Intel has revised their guidance for their 7nm processors.
Turning to our 7nm technology: We are seeing an approximate six-month shift in our 7nm-based CPU product timing relative to prior expectations. The primary driver is the yield of our 7nm process, which based on recent data, is now trending approximately twelve months behind our internal target. We have identified a defect mode in our 7nm process that resulted in yield degradation. We’ve root-caused the issue and believe there are no fundamental roadblocks, but we have also invested in contingency plans
to hedge against further schedule uncertainty. We’re mitigating the impact of the process delay on our product schedules by leveraging improvements in design methodology such as die disaggregation and advanced packaging. We have learned from the challenges in our 10nm transition and have a milestone-driven approach to ensure our product competitiveness is not impacted by our process technology roadmap.
