One of the common misconceptions in today's memory market is that once memory modules based on chips from CXMT enter the consumer market, there will be cheaper alternatives to memory sticks running DRAM from the Big Three. While availability of CXMT-powered modules certainly impacts average selling prices, these products are not cheaper than those based on ICs from Micron, Samsung, and SK hynix even in China, as noticed by @harukaze5719.
A 64GB DDR5-5600 RDIMM based on memory from Samsung or SK hynix costs 18,595 CNY ($2,745) at JD.com, whereas a module featuring the same capacity and specification, but using DRAMs from CXMT is priced at 18,999 CNY ($2,805), according to observations by @harukaze5719. It is noteworthy that a Samsung 64GB DDR5-5600 RDIMM made by Samsung and sold by Samsung costs $2,425 at Amazon.com in the U.S.
While the $60 difference seems significant, it is really just 2.2%, which can be considered negligible at these sky-high prices. Nonetheless, many expect CXMT-based memory modules to be cheaper than those carrying chips from Micron, Samsung, or SK hynix, so observing that they are even a bit more expensive than offerings with ICs from renowned manufacturers may be a bit surprising.
Indeed, because CXMT produces memory chips using an outdated fabrication technology, its DRAM ICs consume more power than those made using the latest manufacturing processes, have lower performance potential, and mediocre overclockability. Furthermore, the Chinese government heavily subsidizes both ChangXin Memory Technologies and Yangtze Memory Technologies (YMTC), which enables both to sell their memory at lower prices although their actual costs may be higher compared to those of the Big Three.
As a result, it is reasonable to expect CXMT to charge less for its chips compared to chips from renowned producers. Truth to be told, we do not know CXMT's quotes, they may be as high as those from other manufacturers and the only reason why module producers buy them is that they are the only chips available. Furthermore, companies tend to price products based on what the market will bear, not strictly on production cost or their characteristics. In fact, as everyone is capacity constrained these days, there is little incentive for CXMT to price its DRAMs significantly below those from renowned makers. However, while CXMT may indeed charge less for chips (e.g., because the Chinese government issues an appropriate directive), this lowers costs for module makers, but has a limited effect on retail prices of actual DIMMs or RDIMMs.
Whether potential savings reach end customers depends on market competition, supply-demand conditions, and the pricing strategies of module makers, distributors, and retailers. Furthermore, when prominent companies like Apple, Dell, or Corsair use a memory chip SKU, this one must pass rigorous validation processes and is usually tested in-house, or by contract manufacturers, which adds to costs and somewhat erases the price difference between suppliers.
As a result, CXMT memory chips may make the lives of hardware makers easier, but are not expected to impact the retail prices you pay.
