 model, possibly the RX 7900 (we’ll come back to this point) – and it shows that the GPU will work with a pair of 8-pin power sockets.
The image was shared on Twitter by hardware hacker HXL, who regularly contributes to GPU leaks, and is believed to have come from a QQ chat group (in China). So heavy seasoning is required here, but that said, the photo appears to be genuine (if it’s fake, it’s a good effort with some attention to detail).
The graphics card is obviously an engineering sample (pre-release) as it has a red panel design (the final product won’t), as well as voltage contacts (for engineers to use for debugging and so on) like the VideoCardz (opens in new tab)who spotted the tweet, points out.
As you can see, it’s a triple-fan card, slightly larger than its Navi 21 predecessor, and with red stripes on the heatsink, as seen in AMD’s teasers for its next-gen GPUs lately.
Breakdown: This is good to see, but triple 8-pin could still happen
We already knew that AMD wasn’t going the same way as Nvidia’s RTX 4090 in terms of using the 16-pin power connector (and therefore a 12VHPWR power adapter for use with traditional ATX 2.0 power supplies) with its RDNA 3 flagship, as the company has done confirmed this recently.
The reason this announcement was greeted with a sigh of relief was two-fold: because of the melting cable incidents we’ve seen with the 4090, and also because it shows that the power needs won’t be as large as Nvidia’s (in case you’ve been to any doubt about it).
So it’s great to see a Navi 31 graphics card with a single pair of 8-pin connectors required for power. Especially recently, we’ve been chewing on speculations as to whether this might be the case or if we could see 3 x 8-pin sockets for the RDNA 3 flagship. That said, there’s another rumor that there might be a supercharged version of AMD’s next-gen flagship , an XTX variant, which confuses things slightly – and could have a trio of power sockets, as reported.
To break it down a bit, 2 x 8-pin slots equates to a 350W graphics card probably, or thereabouts (each slot provides 150W, making 300W, plus 75W fed through the PCIe slot for a max of 375W ). Based on the rumor mill, the 7900 XT – rumored to be one of the first graphics cards to arrive in years for AMD’s RDNA 3 series – is going to be a 350W card, hence the reasonable conclusion that this is what we have. you look here
If there is a more powerful RX 7900 XTX spin, it could require much more power (400W to 450W perhaps) and therefore would need the 3 x 8 pin connectors to provide enough juice for us to see such a board together with the vanilla 7900 XT.
In all honesty, though, we’re not convinced by this XTX guess, and it seems more likely that such a GPU, be it a 7900 XTX or 7950 XT, will go further down the triple 8-pin power setup. . However, this is all clearly speculation at this point.
What we do know is that we’re going to find out what AMD has up its sleeve for the initial release of RDNA 3 at a big event later this week (November 3rd). But these images showing a 2 x 8-pin Navi 31 board – assuming there’s no tampering – are a good sign in terms of using that power setup instead of a trio of 8-pin sockets. (Although as we just discussed above, this configuration could still appear on a more powerful Navi 31 model).
