會問這種問題的可能是不瞭解電腦的歷史
386那年代為了表示相容性,各家都用類似的CPU命名原則
intel : 80386-DX/80386-DL/80386-SX/80386-SL
AMD: Am386SXLV/Am386DXLV
IBM: 386SLC(Intel代工)
為什麼從這開始講,是因為Intel在286以前,IBM跟Intel簽約時協定寫說要兩個製造廠
,所以同時有AMD跟Intel在生產IBM相容的CPU,到了386時代Intel撤回這個協定,拒絕
透露386詳細訊息(是的,intel 開始表隊友是很早就開始的事情),此時Intel可以不
必照IMB規格製造CPU。由於毀約AMD告上法庭,所以AMD能繼續發行386CPU,但是埋下日
後CPU戰爭的種子.....
到了486長這個樣子:
Intel : 80486SX/ 80486DX/ 80486DX2/ 80486SX2/ 80486SL / 80486SL-NM /
Intel 80487
IBM: IBM 386SLC/ IBM 486SLC2
德州儀器: TI 486DX4
Cyrix: Cx486
AMD: AM486/ 後來搞了個Am5x86
聯電: UMC Green CPU 486
But, 就是這個But
Intel在別家(臺灣的)出486並且其本身改出較強的性能時,Intel開始跟他們打官司,
AMD則是這時打算開始研發自己的版本,省去逆向工程的麻煩
被打官司的那個就是聯電,害得聯電不能賣CPU,更讓AMD確定了自己設計製造的決定是
對的
所以其實會有今天這局面,還不是Intel自己幹的好事,怪不能怪別人呀
那時就是各家CPU都做了類似的名稱,沒什麼好意外的,
到了後來AMD跟Intel還會互抄指令集,
一開始Intel搞了MMX指令集在奔騰上(但因為設計原因,需要用到x87輔助處理器,效能
性能都不實用),AMD跟進發佈了更強大的3D Now!指令集,後來發佈Extended 3DNow!
,算當年不錯而且實用的指令集,所以Intel後來搞了個SSE指令集,說是實現所有3D n
ow指令集功能,支援IEEE754的浮點數規範(也就是說Intel在自己家造輪子,造完改了
個名字叫車輪)
所以本來就是抄來抄去的東西,不光是名稱互相搶,連指令集功能也互相搶來較勁,真
的不要大驚小怪
對了,一個題外話
有人以為intel 搞得sse系列指令集AMD一開始不支援很差勁,殊不知這是Intel抄人家的
功能....
※ 引述《ray90910 (Don' look back in anger)》之銘言
: 如題
: Intel的B250--->AMD搶B350
: 讓intel只好改成B360
: 還有
: Intel的X299--->AMD搶X399
: NVIDIA的GTX1080、Rtx 2080
: --->AMD搶RX3080
其實名稱很好認
消費級主機板Intel的晶片不會帶X,改帶Z
我猜可能是避免強碰X360(誤)
Intel有H,AMD沒有H
簡單說,AMD的CPU對H的主機板是不行的
要到工作站等級才會都有X
然後AMD的只有B跟X兩個
Intel才是搞複雜的那位,弄了B啦H啦Z之外,還搞了Q這種的晶片
顯卡部分,目前AMD就Rx開頭就對了
: 明明自己以前有自己規則像是a68,78,88
: 還是RX4x0,5x0
: 就要突然大改搶人家接下來的命名
: 這樣會不會滿沒品的?
沒品的是誰自己想一想
: 還是3C界常常這樣做?
毀約還靠專利官司不准人家賣CPU
