The Kamrui Essenx E1 follows a Micro-ATX form factor and occupies a compact physical footprint, measuring 128 mm in both width and thickness with a height of just 52 mm, resulting in a total volume of approximately 851.97 cm³. Storage is handled by a 512GB NVMe SSD, which uses the faster NVMe interface rather than a traditional SATA drive, offering quicker data access within that small chassis.
The processor in this unit carries a 6W Thermal Design Power (TDP), reflecting its low-power design, and operates across 4 threads with a base clock speed of 4 x 0.1 GHz and a turbo clock that reaches up to 3.6 GHz. It does not use multithreading and has a fixed clock multiplier of 1 with no unlocked multiplier, meaning clock speed adjustments are not supported. The CPU includes 6 MB of L3 cache (1.5 MB per core), supports 64-bit processing, comes with integrated graphics, and is rated for a maximum operating temperature of 105 °C.
The integrated graphics solution runs at a turbo clock of 1000 MHz and is built on a 10 nm semiconductor process, with PCIe 3 handling the interface connection. It supports DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, covering a solid range of graphics and compute APIs. The GPU can drive up to three displays simultaneously, making multi-monitor setups a viable option within this compact system.
The system comes equipped with 16GB of DDR4 RAM running at a speed of 3200 MHz, providing a single-generation memory configuration suited to the unit's low-power profile.
Wireless connectivity is provided through Wi-Fi 5 (802.11ac) and Wi-Fi 4 (802.11n) alongside Bluetooth 4.2, while wired networking is covered by a single RJ45 Ethernet port. For USB, the unit offers two USB 2.0 ports and two USB 3.2 Gen 1 Type-A ports; there are no USB-C ports of any generation, and neither Thunderbolt 3 nor Thunderbolt 4 is supported. Display output is handled by one HDMI 2.0 port and one DisplayPort output, with no VGA connector present. Audio connectivity includes a 3.5 mm headset jack, though there is no S/PDIF output.
In PassMark testing, the processor scores 5416 in the multi-core benchmark and 1906 in the single-core test, reflecting the performance profile of a low-TDP mobile-class chip. An overclocked PassMark result of 5754 is also recorded, representing a modest uplift over the standard multi-core score.
The CPU is a laptop-type processor that does not use big.LITTLE technology, and it supports a range of instruction sets including MMX, AVX, AVX2, FMA3, F16C, AES, SSE 4.1, and SSE 4.2, along with NX bit for hardware-level memory protection. Memory is handled through a single channel, with a maximum supported capacity of 16GB and a top RAM speed of 4800 MHz; ECC memory is not supported, and there is no external memory slot. The integrated GPU includes 24 execution units, and the unit comes with a one-year warranty.
