Atom C3338 Details

Built on Intel's Goldmont microarchitecture at a 14 nm process, the Atom C3338 is a modern embedded processor designed for low-power, high-efficiency applications. Released in 2026, it is part of Intel's 3000 Series and is tailored for network and enterprise storage solutions, where power efficiency and thermal control are critical. Despite being a relatively recent release, its position in the broader CPU landscape is modest, reflecting its role as a specialized, power-constrained device rather than a high-performance contender.

The Atom C3338 features two cores and two threads, with a base clock of 1.5 GHz and a turbo frequency of 2.2 GHz. It is packaged in an FCBGA-1310 format, a compact design suitable for embedded systems and small-form-factor devices. The processor supports DDR3L-1600 and DDR4-1866 memory, with a maximum capacity of 131 GB and a memory bandwidth of 13.91 GiB/s. It includes 0.109 MiB of L1 cache—0.0469 MiB for L1D and 0.0625 MiB for L1I—and a 4 MiB L2 cache, which aids in reducing latency for frequently accessed data. The TDP of just 9 W underscores its focus on energy efficiency, making it ideal for systems where thermal output and power consumption must be minimized.

The processor supports a range of advanced technologies, including Intel's Enhanced SpeedStep and Turbo Boost 2.0, which dynamically adjust clock speeds to optimize performance and power usage. It also includes hardware virtualization features such as Intel VT-x and VT-d, along with extended page tables (EPT) and memory protection extensions (MPX), enhancing its suitability for virtualized environments. The inclusion of AES-NI and SHA extensions ensures strong encryption performance, while support for x86-64 and multiple instruction set extensions allows it to run a broad range of software.

In benchmark testing, the Atom C3338 achieves an overall score of 4018, ranking #1873 out of 2060 processors. Its single-core performance scores 3801, placing it at #1889, and its multicore score is 4343, ranking #1604. While these results are competitive with some low-power mobile and embedded CPUs like the A8-7100 and Athlon 7850, they fall significantly short of mainstream desktop and server processors. Notably, its multicore performance outpaces its single-core score, suggesting better scaling in multi-threaded workloads, though its overall capabilities remain constrained by its low TDP and dual-core design.

As of March 2026, the Atom C3338 occupies a niche in the embedded market, where its low power consumption and integrated features make it a viable option for network appliances, storage gateways, and edge computing devices. It is not intended for general-purpose computing or high-performance tasks but excels in environments where sustained operation, minimal heat generation, and compact design are paramount. For users requiring integrated graphics, this processor lacks a GPU, relying instead on external or system-level solutions.
