写入只有一半是aida64算法问题，实际没有。真只有一半还用过鸡儿。

The above graphic illustrates how Zen 2 makes the CCXs independent of the I/O block. It shows a couple of CCX complexes lashed together via Infinity Fabric to create an 8C16T chip complete with 4MB of L2 and 32MB of L3 cache. This modular CCD is then connected to the I/O chip (cIOD) via a high-speed data fabric capable of reading 32 bytes and writing 16 bytes on each clock cycle. That may cause a problem for the memory write speeds when using processors equipped with single CCD - any Ryzen 3000-series with eight or fewer cores - because the data fabric-to-UMC speed, inside the cIOD, is 32 bytes for reads and writes: they don't match.

再看看5700XT 不到3000的价格  农企在整机6 7千这个档位不光只能用性价比来遮羞  确实能打了
