This week, AMD will unveil its new Radeon based on RDNA 3. They will have the difficult task of competing with Nvidia’s GeForce RTX 4000.
The stakes are enormous. This Thursday, AMD is to present its new generation of RDNA 3 graphics cards at a special conference. This is the response to the GeForce RTX 4000 Ada Lovelace which made a strong impression on us, especially during our test of the RTX 4090.
With the fairly high prices announced by Nvidia, but also a nice boost in graphics power and interesting technologies like DLSS 3, AMD has both a boulevard to seriously compete with its rival, and at the same time real mountains to overcome. .
A few days before the presentation, rumors and leaks are multiplying around the Radeon RX 7000. Let’s take a look at what we already know.
Launch in December
If this Thursday, November 3, AMD will unveil its Radeon RX 7000, the commercial launch should not take place before December. In any case, this is what the account Greymon55, a specialist in rumors surrounding the next graphics cards (and obviously a fan of Digimon), says.
It should be sometime between December 1-5.

Radeon RX 7900XT and Radeon RX 7900XTX
Two product names have been leaked for the moment: the Radeon RX 7900 XT which would represent AMD’s top of the range, while the Radeon RX 7900 XTX should push RDNA 3 to its limits.
The Radeon RX 7900 XTX would offer no less than 12288 Stream Processors associated with 24 GB of GDDR6 at 20 Gbit/s and 96 MB of Infinity Cache.
The Radeon RX 7900 XT would make do with 10752 Stream Processors with 20 GB of GDDR6.
For comparison, the Radeon RX 6950 XT, the most powerful card under RDNA 2 at AMD today, offers only 5120 Stream Processors. Without taking into account the optimizations of the new architecture, the raw power gain should therefore be substantial.
Photos of the graphics cards have started circulating on the web. As expectedthey offer 8-pin power ports and avoid the maligned new 12VHPWR connector. We note that two 8-pin connectors would be sufficient, implying lower power consumption than the GeForce RTX 4090 which requires three connectors.
What about ray tracing?
The RDNA 2 generation had enabled AMD to catch up with Nvidia on rasterization calculations, that is to say classic 3D without ray tracing. On the other hand, as soon as the ray tracing options were activated, the gap between AMD and Nvidia was felt.
Difficult for the moment to know if AMD will be able with RDNA 3 to catch up with its competitor on these effects which are increasingly used in modern games. With the GeForce RTX 4000s, Nvidia has given the technology a new boost, to the point of making DLSS sometimes optional.
Chiplet design
RDNA 3 graphics chips will use a chiplet architecture easier to design and manufacture. They should use a mix of TSMC N5 and N6 for manufacturing depending on the elements present on the chip.
It is this simplicity that could also allow AMD to play on prices to seriously compete with Nvidia. The ball is in Radeon’s court. See you Thursday evening from 9 p.m. to find out all the details.
