Performance Analysis
Dense FP16 performance measures 40.3 TFLOPS on the RTX 2080 Ti against 165.2 TFLOPS on the RTX 4090. Dense FP32 performance measures 10 TFLOPS on the RTX 2080 Ti against 82.6 TFLOPS on the RTX 4090. The higher dense FP16 figure on the RTX 4090 supports larger batch sizes during training workloads compared with the RTX 2080 Ti. Memory bandwidth of 1008 GB/s on the RTX 4090 family exceeds the 448 GB/s on the RTX 2080 Ti family and therefore permits greater data throughput per second. Dense INT8 performance reaches 161.1 TOPS on the RTX 2080 Ti family and 660.6 TOPS on the RTX 4090 family. These differences translate to faster inference throughput on the RTX 4090 when sparsity remains unused.

When to Choose the RTX 2080 Ti
The RTX 2080 Ti variant suits workloads that fit within 11 GB GDDR6 and require NVLink connectivity. Lower TDP of 215W on the RTX 2080 Ti family reduces power draw in constrained environments. Dense FP32 at 10 TFLOPS remains adequate for smaller scientific computing tasks that do not demand the 82.6 TFLOPS available on the RTX 4090.
When to Choose the RTX 4090
The RTX 4090 variant suits workloads that require 24 GB GDDR6X for larger models. PCIe 4.0 interconnect on the RTX 4090 provides higher bandwidth than PCIe 3.0 on the RTX 2080 Ti. Dense FP16 at 165.2 TFLOPS on the RTX 4090 accelerates fine tuning compared with 40.3 TFLOPS on the RTX 2080 Ti.
Use Cases
The RTX 4090 provides 24 GB GDDR6X and dense FP16 at 165.2 TFLOPS while the RTX 2080 Ti offers only 11 GB GDDR6 and 40.3 TFLOPS.
The RTX 4090 delivers dense INT8 at 660.6 TOPS and 1008 GB/s bandwidth compared with 161.1 TOPS and 448 GB/s on the RTX 2080 Ti.
The RTX 4090 supports larger batch sizes with 24 GB GDDR6X and dense FP16 at 165.2 TFLOPS versus the RTX 2080 Ti limits.
The RTX 4090 handles higher resolution images with 24 GB GDDR6X while the RTX 2080 Ti is restricted to 11 GB GDDR6.
