Performance Analysis
The FP32 figures of 8.9 TFLOPS on the GTX 1080 and 19.2 TFLOPS on the RTX A4000 represent dense performance in both cases and indicate that the RTX A4000 supplies more than double the dense FP32 throughput. This delta affects training and inference by allowing larger models or faster iteration on the RTX A4000 when dense FP32 operations dominate. Memory bandwidth of 320 GB per s on the GTX 1080 versus 448 GB per s on the RTX A4000 influences batch sizes because higher bandwidth supports larger data transfers per cycle without increasing VRAM capacity alone. The RTX A4000 also lists 153.4 TFLOPS FP16 with sparsity while the GTX 1080 lists no FP16 value so comparisons remain limited to dense FP32 figures only.

When to Choose the GTX 1080
The GTX 1080 fits scenarios that require only 8.9 TFLOPS dense FP32 and operate within PCIe 3.0 slots where the 180 W TDP remains acceptable. Workloads that stay below 8 to 11 GB VRAM and do not require the 448 GB per s bandwidth of newer cards can use the GTX 1080 without performance loss relative to its specifications.
When to Choose the RTX A4000
Workloads that run on PCIe 4.0 interconnects and stay within the 140 W TDP envelope gain from these higher specification values.
Use Cases
The RTX A4000 supplies 19.2 TFLOPS dense FP32 and 16 to 20 GB VRAM which exceed the GTX 1080 values of 8.9 TFLOPS and 8 to 11 GB.
The RTX A4000 supplies 153.4 TFLOPS FP16 with sparsity and 448 GB per s bandwidth which exceed GTX 1080 specifications.
The RTX A4000 supplies 19.2 TFLOPS dense FP32 with 140 W TDP allowing larger batches than the GTX 1080 8.9 TFLOPS and 180 W TDP.
The RTX A4000 supplies 16 to 20 GB VRAM and 448 GB per s bandwidth which support higher resolution outputs than the GTX 1080 limits.
Both GPUs provide published dense FP32 figures so either meets basic FP32 requirements when VRAM fits within 8 to 11 GB.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the GTX 1080 and the RTX A4000. 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.
