Performance Analysis
The RTX 4090 delivers 165.2 TFLOPS dense FP16 performance against its own 82.6 TFLOPS FP32 performance. The TITAN Xp publishes no FP16 figure so no direct dense FP16 comparison applies. Memory bandwidth on the RTX 4090 reaches 1008 GB/s which is 1.84 times the 548 GB/s on the TITAN Xp. This bandwidth difference supports larger batch sizes during training and inference on the RTX 4090. The RTX 4090 also lists 330.3 TFLOPS dense FP8 performance while the TITAN Xp lists no FP8 figure.

When to Choose the RTX 4090
The RTX 4090 suits workloads that require 24 GB VRAM and 165.2 TFLOPS dense FP16 throughput. Its 1008 GB/s bandwidth enables larger batch processing than the 548 GB/s available on the alternative. The 82.6 TFLOPS FP32 rating further supports intensive scientific and AI computations.
When to Choose the TITAN Xp
The TITAN Xp suits workloads constrained to 250W TDP where the 12.1 TFLOPS FP32 rating remains sufficient. Its PCIe 3.0 interconnect matches older system requirements that may not accommodate the RTX 4090 PCIe 4.0 interface.
Use Cases
The RTX 4090 supplies 24 GB VRAM and 165.2 TFLOPS dense FP16 which exceed the TITAN Xp specifications.
The RTX 4090 supplies 1008 GB/s bandwidth and 330.3 TFLOPS dense FP8 which support higher throughput than the TITAN Xp.
