H100 vs RTX 3060

Specifications and current cloud pricing, side by side.

HoppervsAmpereUpdated 33 days ago

The H100 wins for the most common use case of LLM training because its 989 TFLOPS FP16 dense rating and 80-94 GB VRAM exceed the RTX 3060 capabilities where FP16 is not published and VRAM reaches only 8-12 GB.

Performance Analysis

The H100 achieves 989 TFLOPS FP16 dense compared to the RTX 3060 where FP16 remains not published by vendor so no direct FP16 ratio applies. This FP16 dense figure on the H100 supports larger batch processing during training and inference relative to FP32 alone. Memory bandwidth of 3350 GB/s on the H100 versus 360 GB/s on the RTX 3060 allows the H100 to sustain higher data throughput for operations that move substantial volumes between memory and compute units. FP32 comparison shows the H100 at 67 TFLOPS against 12.7 TFLOPS on the RTX 3060 indicating a substantial gap in general purpose floating point workloads.

When to Choose the H100

The H100 suits scenarios that require 80-94 GB HBM3 VRAM and 3350 GB/s memory bandwidth such as training models that exceed the capacity of smaller GPUs. Its 989 TFLOPS FP16 dense rating and 67 TFLOPS FP32 rating further support intensive scientific computing tasks that benefit from high throughput interconnects including NVLink.

When to Choose the RTX 3060

The RTX 3060 fits environments where 170W TDP and PCIe form factor suffice for lighter workloads that stay within 8-12 GB GDDR6 VRAM limits. Its 12.7 TFLOPS FP32 performance handles basic inference or fine tuning on modest datasets without demanding the higher power or specialized interconnects of the H100.

Use Cases

LLM Training
H100

The H100 supplies 989 TFLOPS FP16 dense and 80-94 GB HBM3 VRAM that accommodate large model training while the RTX 3060 FP16 remains not published by vendor.

LLM Inference
H100

The H100 delivers 1979 TFLOPS FP16 with sparsity and 3350 GB/s bandwidth that sustain high throughput inference on large models.

Fine-tuning
H100

How this page is made

  • Specifications come from the NVIDIA, AMD and Intel datasheets for the H100 and the RTX 3060. 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.
