HT真的有增進多工效能嗎?未必..(P4 3.0E測試)

討論區的良好風氣是靠大家維持的 ( 讓在下想到當初在小白天堂受氣的經驗... :lkl: ) ! 在下
是認為 Sander 大的講解著實讓在下上了一課 . 也真的弄懂 HT 的深意所在 , HT 嚴格來講不算
是很新的技術 . 但是妥善利用的話可以增進不小效能 , 但可惜的是 Intel 並沒有很大力的推廣 ,
可能 Intel 自己也有自知之明 ! 知道 HT 的罩門在哪 , 所以才會努力生出 HT2 吧 ? 不管如何 ,
有競爭就有進步 -- 不管是大還是小 ! 都是進步 , Intel 深知消費者心理在想什麼 , 廣告行銷包
裝的手法真的是 AMD 比不上的 ! 這一點 AMD 應該也要加點油 , 提高良率增進市佔率 ! 就像是
nVIDIA 和 ATI 一樣 , 沒有競爭消費者怎麼可能買的到便宜又大碗的產品呢 ?
PS : 話說回來剛剛還在找這篇討論主題發現怎麼突然不見了 , 原來是狂大置頂說 . 這篇討論主
題最大它睎雩茯O Sander 大吧 ? 詳細的解說讓版上的玩家改變對 Intel 的印象 , 也讓在
下能更深入了解這些技術的深層面 ! 學到了一些很棒的程式設計基本概念 .... YYY

leakage current...
Good point!!
Leakage current is the current that flows through the protective ground conductor to ground. In the absence of a grounding connection, it is the current that could flow from any conductive part or the surface of non-conductive parts to ground if a conductive path was available (such as a human body). There are always extraneous currents flowing in the safety ground conductor.
Why is that important?
Electrical equipment commonly includes a grounding system to provide protection against a shock hazard if there is an insulation failure. The grounding system usually consists of a grounding conductor that bonds the equipment to the service ground (earth). If there is a catastrophic failure of the insulation between the hot (power) line and touchable conductive parts, the voltage is shunted to ground. The resulting current flow will cause a fuse to blow or open a circuit breaker; preventing a shock hazard. Obviously, a possible shock hazard exists if the grounding connection is interrupted, either intentionally or accidentally. The shock hazard may be greater than supposed because of the leakage currents. Even if there is no insulation failure, interruption of the leakage currents flowing through the ground conductor could pose a shock hazard to someone touching the ungrounded equipment and ground (or other grounded equipment) at the same time. This possibility is of much more concern in medical applications, where a patient may be the recipient of the shock. A fatal shock could result if the patient is in a weakened condition or unconscious, or if the leakage current is applied to internal organs through patient contacts. The double insulation provided in non-grounded equipment provides protection by using two separate layers of insulation. The protection in this case is ensured because both layers of insulation are unlikely to fail. However, the conditions that produce leakage currents are still present, and must be considered.
What cause leakage current?
There are two types of leakage current: ac leakage and dc leakage.
Dc leakage current usually applies only to end-product equipment, not to power supplies. Ac leakage current is caused by a parallel combination of capacitance and dc resistance between a voltage source (ac line) and the grounded conductive parts of the equipment. The leakage caused by the dc resistance usually is insignificant compared to the ac impedance of various parallel capacitances. The capacitance may be intentional (such as in EMI filter capacitors) or unintentional. Some examples of unintentional capacitances are spacings on printed wiring boards, insulations between semiconductors and grounded heatsinks, and the primary-to-secondary capacitance of isolating transformers within the power supply.
這個討論區真的不錯
唯一美中不足的是，還是充滿了對INTEL有極度恨意的網友
一堆人只要一提到INTEL的產品，就一昧的漫罵和幹瞧，已經失去討論的意義
在台灣網路上大多數的硬體站台，都已經被那種極度恨INTEL的網友給佔據，不知道大家同不同意？
希望站大能夠注意一下這種情況，不要讓這邊也讓那些充滿恨意的網友給佔據。
不常發言，只是提供個人建議。
也希望這個討論區能夠越來越好。 [/b][/quote]
這篇討論串超優！
連狂兄都來推了！
不過，對於兄台的說法，
我到比較保留，
整篇看完，不覺得有啥偏激的言語啊？
又怎會扯上「恨」這個字眼？ :(
兄台似乎太過言重！
況且，各人喜好，隨意就好，
我不喜歡INTEL，你也可以不喜歡AMD∼
但是至少在這篇，看不到誰很用力的罵INTEL∼ :)
AMD證明了一件事情.高頻率不等於高效率，在很多大型電腦上的設計慢慢導入PC後，產生了很多不一樣的思維.這是好事....
Intel的產品其實從筆記型的P-M就看的出來他們開始不在頻率這個題目上作文章了.
