Performance Analysis
The RTX 4080 SUPER delivers 48.7 TFLOPS FP16 while the RTX 5090 delivers 209.5 TFLOPS dense FP16 so the latter processes matrix operations more than four times faster under dense conditions. FP32 throughput follows the same pattern at 48.7 TFLOPS versus 104.8 TFLOPS allowing the RTX 5090 to complete floating point workloads in roughly half the time when both figures are treated as dense. Memory bandwidth of 1792 GB/s on the RTX 5090 versus 717 GB/s on the RTX 4080 SUPER supports larger batch sizes during training or inference without swapping data to host memory as frequently.

When to Choose the RTX 4080 SUPER
The RTX 4080 SUPER variant suits deployments where power draw must stay at 320 W and 16 GB GDDR6X memory meets workload requirements. Its lower TDP reduces cooling demands in dense server racks compared with the 575 W TDP of the RTX 5090 variant.
When to Choose the RTX 5090
The RTX 5090 variant suits workloads that require 32 GB GDDR7 memory and 1792 GB/s bandwidth to handle large models or high resolution data sets. Its 104.8 TFLOPS FP32 and 209.5 TFLOPS dense FP16 figures accelerate both training and inference relative to the 48.7 TFLOPS figures on the RTX 4080 SUPER variant.
Use Cases
The RTX 5090 variant supplies 32 GB GDDR7 memory and 104.8 TFLOPS FP32 compared with 16 GB and 48.7 TFLOPS on the RTX 4080 SUPER variant.
The RTX 5090 variant supplies 209.5 TFLOPS dense FP16 and 1792 GB/s bandwidth allowing larger batch sizes than the 48.7 TFLOPS and 717 GB/s figures of the RTX 4080 SUPER variant.
The RTX 5090 variant supplies 32 GB memory capacity that accommodates larger fine tuning data sets than the 16 GB capacity of the RTX 4080 SUPER variant.
Both variants handle image generation workloads yet the RTX 5090 variant completes iterations faster due to higher dense FP16 throughput while the RTX 4080 SUPER variant remains viable at lower power.
The RTX 5090 variant supplies 104.8 TFLOPS FP32 and 1792 GB/s bandwidth that accelerate large matrix calculations beyond the 48.7 TFLOPS and 717 GB/s figures of the RTX 4080 SUPER variant.
Frequently Asked Questions
What are the TDP ratings of the two variants?▾
