Gaming Hero

Reviewed in the United States on December 30, 2018

Style: 9900KVerified Purchase

Let me start by saying I'm the dad and would not have purchased this. However, my son wanted to build his own gaming PC for Christmas and since I was foolish enough to say make sure you get the best components you can because I don't want to upgrade your machine in a month, he bought top of the line products. And let me tell you this,... this thing cranks! My son is the envy of his gaming buddies and they all drool over it's performance. If you are building a gaming PC and want top end performance, then buy this. If you are a dad and want to become "D. O. T. Y,(Dad of the Year)" buy this. This is absolutely 14 year old approved.

P.S. I got socks for Christmas :)

Great processor, just a side note the Asus Maximus XI series motherboards come with 4 phase VRM and can barely clock this at 5ghz stable. Do not pair this processor with an Asus motherboard - this is coming from someone who almost exclusively buys Asus motherboards for PC builds since 2007

High temperature and throttling

Reviewed in the United States on November 7, 2018

Style: 9900KVerified Purchase

It is a beast when combined with Asus z390 Maximus hero and 32gb gskill 3200 cl14 but..forget about overclocking though it runs very hot already Intel has push it as far as they could compete with the market right now with AMD,
it runs very fast but it also down clocks it itself a lot because of the temperature and the power limit,
I have Noctua NH-D15S with two installed fans and temperature rises up to high 70sC and spikes to mid 80sC while gaming that's just unacceptable high temperature comparing to an i7 5820k overclock to 4.2 was mid 50s c with a smaller CPU Cooler.
the clocks doesn't stay steady unless you fiddle with the BIOS and it takes a lot more than 95 watts and I have spiked up to 180 Watts just on the CPU.
This CPU obviously needed a die shrink but intel was in a rush to release this processor to compete in the market..
Other thoughts: it is a must have really good CPU Cooler and even then it will run very hot...

Slow shipping, faster than CPU it replaced

Reviewed in the United States on November 18, 2018

Style: 9900KVerified Purchase

Took a month to arrive so minus one star. Tempted to chop off another star because I expected to get 10nm by now. But they did well enough with this yet-another-14nm CPU. Let's all take a moment of silence as Moore's law is officially laid to rest. RIP.

-Performs 40% to about 100% faster on all of my workloads than the 4-year old 6-core 22nm i7-5820K it replaced.
-I9 consumes only a fraction of the power and less heat at low utilization compared to that old x99 chip.
-Peaks at about 176 watts after 12 minutes of running P95 torture test. Temps briefly peak in low 80's for that dated and unrealistic test. (Motherboard maker monitoring software shows mid 70's, Intel software shows low 80's...)
-Except for initial setup and testing, I don't manually overclock the 9900k since that would only give me about 3% more performance than I get running optimized with no power restrictions enabled (e.g. out of Intel TDP spec, but the common default for these early Z390 boards). Just disable the throttles and enable auto for the voltage and stuff.
-5.0 GHz for common few core load for long periods, and 4.7 GHz on all cores forever under heavy load (e.g P95) is what I'm seeing with the above config. I'm just using basic H115i PRO AIO cooling and have yet to see any workload force throttling to the official 3.6 GHz speeds.
-Times have really changed since my hard core overclocking days 20 years ago. With throttles disabled, the CPU does exactly what I would want to achieve. It's organic overclocking virtually out of the box. Turbo boosts to workload optimized fantastic speeds when needed, reduces down to less than 25 watts TPD when not under stress even while still hitting 5.0 Ghz. I don't have to do any switching or adjustments between workloads. No distractions. Perfect!
-Unlike the much more expensive xx99 chipsets, Z390 enables Intel onboard GPU with Quick Sync for better performance and lower CPU utilization/power consumption, which is something I have long missed for some of my workloads, one of which runs 24x7.
-Seems to be a great price if you compare to x299 platform prices. Thanks to AMD's innovation, Intel is cannibalizing its own HEDT segment.

It's marketed as a gaming CPU, but IMHO it's a great choice for workstation needs. There's a lot of frustration in the 12-year-old-at-heart gaming community with this chip. It's expensive for that market segment especially with prices inflated
due to the 14nm shortage, it lacks much innovation over last year's offering which upsets the frequent must-have-the-latest upgraders, and there's really not that much headroom for overclocking without industrial cooling equipment.

