Since its establishment, Onerugged has been at the forefront of rugged computing solutions, consistently launching high-performance devices. Among these, the M82A, a rugged 8-inch tablet powered by the 12th Gen Intel Core i5-1235U processor, represents a significant technological leap. Known for its powerful performance and durability, Onerugged's tablets have garnered praise from industry users. Previously, Onerugged launched rugged tablets ranging from 10.1-inch to 14-inch, where the larger sizes allowed for better performance release. However, the question arises: can such a powerful processor work effectively within a smaller footprint? The M82A breaks this limitation, providing users with the highest performance in a compact, 8-inch rugged tablet.
Let's begin with the internal structure. When we remove the back cover, we can see the design changes that set the M82A apart from other 8-inch rugged tablets. The most notable modification is the L-shaped motherboard design, a first for Onerugged's 8-inch rugged tablets. This unique layout helps save space, making room for more components like the battery, and also paves the way for efficient cooling systems and fan module integration.
In addition, the M82A uses a 12-layer circuit board layout, allowing for more components to fit in a compact space without sacrificing performance or functionality. The integration of interfaces directly on the motherboard's right edge, as opposed to using interface boards, further enhances the overall design and maximizes space utilization.
The M82A is powered by the Intel® Core™ i5-1235U or i7-1255U processor, featuring a 10-core design that includes two performance cores running at speeds of up to 4.4GHz/4.7GHz, and eight energy-efficient cores at 3.3GHz/3.5GHz. Coupled with the Intel® Iris® Xe Graphics, the tablet is more than capable of handling heavy workloads, demanding tasks, and intensive applications.
During benchmark tests, the M82A showed outstanding performance. For example, in Geekbench testing, the i5-1235U variant scored 5064 single-core and 21309 multi-core, representing an increase of approximately 90% in single-core performance and 182% in multi-core performance compared to a competitor's 8-inch rugged tablet with an i5-10210Y processor.
In the 3D Mark test, the M82A achieved an impressive score of 96084, maintaining strong performance across all categories. The efficient power consumption of the 12th Gen Core processor ensures that the M82A operates optimally in productivity environments while managing heat and power efficiently.
With a high-performance processor, heat generation becomes a concern. Onerugged has integrated an advanced active cooling system into the M82A to keep temperatures under control. Featuring a large copper heat sink, heat pipes, and cooling fins, the system ensures effective heat dissipation for the CPU, GPU, and RAM.
The M82A also utilizes high-conductivity thermal pads (0.2mm thick, with a thermal conductivity of 6W/MK) to ensure efficient heat transfer from the high-temperature components to the cooling system. This robust design ensures that even under heavy loads, the tablet remains cool, maintaining a temperature range that allows it to function efficiently without overheating.
One of the standout features of the M82A is its IP67 rating, making it dustproof and waterproof. Unlike previous Onerugged tablets that were rated IP65 (protecting against water jets), the M82A can withstand complete submersion in water for short periods without affecting its functionality.
This upgrade is particularly important for outdoor workers who require reliable performance under harsh conditions. The M82A achieves this superior waterproofing through several methods, including physical sealing with rubber rings, an isolated fan cavity with IP67-rated components, and specialized coatings on critical areas.
A common issue with smaller rugged tablets has been limited battery life due to their compact size. However, the M82A has solved this problem by incorporating a 7.6V/5700mAh battery, offering a 35% improvement in battery capacity over similar-sized devices.
Even with this large battery, the M82A maintains high performance while providing sufficient runtime for demanding tasks. In our testing, with a brightness of 300 nits and sound at 70dB, the M82A can continuously play 1080P videos for 6.8 hours, which is on par with larger rugged tablets.
In summary, the M82A is a true "all-rounder" rugged tablet. It successfully combines the power of a 12th Gen Intel Core processor with an enhanced cooling system, a waterproof IP67 rating, and a large battery capacity—all packed into an 8-inch form factor. Despite its small size, the M82A performs exceptionally well in every aspect, proving that a compact design does not have to compromise on power or durability.
For users who need a smaller, more portable device without sacrificing performance, the M82A sets a new standard in the rugged tablet industry.
