HU最近在測試Zen系列CPU的進步時發現5700XT配了1600X在CPU瓶頸的狀況下竟然比3070
配1600X快,因此他做了封鎖的評測來討論到底發生了什麼事。
簡單來說:DX12的環境下,N卡與A卡在一樣的幀數下,N卡會使用更多CPU資源。
例如這張圖,用i3-10100搭配3070與6800,幀數限制60幀,在Shadow of Tomb Raider下
的CPU使用率。

再來是1080p中畫質的Horizon Zero Dawn,當你使用1600X配5600XT,其幀數比3070高不
少:

但是當你加重GPU負載,情況會稍微減小:

2K中畫質,情況幾乎就比較正常但還是可以發現較弱的CPU從5700XT升到3090或6900XT的
比例差很多:

2K全開,基本上就是大家預期的效能成長比例:

看門狗也有類似情況,從1080p中畫質到2k全開:

最後給了兩張圖,假如你買得到顯卡,而又沒有要搭配較新的Cpu,又玩比較容易CPU瓶
頸的遊戲(1080p、2K中特效或是競技類),則同效能下購買A卡會有比較大的提升感。反
之,如果你的CPU夠強,或是你玩的遊戲都是GPU瓶頸,那這個觀察就對你沒什麼用

感想:算力重要還是FPS
