Performance Analysis
Dense FP16 performance measures 130.5 TFLOPS on the Quadro RTX 8000 compared to 71 TFLOPS dense FP16 on the RTX 3090. This delta indicates the Quadro RTX 8000 can handle higher throughput in dense tensor operations for training workloads. FP32 figures of 16.3 TFLOPS on the Quadro RTX 8000 and 35.6 TFLOPS on the RTX 3090 show the RTX 3090 delivers more than double the dense FP32 rate. Memory bandwidth of 672 GB/s on the Quadro RTX 8000 versus 936 GB/s on the RTX 3090 affects how quickly data moves during large batch processing. The lower TDP of 260W on the Quadro RTX 8000 supports sustained operation with reduced power draw relative to the 350W TDP on the RTX 3090.

When to Choose the Quadro RTX 8000
The Quadro RTX 8000 suits workloads that require 48 GB VRAM for holding large models or datasets in memory. Its 130.5 TFLOPS dense FP16 rating supports dense tensor computations where higher VRAM capacity outweighs the 35.6 TFLOPS FP32 advantage of the alternative. The 260W TDP enables deployment in power constrained environments.
When to Choose the RTX 3090
The 350W TDP aligns with systems prepared for higher power delivery.
Use Cases
The Quadro RTX 8000 provides 48 GB VRAM which supports larger model sizes than the 24 GB on the RTX 3090.
The RTX 3090 achieves 35.6 TFLOPS FP32 which exceeds the 16.3 TFLOPS FP32 on the Quadro RTX 8000 for faster token generation.
The Quadro RTX 8000 supplies 48 GB VRAM to accommodate full precision fine tuning of models that exceed 24 GB limits.
The RTX 3090 delivers 936 GB/s bandwidth which moves data faster than the 672 GB/s on the Quadro RTX 8000 during image generation.
