Performance Analysis
The RTX A5000 FP32 figure of 27.8 TFLOPS exceeds the GTX 1080 dense FP32 figure of 8.9 TFLOPS by a factor of roughly three times which translates to faster completion of dense matrix operations in training and inference pipelines. The RTX A5000 also lists 222.2 TFLOPS FP16 with sparsity that has no counterpart published for the GTX 1080 so direct dense FP16 ratios cannot be formed. Memory bandwidth of 768 GB/s on the RTX A5000 versus 320 GB/s on the GTX 1080 permits larger batch sizes before memory capacity of 24 GB versus 8 to 11 GB becomes the limiting factor during data movement in scientific computing kernels.

When to Choose the GTX 1080
The GTX 1080 suits workloads that fit within 8 to 11 GB VRAM and operate primarily on dense FP32 at 8.9 TFLOPS where the 180W TDP reduces power draw compared with 230W. Scenarios such as legacy application testing or light inference tasks that do not require NVLink or PCIe 4.0 benefit from retaining the older card.
When to Choose the RTX A5000
The RTX A5000 fits tasks that demand 24 GB VRAM together with 768 GB/s bandwidth and 222.2 TFLOPS FP16 with sparsity for accelerated sparse tensor operations. Users running fine tuning or stable diffusion workloads gain from the higher 27.8 TFLOPS dense FP32 and the availability of NVLink interconnects.
Use Cases
The RTX A5000 supplies 24 GB VRAM and 27.8 TFLOPS dense FP32 that exceed the GTX 1080 limits of 8 to 11 GB and 8.9 TFLOPS.
The RTX A5000 222.2 TFLOPS FP16 with sparsity and 768 GB/s bandwidth support larger models than the GTX 1080 320 GB/s bandwidth allows.
The RTX A5000 24 GB capacity and NVLink interconnect handle parameter updates more effectively than the GTX 1080 PCIe 3.0 connection.
The RTX A5000 768 GB/s memory bandwidth paired with 27.8 TFLOPS dense FP32 accelerates image generation beyond GTX 1080 capabilities.
The GTX 1080 8.9 TFLOPS dense FP32 at 180W TDP suffices for smaller grids while the RTX A5000 27.8 TFLOPS dense FP32 suits larger simulations.
