Just two days before the launch of the GeForce RTX 4080, AMD has decided to somewhat reduce the interest in NVIDIA’s new product by sharing details about its series of video cards Radeon RX 7900. These adapters are based on Navi 31 GPUs with RDNA 3 architecture.

AMD cards are physically more compact and do not require potentially problematic adapters to connect additional power. The company has already confirmed that the Radeon RX 7900 series models will compete with the GeForce RTX 4080, leaving no doubt that the GeForce RTX 4090 will remain the fastest gaming card for the time being.

Radeon RX 7900 PCB

Video cards of the Radeon RX 7900 series will have more phases of GPU power stabilization (20 phases in the XTX version), support for DisplayPort 2.1 and USB Type-C connectors. Not to mention standard dual 8-pin PCI-E connectors instead of 12VHPWR.

AMD also points out that both Radeon RX 7900 cards are shorter and thinner than the NVIDIA RTX 4080 (Founders Edition). The only thing they have in common is the PCI Express 4.0 interface.

Radeon RX 7900 display ports

Radeon RX 7900 XT/XTX also have the advantage of being equipped with ports for image output. DisplayPort 2.1 support with a bandwidth of up to 54 Gb/s is implemented for graphics cards on the Navi 31, while NVIDIA’s top video cards are limited to DisplayPort 1.4a with a peak of 32.4 Gb/c.

In the $900-1200 price range, AMD will offer more memory and more advanced display options. However, when it comes to performance, neither of the two companies is ready to compare the new products to their rival’s devices just yet. Since GeForce RTX 4080 is not yet released, AMD compares its new models with the flagship of the previous generation – Radeon RX 6950 XT. The company shares two charts, one showing rasterization performance and the other showing ray tracing.

Radeon RX 7900 performance

According to the data provided by the developers, the Radeon RX 7900 XTX in the case of classic rendering in 4K mode is 48-67% more productive than the Radeon RX 6950 XT, while the Radeon RX 7900 XT is 25-40% faster than the latter. At the same time, the younger model based on the Navi 31 is slower than the flagship by 18-21%. Considering the difference in the recommended price – $999 vs. $899, it’s the older version that will have the better performance-for-money ratio.

When using ray tracing, the difference between Radeon RX 7900 XTX and RX 7900 XT is much more modest – about 10%. However, we have to wait for independent test results. In the given graphs, when FSR is activated in some projects, the indicators increase by 2-3 times, which requires confirmation.

The launch of the AMD Radeon RX 7900 series is still a month away. There’s a chance we’ll see some reviews sooner, not to mention possible early leaks.
