Hardware Performance
MSI have chosen to use a Allwinner A31s quad-core 1.0 GHz processor to power the Primo 81 which is a budget-focused quad core chip. This is partnered with 1 GB of RAM and a PowreVR SGX544MP2 GPU.
We can see that the Primo 81 performs better than the Acer Iconia A1 in the more graphics intensive tests, whereas the Acer performs better in the more CPU intensive tests.
