Intel 第八代處理器 Coffee Lake 因為受到 AMD 壓力的關係,這次牙膏擠比較大力,除了主流級 Core i7 迎來了首款6核心12執行緒之外,Core i5、i3 系列也都直接升了一級,i5 從4核心變成了6核心,i3 也從2核心4執行緒變成了真4核心,買七代的玩家應該會有點不是滋味,不過目前比較平衡的是要吃第八代就只有 Z370 晶片組主機板可選,主板價格相對就高了一些,尤其是如果你要配 Core i3 的話。
目前第八代 Core i3 系列就只有一顆 Core i3-8100,4核心4執行緒,時脈3.6GHz,L3快取6MB,TDP 功耗為65W,國外預定售價為117美元,台灣代理商盒裝價為4250元,國外也是偏高於預定售價,因為最近貨並不多,不過這價格還是遠低於同樣是4C4T的第七代 Core i5 就是。
Core i3-8100 盒裝,右下角很諷刺的是與第六、七代同為 LGA1151 但板子卻不能共用,這一切應該都是利益優化考量,畢竟如果能通用,Z370 應該沒太多人會考慮。

外盒側邊有一鏤空設計,主要是不用拆封就可以讓買家確定有CPU在裡面,且可以清楚看到型號。

配件有散熱器、說明書。

原廠散熱器,這大概好幾年都長這樣了,底部有散熱膏。

Core i3-8100,核心時脈3.6GHz,不支援 Turbo Boost 技術。


測試直接拿 Core i3-8100 來PK對手 AMD Ryzen 3 1300X,這兩顆規格與價格相近,1300X 代理商貨與 i3-8100 相比便宜50元,不過若買水貨還能在俗個300元。測試平台如下,記憶體因為相容性的關係是不同組,雖然同為 DDR4 3200MHz,但時序上有點差異,這部分可以看截圖。

效能差異比較
整理一下上面的數據,這樣應該就很清楚了。

小結
以預設來看,Intel Core i3-8100 的效能大致上可以小贏 Ryzen 3 1300X 沒問題,不過 1300X 是不鎖倍頻,在超頻4GHz之後多核心效能大約可以提升11%左右,反倒在大部分的項目是可以贏過 i3-8100。
雖然說第八代 Intel Core i3 升級了真四核,對比上一代 Core i5 四核價格是划算的,但在主板上目前也只能配高檔的 Z370,主板就得占掉約4000元左右的預算,以入門級組裝來說這比例算是有點高,當然 AMD Ryzen 3 就沒這問題,可以搭較便宜的 B350,甚至不超頻或需求少也有更陽春的 A320,主機板大概在2~3000元之間,對於入門玩家而言是比較有選擇彈性。
目前第八代 Core i3 系列就只有一顆 Core i3-8100,4核心4執行緒,時脈3.6GHz,L3快取6MB,TDP 功耗為65W,國外預定售價為117美元,台灣代理商盒裝價為4250元,國外也是偏高於預定售價,因為最近貨並不多,不過這價格還是遠低於同樣是4C4T的第七代 Core i5 就是。