If you have an older (3 years+) CPU and looking to rebuild your system and want to invest in a high performing chip at a comparably reasonable price (compared to x299/HEDT platform and adding in extra cost due to the 14nm supply shortage), I9-9900K is a fine choice that gives you the latest and greatest. It's a safe bet since Intel's 10nm performance chips are likely now a 2020 thing.

If you want more value, get AMD's latest. We all owe AMD's innovation some gratitude for forcing Intel to offer this 8-core chip in this segment. Long live AMD.

Awesome gaming CPU, bring a great cooler.

Reviewed in the United States on November 12, 2018

Style: 9900KVerified Purchase

Works fantastic, easily clocks to 5ghz on all cores, however be prepared for some serious heat, especially under load and/or bench-marking. Make sure you have a decent sized AIO water cooler or a super awesome amazing air cooler before attempting to overclock or push this chip.

Performance wise my focus is purely gaming, and it eats games for breakfast. Playing at 100fps on brand new titles like Assassin's Creed Odyssey like it's nothing, plenty of headroom to spare. Barring any massive game changing development in the next few years (DDR5 ram er, maybe?) this should future proof you about as well as any chip could, probably 3 to 5 years depending on what next gen consoles launch with (Meaning if PS5 launches with 16 cores (very doubtful) that may become the standard for games and your 8 core 16 thread pc starts looking old hat (even more doubtful). ANYway, barring something totally left field like that, I can't see anything gaming wise this thing won't be able to devour for years to come.

I'm satisfied with my purchase, and the price (bought at $530) IS high but doesn't bother me too much because they have a price point for most everyone, with 9700k, 9600k, 8700k, all more than capable of fantastic gaming performance at lower price points.

Let's be clear, I'm of the opinion you don't buy this for gaming because you need it, you buy it because it's the best (mainstream) cpu out there, and because you feel future-proofed (maybe, possibly, you never know). I like knowing I've got tons of power to spare for that next big game coming next year. If you feel the same, then go for it, you'll likely love it. If you have budget constraints and need to choose between this or a great gpu, definitely prioritize the gpu and buy a 9700k, 9600k, or even the 8700k or 8600k depending on how much you have left.

And also the packaging is pretty so you can display it and show it off to your friends. 0.o

CHECK THE PROCESSOR BEFORE BUILD.

Reviewed in the United Kingdom on July 21, 2019

Style: 9900KVerified Purchase

As headline suggests, check the processor before you build with it, I ordered this and the first thing I noticed was the processor inside the box was a Celeron e3400 worth about £5.

there are snakes out there buying this cpu, replacing it in the box with the Celeron which looks identical besides the faint writing on the cpu and then sending it back SEALED. this obviously causes the person dealing with the return to simply restock it without checking and then you could end up with it just like I did.

I spoke with amazon rep who immediately sent me a replacement and strangely the replacement had a sticker saying brand new and also the bag the processor comes with, so keep this in mind when ordering, if you have no black bag it could be a previously returned product, CHECK IT. anyway as I say amazon replaced it straight away, didn't ask me to return it first just sent a new one straight away provided I agree to send this one back and they were very polite and sympathetic, seemed to take it seriously which was nice but I do fear this will end up in somebody elses hands.

as for the processor, mine appears to be golden, overclocks like a champ on pretty low voltage and temps are pretty good indeed, better than expected on a 280mm rad. was mighty tempted by ryzen 3900x but when I really thought about it I wasn't going to use it for its strongest use case and the 9900k will push my 2080ti a bit further, then the price dropped on the 9900k to £405 so it became good value at that point too.

I want to rate it 5 stars, but I want to get your attention too so you don't get a computer built and then realise what happened. for that reason and amazons lack of checking the returns properly ill rate it 1 star.

Future Proof?

Reviewed in Canada on February 15, 2019

Style: 9900KVerified Purchase

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.

Packaging was awful however the processor is fine

Reviewed in the United Kingdom on December 5, 2018

Style: 9900KVerified Purchase

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)

Very nice 👍

I’m pretty happy with my new upgrade.
Windows is running super fast by using the game boot mode. Got it over clocked to 5.20 gigahertz with out any heating problems. Temp is staying around 36 to 24 when idle. I’m very happy with it. I totally recommend this CPU.

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

Style: 9900KVerified Purchase

【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。
