Decoding AI Performance on NVIDIA RTX PCs
The era of AI PCs powered by NVIDIA RTX and GeForce RTX technologies has arrived, presenting a new way to assess performance for AI-accelerated tasks. These metrics can be complex to navigate when determining the best choice between desktops and laptops.
Coming Out on TOPS
TOPS, which stands for trillions of operations per second, serves as a baseline metric analogous to a car engine’s horsepower rating. Higher numbers indicate superior performance levels, such as the GeForce RTX 4090 GPU offering over 1,300 TOPS, essential for demanding AI tasks like generative content creation and processing large language models.
Insert Tokens to Play
AI performance evaluates the number of tokens generated by a model, where tokens can represent words, punctuation, or spaces. The speed of AI performance is measured in “tokens per second,” while batch size, the quantity of inputs processed simultaneously, also plays a crucial role.
- RTX GPUs boast up to 24GB of high-speed VRAM for GeForce RTX GPUs and up to 48GB for NVIDIA RTX GPUs, facilitating larger batch sizes and models.
- Tensor Cores and TensorRT-LLM software significantly accelerate operations for deep learning and generative AI models.
Text-to-Image, Faster Than Ever
Image generation speed is another significant performance indicator, particularly when using models like Stable Diffusion to convert text descriptions into visual representations. RTX GPUs offer quicker results compared to CPUs or NPUs and further boost performance with TensorRT extensions.
- TensorRT acceleration enhances the generation of images from prompts, making it up to 2x faster using the SDXL Base checkpoint.
- Recent additions like TensorRT acceleration for ComfyUI in Stable Diffusion lead to 60% faster image generation and 70% faster video conversion.
The Results Are in and Open Sourced
AI researchers at Jan.ai integrated TensorRT-LLM into their local chatbot app, discovering a notable speed improvement compared to other processing methods. Sharing their methodology openly allows others to evaluate generative AI performance effectively in various applications.
From gaming to generative AI, vital metrics include TOPS, images per second, tokens per second, and batch size, all contributing to the overall performance assessment in AI-driven tasks.
