Performance Analysis
The FP16 dense figure of 2250 TFLOPS on the B200 exceeds the 97.5 TFLOPS dense FP16 on the RTX 4080 by a factor derived directly from those values and supports larger batch sizes during training or inference workloads. Memory bandwidth of 8000 GB/s on the B200 versus 717 GB/s on the RTX 4080 allows the B200 to sustain higher data movement rates that scale with its 180-192 GB capacity. FP32 performance stands at 75 TFLOPS on the B200 against 48.7 TFLOPS on the RTX 4080 while FP8 dense reaches 4500 TFLOPS on the B200 compared to 194.9 TFLOPS dense FP8 on the RTX 4080.

When to Choose the B200
The B200 suits large scale LLM training or scientific computing that requires 180-192 GB HBM3e memory and 2250 TFLOPS FP16 dense to handle extensive model states. Its 8000 GB/s bandwidth and 1000W TDP further enable sustained operation in multi GPU NVLink configurations for those workloads.
When to Choose the RTX 4080
The RTX 4080 fits inference or fine tuning tasks that operate within 16 GB GDDR6X limits and 97.5 TFLOPS FP16 dense while drawing only 320W TDP through PCIe form factor. Its 717 GB/s bandwidth suffices for smaller batch sizes in such scenarios.
Use Cases
The B200 supplies 2250 TFLOPS FP16 dense and 180-192 GB memory that exceed the RTX 4080 97.5 TFLOPS FP16 dense and 16 GB capacity.
The B200 provides 4500 TFLOPS FP8 dense along with 8000 GB/s bandwidth that support larger concurrent requests than the RTX 4080 194.9 TFLOPS FP8 dense.
The B200 2250 TFLOPS FP16 dense and 180-192 GB VRAM accommodate full parameter updates that the RTX 4080 97.5 TFLOPS FP16 dense and 16 GB cannot match.
The RTX 4080 48.7 TFLOPS FP32 and 320W TDP deliver adequate performance for image generation within its 16 GB limit at lower power draw.
The B200 75 TFLOPS FP32 and 8000 GB/s bandwidth handle large matrix operations that surpass the RTX 4080 48.7 TFLOPS FP32 and 717 GB/s bandwidth.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the B200 and the RTX 4080. 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.
