Performance Analysis
Dense FP16 performance reaches 165.2 TFLOPS on the RTX 4090 compared to 125 TFLOPS on the V100. This ratio of 1.32 times higher dense FP16 on the RTX 4090 supports faster training iterations and inference throughput in compatible frameworks. FP32 figures show the RTX 4090 at 82.6 TFLOPS versus 15.7 TFLOPS on the V100 which translates to over five times the throughput for precision sensitive computations. Memory bandwidth of 1008 GB/s on the RTX 4090 versus 900 GB/s on the V100 permits modestly larger batch sizes during model execution before memory constraints appear. Sparsity enabled FP16 on the RTX 4090 reaches 330.4 TFLOPS while the V100 provides no sparsity figure for direct comparison.

When to Choose the RTX 4090
The RTX 4090 suits workloads that demand the 82.6 TFLOPS FP32 rating or the 165.2 TFLOPS dense FP16 rating. Its 24 GB memory capacity and 1008 GB/s bandwidth further support larger data sets in single GPU configurations.
When to Choose the V100
The V100 fits environments where the 300W TDP rating reduces power draw relative to the 450W TDP of the RTX 4090. NVLink interconnect availability on the V100 also enables multi GPU scaling in systems that require that specific fabric.
Use Cases
The RTX 4090 provides 165.2 TFLOPS dense FP16 which exceeds the V100 125 TFLOPS dense FP16 rating.
Dense FP16 throughput at 165.2 TFLOPS on the RTX 4090 supports higher tokens per second than the V100 125 TFLOPS.
FP32 performance of 82.6 TFLOPS on the RTX 4090 enables more efficient gradient updates than the V100 15.7 TFLOPS.
The RTX 4090 memory bandwidth of 1008 GB/s exceeds the V100 900 GB/s for image generation batches.
The V100 TDP of 300W lowers power requirements compared to the RTX 4090 450W TDP in sustained runs.
