AMD processors help congatec to higher processing/Watt metrics

Based on the 2nd generation AMD Embedded G-Series SOC "Steppe Eagle" processors, congatec's latest Qseven and COM Express Computer-on-Modules boost performance per Watt and lower power consumption

Compared to the current AMD Embedded G-Series SOC platform, these modules based on 2nd generation AMD Embedded G-Series SOC (System-on-Chip) processors provide higher performance and a lower power draw thanks to an improved Jaguar+ CPU architecture and AMD Radeon 8000 graphics core. Graphics engine speed has been increased up to 800 MHz and the DDR3 interface up to 1866 MT/sec. A new function of the G-Series includes Core Boost Frequency to ensure appropriate processor overclocking.

congatec designed these Qseven and COM Express modules for low-power embedded applications. This fanless module design is suited to cost-sensitive applications in the control and automation industry, digital gaming, communication infrastructure and graphics-intensive devices such as thin clients, digital displays or medical-imaging equipment.

In the Qseven standard, congatec supports two new processors from the AMD Embedded G-Series SOC platform: the dual-core AMD GX-212JC 1.2 GHz with a boost frequency of 1.4 GHz (1MB L2 cache ) and 6W TDP; and the quad-core AMD GX-412HC 1.2 GHz with a boost frequency of 1.6 GHz (2MB L2 cache) and 7W TDP. For the COM Express Compact Type 6 standard, there is also the quad-core AMD GX-424CC 2.4 GHz (2MB L2 cache) with a TDP of 25W.

Thanks to onboard Error Correction Code (ECC) memory support, the module is suitable for safety-critical applications. Depending on the design, the module comes with up to 4 GB of ECC DDR3L RAM to allow for the correction of single and double bit errors. More serious errors, that cannot be corrected automatically, will cause the module to halt so as to avoid a system malfunction.

The integrated AMD Radeon graphics supports DirectX 11.1 and OpenGL 4.2 for fast 2D and 3D image display. OpenCL 1.2 is also supported, enabling the execution of program code by the GPUs. The range of available graphics interfaces includes LVDS and DisplayPort 1.2 as well as DVI/HDMI 1.4a for the direct control of two independent displays.
