Performance Analysis
Dense FP16 performance equals 71 TFLOPS on the RTX 3090 compared with 364 TFLOPS on the RTX 6000 Ada while sparse FP16 performance equals 142 TFLOPS on the RTX 3090 compared with 728 TFLOPS on the RTX 6000 Ada. The FP16 to FP32 ratio supports mixed precision training and inference where the RTX 6000 Ada delivers higher throughput per watt given its 300W TDP. Memory bandwidth of 936 GB/s on the RTX 3090 versus 960 GB/s on the RTX 6000 Ada influences sustainable batch sizes yet the 48 GB VRAM capacity on the RTX 6000 Ada permits substantially larger batches than the 24 GB capacity on the RTX 3090.

When to Choose the RTX 3090
The RTX 3090 suits workloads that require NVLink interconnect for multi GPU scaling. Its 24 GB VRAM capacity remains adequate for models that fit within that limit while its 350W TDP aligns with systems already provisioned for higher power draw.
When to Choose the RTX 6000 Ada
The RTX 6000 Ada suits workloads that require 48 GB VRAM capacity for larger models. Its dense FP16 rating of 364 TFLOPS and FP32 rating of 91.1 TFLOPS deliver higher throughput than the RTX 3090 while its 300W TDP reduces power demand.
