Roundup: Exceptional performance but Nvidia is still better at ray tracing

AMD has lifted the NDA on Radeon RX 7900 XTX and RX 7900 XT reviews and the cards should be available as of tomorrow, launching at $899 and $999, respectively.

The long-awaited RDNA3 graphics cards are finally put to the test, and these bring significant improvements compared to the previous generation cards, in both performance, as well as power efficiency.

AMD is kicking off its RDNA3 era with two SKUs, the flagship Radeon RX 7900 XTX and the Radeon RX 7900 XT.

The Radeon RX 7900 XTX brings a fully-enabled Navi 31 GPU, packing 96 CUs and 96MB of AMD Infinity Cache. This adds up to 6,144 Stream Processors, 96 Ray Accelerators, 384 TMUs, and 192 ROPs. It has 24GB of 20Gbps GDDR6 memory on a 384-bit memory interface. The game clock is set at 2.3GHz and it boosts up to 2.5GHz. The TBP (Total Board Power) is set at 355W and it needs two 8-pin PCIe power connectors.

The Radeon RX 7900 XT is based on the same Navi 31 GPU, but with 84 CUs, and 80MB of AMD Infinity Cache. This leaves the Radeon RX 7900 XT with 5,376 Stream Processors, 336 TMUs, and the same 192 ROPs. It comes with 20GB of 20Gbps GDDR6 memory on a bit narrower 320-bit memory interface. Its TBP is set at 315W so it still needs two 8-pin PCIe power connectors.

Performance-wise, the RX 7900 XTX does pretty well against the Nvidia Geforce RTX 4080, offering pretty similar performance and even pushing slightly ahead at higher resolutions. With ray tracing, Nvidia takes the lead, and while AMD has significantly improved its ray tracing performance compared to the previous generation, Nvidia is still ahead, with RTX 4080 leading by around 10 to 15 percent.

The RTX 4090 is still ahead in both raster and RT performance, but the price difference is significant as well.

The RX 7900 XT performance is as expected, around 10 to 20 percent lower than the RX 7900 XTX, especially at higher resolutions. As it is just $100 cheaper, those gaming at 4K might consider going for the flagship. In any case, it is still a great card at $899, matching RTX 3090 Ti and being just around 10-15 percent slower than the Geforce RTX 4080, which is still a $1,200 priced graphics card.

Tomorrow, when these cards become available, it is left to be seen if these will actually be available at MSRP, and what will be the price premium on custom cards from AIB partners.

In any case, the ball is now in Nvidia's court, and while it can justify the price premium with ray tracing performance, there were solid rumors that we'll see a price cut for the Geforce RTX 4080.
