Performance Analysis
The FP16 dense performance of 40.6 TFLOPS on the RTX 3070 versus 61.7 TFLOPS on the RTX 5070 indicates that the RTX 5070 processes matrix operations in training and inference at a higher rate when sparsity features remain disabled. The FP16 figure with sparsity of 81.3 TFLOPS on the RTX 3070 versus 123.5 TFLOPS on the RTX 5070 shows similar scaling when sparsity acceleration applies. Memory bandwidth of 448 GB/s on the RTX 3070 compared with 672 GB/s on the RTX 5070 limits sustained batch sizes during data movement in both training and inference workloads.

When to Choose the RTX 3070
The RTX 3070 suits scenarios that prioritize a TDP of 220W over higher throughput because its FP32 performance of 20.3 TFLOPS meets requirements without exceeding that power limit. Workloads that operate within 8 GB of GDDR6 memory and 448 GB/s bandwidth avoid the need for the additional capacity of the RTX 5070.
When to Choose the RTX 5070
The RTX 5070 suits workloads that require FP16 dense performance of 61.7 TFLOPS and memory bandwidth of 672 GB/s to support larger batch sizes. Its FP32 performance of 30.9 TFLOPS combined with between 12 and 16 GB of GDDR7 memory enables scaling beyond the limits of the RTX 3070.
Use Cases
The RTX 5070 supplies FP16 dense performance of 61.7 TFLOPS and memory bandwidth of 672 GB/s that exceed the 40.6 TFLOPS and 448 GB/s of the RTX 3070.
The RTX 5070 delivers FP16 dense performance of 61.7 TFLOPS along with between 12 and 16 GB of memory that support larger inference batches than the RTX 3070.
The RTX 5070 provides INT8 dense performance of 246.9 TOPS and FP16 dense performance of 61.7 TFLOPS that surpass the corresponding figures on the RTX 3070.
The RTX 5070 achieves FP16 dense performance of 61.7 TFLOPS with memory bandwidth of 672 GB/s that improve throughput over the 40.6 TFLOPS and 448 GB/s of the RTX 3070.
The RTX 3070 operates at a TDP of 220W while delivering FP32 performance of 20.3 TFLOPS that meets requirements without the 250W TDP of the RTX 5070.
