NVIDIA could present the Hopper architecture within the framework of the GTC 2022, a very important event that will take place next week, and that will serve as the stage for the green giant’s key announcements related to its new generation of high-performance professional GPUs.
In this sense, it is important to make it clear that Hopper will be, according to the latest information, an architecture that will be focused on the professional sector, which means that, in theory, it would only be used to shape new graphics accelerators focused on data centers and supercomputers for high performance computing. In short, these solutions will be the successors of the current NVIDIA A100, based on the GA100 core.
The most important thing we can say about NVIDIA’s Hopper architecture is that it will, in theory, mark the leap to a MCM core designie the green giant will combine two GPUs to create a super GPU, resulting in a multi-chip design. Uniting chips has become the way forward for industry giants to overcome the limitations of monolithic core designs, we’ve already seen it in Ryzen processors, and AMD has also recently made the leap to such designs with its new Instinct 200 series graphics accelerators.
We still have many doubts about the possible specifications that the GH100 graphics core would have, the most powerful within the new Hopper architecture, but everything seems to indicate that it will be made up of two chiplets, and that each would have 144 SM units. If this is confirmed, each chiplet would have 18,432 shaders, which means that the NVIDIA H100 graphics accelerator could have up to 36,864 shaders, an impressive figure if we take into account that the NVIDIA A100 only has 6,912 shaders.
The rest of its specifications are a mystery, but it is rumored that this graphics accelerator would have 140,000 million transistors, would have a 6,144-bit bus, would have 128 GB of HBM3 memory and its TGP would be between 250 and 500 watts. This wide estimate is a clear sign that there are still many doubts surrounding Hopper. The launch of it would take place, in theory, before the end of this year.
