First of all I would like to say that Intel improved the performance of its dual-core solution quite significantly. Thanks to the finer 65nm production technology, Intel increased the clock frequency of its new CPU and equipped it with the larger L2 cache. As a result, Pentium Extreme Edition 955 is not an eternal loser in the dual-core duel anymore. There are a lot of applications where Pentium Extreme Edition 955 managed to defeat AMD Athlon 64 X2 4800+, the top dual-core solution from Intel’s competitor. In fact, AMD processor remains the leader only in gaming applications, in professional OpenGL tasks and a few codecs.

唔係有FX-60, AMD既K8神話就

溝通快 =/= 快

始終freq快咁多

(3.46GHz vs 2.4GHz)

2.4GHz 對 P4 來講好快

同埋好似Intel個dual core efficiency高左

之前我話 Presler 好似會比 Smithfield 溝通得快 d, 因為 Presler 改左唔用 FSB 溝通

當然後面係錯

不過前面都岩

多左FSB嘛......

你睇真d, 係4.26G先可以同4800+打個平手 or 唔計3D多一兩個 task 勁過4800+
3.46G唔超一樣慢過4800+, 個conclusion 食*大

都唔算既

仲有Encoding

Pentium XE 都係解決唔到佢會慢過 P D 的情況...

Presler 同 Cedar Mill 用番 20 層 Pipeline Stage 你話幾好

一定超快

Northwood咁既Pipeline加Prescott既Prediction branch......

唔知行唔行得返3.XXG呢?

唔關FSB事.
而係每Cycle都要做野,熱咪又多D囉.

而家每Cycle未必要做野.
