With the RX 7900 XT and XTX already in the market, AMD has a big gap in its mainstream Radeon lineup. The company could be ready to fill it with the new Radeon RX 7800 and 7700 graphics cards, based on Navi 32 silicon.

According to YouTube channel Moore’s Law Is Dead, the new cards are set to launch this September. They will come in two variants, a full-size Navi 32 chip with 60 Compute Units and a cut-down version with either 48 or 54 CUs and 16GB of VRAM. The full-size chip is likely to be called the RX 7800 XT, while the cut-down chip will probably get the RX 7700 XT name.

The performance-mainstream cards are expected to perform better than the current RX 6800 and 6700 XT, delivering a gen-over-gen upgrade of around 16%. Renowned hardware leaker All The Watts!! posted a 3DMark Time Spy benchmark score of 18,957 points, which is very close to Nvidia’s GeForce RTX 4060Ti (18,800).

While the prices and performance numbers have yet to be confirmed by AMD itself, the rumours seem fairly legitimate. The upcoming cards are said to be based on the same GPU architecture as the RX 7900 XT and 7900 XTX, but with lower clock speeds.

Aside from that, the 7700 and 7800 will be using a more power efficient memory configuration. They will also be using smaller GDDR6 memory chips, which should allow them to fit within the $269 and $549 price brackets of the current RX 7000 series lineup respectively.

What isn’t clear, though, is whether the non-XT versions of the cards will be released before the XT models. The RX 7900 XT is supposed to be harvesting the unused dies from the 7900 XTX and XTXX, so it’s not too hard to imagine that a vanilla version of the card would use some of those chips as well.

Considering the current state of the GPU industry, it’s quite likely that AMD will release the new RX 7800 and 7700 before the end of the year. It will be a nice boost for consumers who want to enjoy high-resolution gaming on their PCs without having to spend a fortune on the latest GPUs. Of course, if you can’t wait for the new cards to arrive and don’t feel like dropping over $700 on a graphics card, there are plenty of RX 6700 and 6800 XT alternatives out there that offer comparable performance for a much lower price.
