Yesterday in Warsaw, Poland, NVIDIA held an event called NVIDIA Partner Days. I've been a journalist in this field for 20 years, and I was invited to attend. I asked an engineer from NVIDIA about what else the upcoming Switch 2 might be capable of. He told me it would "definitely surprise us," and that NVIDIA provided a very custom chip with elements not only from the Ampere architecture, but also from newer ones.
The T239 chip in the Nintendo Switch 2 is a heavily modified design. I don't know how many CUDA cores it has, but I do know the memory bandwidth is higher than 102 GB/s. The fundamental base is the Ampere architecture, known from the RTX 30 series, but for example, the RT and Tensor cores come from the RTX 40 series.
Overall, the engineer couldn't share too many details. Before we wrapped up, I asked him what console the Switch 2 could be compared to. He said it's "definitely more powerful" than the PS4/XOne, and in his view, with DLSS support, it will offer prettier games and more features than the Xbox Series S. He believes it's absolutely capable of running any multiplatform game available on the market that works on XSX/S or PS5.
