Atom Z3775 Details

Ranked #1996 of 2060 in overall performance, the Intel Atom Z3775 sits near the bottom of the broader CPU hierarchy, trailing closely behind its peers like the Athlon X2 BE-2400 and Intel Atom x5-Z8500. While it shares a similar score with some of its contemporaries, its single-core performance is particularly weak—ranking #2007 of 2060—indicating that it struggles to deliver strong performance in tasks that rely on individual core speed. In contrast, its multicore score of 4304 places it at #1746, a slight improvement but still well below mainstream processors. This performance gap is most pronounced when compared to modern desktop and mobile CPUs, where even entry-level models significantly outperform the Z3775 in both single and multi-threaded workloads.

The Atom Z3775 is built on Intel’s 22 nm process and uses the Silvermont microarchitecture, which was designed for power efficiency rather than raw performance. It features four cores and four threads, running at a base frequency of 1.46 GHz with a turbo boost up to 2.3 GHz. Despite the modest clock speeds, the processor includes a range of modern instruction set extensions such as AVX2, SSE4.1, SSE4.2, AES-NI, and VT-x, which enhance its ability to handle encryption, virtualization, and multimedia workloads. However, these features are offset by its low TDP of 15 W and limited memory bandwidth of 17.1 GB/s, which restricts its scalability.

Integrated into the Z3775 is Intel’s HD Graphics GPU, capable of running at a base frequency of 311 MHz and bursting up to 1 GHz. It supports up to three displays and can utilize up to 8 GB of system memory as shared graphics memory. While this makes the processor suitable for basic multimedia and light productivity tasks, it falls far short of supporting modern gaming or high-resolution video editing.

In terms of memory, the Z3775 supports LPDDR3 1066 MHz with a maximum capacity of 4 GB across two channels, limiting its use in memory-intensive applications. It uses the UTFCBGA1380 socket, which is common in embedded and mobile devices, and supports PCIe 2.0 with up to 10 lanes, though configurations are limited to 4x1, 1x4, and 1x2. The lack of ECC memory support further reduces its viability in professional or server environments.

As of March 2026, the Atom Z3775 remains a legacy device, best suited for low-power, non-demanding applications such as basic web browsing, media playback, or embedded systems. Its performance is no longer competitive with modern processors, even in the low-end market, and it is primarily found in older tablets, netbooks, or industrial devices where power efficiency outweighs performance. For users seeking better performance, even a modest upgrade to a modern Intel Core or AMD Ryzen processor would offer a significant leap in both single-core and multicore performance.
