🔍 介紹 IPC 和遊戲關係

當今的電腦遊戲愈加要求高效率的處理器。IPC（每週期指令數）與遊戲效能之間的關係值得深入探討。

🎮 遊戲引擎和 CPU 指令循環

遊戲引擎需要與 CPU 進行指令交互。這種交互在不同遊戲引擎中有所不同，因此影響了 CPU 效能。

📈 Intel 指令循環的效能

Intel CPU 的指令循環效能表現出直線性。高時脈率能夠有效提高遊戲效能。

💻 AMD 指令循環的問題

相比之下，AMD 的 CPU 卻未能如此順利。雖然 IPC 提升，但效能提升不及預期。

🔄 如何提高 AMD 效能

AMD 需要採取措施來改善效能。提高時脈率、改進架構等方法都值得考慮。

📊 遊戲和生產力工作負載的比較

遊戲與生產力工作負載的需求不同。AMD 在生產力工作負載下表現出色。

🔮 未來的預測

未來的 CPU 發展趨勢值得關注。預測 AMD 與 Intel 的競爭會更加激烈。

🤔 AMD 和 Intel 的競爭

AMD 和 Intel 在 CPU 市場上競爭激烈。兩者的技術和性能將決定未來的行業格局。

解析 IPC 和遊戲效能的關係

今天我們要深入探討 IPC（每週期指令數）與遊戲效能之間的關係，特別著重於 AMD 和 Intel 兩家 CPU 的比較。在遊戲領域，高效的處理器尤為重要。讓我們一起來了解為什麼 IPC 提升並不一定意味著遊戲效能的提升，以及如何解決這個問題。

這個故事的開始如下：hello frame chaser community today I'm,gonna try my best to explain why the,higher rise in IPC is not scaling with,gaming and also why increasing core,clocks on Rison also doesn't Scale with,gaming it's gonna be kind of a it's,gonna be kind of a rude way of,explaining it I'm gonna be using,Microsoft Paint here but you should be,able to get the gist of it alright let,me go let me just start with this so why,is it that Intel chips scale with clock,frequency almost linearly and why is it,the Reisman ones don't and we're talking,specifically in terms of gaming like the,Rison ones will scale and rendering,applications with clock speed but we're,focusing on gaming here today on this,video so let me bring up paint here and,okay so we know that let me just does,should be thick enough yeah you can see,that all right so we know that Game,engines have instruction cycles in them,and they request things from GPUs and,CPUs in cycles which is obviously the,obviously right but the rate at which,they request instructions from the CPU,is different for every game depending on,the engine etc etc and for the longest,time since you know the last decade or,so instructions have been coated with,Intel processors in mind and you can,kind of think of it in terms of width,depending like an instruction width so,let's say that I'm gonna use blue for,Intel here let's say actually well,use black for generic instruction let's,say a game engine instruction is this,width oh my god now using brush alright,is this width that's not straight at all,let me all right let me use a straight,line here erase this alright it's this,width,alright so let's say that's a game,engine clock instruction width let's say,an Intel chip oops let's say an Intel,chip has the exact same width of an,instruction for a game cycle right,that's an Intel instruction cycle now,let me move this a bit more doesn't,matter you get the point now I'll use,red Verizon and let's assume a risin,ship come on let's assume a rising chip,what is it I think they have about ten,fifteen percent more IPC than skylake so,let's just say a rising chip can accept,an instruction that's 20% larger what is,that Atlas that looks about right there,twenty percent so what happens is let me,just stop to start this is let me just,erase this oops,I'm terrible with paint so let's say we,have a you know,ten nine hundred K at five gigahertz,right and let's say the instruction,cycles bar it's like let's say one two,three oops four five blah blah blah blah,blah these are the Intel instruction,cycles this is a terrible representation,but whatever okay now,let's say these are the AMD ones wait,wait ladies finish this quickly these,are the Intel ones now let's say these,are the AMD ones
