Q&A: Why Does Nvidia Make Larger GPUs If They Aren't Needed for Gaming?
The recent increase in the power, size, and VRAM capacity of high-performance Nvidia GPUs is primarily driven by the demands of the Machine Learning (ML) community, not just gaming. Achieving optimal model convergence, especially when handling data imbalance or outliers during large-scale training, requires significantly larger batch sizes and massive amounts of VRAM.
Key takeaways
High-performance GPU development is driven over 90% by the needs of ML operations and research, rather than the gaming market.
For stable convergence in large model training, current available VRAM capacity is insufficient when dealing with data imbalance or outliers.
To increase batch size for efficient ML learning (e.g., from 42 to 420), massive memory like a minimum 3x Nvidia A100 GPU combination and over 240Gb is required.
Future models (with 5 times the parameters) and high-resolution data are estimated to require approximately 500Gb of VRAM.
