超頻Intel處理器

Q:何時一台配備 3.4 GHz Intel® Core™ 處理器的 PC 比另一台也配備 3.4 GHz Intel Core™ 處理器的 PC 更快?答:當您對處理器進行超頻時,它會以高於額定 3.4 GHz 的速度運作。

超頻感到困惑?別這樣。在流行的Intel酷睿處理器系列中有一個特定的子集是專門為超頻而設計的。給定的 CPU 的運行速度可以比其公佈的基本頻率快 0.1 GHz、0.2 GHz,甚至可能快 1.0 GHz。無論是藉助軟體實用程式還是透過系統 BIOS 編輯關鍵設置,這都相對容易做到。

超頻主要是希望從筆記型電腦桌上型電腦獲得最大性能的高級用戶的領域。然而任何人都可以做到。只需確保您了解超頻的相對好處和風險:

  • 超頻專家:超頻處理器每秒可以完成更多操作,加速從啟動到保存檔案的所有操作。它還可以縮短程式回應時間,這對於工程師、影片編輯和 PC 遊戲玩家等高要求用戶來說是一個福音。
  • 超頻缺點:超頻處理器需要大量電量,因此您將使用更多電量(筆記型電腦用戶的電池壽命將縮短)。它還在較高溫度下運行,產生的熱量可能會影響系統冷卻能力,並可能損壞處理器或縮短其使用壽命。

因此,超頻是一把雙面刃。沒什麼好害怕的——畢竟Intel生產的 CPU 是為允許超頻而設計的。該公司甚至發布了一個軟體實用程式來幫助完成該過程。但也有缺點,這就是為什麼Intel總是在其超頻相關文獻中包含警告。例如“改變時脈頻率或電壓可能會損壞處理器和其他系統組件或縮短其使用壽命”,以及“如果處理器超出其規格運行,則產品保固可能不適用。”

什麼是超頻?

超頻是一種自訂調整 PC 處理器(有時會調整 RAM 等其他組件)的方法,使其運行速度比製造商系統規格中承諾的速度更快。 CPU 的額定運作頻率可能為 3.4 GHz,但超頻可使其運作在 4.0 GHz 或更高頻率。

三種特定的內部設定通常是超頻的一部分:處理器的基本時脈速度(適用於所有核心)、「核心倍頻」(每個核心都有一個倍頻)和核心電壓(處理器運行時使用的電量)。最簡單的是,超頻涉及增加核心倍頻以超過每個核心的基本速度。

例如,3.4 GHz 處理器的基本時脈速度可能為 100 MHz,標準核心倍頻設定為 34 (100 MHz x 34 = 3.4 GHz)。如果將乘數加 1,CPU 將以 3.5 GHz 運作。或者您可以嘗試將它們增加 6 以達到 4.0 GHz。 [請記住,這是一個簡化的解釋。

PC 超頻的缺點是什麼?以高於額定速度運行處理器可能需要更多功率(即增加電壓設定)。對於筆記型電腦用戶來說,這意味著電池電量的使用時間更短。更重要的是,較高的電壓有時會導致處理器等電氣組件停止運行,或縮短其預期壽命。另外,更高的電壓意味著產生更多的熱量,而熱量是許多內部 PC 組件的敵人,而不僅僅是處理器。

如您所見,超頻是一種妥協。您的電腦運行速度更快,因此您可以做更多事情。大多數程式和操作的反應速度更快,因此等待時間更少。但如果你不小心的話,你的系統可能會崩潰。如果您長時間超頻,您的處理器可能不會像其他情況下那樣持續很長時間。

如何確定您的 Intel CPU 是否可以超頻

即使您了解超頻、倍頻器等所有知識,但了解並非所有Intel酷睿處理器都可以超頻也很重要。事實上,在大多數 Core CPU 上,乘數無法更改 - 它們被鎖定在標準數字。

因此,對Intel處理器進行超頻的關鍵是它在製造時必須「解鎖」。幸運的是,截至2020 年末,可以輕鬆識別未鎖頻的Intel處理器:其SKU 以K 或X 結尾,例如桌上型電腦的i5-10500K 或i9-10920X,或筆記型電腦的i9-10980HK(Intel筆記型電腦CPU 中的H) SKU 的意思是「高效能」)。

超頻還需要其他硬件,例如特定的主機板、高端冷卻功能等。但這種擔憂主要影響那些從頭開始組裝自己的電腦的人。對於Lenovo等公司的預製筆記型電腦或桌上型電腦,只要處理器 SKU 顯示已解鎖,您就會知道關鍵的相關組件也將支援超頻。 [但請記住這些限制。沒有系統可以無限超頻。

超頻與Intel睿頻加速相同嗎?

