"When we open the I9500 model, the most surprising discovery is that of Intel’s mobile communication components earning design wins for the baseband and corresponding transceiver. This Galaxy S4 uses Intel’s PMB9820 baseband processor, which we surmise is from their X-GOLD 636 reference design. This baseband is optimized for EDGE, WCDMA and HSDPA/HSUPA bands. The transceiver IC is the PMB5745, which we believe is their SMARTi UE3 RF transceiver. This is the first major design win we’ve seen for Intel since they lost their lucrative sockets in the Apple iPhone to Qualcomm. However, it should be noted that the Qualcomm does have the design wins in the GT-I9505 model, which will be readily available in the US and Canada."
