Atom Z670 Details

With a TDP of just 3 watts, the Intel Atom Z670 stands as a prime example of ultra-low-power mobile computing, designed for devices where energy efficiency takes precedence over raw performance. Released in April 2011 as part of Intel's Atom lineup, the Z670 is built on the Bonnell microarchitecture and fabricated using a 45 nm process, reflecting the early days of mobile processor design focused on minimal power draw. Despite its age—over 12 years since launch—the processor remains notable for its integration of the PowerVR SGX535 GPU and its ability to support DDR2-800 and DDR-400 memory, making it a key component in early tablet and netbook platforms such as the Oak Trail platform. As of March 2026, it resides near the bottom of modern performance rankings, a testament to both its era and its intended market segment.

The Atom Z670 features a single core with two threads enabled via Intel's Simultaneous Multithreading (SMT) technology, allowing it to handle light multitasking more efficiently than a single-threaded core. It operates at a base frequency of 1.5 GHz, with a clock multiplier of 8 and a bus speed of 400 MT/s, connected via the cDMI interface. The processor includes 512 KB of L2 cache, though it lacks an L1 cache hierarchy as detailed in the specifications, and supports up to 2 GB of memory with a maximum bandwidth of 2.98 GiB/s. Its integrated PowerVR SGX535 GPU runs at 400 MHz and supports a single display output, suitable for basic multimedia tasks but not for modern graphics-intensive applications.

In benchmark testing, the Atom Z670 achieves an overall score of 3600, placing it at rank #2053 out of 2060 processors, with a single-core score of 3200 (#2052) and a multicore score of 4200 (#2010). These results reflect its position as a low-end mobile processor, comparable to other Atom models like the Z520 and N270, but slightly faster than the N2800 and E3815. While it outperforms some older Celeron and Atom variants, its performance is dwarfed by modern CPUs, even in the mobile segment. The multicore performance is notably stronger than single-core, indicating that the processor's architecture benefits slightly from threading, though this is limited by the constraints of its single core.

Technologically, the Z670 supports key features such as Enhanced SpeedStep Technology (EIST) for dynamic frequency scaling and Intel's integrated graphics solution, though it lacks support for modern instruction sets like SSE4. The processor is designed for use in compact devices such as tablets and ultra-portable laptops, where power consumption and thermal management are critical. Its low voltage range (0.7 V to 1.15 V) and compact 65 mm² die area further underscore its design for efficiency over performance. While it has no ECC memory support and a locked clock multiplier that limits overclocking, it was well-suited to its intended use case at the time of release.

In summary, the Intel Atom Z670 is best suited for basic computing tasks such as web browsing, document editing, and media playback in lightweight devices. As of March 2026, it serves as a historical reference point in the evolution of mobile processors, highlighting the shift from power-efficient, low-performance designs to the high-performance, multi-core architectures that dominate today’s market. Its relevance is now primarily in retro computing, embedded systems, or niche applications where legacy compatibility and minimal power draw are paramount.
