Performance Analysis
The B300 provides FP16 dense performance at 2250 TFLOPS while no FP16 figure appears for the Quadro P6000. FP32 performance reaches 75 TFLOPS on the B300 against 12.6 TFLOPS on the Quadro P6000. The 8000 GB/s bandwidth on the B300 versus 432 GB/s on the Quadro P6000 permits substantially larger batch sizes during training and inference operations. FP16 dense throughput on the B300 supports faster execution of matrix operations compared with FP32 execution on the Quadro P6000. Memory capacity between 262 and 288 GB on the B300 accommodates models that exceed the 24 GB limit of the Quadro P6000. These differences translate to reduced iteration times on the B300 for precision formats that both GPUs can execute.

When to Choose the B300
The B300 suits LLM training workloads that require between 262 and 288 GB memory capacity together with 2250 TFLOPS FP16 dense performance. Fine tuning operations scale effectively when memory bandwidth reaches 8000 GB/s as listed for the B300.
When to Choose the Quadro P6000
The Quadro P6000 fits environments constrained to 250W TDP power envelopes and PCIe 3.0 interconnects. Scientific computing workloads that rely solely on 12.6 TFLOPS FP32 performance operate within the limits of the Quadro P6000 without requiring newer form factors.
Use Cases
The B300 supplies 2250 TFLOPS FP16 dense performance and between 262 and 288 GB memory that exceed the 24 GB limit of the Quadro P6000.
FP8 dense performance at 4500 TFLOPS on the B300 combined with 8000 GB/s bandwidth supports larger batch processing than the Quadro P6000 can achieve.
Memory capacity between 262 and 288 GB on the B300 permits fine tuning of models that surpass the 24 GB VRAM of the Quadro P6000.
The B300 FP16 dense rating of 2250 TFLOPS accelerates diffusion model steps beyond the FP32 only rating of 12.6 TFLOPS on the Quadro P6000.
The Quadro P6000 delivers 12.6 TFLOPS FP32 within a 250W TDP while the B300 offers 75 TFLOPS FP32 for higher throughput when power limits allow.