是和不是。超頻與使用Intel® Turbo Boost 類似,這兩個選項都會暫時增加處理器的時脈倍頻,以推動其以更高的速度運作。但睿頻加速是許多Intel酷睿處理器的內建自動化功能。相較之下,超頻是使用者手動或在軟體實用程式的幫助下完成的操作,並且只能在時鐘倍頻器為此目的解鎖的處理器上完成。

Turbo Boost 本質上是按公式超頻(Intel稱之為「演算法超頻」)。每個支援 Turbo Boost 的 CPU 都有一個預設的“升壓時脈”,用於確定可以推動的速度(以及持續時間)。選定 CPU 核心的速度會根據兩個因素自動提高或恢復正常:

  • 對更好效能的需求:Turbo Boost 在感知到需要時被激活,例如當用戶運行高端渲染軟體、玩資源密集型視訊遊戲等時。
  • 可接受的系統運作條件:Turbo Boost 檢查內部溫度、電壓和其他關鍵項目,以確保 PC 能夠處理對 CPU 提出的更高要求。

潛在的 Turbo Boost 速度通常列在新筆記型電腦或桌上型電腦的處理器規格中。速度經過預先測試,因此在使用 Turbo Boost 時通常無需擔心系統崩潰或其他意外事件。相比之下,用戶可以嘗試實現的超頻速度幾乎沒有限制 - 只要他們了解太高的設定可能會導致 PC 崩潰、損壞活動項目或資料等。

如何超頻Intel處理器

使用者超頻Intel酷睿處理器有兩種常見方法。他們透過系統 BIOS 更改各種設定(然後測試結果)來手動完成此操作。或者,以更簡單的方法,他們使用軟體實用程式來管理更改,甚至可以幫助他們在系統超頻時監控關鍵元件。

讓我們更詳細地回顧這兩種超頻方法。

使用系統 BIOS 超頻

BIOS(基本輸入/輸出系統)是運行主機板並與連接到主機板的各種組件(包括處理器)進行通訊的軟體。您可以使用 BIOS 更改 CPU 時脈倍頻器和其他關鍵設定 - 從而實現對超頻過程的良好控制。但這只能由相對專業的 PC 使用者來完成;在錯誤的時間更改錯誤的設定可能會導致大問題。

我們不會在這裡給出詳細的 BIOS 超頻說明。可以這麼說,一般來說,它涉及更改倍頻(也稱為 CPU 核心比率)、核心電壓、高速緩存/環比率和高速緩存/環電壓等設定。更改設定後,您需要根據標準效能測量來測試超頻系統,並可能重複這些步驟,直到您找到系統可以支援的您喜歡的速度。

使用 Intel Extreme Tuning Utility 超頻

Intel® Extreme Tuning Utility (XTU) 可以為您簡化和管理超頻流程。它對於任何想要嘗試以高於額定速度運行處理器的人來說都是有幫助的,對於那些不太習慣透過 BIOS 編輯設定的用戶來說尤其有價值。

Intel XTU 可下載,並將多個超頻相關任務組合在一個應用程式中。它識別並監控所涉及的硬體。它有助於調整時鐘倍頻器和其他關鍵設定。它測試系統穩定性(當您以高於額定速度運行時很重要)。它甚至可以幫助用戶在超頻時對系統效能進行基準測試。

那麼,您準備好透過超頻探索更快的 CPU 速度了嗎?一種方法是建立您自己的電腦並調整核心乘數和其他設置,直到您滿意為止。另一種更簡單的方法是找到一台配備可超頻Intel酷睿處理器(SKU 以 K 或 X 結尾)的Lenovo筆記型電腦或桌上型電腦,然後透過 BIOS 或Intel極限調整實用程式 (XTU) 進行超頻試驗。
