Recently, it turned out that China-based memory maker ChangXin Memory Technologies (CXMT) began to ship DDR5 memory chips. However, according to the findings of a Chinese semiconductor researcher, the die size of CXMT's 16 Gb DDR5 memory IC is 40% larger than that of a competing Samsung chip, which means that it is significantly more expensive to build due to the use of less advanced chipmaking technology. Of course, since the information comes from an unofficial source, take it with a grain of salt, but the technician does deconstruct the DRAM module on video, lending credence to the findings.
CXMT's 16 Gb DDR5 die measures 8.25 × 8.25 mm; therefore, its die size is 68.06 mm^2. By contrast, a modern Samsung 16 Gb DDR5 die measures 6.46 × 7.57 mm and has a die size of 48.90 mm^2.
