Clarifying Questions (5 mins)

• Looking at the product context, I'm thinking about the specific applications driving IPU usage. Could you help me understand the primary use cases and workloads where our IPUs are currently deployed?

Why it matters: Determines which performance characteristics to prioritize for energy efficiency improvements. Expected answer: Machine learning training and inference in data centers and edge computing. Impact on approach: Would focus on optimizing for specific AI workloads rather than general-purpose computing.

• Considering user behavior, I'm curious about the typical deployment scenarios. Are our IPUs primarily used in large-scale data centers, edge devices, or a mix of both?

Why it matters: Influences the design constraints and energy efficiency strategies we can employ. Expected answer: Primarily large-scale data centers with growing interest in edge deployments. Impact on approach: Would prioritize solutions that scale well in data center environments while keeping edge compatibility in mind.

• Regarding our product lifecycle and market position, where do we stand in terms of energy efficiency compared to our main competitors like NVIDIA and AMD?

Why it matters: Helps determine if we need incremental improvements or a radical redesign. Expected answer: We're competitive but not leading; there's room for significant improvement. Impact on approach: Would focus on both short-term optimizations and long-term architectural changes.

• Considering company alignment, what are the specific energy efficiency targets or sustainability goals that Graphcore has set for its next-generation IPUs?

Why it matters: Ensures our solutions align with broader company objectives and market demands. Expected answer: Aiming for a 30% reduction in power consumption while maintaining or improving performance. Impact on approach: Would set clear benchmarks for our solutions and prioritize those with the highest impact on power reduction.
