When to Choose the RTX 4080
The RTX 4080 suits environments that prioritize lower power draw at 320W TDP and PCIe 4.0 interconnect when FP16 dense throughput of 97.5 TFLOPS meets application needs. Its 717 GB/s memory bandwidth remains adequate for inference tasks that do not require the higher 960 GB/s available on the RTX 5080.
When to Choose the RTX 5080
Its PCIe 5.0 interconnect and 360W TDP support sustained operation in systems that can accommodate the additional power and newer interface.
Use Cases
The RTX 5080 provides 112.6 TFLOPS FP16 dense and 960 GB/s bandwidth which exceed the 97.5 TFLOPS and 717 GB/s of the RTX 4080 for larger batch processing.
FP16 dense performance of 112.6 TFLOPS on the RTX 5080 surpasses 97.5 TFLOPS on the RTX 4080 while 960 GB/s bandwidth supports higher throughput.
The RTX 5080 delivers 56.3 TFLOPS FP32 and 450.2 TOPS INT8 dense compared with 48.7 TFLOPS and 389.9 TOPS on the RTX 4080 for faster adaptation steps.
Both GPUs supply 16 GB VRAM and the FP16 dense ratings of 97.5 TFLOPS versus 112.6 TFLOPS produce comparable image generation speeds under typical workloads.
FP32 throughput of 56.3 TFLOPS and memory bandwidth of 960 GB/s on the RTX 5080 exceed the 48.7 TFLOPS and 717 GB/s figures of the RTX 4080.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 4080 and the RTX 5080. 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.
