2700X搭配DDR4 3200先前測試AIDA64 Memory Write - 44133 MB/s
已經比較過AIDA64最新兩個版本，3600與3700X這部分測出來頻寬還是差不多
不知道是軟體支援度還是架構設計問題，希望未來可以透過更新BIOS或軟體改進

Guru 3D的測試中有提到
"You will have noticed that the Ryzen 3000 processors with up to 8 cores make use of one CPU die. Here the write performance is halved. According to AMD, this is normal behavior. They claim that client workloads do very little pure writing, so the CCD/IOD link is 32B/cycle while reading and 16B/cycle for writing. This allowed AMD to save power and area inside the package to spend on other, more beneficial areas."
8核以下的Ryzen 3000 CPU，因為只有一個CPU die所以記憶體寫入的效能會受影響，而12核的3900X不會有這種現象
