Performance Analysis

The FP16 dense rating reaches 40.6 TFLOPS on the RTX 3070 and 209.5 TFLOPS on the RTX 5090 while FP16 with sparsity reaches 81.3 TFLOPS versus 419 TFLOPS. This gap means training and inference steps complete faster on the higher figure when operating in dense mode or when sparsity is enabled. Memory bandwidth of 1792 GB/s versus 448 GB/s supports larger batch sizes before memory saturation occurs. The FP32 rating of 104.8 TFLOPS versus 20.3 TFLOPS further widens throughput differences for single precision operations.

When to Choose the RTX 3070

The RTX 3070 suits workloads that remain within 8 GB VRAM and that prioritize the 220 W TDP limit. Inference on compact models or fine tuning tasks that do not exceed the 40.6 TFLOPS FP16 dense rating benefit from lower power draw.

When to Choose the RTX 5090

The RTX 5090 suits workloads that require 32 GB VRAM and that benefit from the 1792 GB/s bandwidth together with 209.5 TFLOPS FP16 dense performance. Training or inference on larger models that exceed 8 GB capacity gain from the higher FP32 rating of 104.8 TFLOPS.

Use Cases

LLM Training
RTX 5090

The 32 GB VRAM and 209.5 TFLOPS FP16 dense rating exceed the 8 GB and 40.6 TFLOPS limits of the alternative.

LLM Inference
RTX 5090

Higher memory bandwidth of 1792 GB/s and FP16 dense performance of 209.5 TFLOPS support larger batch sizes than 448 GB/s and 40.6 TFLOPS.

Fine-tuning
Either

Models that fit in 8 GB can use the 40.6 TFLOPS FP16 dense rating while larger models require the 32 GB capacity.

Stable Diffusion
RTX 5090

The 32 GB GDDR7 memory and 1792 GB/s bandwidth accommodate higher resolution generations beyond the 8 GB limit.

Scientific Computing
RTX 5090

FP32 performance of 104.8 TFLOPS combined with 32 GB VRAM exceeds the 20.3 TFLOPS and 8 GB specifications.

How this page is made

  • Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3070 and the RTX 5090. 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.
