The current PC market sees a rise in demand for M-ITX solutions. But with the with ATX and M-ATX motherboards already flooded in the market , will going small means you have to sacrifice in performance? Read on to find out more.
The Contenders
For this experiment, we shall be using the new range of AMD’s 785G chipset board recently released by J&W. J&W, one of the leading motherboard manufacturers, is also one of the pioneers in making Mini-ITX solution, which was once only exclusive to the industry partners, available to the general consumers.

J&W recently released three motherboards under the AMD’s 785G + SB710 chipset, mainly the JW-A785GM-D3 (ATX), JW-A785GMT-EXTREME (MATX), and MINIX™ 785G-SP128MB (MITX). We shall be using the JW-A785GMT-EXTREME and the MINIX™ 785G-SP128MB for comparison.
The 785G chipset, with the ATI Radeon™ HD 4200 Graphics, is the latest from AMD to provide power-efficient, features and performance platform at incredible value.
