Performance Analysis
FP16 dense performance measures 40.6 TFLOPS on the RTX 3070 and 59.5 TFLOPS on the RTX 3080, maintaining the same 1.47 times ratio observed in FP32. FP16 with sparsity reaches 81.3 TFLOPS on the RTX 3070 and 119 TFLOPS on the RTX 3080. The doubled FP16 dense figure relative to FP32 on each card supports mixed-precision training and inference without additional hardware changes. Memory bandwidth of 760 GB/s on the RTX 3080 versus 448 GB/s on the RTX 3070 permits larger batch sizes during model execution. INT8 dense throughput of 238 TOPS on the RTX 3080 exceeds the 162.6 TOPS of the RTX 3070 by the same 1.47 times factor.

When to Choose the RTX 3070
The RTX 3070 suits deployments where power limits constrain operation at 220W TDP. Its 8 GB capacity handles inference workloads that fit within that memory envelope while drawing less power than the 320W TDP of the RTX 3080. Users select the RTX 3070 when FP32 at 20.3 TFLOPS meets throughput targets without requiring additional bandwidth.
When to Choose the RTX 3080
FP32 performance at 29.8 TFLOPS and FP16 dense at 59.5 TFLOPS accelerate both training and inference relative to the lower figures on the RTX 3070. The card serves scenarios where the 1.47 times compute increase justifies the higher 320W TDP.
Use Cases
The RTX 3080 supplies 29.8 TFLOPS FP32 and 760 GB/s bandwidth that exceed the RTX 3070 values for larger model training runs.
FP16 dense performance at 59.5 TFLOPS combined with 10-12 GB VRAM supports higher throughput than the 40.6 TFLOPS and 8 GB on the RTX 3070.
The RTX 3080 provides 238 TOPS INT8 dense and greater memory bandwidth that accommodate fine-tuning workloads beyond the RTX 3070 limits.
Both cards deliver sufficient FP16 dense performance for image generation tasks when memory fits within 8 GB or 10-12 GB.
FP32 at 29.8 TFLOPS and 760 GB/s bandwidth on the RTX 3080 enable faster execution of compute kernels compared with 20.3 TFLOPS and 448 GB/s.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3070 and the RTX 3080. 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.
