CXMT DDR5 Hits 9,000 MT/s, Rivals Top Memory Makers

Memory manufacturers are pushing the performance envelope for PC builders, and Chinese vendor CXMT has reached a new milestone. The company achieved DDR5 speeds of 9,000 MT/s on AMD platforms, a level that previously belonged to established leaders like Micron, SK Hynix, and Samsung. This breakthrough matters because it proves domestic production can compete with global giants in high-performance memory. Buyers looking for faster RAM options now have a viable alternative to traditional suppliers.

Chinese vendor matches top three manufacturers with 48GB kit

The specific product tested is a 48GB kit using 24Gx2 memory chips. It operated at a frequency of 4,507 MHz, which corresponds to the 9,000 MT/s double data rate. The testing environment included a Colorful iGame X870E VULCAN W OC motherboard and an ASUS motherboard. These results demonstrate that the memory modules function correctly on standard consumer hardware without requiring custom or experimental platforms.

Key Specifications

• Speed: 9,000 MT/s
• Frequency: 4,507 MHz
• Capacity: 48GB (24Gx2)
• Latency: CL30 (at 6,000 MT/s)
• Process Node: 17nm

Beyond raw speed, the memory shows impressive latency characteristics. The kit ran at CL30 latency when set to 6,000 MT/s. Testing also revealed CL28 latency capabilities, matching the performance of the top three memory manufacturers. CXMT uses a 17nm process node for its DDR5 production. This manufacturing approach has allowed the company to achieve a 90% yield rate.

The 90% yield rate is particularly significant when compared to industry standards. It is only 2 to 3 percent lower than the yield Samsung achieves with its 10nm DDR5 production. This gap suggests that CXMT has matured its manufacturing process rapidly. The performance and yield metrics indicate that the company is ready to supply high-end memory kits to the market.

We have been tracking DDR5 Memory closely — see our earlier coverage on ASUS BIOS Update Boosts CXMT DDR5. That previous report highlighted how BIOS updates can further enhance speeds for these same modules. The current achievement confirms that the hardware itself is capable of exceeding 8,000 MT/s with proper tuning. The combination of high speed, low latency, and strong yields positions CXMT as a serious contender in the global memory market.
