反其道而行?UserBenchmark降低多核心測試權重 4核心Core i3勝8核心Ryzen 7
GARY ·2019-07-25
大家都知道,任何測試都不可能完全精準地衡量產品效能,亦不可能讓所有人都信服,特
別是產品本身也在不斷變化。以處理器而言,近兩年核心數量不斷猛增,單執行緒、多執
行緒效能到底哪個更重要?該如何平衡測試?

UserBenchmark並不是一個特別常見的基準測試軟體,但權威性算得到普遍認可。現在,
UserBenchmark突然調整了處理器測試標準,大大降低多核心成績的比重,結果出現了怪
異的變化。
UserBenchmark處理器測試成績有三個子項,分別是單核心、四核心、多核心,之前三者
於總成績中的比重分別為30%、60%、10%,看起來很合理,同時以Core i7-7700K作為基準
線(100%)。調整之後,基準線升級為Core i9-9900K,這個很正常,但是單核心比重提
高至40%,四核心略微降至58%,而多核心僅僅佔2%。

此無疑與現今的大趨勢截然相反,因為不單是AMD,Intel亦在不斷增加核心數,桌上型主
流平台接下來極有可能增加至10核心。
UserBenchmark解釋說,如此調整是對成千上萬次測試進行分析後作出的,是對典型遊戲
效能的最好反映,因為遊戲效能在多核心上提升並不好,更多核心只適用於伺服器及工作
站應用。
調整之後結果如何呢?舉一個例子,4核心4執行緒、4.0GHz的Core i3-8350K綜合成績為
83.5%;8核心16執行緒、3.7GHz的Ryzen 7 2700X綜合成績為81.7%。核心數量少但時脈更
高的入門型號,贏過了對手核心數量多但時脈略低的旗艦型號。另外,調整前Ryzen 9
3900X領先Core i9-9900K 1-3%,調整後落後了5%。

調整後的遊戲CPU前20強:
