NVIDIA saves the possibility of using chipsets for better times

NVIDIA saves the possibility of using chipsets for better times

If you believe the statements of NVIDIA chief scientific adviser Bill Dally in an interview with the resource Semiconductor Engineering, the company developed the technology for creating a multi-core processor with a multi-chip layout six years ago, but is still not ready to use it in mass production. On the other hand, the company also started to place HBM-type memory chips in the immediate vicinity of the GPU several years ago, so it cannot be blamed for completely ignoring the “modelers for chipsets”.

Until now, it has been argued that the prototype of the 36-core processor with RISC-V architecture from NVIDIA was needed to develop methods for scaling performance in computing accelerators, as well as to prepare for the introduction of new layout solutions. All this experience, according to representatives of NVIDIA, may be required by the company at a time when it becomes economically feasible to create graphic processors from separate "chipsets". So far this moment has not come, and NVIDIA does not even undertake to predict when this will happen.

Bill Dally also noted that relying on lithography for scaling processor performance has long been pointless. Between two adjacent stages of the technological process, the increase in the speed of transistors is measured 20%, in the best case, and architectural and software innovations can increase the speed of graphic processors several times. In this sense, architecture dominates lithography from the point of view of NVIDIA.

The founder of NVIDIA Jensen Huang (Jen-Hsun Huang) has repeatedly confirmed this position in his statements. Until now, he has been doing his best to prove the progressive approach to creating monolithic crystals, scornfully speaking to competitors who are chasing new technological processes, and even compared the “chipsets" as a joke with the consonant chewing gum ("chiclets"), explaining that he likes only last interpretation of the term. Nevertheless, the statements of NVIDIA specialists closer to the development of products allow us to believe that the company will eventually switch to multi-chip layout. Intel, for example, does not hide its intentions to make the 7-nm graphics processor multi-chip, using the Foveros layout. AMD is actively using "chipsets" in the creation of central processors, but so far in the graphics segment it has limited itself to "dividing" HBM2-type memory.
