Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent driver update. Has there been any software changes released for the RX 6800 XT in the past month?

Why it matters: Software updates can significantly impact GPU performance. Expected answer: Yes, a driver update was released two weeks ago. Impact on approach: If confirmed, we'd focus on software-related hypotheses.

• Considering the specificity of the 8% decline, I'm curious about the testing methodology. Are these results from a single benchmark or an average across multiple tests?

Why it matters: Understanding the breadth of testing helps validate the issue's consistency. Expected answer: It's an average across three industry-standard benchmarks. Impact on approach: A consistent decline across multiple tests would suggest a systemic issue rather than a benchmark-specific problem.

• Given the nature of thermal performance, I'm wondering about environmental factors. Have there been any changes in the testing environment or cooling solutions used?

Why it matters: External factors could significantly influence thermal performance. Expected answer: No changes in testing environment or cooling solutions. Impact on approach: If confirmed, we'd focus more on internal hardware or software issues.

• Considering potential hardware variations, has this decline been observed across all manufacturing batches of the RX 6800 XT?

Why it matters: Batch-specific issues could indicate a manufacturing or component problem. Expected answer: The decline has been observed in units from multiple batches. Impact on approach: A widespread issue would suggest a design or software problem rather than a manufacturing defect.
