AMD had jumped in front just as Nvidia got on the stage to launch the 40 series. Nvidia is launching some new GeForce RTX cards at the GTC presentation today, but AMD is looking into the future. They have announced that they will launch RDNA 3 on November 3. It will be a big showdown to claim honors among the best graphics card this fall. AMD had RDNA 3 into a new cycle for the second time this week. Yesterday they published a blog post about performance per watt gains and efficiency in Radeon GPUs based on rDNA technology.
Rumors suggest that RDNA 3 will be offered up to 96 compute units with 12,288 shaders and would up 50% more performance per watt than the previous generations. It will be moving to a GPU chipset architecture as well. This would revolutionize GPUs just as the company’s chiplet-based Ryzen lineup had completely changed the CPU landscape.
It is also expected that the ray tracing hardware would also get a serious improvement. This would include the dedicated BVH hardware that both Intel and Nvidia offer. This move to chipsets would be a move away from how GPUs are currently made from a single piece of silicon. This will allow for lower cost paired with a more scalable architecture. This will also allow AMD to race out to new smaller process nodes before the other companies.
We have been expecting this news for quite some time. AMD’s next generation RDNA 3 graphic cards will be unveiled in November, and the company is already teasing impressive performance per watt from its brand new GPU. Lisa Su is the CEO of AMD. She had confirmed that AMD would pursue a chipset architecture for its RDNA 3 GPUs. It is rumored that this approach would be quite radical for GPU development in the longer run. Some do call it wishful thinking also.
It seems most probably these cards would use chipsets to combine a GPU block with the necessary I/O die, which is required to hook it up to a wider system and extract top performance.
