B300 vs RTX PRO 6000

The B300 achieves 2250 TFLOPS FP16 dense compared with 503.8 TFLOPS FP16 dense on the RTX PRO 6000. This fourfold difference in dense FP16 throughput allows the B300 to sustain substantially larger batch sizes during both training and inference when memory bandwidth of 8000 GB/s is available. The RTX PRO 6000 in turn records 126 TFLOPS FP32 which exceeds the 75 TFLOPS FP32 of the B300 and therefore favors precision sensitive scientific workloads that rely on dense FP32 operations.

The B300 suits deployments that require 2250 TFLOPS FP16 dense or 4500 TFLOPS FP8 dense together with memory capacity between 262 GB and 288 GB. Its 1400 W TDP and SXM6 form factor further align with rack scale systems that incorporate NVLink interconnects.

Choose the RTX PRO 6000 for single GPU inference and fine tuning of anything that fits in 96 GB of GDDR7, for image and video generation, and for FP32 heavy code, where its 126 TFLOPS of FP32 is actually higher than the 75 TFLOPS of the B300. Its 1007.6 TFLOPS of dense FP8 and 1792 GB/s of bandwidth serve mid sized models comfortably, and as a 600W PCIe 5.0 card it is easy to find in single card listings. Do not pick it for multi GPU training: it has no NVLink, so scaling across cards goes over PCIe and the 4.5 times bandwidth gap to the B300 compounds.
