China-based white-box tablet makers are reportedly approaching MediaTek for the purchase of the chipmaker's integrated MT8125 and 8135 quad-core application processors for tablets, according to industry sources.

　　The move by the white-box tablet makers comes after branded tablet vendors in China and Taiwan have begun using the MT8125 and 8135 solutions for tablets targeting the US99-149 segment, the sources noted.

　　White-box tablet makers currently purchase quad-core solutions mainly from China-based IC vendors including Allwinner Technology and Rockchip Technology, while buying Wi-Fi and Bluetooth chips from Realtek Semiconductor and RDA Microelectronics.

　　The 28nm quad-core solutions from Allwinner and Rockchip are priced at US$4-5, or about 50% lower than the comparable quad-core chips offered by MediaTek, since the chips offered by Allwinner or Rochchip do not support voice communications, said the sources.

　　In order to compete effectively in China and other emerging markets and differentiate products, white-box tablet makers have been forced to adopt MediaTek's quad-core solutions, commented the sources.
