  • For the curious (and lazy):

    According to repair biz iFixit, the issue with the power-frugal LPDDR memory chips is that the lower voltage they operate at calls for more attention to be paid to signal integrity between the CPU and memory. In practice, this has meant shorter track distances on the circuit board, leading to LPDDR being soldered down as close to the processor as possible.

    LPCAMM2 is intended to address this by putting LPDDR onto a circuit board module that is “cleverly designed to mount right up next to the CPU,” with “very short traces to help maximize signal integrity,” the iFixit team explains in a blog and video detailing their hands-on with the ThinkPad P1 Gen 7.
