I just got asked about the differences between Blackwell systems and Grace Blackwell systems. What's the difference and how much of a performance gap is there between them?

Here's a summary of the key points from the article:
GB200 (Grace Blackwell) is a Superchip: It integrates a Grace CPU and two Blackwell GPUs into a single package.
B200 is a GPU-only module: It's designed to be paired with x86 or ARM CPUs in more traditional server setups.
Performance and Efficiency:
Based on MLPerf Training v5.0 benchmarks, the article concludes:
GB200 systems are approximately 42% more efficient than B200 systems on average. This is especially true in large-scale deployments (100+ GPUs), where the GB200's integrated design and high-speed NVLink interconnect provide a significant advantage.
In smaller, single-node systems (e.g., 8 GPUs), the performance difference is much smaller, around 10-15%.
Use Cases:
Choose GB200 for large-scale AI clusters, training massive models, and when maximum efficiency is the top priority.
Choose B200 for smaller deployments, when you need the flexibility to choose your own CPU, or for mixed AI and HPC workloads.
