Performance Analysis

The B200 vastly outperforms the RTX 3060 in FP16 at 4500 TFLOPS compared to 12.7 TFLOPS: this gap accelerates deep learning training, where FP16 precision suffices for most models, reducing iteration times dramatically. For FP32 tasks like simulations, the B200 delivers 90 TFLOPS against 12.7 TFLOPS, enabling complex scientific computations faster. The FP8 capability of 9000 TFLOPS on the B200 optimizes inference for quantized large language models, a feature absent or minimal on the RTX 3060.

Memory differences profoundly impact workloads: the B200's 192 GB HBM3e VRAM supports batch sizes for models exceeding 100 billion parameters, while 12 GB GDDR6 on the RTX 3060 limits to small batches or model sharding. Bandwidth at 8000 GB/s versus 360 GB/s ensures the B200 sustains data throughput for training loops, minimizing bottlenecks in memory-bound operations like transformer attention. These specs translate to the B200 handling enterprise-scale AI, whereas the RTX 3060 suits prototyping or edge deployment.
