NVIDIA GeForce RTX 3090 for fine-tuning — is it fast enough?
💡 Answer
Compute specs on NVIDIA GeForce RTX 3090: 142 FP16 TFLOPS, 35.6 FP32 TFLOPS, with 936 GB/s of memory bandwidth on a 24 GB Ampere package.
In practice, that's enough horsepower to handle large-batch FP16 pre-training with near-peak utilisation and to sustain production inference on large language models under typical batch-serving patterns. Performance-per-dollar is competitive at $0.12 per hour cloud pricing, especially for teams that can push batch sizes to fully saturate tensor cores.
