WIKI 上說 DDR2 SDRAM gives a transfer rate of (memory clock rate) × 2 (for bus clock multiplier) × 2 (for dual rate) × 64 (number of bits transferred) / 8 (number of bits/byte). [1] 但通常 embedded system 不會用 64 bit 通道, 比較常見的 16 bit 或 32 bit. 這個表格裡會用 16 bit.
另外, DDR-4 的效能不佳, 比 DDR-3 沒有太大改進 [2], 某些指標好 13.88% (解壓縮), 播影片 X265 反而變差了 3.68%. 公司同事對它的評價則是更低許多. 不過未來可望能用比 DDR-3 便宜的價格買到一樣容量的 DDR-4.
NAND 的速度參考美光網站 [3], Read 可以到 200 MB/s. 以及 e-world [4].
以上沒說明的部分都是從 WIFI 抄過來.
