Atom E3815 Details

Ranking #2057 of 2060 in overall performance, the Intel Atom E3815 sits near the bottom of modern CPU benchmarks, reflecting its age and entry-level design. Released in October 2013 as part of Intel's Bay Trail-I family, this processor was built for ultra-low-power mobile devices such as netbooks and embedded systems. Its 22 nm manufacturing process and 5 W TDP underscore its focus on energy efficiency rather than raw computational power. Despite its historical significance in the mobile space, the E3815 is now obsolete by current standards, with no support for modern instruction sets like AVX or SSE4.2, limiting its usefulness in today’s software ecosystem.

The Atom E3815 features a single core with a base frequency of 1.467 GHz and a locked clock multiplier, meaning it cannot be overclocked. It includes 512 KB of L2 cache per core and supports DDR3 memory, though the exact memory bandwidth and maximum capacity are unspecified. The processor uses a BGA1170 package and operates at a very low 5 W TDP, making it suitable for fanless systems and compact devices where power consumption is critical. The integrated HD Graphics GPU provides basic visual output, though it lacks support for modern graphics APIs and is not capable of handling contemporary gaming or video editing workloads.

In benchmark tests, the E3815 achieves a single-core score of 3,140 and a multicore score of 4,239, placing it among the lowest-performing processors in its category. Its overall score of 3,580 confirms its position as a low-end, budget-oriented CPU. Compared to its immediate neighbors, it trails behind slightly older models like the Atom Z520 and Atom 230, both of which have higher clock speeds and better performance metrics. This suggests that even within the Atom lineup, the E3815 was one of the least powerful variants.

While the E3815 may have been sufficient for basic tasks like web browsing and document editing in its time, it is now largely irrelevant in the context of modern computing. Its lack of modern features, such as ECC memory support and simultaneous multithreading, further diminishes its appeal. The processor’s primary use case today is in legacy systems or specialized embedded applications where power efficiency and cost are more important than performance. As of March 2026, it remains a relic of an earlier era in mobile computing, offering little value in new builds or upgrades.

In conclusion, the Intel Atom E3815 is a niche processor designed for ultra-low-power environments. Its minimal performance, outdated architecture, and lack of modern features make it unsuitable for general-purpose computing in 2026. While it holds historical interest as part of Intel’s early efforts in low-power mobile design, it is best suited for legacy systems or educational demonstrations of early Atom processors. For users seeking anything beyond basic functionality, a more modern and capable CPU is strongly recommended.
