What actually differs
Both GPUs launched in 2020: the GeForce RTX 3060 Ti on Ampere and the GeForce RTX 3090 on Ampere.
Dense throughput for the GeForce RTX 3060 Ti against the GeForce RTX 3090: FP64 0.3 vs 0.6 TFLOPS, FP32 16 vs 36 TFLOPS, FP16 32 vs 71 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 8 GB against 24 GB. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.
Power budgets are 200 W for the GeForce RTX 3060 Ti and 350 W for the GeForce RTX 3090. At FP32 that works out to 0.08 against 0.10 TFLOPS per watt.
For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
