5.0 out of 5 stars Future Proof?
Reviewed in Canada on February 15, 2019
It was time to upgrade from an 8 year old, yet still capable, Core i7 2600K. I'm hoping this 9900K will go the distance and take me to year 2030. No plans to overclock it yet but at least it's capable of it when needed.

I was pleasantly surprised to see that, yes, this chip does come packaged in a giant 12-sided die. Sadly I had to go to YouTube to figure out on how to open it. I installed the CPU with ease onto a Gigabyte Z390 Aorus Master motherboard. For cooling I installed a Corsair H115i Pro AIO onto it. Runs beautifully. System is used 30% gaming, 70% creation (CGI/animation, CAD). Eventually I hope to use it for time travel.

I'll update the results in 10 years if Amazon is still around. Lol.

4.0 out of 5 stars 最良のゲーミングCPU、ただしコスパは悪い
Reviewed in Japan on December 6, 2018
【温度・消費電力について】
Intel Core i9 7900Xの登場以降、Intel CPUは検証機材に使用するマザーボードに依るとはいえ基本的にIntelの仕様を満たす電力制限が無効化されているので、「Intel Core i9 9900K」も例にもれず多くのレビューでCPU温度と消費電力が非常に高いと評価されることが多いですが、当然ながら、電力制限をIntelの仕様に合わせて設定すれば問題なくTDP95WのCPUとして運用することができます。TDP95Wに制限した場合の性能についても各章で紹介した検証結果の通り、全コア4.7GHzで電力制限を無視した時よりは当然下がりますが、それでも8コア16スレッドCPUらしい性能を発揮しており、決して”爆熱”等の誹りを受けるCPUではないと思います。

ただしマザーボードが電力制限を無視している設定を標準設定に採用しているケースが多いことも事実です。電力制限自体は簡単な設定ではあるものの、一般ユーザーがそのまま使用するとほぼ確実に全コア4.7GHzの動作になることが予想されるため、検証結果の通り一般的な空冷CPUクーラーでは運用が難しくなっており、「Intel Core i9 9900K」で自作PCを組むのであれば240サイズ以上の簡易水冷CPUクーラーを使用するのが無難です。

【クリエイティブ性能について】
3Dレンダリングや動画のエンコードなどコンテンツクリエイトに関する性能では、長らくIntelのメインストリーム向け最上位として君臨し続けた4コア8スレッドCPUの最後を飾ったCore i7 7700Kに対して概ね2倍近いパフォーマンスを発揮しています。

同じく8コア16スレッドで競合製品のRyzen 7 2700Xと比較すると、3DレンダリングやRAW現像については動作クロックの差で性能がそのままスケーリングする感じです。動画のエンコードについては既知の情報ですがRyzen CPUが比較的に苦手とする分野なのでCore i9 9900Kや下位モデルのCore i7 9700Kが上位に食いこんでいます。ただしCore i9 9900KとCore i7 9700kは従来比で価格が跳ね上がっているので、コアスレッド数でそのままRyzen CPUと競合製品として比較してよいのかというと疑問が残ります。現状ではRyzen 7 2700XとCore i5 9600Kがほぼ同じ価格なので、クリエイティブ性能のコスパを考えるとRyzenに軍配が上がるかなと。

【ゲーム性能について】
100FPSオーバーハイフレームレートにおけるCPUボトルネック緩和に関しては下位モデルCore i7 9700Kや前世代最上位Core i7 8700Kを上回る性能を発揮しています。Core i7 7700Kの全コア5.0GHzを軽く超える性能だったということには、ここまで差が出るのか!と地味に驚きました。オンライン対戦FPSなどハイリフレッシュレートのゲーミングモニタと組み合わせてハイフレームレートを維持することが勝率アップにつながるゲームではCore i9 9900Kは最良の選択肢になることは間違いないと思います。

フルHD~4K解像度の60FPSターゲットであれば4コア4スレッド以上の最新CPUであればどれを使用しても大差はありません。ただし60FPSターゲットであってもAssassin's Creed OdysseyのようにCPUによって差が出るケースもあるので、Intelのメインストリーム向け最新CPUのPCゲーミングにおける安定性にはやはり信頼がおけます。

3.0 out of 5 stars Packaging was awful however the processor is fine
Reviewed in the United Kingdom on December 5, 2018
The packaging on this was extremely sub par in my opinion. I attached images, in one of which you can see two broken pieces of the plastic along with a crack (there is one more crack on the same point but on the other side) and an image of the packaging itself. (I don't understand how they screwed that up to that degree as there is too much loose space) either way you can look at the images and decide for yourself,

Though the package is damaged and the packaging itself was sub par. The processor itself seems undamaged and I don't think it should have any problems. Though if it does not work I will update this to 1 star. I think they should have packaged this much better and perhaps had a fragile label on the packaging, I'm disappointed in the fact the container thing for the processor is cracked and has parts broken off as to many I assume the thing is somewhat of a collector's item to have on display... But with it being damaged it looses some value in that regard.

Edit: I have been using the CPU for over a week at this point and have had no issues with its performance and it is working as it should. though first impressions do matter and as such I will be leaving my review as a three star one because others might not be so lucky. especially if the packaging being done like this is a standard thing. (though I may have been unfortunate and could be an outlier)
