顯卡功耗沒跑滿就是CPU瓶頸嗎? - 3C

看極客灣測3080、3090,一直提到CPU瓶頸,判斷標準似乎是看顯卡的功耗(而非使用率
),例如一張卡正常能吃300W,但遊戲內只有270W,代表CPU瓶頸。
先說配備:
3500x@4Ghz
2070@2.04Ghz
我玩2款遊戲,pubg和cod:mw,同樣在2K下跑,pubg(顯卡)在210W左右,cod只有180W,
這代表3500x跑cod已經瓶頸了嗎?!
cod遊戲中CPU佔用率在60%上下,開啟遊戲時會衝到100%
最近會升級3600,到時候再來回報功耗狀況。
p.s不要問我3500x為什麼只有4G,我非洲人。
我的問題是極客灣這樣講是不是有點問題,但是話說回來怎麼判斷CPU瓶頸也是個問題。

我自己跑死亡擱淺4K
3080有開DLSS跟沒開幀數差不多
但沒開時功耗會到320W有開只有280W上下
明顯是遇到瓶頸了

在那邊問說什麼瓶頸拖累效能的 一律建議直接買新的
