AMD的雙核心性能果然夠悍
P-D&p-EE幾乎完全被打趴
包括影音編碼,3D rendering等強項幾乎全輸光了
連sysmark2004也輸
只能贏神奇的'sandra'@@

必v消耗測試
雙核心的opteron 175(2.2g)竟比單核心P4 660還省電@@

AnandTech裡面的Multitasking Scenario可以看出雙核優勢,以Doom3為例:
Single:(AnandTech Page18)

Multi:(AnandTech Page26)

可以看出單核慘兮兮~
拖垮45%~60%
Pentium D雙核雙線損失13%~22%
Pentium XE雙核四線損失7%~18%(HT還是有一點用啦,少虧4% mooon )
Dual Core K8性能損失至多7%
(以此兩個有對比測試的遊戲而言)
所以一邊剋Game一邊用小毛驢運貨一邊聽音樂一邊當Server
應該是輕而易舉的事 ;lik;

另外一家的測試,個人對於電源消耗頗感興趣:(The Tech Report Page16)

該說是Xeon的電源管理很棒呢?
還是說K8的核心運作很涼?

馬克大真的是這樣嗎? mooon
有好超批號出來的話
一定又會再下毒手,橫掃千店 :sun:

個人預計s939系列最多出到2.6G~2.8G為止...
之後2006就看Socket M2+DDR2了...唉... :QQQ:

p4的唯一優點==>多工
好像在雙核心也蕩然無存
看來該大舉進攻k8了 :fi: :fi: :fi:

:sun: DDR2沒什麼不好的呀！06年，ddr2 -667 800成為主流，不會比現在的ddr400差的。 ;ya;

這樣很傷本... :PPP:
有DDRII800-4-4-4-12@1.8V這樣的標準規格再下手 :fl:

DDR2的確仍未成熟~
好像也沒比DDR好多少!

但Mydriver竟然說AMD可能直接跳過支援DDR2,用DDR3...
我覺得可能是有,但不高~
必竟DDR也是 Intel及各家在推動!
才成主流
DDR3要靠AMD去推動,有點難度!

儘管網站寫得天花亂墜,
一般玩家也買不起這個等級的電腦吧...

沒錯啊...
一般人當然不會新品剛推出就購買
等一段時間
降價至C/P合理的產品再入手
相信是多數人的思維

不過這些都是很好的指標性測試
讓人知道自己需要的是什麼...
所以這些測試拿來參考用仍是非常有價值的
要怎麼取捨,就要看觀者的心態如何

引用AnandTech的一段話:(Page 4)

Because Intel is only shipping lower clocked dual core CPUs, Intel's chip prices are much lower - not to mention that Intel's manufacturing abilities far exceed those of AMD. Percentage-wise, the Pentium D 3.2 commands a high premium for that second core, but the prices are overall quite reasonable. The fastest Pentium D is still cheaper than the slowest Athlon 64 X2 4200+, and the slowest Pentium D is ridiculously cheap compared to AMD's dual core offerings.

AMD's answer to Intel's aggressive pricing is two-fold. Eventually, all of AMD's CPUs will be dual core, and thus, prices will be driven back down to single core levels. But for now, AMD feels confident enough that their single core CPUs are fast enough to compete with Intel's low clocked Pentium Ds. We put that exact thinking to the test in Part II of our Intel dual core preview and concluded that it really depends on what type of a user you are. If you tend to multitask a lot or run a lot of multithreaded applications, then a slower Intel dual core is what you need; otherwise, a faster single core AMD is your best bet.

看每個人的時間跟需求囉...
