The Gigabyte GA-C847N is a Mini-ITX motherboard with a soldered Celeron 847 CPU. It uses the Intel NM70 chipset and has one PCI slot. Let’s take a look at this little board.
The Celeron 847 is derived from the mobile version of the second generation Core i3 (Sandy Bridge) CPU, aimed at low-cost laptops. Its nominal clock is 1.1 GHz and it has 2 MiB of L3 memory cache. The main difference to a mobile Core i3 processor is the lack of the Hyper-Threading technology. It also has a smaller amount of L3 memory cache, since second-generation Core i3 mobile CPUs have an L3 memory cache of 3 MiB.
The NM70 chipset, despite its name (that looks like an Atom family chipset), is a low TDP version of the HM75 chipset.
