Performance Analysis
The FP16 dense rating of 2250 TFLOPS on the B200 exceeds the FP16 dense rating of 112.6 TFLOPS on the RTX 5080 by a factor of twenty. This gap directly affects training throughput because higher dense FP16 capacity supports larger model updates per step. FP32 performance of 75 TFLOPS on the B200 versus 56.3 TFLOPS on the RTX 5080 further widens the advantage for precision sensitive workloads. Memory bandwidth of 8000 GB/s on the B200 versus 960 GB/s on the RTX 5080 permits batch sizes that scale with the twenty to one ratio in available throughput. Sparse FP16 figures follow the same pattern with 4500 TFLOPS on the B200 against 225.1 TFLOPS on the RTX 5080.

When to Choose the B200
The B200 suits large model training sessions that require 180 to 192 GB HBM3e capacity and 8000 GB/s bandwidth. Workloads that need 2250 TFLOPS dense FP16 or 4500 TFLOPS dense FP8 benefit from the 1000W TDP envelope and NVLink interconnect.
When to Choose the RTX 5080
The RTX 5080 suits inference tasks that fit within 16 GB GDDR7 and run at 112.6 TFLOPS dense FP16. Its 360W TDP and PCIe 5.0 interface fit power limited or single node environments that do not require the 8000 GB/s bandwidth of the B200.
Use Cases
The B200 supplies 2250 TFLOPS dense FP16 and 180 to 192 GB HBM3e that allow training runs beyond the 16 GB limit of the RTX 5080.
The RTX 5080 delivers 112.6 TFLOPS dense FP16 at 360W TDP for inference workloads that remain inside 16 GB GDDR7 capacity.
Fine-tuning benefits from the B200 4500 TFLOPS dense FP8 and 8000 GB/s bandwidth that accommodate larger adapter sets than the RTX 5080 225.1 TFLOPS dense FP8.
Stable Diffusion fits the RTX 5080 16 GB GDDR7 and 960 GB/s bandwidth for generation tasks that do not need the 1000W envelope of the B200.
Scientific workloads utilize the B200 75 TFLOPS FP32 and 8000 GB/s bandwidth for simulations that exceed the 56.3 TFLOPS FP32 of the RTX 5080.
Frequently Asked Questions
What is the memory difference between B200 and RTX 5080?▾
The B200 contains 180 to 192 GB HBM3e while the RTX 5080 contains 16 GB GDDR7. This capacity gap determines which models fit without partitioning.
How does FP16 performance compare between the two GPUs?▾
Dense FP16 reaches 2250 TFLOPS on the B200 and 112.6 TFLOPS on the RTX 5080. Sparse FP16 reaches 4500 TFLOPS on the B200 and 225.1 TFLOPS on the RTX 5080.
Which GPU offers higher memory bandwidth?▾
The B200 provides 8000 GB/s bandwidth while the RTX 5080 provides 960 GB/s bandwidth. The twenty to one ratio affects achievable batch sizes in memory bound kernels.
What TDP values apply to each GPU?▾
The B200 lists a 1000W TDP and the RTX 5080 lists a 360W TDP. Power delivery infrastructure must match these ratings.
Does the B200 support NVLink?▾
The B200 includes NVLink interconnect while the RTX 5080 uses PCIe 5.0. Multi GPU scaling therefore follows different topology rules.
Which architecture generation do both GPUs share?▾
Both the B200 and RTX 5080 belong to the Blackwell generation. Their release years differ with the B200 in 2024 and the RTX 5080 in 2025.
