Performance Analysis

FP16 performance defines a key advantage for the L4: 121 TFLOPS enables faster half-precision training and inference for large language models compared to the RTX 3090 Ti's 35.6 TFLOPS. The L4's exclusive FP8 capability at 242 TFLOPS accelerates quantized inference, reducing model size and latency in deployment scenarios. In FP32 workloads, the RTX 3090 Ti holds a slight lead at 35.6 TFLOPS over the L4's 30.3 TFLOPS, benefiting scientific simulations or graphics rendering. Memory bandwidth impacts batch sizes directly: the RTX 3090 Ti's 936 GB/s supports larger batches in training Stable Diffusion or LLMs, minimizing data transfer bottlenecks, whereas the L4's 300 GB/s suits smaller, efficient batches. Power efficiency tilts toward the L4 with 72W TDP, enabling up to four times more GPUs per server rack than the 350W RTX 3090 Ti, crucial for scalable cloud inference. Interconnect options differ as well: PCIe 4.0 on the L4 versus NVLink on the RTX 3090 Ti, with NVLink aiding multi-GPU training setups.
