tablets support them. Because SoC systems (explained in the following section) are
integrated circuits with fixed features, you will need to check if that feature you
would like to have is in the specification list of the tablet you want to buy. Typically
the feature is not supported if it is not listed. You can always contact us for more
information.
How different can dual core solutions be?
The two most important components in a tablet contributing to performance are
CPU and GPU. They are typically integrated on the mainboard together with memory
modules. These integrated systems are called SoC (System on Chip) integrated
circuits. There are more than a dozen tablet SoC brands on the market, such as Tegra,
Rockchip, Allwinner, etc. ValuePad VP111 and VP112 use Rockchip dual core CPUs
and powerful GPUs.
An excellent SoC from Rockchip, RK3168 (in VP112) adopts 28nm technology. Of all
dual core CPUs on the market, it consumes least power and generates least amount
of heat. Also thanks to its 28nm technology and GPU PowerVR SGX540, the same as
the GPU in IPADs, Antutu score of VP112 is around between 10000 and 12000.
New comer RK3026 (in VP111) is another excellent dual core SoC that scores 10000
or higher in Antutu X 4.03. Its performance in CF-Bench is equivalent to NVIDIA's
Tegra 250 in Iconia Tab A500. In Nenamark2, it averages 51.5fps.
Following table compares some popular dual core SoC systems that you may find on
the market. (
