Performance Analysis
The RTX 3090 Ti variant reports 35.6 TFLOPS dense FP16 and 35.6 TFLOPS dense FP32. The RTX A6000 variant reports 38.7 TFLOPS dense FP16 and 38.7 TFLOPS dense FP32. The 3.1 TFLOPS dense FP16 advantage on the RTX A6000 variant supports modestly higher throughput during training or inference when batch sizes remain identical. Memory bandwidth of 936 GB per second on the RTX 3090 Ti variant permits larger batches than the 768 GB per second on the RTX A6000 variant when model size fits in 24 GB. The 50 W higher TDP on the RTX 3090 Ti variant requires additional cooling capacity compared with the 300 W TDP on the RTX A6000 variant.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3090 Ti and the RTX A6000. 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.
