  2. First Token Latency (FTL): This is the time it takes for the system to produce the first token in the sequence. For the comparison, the FTL is 5,000 milliseconds (5 seconds). This latency is typically higher due to the initial processing required to start generating text.

  3. Input Sequence Length: This refers to the length of the input data sequence fed into the model. Here, the input sequence length is 32,768 tokens.

  4. Output Sequence Length: This is the length of the sequence that the model generates as output. In this case, the output sequence length is 1,028 tokens.

  5. 8x Eight-Way DGX H100 GPUs Air-Cooled vs. 1x Eight-Way DGX B200 Air-Cooled: This compares the performance of a setup with eight DGX H100 systems, each configured with eight GPUs, against a single DGX B200 system configured with eight GPUs. Both setups are air-cooled.

Speed - Context and Comparison

Token-to-Token Latency (TTL)

  • 50ms TTL: This indicates that once the initial token is generated, each subsequent token can be generated every 50 milliseconds.

    • Context:

      • Human Conversation Speed: In human conversation, a typical response time is around 200 milliseconds. Thus, a 50ms TTL is significantly faster, enabling highly responsive interactions that feel instantaneous to users.

      • Typing Speed: A proficient typist averages around 60 words per minute, translating to roughly one word per second. With a 50ms TTL, the system can generate up to 20 tokens per second, outpacing human typing speed and supporting applications like real-time transcription and live chatbots.

      • Gaming and Interactive Media: In fast-paced online gaming, latency of 100ms or less is considered excellent for seamless interaction. A 50ms TTL ensures AI-driven game elements (like NPC responses or dynamic content generation) can keep up with real-time player actions.

First Token Latency (FTL)

  • 5,000ms FTL: This shows the initial delay before the system starts producing tokens, which is relatively high but typical for large-scale models due to the extensive computations involved in processing the initial input.

    • Context:

      • Complex Model Initialization: Large language models, like those used in natural language processing and understanding, require significant computation to process the initial input and generate the first token. An FTL of 5,000ms reflects the complexity and depth of these models.

      • Batch Processing in AI: In many AI applications, initial latency can be mitigated by processing data in batches. For instance, in customer service automation, the system can preprocess common queries during off-peak times, reducing perceived latency for users.

      • Video Streaming and Buffering: Similar to buffering in video streaming, the initial load time (FTL) ensures smooth performance during the interaction. Once the first token is produced, the subsequent tokens follow rapidly, akin to continuous streaming without interruptions.

Summary

  • Real-Time Applications: A TTL of 50ms is impressively fast and suitable for real-time applications where responsiveness is critical, such as virtual assistants, live customer support, and interactive gaming.

  • Initial Processing Delay: While a 5,000ms FTL may seem lengthy, it is a trade-off for the high complexity and capability of large-scale AI models, and strategies like batch processing can help mitigate its impact on user experience.

Overall, these performance metrics highlight the advanced capabilities of the NVIDIA DGX B200 system, making it highly effective for demanding AI applications that require both high-speed processing and the ability to handle complex, large-scale models.
