Quadro P5000 vs RTX 3080 Ti

The RTX 3080 Ti dominates in raw compute with 29.8 TFLOPS for FP16 and FP32, compared to the Quadro P5000's 8.9 TFLOPS: this enables training times up to 3.3 times faster for models relying on half-precision or single-precision arithmetic. Inference workloads similarly benefit, as higher throughput reduces latency in deployment scenarios.

Memory bandwidth presents a clear advantage for the RTX 3080 Ti at 760 GB/s over the P5000's 288 GB/s: larger batch sizes become feasible during training, which sustains higher GPU utilization and accelerates convergence without memory bottlenecks. The P5000's 16 GB VRAM supports bigger models than the 12 GB on the RTX 3080 Ti, though slower access limits effective use in bandwidth-hungry tasks.

Power draw differs significantly, with the RTX 3080 Ti at 320W versus 180W for the P5000, impacting cloud instance costs in prolonged runs but favoring the newer card's efficiency per flop.

The Quadro P5000 suits workloads demanding over 12 GB VRAM, such as processing massive datasets or models that exceed the RTX 3080 Ti's capacity with its 16 GB GDDR5X. Professional software certified for Quadro drivers, like certain CAD or legacy simulation tools, performs reliably on this GPU.

Lower TDP of 180W makes it preferable in power-constrained cloud environments where 320W instances prove unavailable.

The RTX 3080 Ti excels in performance-critical AI tasks, leveraging 29.8 TFLOPS FP16/FP32 and 760 GB/s bandwidth for rapid training and inference at $0.14 per hour average. Modern frameworks optimized for Ampere architecture yield optimal results on this GPU.

Cost savings become evident in extended jobs, as its speed completes work in one-third the time of the P5000, offsetting the older card's $0.78 hourly rate.
