Performance Analysis
The RTX 3090 Ti delivers 71 TFLOPS dense FP16 and 35.6 TFLOPS FP32 while the RTX 5070 Ti delivers 61.7 TFLOPS dense FP16 and 30.9 TFLOPS FP32. The higher dense FP16 rating on the RTX 3090 Ti supports larger batch sizes during training workloads that rely on dense tensor operations. Memory bandwidth reaches 936 GB/s on the RTX 3090 Ti family versus 672 GB/s on the RTX 5070 Ti family so the RTX 3090 Ti sustains higher throughput for memory intensive inference steps that use the same dense FP16 mode. Sparse FP16 figures stand at 142 TFLOPS for the RTX 3090 Ti family and 123.5 TFLOPS for the RTX 5070 Ti family allowing consistent comparison only when sparsity is applied equally to both.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3090 Ti and the RTX 5070 Ti. 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.
