※ 引述《nk11208z (小魯)》之銘言
: 網路上找了許多文章,還是不太了解HT跟SMT的實際差異
: HT我知道是英特爾用虛擬化的方式將CPU模擬多線程
: SMT看起來也是差不多
: 那實際差異是如何阿?
: 好像SMT對於多核的遊戲最佳化好像比較好,HT對於多核遊戲好像沒那麼好
這點我要說一下
蠟是當年AMD的CMT才沒這麼好
實際上也不是差到哪去,
是當年遊戲廠商跟軟體廠商根本沒對多核心優化
多數的廠商都是以Intel為主要系統做開發跟測試,
喔,下個月軟體要上市了,但是評測項目根本沒測完甚至某些功能還有重大Bug怎辦?
先修Bug再說
等到下個月:
誒,後天要上市新的版本,我們研發才剛修好軟體,別說QC了,QA都還沒檢驗過怎辦?
大主管:喔,那就QA這邊能動就好,QC這邊測項先測不能靠Patch修正的功能
研發主管:喔對了還有個問題,我們對其它平台的支援度...還沒去優化過
PM主管:你要想辦法阿,下面客戶都急著要新產品了誒
大主管:好了好了,你們就直接用一個平台先測過再說
上面還是好的,
大部分公司哪有資源生第二套測試環境出來
也根本沒有什麼QA跟QC的分別...
然後各位可以看一下PUBG跟Overwatch什麼時候宣布支援六核心平台,
(壓路機:Am I joke to you?)
除了CMT的失敗之外,AMD還做錯一件事:投資資源在超頻上
他們哪會知道版友嘴上都愛超頻,結果實際上還是這麼在意電源跟功耗
我常在看現在的人討論Intel怎麼全核5.0 5.1、AMD怎麼全核4.3 4.4 4.5
不好意思,八年前九年前,8350就能上8
甚至有人能到12(但是一點都不穩)
: 我猜英特爾的多核無用論是用自家的HT去作測試後得出的結論吧?
其實還是風光過,當年X4 640那年代還是瘋迷過一陣子
