Performance Analysis

The RTX 5080's FP16 and FP32 performance surges to 56.3 TFLOPS from the GTX 1080's 8.9 TFLOPS, enabling six times faster matrix operations central to model training and inference. This delta accelerates gradient computations in training by processing more samples per second and reduces latency in inference for real-time applications. Equal FP16 and FP32 rates on both GPUs support mixed-precision workflows without penalties.

Memory bandwidth triples to 960 GB/s on the RTX 5080 versus 320 GB/s on the GTX 1080, sustaining larger batch sizes in memory-bound tasks like transformer training. The RTX 5080's 16 GB GDDR7 VRAM exceeds the GTX 1080's 8 to 11 GB GDDR5X, accommodating bigger models or datasets without swapping to host RAM, which cuts throughput. Higher TDP of 360W on the RTX 5080 versus 180W reflects this capability, demanding robust cooling.

In practice, these specs position the RTX 5080 for modern large language models, where the GTX 1080 bottlenecks on bandwidth and capacity during batch sizes over 16.

When to Choose the GTX 1080

The GTX 1080 fits low-power environments capped at 180W TDP, such as edge servers or laptops where 360W exceeds limits. Its 8.9 TFLOPS suffices for lightweight inference on models under 8 GB, and pricing from $0.30 per hour across two offers keeps costs minimal for non-intensive tasks. Legacy Pascal-optimized software runs natively without recompilation.

When to Choose the RTX 5080

The RTX 5080 excels in demanding AI pipelines requiring 56.3 TFLOPS for rapid training iterations or high-concurrency inference. Its 960 GB/s bandwidth and 16 GB VRAM handle batch sizes up to 128 in large models, far beyond the GTX 1080's 320 GB/s and 11 GB maximum. At $0.25 per hour average $0.38, it delivers superior performance per dollar across four offers.
