Atom Z3740D Details

The Intel Atom Z3740D represents a niche entry in the low-power computing space, designed for ultra-compact devices such as tablets and embedded systems. As of early 2026, this processor is considered quite dated, having been released over a decade ago. Despite its age, it remains relevant in legacy systems and cost-sensitive applications where power efficiency and basic processing capabilities are prioritized over raw performance.

Built on a 22 nm process and based on the Silvermont microarchitecture, the Z3740D features four cores and four threads, operating at a base frequency of 1.33 GHz with a turbo boost up to 1.86 GHz. The CPU is packaged in a UTFCBGA1380 socket and carries a TDP of 65 W, which is relatively high for an Atom processor, indicating a focus on performance over thermal efficiency. It supports up to 2 GB of DDR3L-RS 1333 memory, with a maximum bandwidth of 10.6 GB/s, and is limited to a single memory channel.

The integrated Intel HD Graphics GPU runs at a base frequency of 313 MHz and can burst to 792 MHz, supporting up to two displays. While not suited for modern gaming or intensive graphics workloads, it provides sufficient capability for basic multimedia playback and light graphical tasks. The processor supports a wide range of instruction sets, including SSE4.1, SSE4.2, AVX, AVX2, AES-NI, and Intel's virtualization technologies such as VT-x and VT-d.

In benchmark testing, the Z3740D achieves an overall score of 3833, placing it at #2001 out of 2060 processors evaluated. Its single-core score of 3529 ranks at #2010, while its multicore score of 4290 places it at #1783. These results indicate that the processor is outperformed by most modern CPUs, even in the low-end segment. It falls behind contemporary Atom variants like the Z3775 and Z3740, as well as some older Celeron models.

In the broader context of the top 50 processors across single-core, multicore, and overall performance, the Z3740D is positioned far from the leaders. Top-tier CPUs like the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K exceed its scores by a factor of two or more. The Z3740D's performance is most comparable to early 2010s Atom and Celeron processors, suggesting it is best suited for light-duty computing tasks such as web browsing, office applications, and media playback in devices with minimal thermal and power constraints.

In summary, the Atom Z3740D is a legacy processor that, as of 2026, is best suited for entry-level or embedded systems where cost and power efficiency are more critical than performance. While it supports modern instruction sets and basic graphics capabilities, its age and limited computational power make it unsuitable for demanding workloads or modern applications.
