怎麼還有人對AMD抱持希望
intel 2017 10nm 那時AMD才剛進14nm沒多久
看看intel的第8代繪圖核心有多強，intel 15W就有AMD APU 95W的6成效能，這還只是GT2等級而已
你是用現在的APU kaveri 來比例

Carrizo首先会应用于笔记本、Windows平板等产品中，TDP功耗有15W、35W等多个级别，桌面分支的Carrizo则会有45W、65W等产品。(桌面版尚未知)

若推出BGA版的Carrizo桌面處理器 簡單來說 就是變相的 低功耗 10W~35W Kaveri的桌面版
並不是原先規劃的Carrizo的45W、65W桌電版 比前代Kaveri桌電版 沒有提升的意思
但要注意一點 Carrizo是 業界首款HSA1.0的產品
最近國外的文章測試

MD Carrizo graphics to double perf of compared to Kaveri?
There are some leaked SiSoft Sandra benchmark results of AMD's Carrizo APU in their online database, the new chip is mostly aiamed at the notebooks segment, but it seems it will provide a big boost in integrated graphics performance. If the SiSoft data is accurate, Carrizo is about twice as fast as Kaveri and three times faster than Intel's Iris Pro. Carrizo scores 606.64Mpix/s in the SiSoft Sandra GP (GPU/CPU/APU) Processing test, a level that can be compared with the Radeon R7 265, a card that offers roughly the same graphics performance as the chip inside the PlayStation 4. An A10 7850K scores around 270 Mpix/s while Intel’s HD5200 Iris Pro scores a more modest 200 Mpix/s. The new mobile APU will be manufactured with the same 28nm process as Kaveri, with power consumption up to 35W for the Carrizo down to a maximum of 15W for the ultra-mobile Carrizo-L parts.
SiSoft洩漏了AMD 新的Carrizo APU 的成績
在GPU的方面，採用GCN1.2 的Carrizo APU有512sp
測試分數大概是 Kaveri 的2倍，Intel Iris Pro的3倍
Carrizo: 606.64 Mpix/s
Kaveri(A10 7850K ): 270 Mpix/s
HD 5200 Iris Pro: 200 Mpix/s
這樣的成績大概可以R7 265 同等級 (R7 265 是 1024 sp)

根據3D Mark Fire Strike測試，A10 7850K大概是1400分
假設Carrizo成績為真，估算3D Mark Fire Strike
Carrizo/Kaveri = (606.64/270)x1400 = 3145分
桌面板的 R7 265(獨顯HD7850) 是 4700
很符合筆電的Carrizo APU 是相當於桌面板的 R7 250(HD7770 HD6850)
國外網站是寫 約獨顯7850效能 不管是高估還是低估 先暫時以低估的的角度去思考
注意喔 Carrizo還是28nm舊制程 intel的第8代繪圖核心是14nm
Carrizo APU 筆電15~35W就有 7770獨顯的效能
Carrizo APU 若是用在桌電95W的話會是多少?如果是運用在14nm的話?
到現在還有很多玩家以為奈米數越高是越好的錯誤觀念
奈米數越低是越先進製程 也是性能發揮高效能的關鍵性(先進製程成本會反應在高價格上)
