CXMT DDR5 Memory Hits 8000 MT/s, Performance Gap Under 1% vs Hynix

CXMT DDR5 memory has reached a performance milestone that matters to PC builders chasing high-speed RAM. Domestic chips now match the speed of leading foreign alternatives in real-world gaming tests. This development gives users a viable high-frequency option that does not sacrifice frame rates.

Domestic chips match Hynix speed in real-world gaming tests

The test compares CXMT DDR5 modules against Hynix M-die flagship kits running at 8000 MT/s. The platform uses an Intel Core Ultra 7 270K Plus processor and an RTX 5080 graphics card. We see how these components handle the increased memory bandwidth.

• CXMT Memory Read Bandwidth: 123.32 GB/s
• CXMT Memory Latency: 76.1 ns
• Hynix Memory Read Bandwidth: 124.68 GB/s
• Hynix Memory Latency: 72.2 ns
• Geekbench 6 Score (CXMT): 24576

CXMT memory achieves a read bandwidth of 123.32 GB/s with a latency of 76.1 ns. Hynix kits reach 124.68 GB/s with a slightly lower latency of 72.2 ns. The Geekbench 6 score for CXMT is 24576, while Hynix scores 24790. This results in a performance gap of just 0.86%.

Gaming benchmarks show the two memory types perform almost identically. In Rainbow Six Siege X, the frame rate difference is less than 1% or 5 FPS. Call of Duty 21 and Forza Horizon 5 show a difference of less than 1 FPS. These results confirm that CXMT chips can stabilize at high speeds without noticeable gaming penalties.

We looked at DDR5 Memory closely — see our earlier coverage on ASUS BIOS Update Boosts CXMT DDR5. The test results come from sources including KuaiJiKe and Bilibili UP host Zhi Shi Hua Lai Shi. Specific chip batches and exact processor model details remain unconfirmed in public reports.
