Atom x5-Z8500 Details

Built on Intel's 14 nm manufacturing process, the Atom x5-Z8500 represents a significant step in the company's effort to deliver power-efficient computing for mobile and embedded applications. Released in the early 2010s, this processor is now considered an older device by modern standards, though it remains relevant in low-power scenarios. Designed for use in compact systems, the Atom x5-Z8500 features a quad-core architecture with four threads, operating at a base clock speed of 1.44 GHz and capable of boosting up to 1.86 GHz under load. It is packaged in a UTFCBGA1380 socket, typical of Intel's mobile designs, and carries a TDP of 65 W, indicating a focus on performance within a modest thermal envelope.

The Atom x5-Z8500 includes a 64-bit instruction set and supports a range of advanced technologies such as SSE4.1, SSE4.2, AVX2, AES encryption, and Intel's Hyper-Threading. It also supports Intel's vPro platform, enabling remote management and security features suitable for enterprise environments. The processor is equipped with Intel HD Graphics, which operates at a base frequency of 200 MHz and can burst up to 1 GHz, supporting up to three displays. Memory support includes dual-channel LPDDR3-1600, with a maximum capacity of 8 GB and a peak bandwidth of 25.6 GB/s. These specifications reflect its design for lightweight multimedia and general-purpose computing.

In benchmark testing, the Atom x5-Z8500 scores 3,914 overall, placing it at #1,952 among 2,060 CPUs, with a single-core score of 3,646 (#1,965) and a multicore score of 4,315 (#1,711). While these results are competitive with older mobile and low-power processors, they fall significantly short of modern high-performance CPUs. For example, the top-ranked Ryzen Threadripper PRO 9995WX achieves an overall score of 9,492, nearly 2.4 times higher. The processor’s multicore performance is its strongest attribute, ranking higher than its single-core performance, which suggests it benefits more from parallel workloads than from raw clock speed.

Despite its age, the Atom x5-Z8500 remains a viable option for light productivity tasks, media playback, and embedded systems where power efficiency is more critical than raw performance. Its integrated GPU and support for ECC memory make it suitable for industrial or commercial use cases, though it is outpaced by nearly all contemporary processors. As of March 2026, it serves as a legacy solution in niche markets rather than a mainstream choice for new systems.
