Performance Analysis

The RTX 3080 outperforms the RTX 3060 significantly in compute capability: 29.8 TFLOPS in both FP16 and FP32 compared to 12.7 TFLOPS. This delta translates to roughly 2.3 times faster processing for machine learning training and inference, enabling the RTX 3080 to handle larger models or datasets in less time. For training, higher FP16 performance accelerates gradient computations; for inference, FP32 superiority speeds up forward passes in production deployments.

Memory bandwidth defines workload feasibility: RTX 3080's 760 GB/s doubles the RTX 3060's 360 GB/s, supporting larger batch sizes without bottlenecks. This matters for training where high bandwidth prevents memory saturation during data loading. The RTX 3060's 12 GB GDDR6 VRAM matches the upper end of RTX 3080's 10 to 12 GB GDDR6X, but the latter's faster memory type enhances effective capacity for bandwidth-intensive tasks like Stable Diffusion.

Power consumption reflects these differences: RTX 3080 draws 320W TDP versus 170W for RTX 3060, implying higher operational costs in prolonged cloud sessions but justified by performance gains.

When to Choose the RTX 3060

The RTX 3060 excels in cost-sensitive scenarios with light to moderate workloads. Its pricing from $0.03 per hour and 170W TDP make it ideal for prototyping, small-scale inference, or fine-tuning models under 12 GB VRAM, where 12.7 TFLOPS suffices without overprovisioning. Developers on tight budgets across 12 cloud offers benefit from this efficiency.

Entry-level scientific computing or Stable Diffusion at reduced resolutions favor the RTX 3060, as 360 GB/s bandwidth handles modest batch sizes effectively.

When to Choose the RTX 3080

The RTX 3080 suits high-throughput applications demanding superior compute. With 29.8 TFLOPS and 760 GB/s bandwidth, it accelerates LLM training and large-batch inference, justifying $0.06 per hour starting price across 10 offers despite 320W TDP.

Users processing complex models or high-resolution Stable Diffusion select the RTX 3080 for its GDDR6X memory advantage, enabling workloads infeasible on lesser bandwidth.

Use Cases

LLM Training
RTX 3080

RTX 3080's 29.8 TFLOPS FP16 performance doubles RTX 3060's 12.7 TFLOPS, accelerating gradient computations for large language models. Higher 760 GB/s bandwidth enables bigger batches without memory stalls.

LLM Inference
RTX 3080

The 29.8 TFLOPS FP32 on RTX 3080 speeds up forward passes by over 2x compared to 12.7 TFLOPS on RTX 3060. This reduces latency for production-scale serving.

Fine-tuning
Either

Both offer 12 GB VRAM maximum, sufficient for most fine-tuning tasks. RTX 3060 suffices at lower cost for smaller models, while RTX 3080 accelerates via 29.8 TFLOPS.

Stable Diffusion
RTX 3080

RTX 3080's 760 GB/s bandwidth and GDDR6X handle high-resolution image generation better than RTX 3060's 360 GB/s. Compute at 29.8 TFLOPS reduces iteration times.

Scientific Computing
RTX 3060

RTX 3060's 170W TDP and $0.03 per hour pricing fit budget simulations with 12.7 TFLOPS. It matches needs without RTX 3080's excess 320W power draw.
