TOPS of the Class: Harnessing AI Performance on RTX PCs and Workstations

As we navigate the fascinating realm of artificial intelligence, the era of AI PCs has taken a significant leap forward, driven by NVIDIA RTX technology. This evolution has radically transformed how we assess performance for AI-accelerated tasks, introducing a new language that may seem daunting but is essential for understanding the capabilities of modern desktops and laptops.

Understanding the Metrics: TOPS and Beyond

In the world of gaming, metrics like frames per second (FPS) are standard. However, the evaluation of AI performance introduces different benchmarks, notably TOPS, or trillions of operations per second. This metric serves as a raw performance indicator—the higher the TOPS, the better the engine driving your tasks. For instance, the recently unveiled Copilot+ PC lineup by Microsoft boasts neural processing units capable of achieving upwards of 40 TOPS, just enough for lighter AI functions, such as organizing daily notes using a chatbot.

On the other end of the spectrum, NVIDIA’s offerings, like the GeForce RTX 4090, deliver an astounding 1,300 TOPS. This remarkable processing power allows for intensive tasks such as AI-driven content creation, super-resolution in gaming, and image generation from textual prompts.

Evaluating performance metrics in AI technology

The Role of Tokens and Batch Size

Yet, TOPS is merely one piece of the puzzle. Performance in large language models (LLMs) is also quantified by the number of tokens produced—these can be whole words, fragments, or even punctuation. The output metric, referred to as tokens per second, is crucial for understanding how LLMs function.

Batch size comes into play as another vital aspect—this refers to the number of inputs processed concurrently during a single inference pass. Higher batch sizes can enhance efficiency for concurrent processing but necessitate increased memory capacity, an area where RTX GPUs shine. Equipped with up to 24GB for GeForce RTX and 48GB for NVIDIA RTX, these GPUs are perfect for handling vast models, supporting larger batch sizes, and facilitating rapid throughput. The combination of dedicated Tensor Cores and TensorRT-LLM software optimally boosts generative AI tasks, leveraging the more than 100 million Windows PCs powered by RTX GPUs.

Accelerating Image Generation

Speed is another crucial metric when assessing image generation capabilities, with models like Stable Diffusion leading the charge in text-to-image conversion. The integration of RTX GPUs allows for lightning-fast conversions, outperforming standard CPU or NPU processing speeds. Using frameworks like the Automatic1111 interface with TensorRT, users can achieve image generation up to twice as fast than without these optimizations.

Additionally, the introduction of ComfyUI has further enhanced workflows, allowing users to create images from text prompts with TensorRT acceleration, significantly cutting down on processing times compared to older hardware setups.

Real-World Testing with Jan.ai

In a practical application, the team at Jan.ai recently integrated TensorRT-LLM into their local chatbot application to evaluate these advancements firsthand. Their results indicate that TensorRT is 30-70% faster than its counterpart, llama.cpp, creating a substantial difference in efficiency across various tasks. This invitation for community benchmarking serves as a vital resource for anyone looking to enhance their understanding of generative AI performance.

As we adjust to the rapid evolution of AI technology, it becomes increasingly clear—speed is essential. Whether it’s TOPS, tokens per second, batch size, or speed of image generation, these metrics are critical in determining which systems excel in high-performance AI tasks. The intersection of gaming, generative AI, and videoconferencing optimally showcases how far we’ve come while hinting at what’s next.
