Performance Analysis
The FP32 performance ratio reaches 56.3 TFLOPS to 8.9 TFLOPS when the RTX 5080 is measured against the GTX 1080. Memory bandwidth at 960 GB/s versus 320 GB/s permits larger batch sizes during workloads that move substantial data volumes. The RTX 5080 lists dense FP16 at 112.6 TFLOPS and FP16 with sparsity at 225.1 TFLOPS while the GTX 1080 does not publish an FP16 figure so no direct dense FP16 comparison applies. Training and inference tasks on the RTX 5080 therefore operate with dense FP16 at 112.6 TFLOPS or FP16 with sparsity at 225.1 TFLOPS depending on workload sparsity patterns.

When to Choose the GTX 1080
The GTX 1080 suits scenarios that require only 8.9 TFLOPS FP32 and operate within a 180W TDP limit. Its 320 GB/s bandwidth remains adequate for lighter inference tasks that do not demand the 16 GB VRAM capacity of newer cards.
When to Choose the RTX 5080
Its 16 GB VRAM supports larger models where the GTX 1080 8 to 11 GB capacity proves insufficient.
Use Cases
The RTX 5080 supplies dense FP16 at 112.6 TFLOPS and 16 GB VRAM whereas the GTX 1080 does not publish FP16 and carries only 8 to 11 GB.
The RTX 5080 provides 56.3 TFLOPS FP32 and 960 GB/s bandwidth that exceed the GTX 1080 values of 8.9 TFLOPS and 320 GB/s.
The RTX 5080 lists dense FP16 at 112.6 TFLOPS and FP16 with sparsity at 225.1 TFLOPS that allow efficient parameter updates beyond GTX 1080 capability.
The RTX 5080 memory bandwidth of 960 GB/s and 16 GB VRAM support higher resolution generation compared with the GTX 1080 320 GB/s and 8 to 11 GB.
The GTX 1080 at 180W TDP handles basic FP32 workloads at 8.9 TFLOPS while the RTX 5080 at 360W TDP handles the same tasks at 56.3 TFLOPS when higher throughput is required.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the GTX 1080 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.
