SmeiAccurate從多個消息渠道獲得確認，AMD已經突然取消了採用28nm工藝的下一代入門級低功耗APU Krishna/Wichita。
它們原本計劃用來取代現有的40nm Ontario/Zacate APU核心及其Brazos平台，但不知為何突然被砍掉。具體原因尚不清楚，但普遍懷疑是GlobalFoundries 28nm SHP代工工藝進展緩慢的緣故。根據路線圖，該工藝要到2012年年中才能投入量產，也就是說直到明年第三季度才能批量供貨。即使Krishna/Wichita拖延到屆時再發布，也要等到明年年底才能形成市場規模，而根據路線圖，2013年就會有再下一代的新平台了，Krishna/Wichita的生命週期就會非常短。
Ontario/Zacate是台積電代工的，Krishna/Wichita最初也說是台積電獨享，後來又說台積電、GF兩家分工負責，但不管選擇誰，代工廠問題肯定再一次傷透了AMD的心。
不過考慮到AMD現在對移動領域的高度重視，也不排除是從戰略上取消的可能性，那樣AMD可以加速提前推出更新、更強的Kerala平台和Kabini APU。但願如此。
不管那樣，Brazos平台都要繼續Hold下去了。
SemiAccurate has been hearing that the rumors that AMD’s (NYSE:AMD) Witchita and Krishna are on the chopping block for a few weeks. Over the last few days, that has been confirmed by several different sources.Yes, you read that right, the follow on to Brazos/Ontario/Zacate has been knifed, there will be no 28nm Wichita and Krishna. Why? No one is saying definitively, but we would guess that it is due to timing of GloFo’s 28nm SHP process.As you can see from the picture below, taken from a GTC 2011 slide, the process is set for production in mid-2012. That means there won’t be significant volumes until Q3/2012 for a chip that is due to be replaced at the end of 2012.
AMD產品路線圖
看來不僅僅是AMD本身開發問題，連它的代工廠都不支持;em42; 真的是要加油啊...
外傳是因為GF開發28nmAPU太慢...，會卡到下一個世代產品，所以毅然決然的終止28nmAPU
真的很可惜!不過也希望AMD提前推出2013年代號為 Kabini的 APU囉!!!;em03;
