I read that the cr25 is a single core cpu. https://www.cpu-world.com/CPUs/Bobcat/AMD-G%20Series%20G-T30L%20-%20GET30LGBB12GTE.html
It appears that some of the confusion is caused by the fact that Cyberoam at some point updated their hardware and used the same model names. Looking at ebay you can see some CR25(w)iNG models that are rebranded AEWIN SCB-6901 devices and others that use the newer AEWIN SCB-6979 device. To tell the difference you'll need to see the Model number on the label on the bottom of the device.
