This Chinese Company Destroyed The DDR5 RAM Prices Over Night - $500 to $50!

Main summary

Key takeaways

Technology

Technological and market concepts in the video

  • Why DDR5/DRAM prices spiked: The video attributes the major DRAM price jump to the AI-driven shift toward HBM (High Bandwidth Memory), which is physically and manufacturing-intensive compared to standard DRAM.
  • HBM manufacturing bottleneck: Producing HBM consumes far more wafer capacity than regular DRAM (e.g., Micron’s claim that 1GB of HBM uses ~3× the wafer capacity of regular DRAM), contributing to DRAM shortages for consumer/PC/server use.
  • Impact of the “big three” focusing on HBM: The video names Samsung, SK Hynix, and Micron as controlling 90%+ of DRAM, and describes how they redirected capacity toward HBM—reducing supply of commodity DDR5 and LPDDR5X.
  • Secondary consequences: DDR5 kits are described as rising from ~$149 to $239 for a 32GB kit within about a month; some components reportedly saw extreme spikes (e.g., up to “1,000%” in rare cases), and some vendors reportedly removed certain high-memory configurations from shelves.

Product/feature focus: what CXMT is making

  • Company identity: CXMT (Changxin Memory Technologies), based in Hefei, China, founded in 2016.
  • Claimed scale and market momentum: By late 2025, it’s described as reaching roughly 5–7% global DRAM share, up from near-zero in 2020, with production of roughly 280k–300k wafers/month.
  • Process maturity vs incumbents: CXMT’s technology is estimated to be ~2–3 years behind leaders (e.g., 16nm-class vs Samsung’s 12nm range).
  • DDR5 and LPDDR5X lineup (the “commodity RAM” angle):
    • At a late-2025 expo, CXMT reportedly showed DDR5 up to ~8,000 MT/s across 16Gb and 24Gb densities.
    • It also reportedly showed LPDDR5X up to ~10,667 MT/s for phones/laptops.
    • It highlights support for multiple module types: UDIMM, SODIMM, RDIMM, plus server/laptop variants.
    • It claims “G4 DDR5” chips were spotted in retail kits from Gloway, implying the parts are shipping, not just demos.

Core “fix”/strategy analysis (why prices might fall)

  • CXMT’s approach is not top-end performance; it’s affordability + volume:
    • The video argues CXMT’s advantage is price competitiveness, not beating Samsung/Micron on bleeding-edge performance.
    • It cites memory analyst Jim Handy, who claims incumbents earn very high DRAM margins (around ~80% gross margins). The implication: even if CXMT’s manufacturing costs are higher, it can still undercut incumbents and profit.
  • What this means for consumers: Since CXMT targets the DDR5/LPDDR5X commodity categories the incumbents deprioritized, it frames CXMT as filling the “empty shelf” and creating downward price pressure—especially for mainstream PC/server RAM.

Numbers/review-style “evidence” presented

  • Financial growth:
    • Q1 2026 revenue: ~50.8 billion won (~$7.5B), up 719% YoY.
    • First annual profit allegedly achieved in 2025.
    • Operating margins reportedly rising toward ~70%.
  • IPO/capital raised:
    • July 2026: CXMT listed on Shanghai Star Market, pricing at 8.66 yuan/share, raising about 57.9 billion yuan (~$8B).
    • Valuation mentioned: roughly ~$80B.
  • Capacity plans:
    • Target: ~420k wafers/month by 2027, followed by higher growth projections by 2030 and 2035.

The “catch”: why HBM/AI memory is still unresolved

  • Commodity RAM vs AI memory split:
    • The video claims CXMT has “mostly solved” commodity RAM (DDR5, LPDDR5X).
    • It says CXMT has not cracked HBM yet (the AI memory that sparked the crisis).
  • HBM3 progress but low yields:
    • It references 12-layer HBM3 and sample shipments to Huawei for Ascend AI chips.
    • However, estimated HBM yields are ~10–25%, described as too low for large-scale commercial sales.
  • Competitive and regulatory headwinds:
    • Incumbents are described as racing toward HBM4.
    • The video mentions a US export ban affecting EUV lithography machines, which it says slows CXMT’s ability to close the process gap.

Overall conclusion given by the video

  • CXMT is portrayed as a meaningful contributor to DDR5/LPDDR price relief, but still a promising (not yet dominant) challenger in the HBM/AI segment.
  • The video frames increased competition—after decades dominated by three companies—as likely to benefit buyers through lower pricing, assuming CXMT meets yield and ramp targets.
