Performance Analysis
The identical FP16 dense rating of 2250 TFLOPS on both the B200 and GB300 produces equivalent throughput for training workloads that rely on dense FP16 operations. Inference tasks using dense FP16 likewise experience matching performance levels between the two GPUs. Memory bandwidth remains fixed at 8000 GB per second for both models so maximum batch sizes stay comparable when memory capacity permits. The GB300 FP4 dense rating of 13500 TFLOPS exceeds the B200 FP4 dense rating of 9000 TFLOPS and therefore accelerates workloads that utilize dense FP4 arithmetic. The B200 INT8 dense rating of 4500 TOPS surpasses the GB300 INT8 dense rating of 187.5 TOPS and therefore favors integer heavy operations on the B200.

When to Choose the B200
The B200 suits environments where power limits constrain deployment because its TDP measures 1000W. Workloads that depend on high INT8 dense throughput of 4500 TOPS benefit from selection of the B200 over the GB300. Systems already configured for SXM or NVL form factors align directly with B200 hardware options.
When to Choose the GB300
The GB300 fits applications that require the larger VRAM range of 262 to 288 GB for model storage. Tasks that exploit dense FP4 performance gain from the GB300 rating of 13500 TFLOPS. Installations that accept the SXM6 form factor and higher TDP of 1400W accommodate the GB300 without issue.
Use Cases
The GB300 supplies 262 to 288 GB of HBM3e VRAM which supports larger model sizes during training compared to the B200 range of 180 to 192 GB.
The GB300 FP4 dense performance of 13500 TFLOPS accelerates inference when dense FP4 arithmetic applies while both GPUs share the same FP16 dense rating of 2250 TFLOPS.
Both GPUs deliver identical FP16 dense performance of 2250 TFLOPS and memory bandwidth of 8000 GB per second so fine tuning throughput remains comparable.
The B200 INT8 dense rating of 4500 TOPS exceeds the GB300 rating of 187.5 TOPS and therefore improves performance on integer operations common in diffusion pipelines.
The B200 TDP of 1000W reduces power draw relative to the GB300 TDP of 1400W while both maintain the same FP32 performance of 75 TFLOPS.
