Article : P4 6xx & P4 EE 3.73 GHz
 

Probably wearied to see AMD nibbling shares of market and perhaps also upset to have to give up the race at the frequency, INTEL promises for 2005 an avalanche of functionalities intended to sit its notoriety and to take again the leadership in terms of performances. The first of these new processors to be born officially are Pentium 4 of series 6, which quickly will succeed current series 5.

Equipped with 2 Mo of L2 mask and instructions EM64T, these new processors will also support technology EIST. Announced at frequencies ranging between 3.0 (630) and 3.6 GHz (660), Pentium 4 series 6 will be accompanied by the traditional development, Pentium 4 EE 3.73 GHz (720). We thus will see whether the practical profits of performances brought by this refresh of the core Prescott are worth displacement. With this intention, we will test Pentium 4 630 (most economic) and Pentium 4 EE 720 (expensive) that we will compare with the old range of INTEL, P4 5xx, but also with Athlon 64 of AMD. We will also benefit from it to give a progress report on the new functionalities brought and the new architecture of the mask. Of course, we will also show some tests of overclocking in order to the capacities of this new core in this field. With the program, much of surprised...

新的P4EE變成只有L2 2MB快取
跟之前的P4EE比較起來反而少了512KB的快取
這樣效能會好嗎？
具有L3快取的 P4EE將成絕響？

應該是因為L3快取的效率本來就不如L2的關係吧？
所以乾脆把L2加大就好了，
但這樣一來P4EE和P4 6XX只剩FSB多了266的差別，
那麼小的差距，買P4EE的人大概是錢太多沒處花… :p

另外P4EE的效能看起來只有K8 3800+的水準（除了視訊編碼外），
難怪今年AMD放慢了時脈的進展，
當年K7 vs P3的時脈大戰已不復見了…

照泥的說法~~k8是神之cpu囉 :laugh: :laugh:

不是放慢...是跟P4比起來, K8的架構本來時脈就不可能直接追上
這個應該是老話題了吧?

其實小弟覺得還好耶...當初Thunderbird VS Coppermine的最終結果是
Coppermine 停在 1.00G, 然後Thunderbird在1.2G"等"
Intel也直到Northwood上市才跟上效能腳步,然後P4C上市才在取得效能王座
老實說從2000~2005年...效能王座是Intel的時間不長耶
只是這一次比coppermine那次還糟...
因為coppermine至少比Thunderbird功耗較低,而440BX/i815也遠比KT133穩定
但是Prescott比Winchester功耗整整大了三倍,i915/925也推的很不順...
所以可能要2006年後看看Parrot/Merom這些新架構還有沒有機會吧...
Prescott和其雙核Smithfield看來是玩不下去了...
