The NVIDIA RTX 3080 Ti, with its 12GB of GDDR6X VRAM and Ampere architecture, is exceptionally well-suited for running the CLIP ViT-L/14 model. CLIP ViT-L/14, being a relatively small vision model with only 0.4 billion parameters and requiring just 1.5GB of VRAM in FP16 precision, leaves a significant 10.5GB VRAM headroom on the RTX 3080 Ti. This ample headroom ensures that the model can be loaded and executed without any memory constraints, even when dealing with larger batch sizes or more complex image processing pipelines.
Furthermore, the RTX 3080 Ti's substantial memory bandwidth of 0.91 TB/s ensures rapid data transfer between the GPU and its memory, which is crucial for maintaining high throughput during inference. The presence of 10240 CUDA cores and 320 Tensor Cores accelerates the matrix multiplications and other tensor operations that are fundamental to deep learning models like CLIP. This combination of high VRAM, high memory bandwidth, and abundant compute resources translates into excellent performance for CLIP ViT-L/14 on the RTX 3080 Ti.
Given the hardware capabilities, users can expect excellent performance from the RTX 3080 Ti when running CLIP ViT-L/14. We estimate the throughput to be around 90 tokens per second, making real-time or near-real-time applications feasible. Additionally, a batch size of 32 can be comfortably accommodated, further increasing the overall efficiency of the inference process.
For optimal performance, leverage TensorRT for inference acceleration, as it can significantly reduce latency and increase throughput by optimizing the model for the specific RTX 3080 Ti architecture. Start with FP16 precision for the best balance between speed and accuracy. If further optimization is needed, consider quantization techniques like INT8, but be aware that this might slightly impact the model's accuracy. Experiment with different batch sizes to find the sweet spot that maximizes GPU utilization without exceeding VRAM limits or introducing excessive latency.
Also, ensure that you are using the latest NVIDIA drivers and CUDA toolkit to take full advantage of the RTX 3080 Ti's capabilities. Monitor GPU utilization and memory consumption during inference to identify potential bottlenecks and adjust settings accordingly. If you are running other GPU-intensive tasks concurrently, consider allocating dedicated resources to the CLIP inference process to avoid performance degradation.
