Performance Analysis

The FP32 performance of the RTX 5090 reaches 104.8 TFLOPS compared with 12.7 TFLOPS on the RTX 3060. This eightfold increase supports faster execution of training and inference steps that rely on single precision arithmetic. The RTX 5090 also lists dense FP16 performance at 209.5 TFLOPS. Memory bandwidth on the RTX 5090 measures 1792 GB/s against 360 GB/s on the RTX 3060. The higher bandwidth permits larger batch sizes during both training and inference without memory bottlenecks. Dense FP16 figures must be compared only against other dense FP16 figures and sparse figures only against other sparse figures when evaluating the RTX 5090.

When to Choose the RTX 3060

The RTX 3060 suits environments where power draw must stay at 170W and where models fit within 12 GB of memory. PCIe 4.0 interconnect meets requirements for many standard inference tasks that do not demand the 1792 GB/s bandwidth of newer cards.

When to Choose the RTX 5090

The RTX 5090 fits workloads that require 32 GB of memory and 104.8 TFLOPS FP32 performance. Its 1792 GB/s bandwidth and dense FP16 rating of 209.5 TFLOPS enable larger batch processing and accelerated tensor operations on Blackwell architecture.

Use Cases

LLM Training
RTX 5090

The RTX 5090 supplies 32 GB memory and 104.8 TFLOPS FP32 performance while the RTX 3060 is limited to 12 GB and 12.7 TFLOPS FP32.

LLM Inference
RTX 5090

Dense FP16 performance of 209.5 TFLOPS on the RTX 5090 supports higher throughput than the RTX 3060 can achieve with its published specifications.

Fine-tuning
RTX 5090

The 1792 GB/s memory bandwidth and 32 GB capacity on the RTX 5090 accommodate larger fine tuning batches compared with 360 GB/s and 12 GB on the RTX 3060.

Stable Diffusion
Either

Both GPUs handle image generation workloads though the RTX 5090 completes them faster due to higher FP32 and memory specifications.

Scientific Computing
RTX 5090

FP32 performance of 104.8 TFLOPS and 1792 GB/s bandwidth on the RTX 5090 accelerate scientific simulations beyond the 12.7 TFLOPS and 360 GB/s of the RTX 3060.

How this page is made

  • Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3060 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.
