When to Choose the RTX 4070 Ti
The RTX 4070 Ti variant with 12 GB GDDR6X suits inference tasks that fit within its memory capacity and operate at the 200W TDP. Workloads that require only 29.1 TFLOPS FP32 benefit from its lower power draw without needing the 450W TDP of the alternative.
When to Choose the RTX 4090
The RTX 4090 variant with 24 GB GDDR6X handles training and inference that demand the 165.2 TFLOPS dense FP16 and 1008 GB/s bandwidth. Models exceeding 12 GB memory capacity run directly on this variant at the 450W TDP.
Use Cases
The RTX 4090 variant supplies 24 GB memory and 82.6 TFLOPS FP32 to support larger models.
The RTX 4090 variant provides 165.2 TFLOPS dense FP16 and 1008 GB/s bandwidth for higher throughput.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 4070 Ti and the RTX 4090. 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.
