[請益] DDR5 6000/CL30 vs 6400/CL32

最近在看DDR5的價格,以64GB來說,
6000/CL30 < 6400/CL32,兩者的價差可以到1000台幣左右~
仔細計算一下,考慮一筆access的時間
1/6000*30cycle == 1/6400*32cycle 時間完全一樣
再加上時脈快的話比較耗電大、積熱多,感覺相比之下6400/CL32一無是處啊@@
請問板上大大上面是否有什麼因素是我沒有考慮到的地方呢?
威剛的網頁
DDR5 的 CAS 延遲從 36 開始,高於 DDR4。但更快的速度抵消了更高的CAS延遲。
這意味著實際的延遲(以奈秒為單位)僅略高於DDR4。

感恩大家<(_ _)>
ps. 3200/CL16延遲和6400/CL32一樣,對家用來說DDR4升到DDR5不就假升級= =a
要不是現在是目前在盤點的主板強迫換,不然DDR4用好用滿就行了吧Orz
