CPUの選び方、Intel&AMDの性能と価格、レシオでコスパを判断

投稿日:

自作PCを作ってみようと思い立ったが、どのCPUを選べばいいかわからない。

なので、一つの判断材料として性能&価格でレシオを比較してみよう 

 


PC自作の鉄則! 2020 (日経BPパソコンベストムック)

 

絞り込み

とりあえず比較してみようと思い、ドラパラのサイトに載っていた性能目安(IntelAMD)を参考に比較してみた。

おそらくこの性能目安は、CINEBENCH(シネベンチと言われてる?)とかの
アプリでベンチマークテストを出しているものだとおもいます。

表の全てを比較するのはめんどくさすぎるので、

・性能目安1000以上
・IntelならCore iシリーズかXeon
・AMDならRyzen

で絞り込んで比較します。

 

価格調査

上記で絞り込んだ物の中で、Amazonで実際に購入出来る物の値段を調べてみました。

やはり高いものはうん十万とするので、

初心者が購入するのには、あまり現実的ではないと思い、

5万円以下で比較してみました。

IntelCPU
グラフにしてみた結果

勝手な印象

・第3、4世代のCPUは今新品で買うと、性能の割に値段が高い。
・新しいCPU(第9,10世代)は意外とコスパがいい。
・少し前のXeonはコスパいい

AMDCPU
グラフにしてみた結果

勝手な印象

・Ryzen7は全体的にコスパ悪い感じ
・Ryzen5 2600Xがバランスよくコスパいい感じ


AMD CPU Ryzen 5 2600X with Wraith Spire cooler YD260XBCAFBOX

ASRock AMD B450チップ搭載 Micro ATX マザーボード B450M Pro4

 

マトメ

Intelなら少し前のXeonか、新しいi3とかがコスパよさそう。

AMDならRyzen5 2600Xがいいかな。

今回は性能目安のみで比較したので、

コア数やスレット数、それぞれのCPUの特性などは一切考えていません。

これ以外に、マザーボードや電源など、
それぞれに合った物を購入する必要があるので、
それらを合わせるとまた違う結果になるかもしれません。

この記事は参考程度に宜しくお願い致します。

間違いやご指摘がありましたらよろしくお願いします。
