Performance Analysis
FP32 performance of 35.6 TFLOPS on the RTX 3090 exceeds the 8 TFLOPS figure on the RTX A2000 by a factor of four and a half. FP16 throughput with sparsity reaches 142 TFLOPS on the RTX 3090 against 63.9 TFLOPS with sparsity on the RTX A2000. The 936 GB/s memory bandwidth of the RTX 3090 compared with 288 GB/s on the RTX A2000 permits larger batch sizes during both training and inference passes. Dense FP16 performance of 71 TFLOPS on the RTX 3090 supports higher throughput than the sparsity-only rating available for the RTX A2000. These ratios translate into shorter iteration times on memory intensive operations when the RTX 3090 handles the workload.

When to Choose the RTX 3090
The RTX 3090 suits LLM training jobs that require the full 24 GB VRAM capacity together with 936 GB/s bandwidth. Its 35.6 TFLOPS FP32 rating and 142 TFLOPS FP16 rating with sparsity accelerate large batch inference compared with lower figures on the alternative card.
When to Choose the RTX A2000
The RTX A2000 fits inference or fine tuning tasks where the 70 W TDP limit must be observed and where 12 GB VRAM proves sufficient. Its PCIe form factor and lower power draw allow deployment in dense workstation configurations that cannot accommodate the 350 W requirement of the RTX 3090.
Use Cases
The RTX 3090 supplies 24 GB VRAM and 35.6 TFLOPS FP32 performance that exceed the 12 GB and 8 TFLOPS limits of the RTX A2000.
FP16 throughput with sparsity of 142 TFLOPS on the RTX 3090 surpasses the 63.9 TFLOPS rating on the RTX A2000 while 936 GB/s bandwidth supports larger concurrent batches.
Both cards share Ampere architecture and PCIe interconnect so either handles moderate fine tuning when VRAM fits within 12 GB on the RTX A2000 or 24 GB on the RTX 3090.
The 24 GB memory capacity and 936 GB/s bandwidth of the RTX 3090 accommodate higher resolution image generation workloads beyond the 12 GB ceiling of the RTX A2000.
FP32 performance of 35.6 TFLOPS combined with 936 GB/s bandwidth on the RTX 3090 accelerates double precision scientific kernels relative to the 8 TFLOPS and 288 GB/s on the RTX A2000.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3090 and the RTX A2000. 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.
