Atom Z3740 Details

The Intel Atom Z3740, launched in September 2013, is a mobile processor from the Bay Trail-T family, designed for low-power devices such as tablets and ultra-portable laptops. While it was once a competitive option in the mobile space, the Z3740 is now over a decade old and reflects the limitations of early 2010s mobile computing architecture. Despite its age, the processor retains relevance in niche applications where power efficiency and basic computing tasks are prioritized over raw performance.

Featuring four cores and four threads, the Atom Z3740 operates at a base clock of 1.33 GHz and can boost up to 1.86 GHz, making it suitable for light multitasking and general productivity. Built on Intel’s 22 nm process, it consumes just 18 W of power, contributing to extended battery life in mobile devices. The chip supports dual-channel LPDDR3 memory at 1066 MT/s, delivering a maximum memory bandwidth of 17.1 GB/s, and includes 2 MB of L2 cache—typical for its era and market segment.

Integrated into the design is Intel’s HD Graphics, which runs at a base frequency of 311 MHz and can reach up to 500 MHz in burst mode. It supports up to two displays and is capable of handling basic multimedia tasks, though it falls far short of modern integrated graphics solutions. The processor uses the FC-BGA1380 package and is socketed under the UTFCBGA1380 designation, ensuring compatibility with devices designed for this form factor.

In terms of features, the Atom Z3740 supports a broad range of instruction sets, including SSE4.1, SSE4.2, AVX, and AVX2, allowing it to handle a variety of workloads efficiently. It also includes AES-NI encryption, virtualization technologies like VT-x and VT-d, and enhanced power management features such as EIST and TXT. However, it lacks Simultaneous Multithreading (SMT), limiting its ability to fully utilize all four cores under certain workloads.

Benchmarking data reveals that the Atom Z3740 scores 3,856 overall, placing it at #1989 out of 2060 processors in the PassMark rankings. Its single-core score of 3,542 ranks it #2008, while its multicore score of 4,326 lands it at #1668. These results indicate that the Z3740 is competitive with some older dual- and quad-core processors but lags significantly behind modern CPUs. For example, it trails behind the Core i3-3227U and Athlon II X3 425 in multicore performance, while its single-core performance is comparable to the Atom Z3775, a slightly more powerful variant in the same lineup.

As of March 2026, the Intel Atom Z3740 is best suited for legacy systems, entry-level tablets, or embedded applications where energy efficiency and cost are more important than performance. It is no longer viable for demanding tasks such as video editing, gaming, or modern software development. Its performance is overshadowed by today’s mainstream and high-end processors, which now exceed 7,000 in single-core and 12,000 in multicore scores. Nonetheless, the Z3740 remains a testament to Intel’s early efforts in creating low-power, multi-core mobile processors.
