Performance Analysis
The gap between 989 TFLOPS dense FP16 on the GH200 and 112.6 TFLOPS dense FP16 on the RTX 5080 shows that the GH200 completes larger scale training and inference operations within identical time windows. For inference the 989 TFLOPS dense FP16 figure supports bigger models without any sparsity applied. Memory bandwidth of 4000 GB/s on the GH200 versus 960 GB/s on the RTX 5080 enables larger batch sizes during model processing. When sparsity is applied the 1979 TFLOPS FP16 with sparsity on the GH200 exceeds the 225.1 TFLOPS FP16 with sparsity on the RTX 5080 by a substantial margin. The FP32 figures of 67 TFLOPS on the GH200 and 56.3 TFLOPS on the RTX 5080 remain closer for single precision tasks.

When to Choose the GH200
The GH200 suits scenarios that demand 96 GB VRAM capacity for large models in scientific computing. Its 4000 GB/s bandwidth supports data intensive operations that exceed the capabilities of the 16 GB VRAM on the RTX 5080.
When to Choose the RTX 5080
The RTX 5080 fits environments where 360W power consumption is a constraint and 16 GB GDDR7 suffices for smaller inference tasks. Its PCIe form factor allows easier integration in standard systems compared to the SXM form factor of the GH200.
Use Cases
The 989 TFLOPS dense FP16 and 96 GB VRAM of the GH200 enable training of larger models than the 112.6 TFLOPS and 16 GB of the RTX 5080.
The 989 TFLOPS dense FP16 of the GH200 supports bigger models without sparsity compared to the 112.6 TFLOPS dense FP16 of the RTX 5080.
The 4000 GB/s memory bandwidth of the GH200 permits larger batch sizes than the 960 GB/s bandwidth of the RTX 5080.
The 360W TDP of the RTX 5080 fits power constrained setups where 16 GB GDDR7 meets the requirements.
The 67 TFLOPS FP32 and 96 GB VRAM of the GH200 handle data intensive scientific workloads beyond the 56.3 TFLOPS and 16 GB of the RTX 5080.
