Quadro P4000 vs RTX 3090 Ti

The RTX 3090 Ti outperforms the Quadro P4000 by 6.7 times in FP32 and FP16 compute at 35.6 TFLOPS versus 5.3 TFLOPS, accelerating deep learning training and inference significantly. Equal FP16 to FP32 ratios on both GPUs indicate balanced half-precision support, but the RTX 3090 Ti handles modern mixed-precision workflows far better due to its Ampere tensor cores. Memory bandwidth of 936 GB/s on the RTX 3090 Ti versus 243 GB/s on the P4000 allows 3.85 times larger batch sizes in training, reducing overhead and improving throughput for models exceeding 8 GB VRAM. The 24 GB capacity supports complex LLMs, while the P4000 limits to smaller models or lower resolutions. NVLink interconnect on the RTX 3090 Ti enables multi-GPU scaling unavailable on the P4000, vital for distributed training.

The Quadro P4000 suits legacy professional applications optimized for Pascal, such as older CAD software or certified drivers requiring Quadro stability. Its 105W TDP fits power-constrained cloud instances or edge deployments where 350W exceeds limits. At $0.51 per hour average, it provides cost-effective access for light visualization tasks not demanding over 8 GB VRAM or 5.3 TFLOPS.

The RTX 3090 Ti dominates AI and rendering workloads needing 24 GB VRAM for large models or high-resolution textures. Its 35.6 TFLOPS and 936 GB/s bandwidth excel in training and inference at $0.25 per hour average, offering superior performance per dollar. NVLink supports multi-GPU setups for scaled compute.
