Performance Analysis

The B200's FP16 performance of 4500 TFLOPS vastly outpaces the L4's 121 TFLOPS, enabling up to 37 times faster deep learning training where half-precision computations dominate. This delta translates to handling larger models and datasets in real-world scenarios, such as training billion-parameter LLMs, while the L4 suits smaller-scale training limited by its compute ceiling. FP32 metrics reinforce this: 90 TFLOPS for the B200 versus 30.3 TFLOPS for the L4, a roughly threefold advantage for general-purpose simulations.

Memory bandwidth defines batch size capabilities: the B200's 8000 GB/s supports massive batches for stable training gradients, avoiding out-of-memory errors on models exceeding 24 GB, unlike the L4's 300 GB/s constraint. For inference, FP8 performance shines brightest on the B200 at 9000 TFLOPS against 242 TFLOPS, accelerating quantized deployments. Power draw underscores trade-offs, with the B200's 1000W TDP demanding robust cooling versus the L4's efficient 72W.

These specs impact throughput directly: higher bandwidth and VRAM on the B200 reduce latency in memory-bound tasks, while the L4 excels in power-constrained, low-utilization inference.
