40% IPC over Core Arch...

Going to say goodbye to AMD

我粒CZ唔通咁快就成為絕響?

其實而家 AMD 都出唔到勁 U, intel 洗乜出 d 咁勁既野黎打自已既 product ? 出多 d e8 之類既野都好賺啦

Unless Bulldozer did gd, AMD CPU may become history

呢D野應該之前準備好晒 , 按照Project去做 ...
同埋話晒AMD而家有ATi , 慢o左手既話唔知AMD會搞咩出來

Intel Low-end又有 Atom 食 UMPC ( 要同 VIA-nVIDIA / AMD Geode 爭)
Desktop Line 又有 Core 2 (Wolfdale / Nehalem ) 打到 AMD 幾乎完敗 ( 除左價格 , 暫時)
Server 既話 Nehalem  放棄埋 FSB + 咁鬼多 Channel + IPC 強勁 , K10 => K10.5 有無 30% improvement 都成問題

唔怪得 AMD 今年 Computex 咁落力賣廣告 promote
無人買佢d 產品 真係

nV+ VIA (吳) + AMD-ATI (蜀) Vs Intel (魏)
依家個勢最唔惦正是 AMD

CPU除非AA Bulldozer/K10 45nm + 6Core 做一場好戲，否則難打，頂多打C/P + Platform advantage……
ATOM vs NANO vs Fusion @ Nettop--> 當ATOM DC推出後，除非Nano趕得及出dual-core版，否則Intel短期內會食住VIA。前提是Intel到底何時才開放PCI-E X16支援以阻止Graphic支援部份上的損失。
ATOM vs NANO @ITX --> 在重視成本的ITX mkt上ATOM唔會有太大優勢…

GPU方面AA面對GTX280都不會太難睇。

Intel CPU+AMD GPU => nVidia............
我覺得,而家Intel係想出粒CPU KO到NV個GPU效能(Flops),等NV無得聲.

短暫時間來講無咩可能追到個Flops , 另外 nVidia 都無可能咁白痴企起度等比人追
而且家陣又同VIA合作 ...



基本上戰況七國咁亂 , 好多未知因素難以定斷

目前有d似係多家和AA有關的company + AA VS Intel

P.S AA internal spoiler did gd agen, last time he spoiled the plan of X2

但最大問題係之前AA食唔到物理加速呀 ...

家陣nV一個CUDA都玩得死人

fsb detect is wrong, and it\'s not FSB
無記錯的話Conroe 2.3Ghz vs Nehalem 2.3Ghz Pi下，Nehalem快dd…

QuickPath ...

計數果方面好似無乜點大改 ... Pi 唔會有咩進步我都明既
但其他方面

AMD 今次大劑
唔怪得拿拿聲 Cancel Phenom FX  / Phenom x2 ..

佢拿到出來先算啦
我睇Wiki見到Server版有Quad Channel

(好似唔係新野 .... 係咪我小見多怪)
