: 他之前在 Intel 參與 Pentium3 到 core i 的設計,目前已離職
: 投影片中提到幾件事:
: * 現在 Intel 失去了專注,沒在消費者/server端推出適合的產品
: * 併購來的團隊都沒用
: * 在筆電CPU 加上 AVX512 只是浪費空間,沒多少筆電用戶會用到
: * 塞了一堆無用又耗電的功能, 所以 core 數量輸給 ARM/AMD
: * Skylake 架構專注在單一核心效能, Ryzen 則是靠 SMT 提高 CPU 區塊使用率
: (大概 13:00~22:00 談架構設計,要有點專業才能懂orz)
: * 現在 Intel 能維持佔有率只是運氣好,AMD 沒有能力吃下更多市場
: * 世界已經變了,不再是同一套架構打天下的時代,沒有那麼多人需要 SIMD
: 那些空間客製化更多 core 才對
: * 重金請來有MBA的管理者沒用
: * 對外公關該談更多技術,別學 Apple
說實在話
我覺得最近一堆講牙膏OOXXOOXX的
前員工543
這些都馬後炮
同樣的東西在amd 2014 2015甚至2016也一堆人講
而且amd更慘
尤其是ibm幫
前ceo Rory Read
蘇媽
紙大師
前ceo RR ->併購seamicro 遠不如預期
蘇媽->kaveri currizo之間搖擺不定 project一變再變
紙大師->幹話天王
x86市場沒那摸複雜
而且以牙膏的$$
塞滿混吃等死的人也不會怎樣
實際上
不管是amd還是牙膏
x86市場說穿惹一句話
製程&架構 得一可安天下
當年amd可以起死回生
就是28nm推土機->14nm zen
製程跟架構都大躍進
當今牙膏一臉屎樣
實質問題就是10nm
從表定2016拖到今天也只有筆電小量
10nm delay造成布局跟計劃一團混亂
至於轉單GG
這也不用想太多
對GG而言
完全勝利條件是
1.全吃x86
2.牙膏分拆fab->若干年後該fab放棄先進製程研發 如GF
這是牙膏完全沒辦法接受der
所以兩邊合作也只是各懷鬼胎
簡單來講
牙膏要止血
只有新製程能按時量產能救
說到牙膏不務正業的幻想
幾年前牙膏洋洋灑灑地寫惹一堆進軍自駕車
現在想想
感覺
自駕車
要變成
牙控車惹
