Performance Analysis

FP16 dense performance places the B300 at 2250 TFLOPS against the A16 at 17.9 TFLOPS while FP16 with sparsity places the B300 at 4500 TFLOPS against the A16 at 35.9 TFLOPS. The FP32 rating of 75 TFLOPS on the B300 versus 4.5 TFLOPS on the A16 indicates capacity for larger training and inference workloads in those precisions. Memory bandwidth of 8000 GB/s on the B300 versus 200 GB/s on the A16 supports larger batch sizes in memory intensive operations.

When to Choose the A16

The A16 fits deployments that require a 250W TDP and PCIe form factor with 16 GB GDDR6 memory. Its INT8 dense rating of 35.9 TOPS handles moderate inference loads without the 1400W power demand of the B300.

When to Choose the B300

The B300 fits deployments that require 8000 GB/s bandwidth and between 262 GB and 288 GB HBM3e memory. Its FP16 dense rating of 2250 TFLOPS supports large scale workloads beyond the 17.9 TFLOPS FP16 dense of the A16.

How this page is made

  • Specifications come from the NVIDIA, AMD and Intel datasheets for the A16 and the B300. Dense and sparse throughput are listed separately.
  • Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
  • The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
