Performance Analysis
Dense FP16 throughput reaches 40.3 TFLOPS on the RTX 2080 Ti and 71 TFLOPS on the RTX 3090 Ti while FP32 throughput stands at 10 TFLOPS versus 35.6 TFLOPS. The higher dense FP16 number on the RTX 3090 Ti supports larger batch sizes during training and faster token generation during inference when both GPUs run dense operations. Memory bandwidth of 448 GB/s on the RTX 2080 Ti versus 936 GB/s on the RTX 3090 Ti limits the maximum batch size for large models on the older card even though both share the same dense INT8 rating within their respective families.

When to Choose the RTX 2080 Ti
The RTX 2080 Ti variant suits workloads that fit inside 11 GB GDDR6 and operate under a 215W TDP limit. Its PCIe 3.0 interconnect remains compatible with older server platforms that do not require the 936 GB/s bandwidth of the RTX 3090 Ti.
When to Choose the RTX 3090 Ti
Its 936 GB/s bandwidth and PCIe 4.0 interconnect enable larger batch sizes than the 448 GB/s and PCIe 3.0 of the RTX 2080 Ti.
Use Cases
The RTX 3090 Ti variant supplies 24 GB GDDR6X that accommodates models too large for the 11 GB GDDR6 on the RTX 2080 Ti variant.
Dense FP16 at 71 TFLOPS on the RTX 3090 Ti variant exceeds the 40.3 TFLOPS dense FP16 on the RTX 2080 Ti variant and supports higher throughput.
The 936 GB/s bandwidth of the RTX 3090 Ti variant permits larger batch sizes than the 448 GB/s bandwidth of the RTX 2080 Ti variant.
24 GB GDDR6X on the RTX 3090 Ti variant holds larger diffusion models that exceed the 11 GB limit of the RTX 2080 Ti variant.
Both variants share NVLink interconnect and the RTX 2080 Ti variant at 215W TDP meets power-constrained scientific workloads that fit in 11 GB.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 2080 Ti and the RTX 3090 Ti. 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.
