Atom x5-Z8330 Details

The Intel Atom x5-Z8330 stands as a representative of the low-power, fanless computing segment, designed for entry-level tablets and portable devices. Released in 2015, this processor is now over eight years old, reflecting its role as a foundational component in the early wave of modern mobile computing. Despite its age, the x5-Z8330 remains notable for its 14 nm manufacturing process and integrated graphics, offering a balance of performance and power efficiency suitable for basic productivity and media consumption tasks.

Built on Intel's Silvermont microarchitecture, the Atom x5-Z8330 features four cores and four threads, delivering a base clock of 1.44 GHz and a turbo frequency of up to 1.86 GHz. This modest frequency range is complemented by a 18 W TDP, which allows the processor to operate without active cooling, making it ideal for compact, lightweight systems. The CPU supports DDR3L-RS 1600 memory with a maximum capacity of 2 GB and a bandwidth of 12.8 GB/s, limited to a single channel. While these specifications are outdated by modern standards, they were competitive at the time for low-cost, low-power applications.

The integrated HD Graphics 400 GPU provides basic graphics acceleration, operating at a base frequency of 200 MHz and capable of reaching a burst frequency of 500 MHz. It supports up to two displays and is sufficient for HD video playback and light gaming. The processor also includes a wide range of instruction set extensions, including SSE, AVX, AES-NI, and virtualization technologies such as VT-x and VT-d, ensuring compatibility with a broad software ecosystem.

In benchmark testing, the Atom x5-Z8330 achieves an Overall Score of 4145, placing it at #1749 out of 2060 processors, with a Singlecore Score of 3569 (#1994) and a Multicore Score of 5009 (#637). These results indicate that while the CPU is capable in single-threaded workloads, it significantly lags behind modern processors in multi-core performance. Its multicore performance is notably stronger than its single-core performance, suggesting that the four-core design provides a meaningful advantage in parallel processing tasks, albeit still limited by the aging architecture.

As of March 2026, the Atom x5-Z8330 is best suited for legacy devices, low-power tablets, or embedded systems where power efficiency and cost are more critical than raw performance. It competes with older low-end processors like the Celeron N2840 and Athlon II X2 260u, but falls well behind current mainstream and high-performance CPUs. While it is no longer relevant for demanding computing tasks, it remains a practical option for basic computing needs in energy-constrained environments.
