+### Colossal-AI Benchmark
+
+To see how these performance gains translate to real-world applications, we conducted a large language model training benchmark using Colossal-AI on Llama-like models. The tests were run on both 8-card and 16-card configurations for 7B and 70B models, respectively.

+The results from the Colossal-AI benchmark provide the most practical insight. For the 7B model on 8 cards, the **B200 achieved a 50% higher throughput** and a significant increase in TFLOPS per GPU. For the 70B model on 16 cards, the B200 again demonstrated a clear advantage, with **over 70% higher throughput and TFLOPS per GPU**. These numbers show that the B200's performance gains translate directly to faster training times for large-scale models.
