Performance Analysis
The RTX 4080 delivers 97.5 TFLOPS dense FP16 compared with 40.6 TFLOPS dense FP16 on the RTX 3070 yielding a 2.4 times increase in dense FP16 performance. The same ratio holds for FP32 where the RTX 4080 reaches 48.7 TFLOPS against 20.3 TFLOPS on the RTX 3070. Training benefits from the higher dense FP16 figure because gradient computations and forward passes execute faster while inference gains similarly from the dense FP16 throughput when batch sizes remain constant. Sparsity comparisons remain separate with the RTX 4080 at 195 TFLOPS sparse FP16 versus 81.3 TFLOPS sparse FP16 on the RTX 3070.

When to Choose the RTX 3070
The RTX 3070 suits environments where power draw must stay at 220 W rather than 320 W. Workloads that fit within 8 GB VRAM and require only 40.6 TFLOPS dense FP16 avoid the extra TDP of the RTX 4080. Scientific computing tasks that rely on the 162.6 TOPS dense INT8 rating of the RTX 3070 complete without excess power consumption.
When to Choose the RTX 4080
The RTX 4080 fits workloads that require 16 GB VRAM and 97.5 TFLOPS dense FP16 to accommodate larger models or batches. Inference and training jobs that scale with the 717 GB/s bandwidth finish faster than on the RTX 3070. Fine-tuning sessions benefit from the doubled memory capacity and the 2.4 times higher dense FP16 rating.
Use Cases
The RTX 4080 supplies 97.5 TFLOPS dense FP16 and 16 GB VRAM enabling larger models than the 40.6 TFLOPS dense FP16 and 8 GB on the RTX 3070.
The RTX 4080 reaches 97.5 TFLOPS dense FP16 and 717 GB/s bandwidth supporting higher throughput than the RTX 3070 at 40.6 TFLOPS dense FP16.
The RTX 4080 provides 16 GB VRAM and 97.5 TFLOPS dense FP16 allowing fine-tuning of models that exceed the 8 GB limit of the RTX 3070.
Both GPUs handle the workload yet the RTX 4080 completes iterations faster with 97.5 TFLOPS dense FP16 while the RTX 3070 suffices at 40.6 TFLOPS dense FP16 when power is limited to 220 W.
The RTX 3070 meets requirements at 220 W TDP and 162.6 TOPS dense INT8 without the 320 W draw of the RTX 4080.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3070 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.
