Performance Analysis
The FP16 dense figure of 59.5 TFLOPS on the RTX 3080 stands against the FP16 dense figure of 61.7 TFLOPS on the RTX 5070 while the FP16 figure with sparsity of 119 TFLOPS on the RTX 3080 stands against the FP16 figure with sparsity of 123.5 TFLOPS on the RTX 5070. The FP16 dense to FP32 ratio equals 2.0 on the RTX 3080 and equals 2.0 on the RTX 5070 so both GPUs double throughput when moving from FP32 to FP16 dense workloads in training or inference. Memory bandwidth of 760 GB/s on the RTX 3080 exceeds the 672 GB/s figure on the RTX 5070 and therefore supports larger batch sizes in memory bound operations. The INT8 dense rating of 238 TOPS on the RTX 3080 stands against the INT8 dense rating of 246.9 TOPS on the RTX 5070.

When to Choose the RTX 3080
The RTX 3080 suits workloads that require the higher memory bandwidth of 760 GB/s to maintain throughput in data movement heavy tasks. Its FP16 dense rating of 59.5 TFLOPS remains competitive when power limits allow the 320W TDP.
When to Choose the RTX 5070
The RTX 5070 suits workloads that benefit from the lower TDP of 250W and the higher FP16 dense rating of 61.7 TFLOPS. Its VRAM range up to 16 GB supports larger models than the 10-12 GB range on the RTX 3080.
Use Cases
The FP16 dense rating of 61.7 TFLOPS on the RTX 5070 exceeds the 59.5 TFLOPS rating on the RTX 3080.
The FP16 figure with sparsity of 123.5 TFLOPS on the RTX 5070 exceeds the 119 TFLOPS rating on the RTX 3080.
Both GPUs deliver FP32 performance near 30 TFLOPS and support similar dense FP16 throughput.
The INT8 dense rating of 246.9 TOPS on the RTX 5070 exceeds the 238 TOPS rating on the RTX 3080.
The memory bandwidth of 760 GB/s on the RTX 3080 exceeds the 672 GB/s rating on the RTX 5070.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3080 and the RTX 5070. 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.
