Summary

The Intel Celeron E3400 was once a quite reliable processor for everyday computing tasks. It was based on the Wolfdale architecture and manufactured using the 45-nanometer process. This then-advanced manufacturing technology enabled good energy efficiency and moderate heat generation. With its 1 MB Level 2 cache, the Intel Celeron E3400 provided noticeably fast data access.

This contributed significantly to overall system responsiveness in simple applications. It represented a cost-effective and stable choice for many office and home PCs. The maximum memory bandwidth of 17 GB/s always reliably supported the necessary data flows. We've noticed that some of these processors are still performing their duties in older systems today.

This speaks to their longevity and solid construction back then. The Intel Celeron E3400 was ideal for web browsing and basic word processing.
