Drop in replacement for my 3 year old 1800x (which served me well). Updated the BIOS on an x370 motherboard et voila! This monster is supported!

I love it! More cores than you know what to do with, and an incredible single thread performance to boot. Incredible power efficiency as well.

This is the best mainstream CPU on the market by quite some margin. I don't see myself upgrading any time soon, unless AMD changes the game yet again!

Arrived before Xmas, you must spam refresh to purchase this. Did not include promotional games :(

Reviewed in the United States on December 2, 2019

Style: Processor OnlyVerified Purchase

Wonderful chip, no issues, however Amazon honoring their promotional partnership with AMD...not so much. The main ad on this product page shows “Equipped to Win” on the poster, AMD main sites shows the promotion qualifies to Ryzen 9 3000 series and Amazon as a selling and participating partner....very deceiving.

12/13/19 Edit:
After reading a a recent review from another gentleman on his success with receiving the promotion code, I decided to go through Amazon customer service once again. Please let me assure you, the process was frustrating and difficult. However, next day I was emailed the code. Good luck.

Excellent CPU but no game bundle from Amazon

Reviewed in the United States on December 4, 2019

Style: Processor OnlyVerified Purchase

First off, yes, this CPU was very hard to get. No time announced for when it would go on sale, broken search linking preventing the product page from being found without knowing exactly what to search for, and finally when the listing did go live it said you couldn't order it unless you went to the list of sellers and specifically selected Amazon. Very strange. To make matters worse, the product page only showed the minimal info on launch day so there was no way of knowing if Amazon was going to offer the game bundle or not. Then when they got around to updating the page with the missing info, they added the info direct from AMD implying the game bundle was included. Well, guess what, it's not. I opened a ticket with Amazon support about it and was told they received no game bundle codes from AMD and I should go ask them about it. Um, yeah, sure. And the FAQ on the AMD rewards site specifically says it's on the retailers to distribute the codes. So I and the others who managed to score one of these on launch day are out of luck there. I'm tempted to deduct a star for that but I don't want to take anything away from the CPU itself.

Alright, enough complaints about the low stock, strange order process, and misleading game bundle info. The good news is this CPU is every bit as good as the reviews say it is. So far after a solid day of testing I can say it's a crazy fast compute monster that runs cool, stable, and relatively quiet on my MSI MEG X570 Unify motherboard with a Noctua NH-D15 air cooler and 64GB (2x32GB) of Corsair Vengeance LPX DDR4 3200 C16 memory (CMK64GX4M2E3200C16) overclocked to 3600-18-22-22-42. The other important bits in my system build are a Phanteks Enthoo Luxe case, Seasonic FOCUS GX-850 (SSR-850FX) 80+ Gold power supply, EVGA GeForce RTX 2080 (08G-P4-2081-KR) video card, and 1TB Samsung SM961 NVMe SSD running Win10 Pro 1909. You can safely ignore AMD's water cooling recommendation as long as you get a good air cooler and ensure good air flow in your case. Power consumption is amazingly low for such a powerful CPU. Sure, it's going to pull more total power than low and most mid-range CPUs but this is still an extremely efficient processor. Gaming performance is excellent. Maybe not quite as good as Intel's best gaming CPUs but close enough provided you don't game for a living. On the other hand, this thing rules the roost in video encoding. It's amazing. I do a mix of both so this CPU is the perfect balance for me.

Great CPU, runs HOT

Reviewed in the United States on December 17, 2019

Style: Processor OnlyVerified Purchase

I was fortunate enough to get one of these by chance; I had been refreshing the product page a few times a day and it just happened to be in stock, so I bought it. I got all the parts needed a few days ago, rebuilt my machine, and it is running great. No issues so far other than having to upgrade my CPU cooler because this chip runs very hot. Docs from AMD says the design spec is 95 degrees C - and they weren't kidding. This isn't necessarily bad, just something to keep in mind if you are planning to upgrade an older rig.

Motherboard: Gigabyte x570 Aorus Xtreme
RAM: G.SKILL Trident Z Neo 64GB (F4-3600C16Q-64GTZNC)
Boot drive: Sabrent 1TB Rocket NVMe 4.0 Gen4 PCIe M.2 Internal SSD
Storage: 2 x Samsung 860 EVO 4TB

I kept my case, power supply, and graphics card.

Was fortunate enough to place an order for this CPU during the .00002 seconds it was in stock! Amazing processing power for the price. I have had Intel CPUs for the past 10 years due to no other good options, but AMD has really turned it around. This is why competition is great for the consumer!

Sehr gute CPU mit einem Aber

Reviewed in Germany on April 5, 2020

Style: Processor OnlyVerified Purchase

Fangen wir beim Guten an

Die CPU bietet für einen vergleichsweise günstigen Preis 16 Kerne und dazu noch eine exzellente Single Core Performance die en Par mit der Konkurrenz ist, zudem ist der Einstieg in die Platform (am4) verglichen mit anderen die ähnlich hohe kernzahlen bieten günstig. Man muss sich aber auch im Klaren sein, dass man auch eine Anwendung braucht die die Kerne tatsächlich auch nutzt sonst ist man mit günstigeren Produkten besser dran die weniger Kerne haben. Hier liegt auch das größte Problem der CPU sie richtet sich auf einer normalen Consumer Platform mit all ihren Limitierungen offensichtlich an professionelle Nutzer was mich zu den cons bringt.
Cons
Da der Chip nach wie vor ein Consumer Chip ist unterstützg er nur avx2 nicht jedoch avx512/256. Allerdings sind viele professionelle Anwendung stark auf avx512/256 (Matrix und Vektor operationen) optimiert. Ist das der Fall würde die CPU selbst im Vergleich zu einer mit weniger Kernen definitiv den kürzen ziehen und der Unterschied kann massiv sein. Hinzu kommen andere Limitierungen wie die Beschränkung auf 128GB die RAM, die relativ geringe Anzahl an pciE lanes (Multi GPU kann ein Problem werden dadurch in Profi Anwendungen).
Fazit:
Ja man kann mit der CPU spiele spielen ohne sich über einen Bottleneck Sorgen machen muss. Ja die Kerne sind schnell. Aber beides erreicht man exakt genauso gut mit einer 8 kern CPU dadurch richtet sich die CPU in meinen Augen definitiv an Leute die mit professionellen Anwendungen arbeiten und durch die Limitierungen der Plattform macht sich der 3950x dadurch zu einem Nischen Produkt. Bearbeitet man nur excel Tabellen, schreibt Mails, oder spielt ist sie Overkill und man schmeißt Geld raus. Ist man ein Professional und profitiert von avx521/256 sollte man zu einer anderen Platform greifen. Fällt man aber in die Nische wo das nicht der Fall ist bekommt man hier ein exzellentes Produkt das in dem Bereich konkurrenzlos ist.

Perfekte CPU fürs Streamen und Gamen an einem PC...

Reviewed in Germany on March 11, 2020

Style: Processor OnlyVerified Purchase

Ich habe mir die AMD Ryzen 9 3950x CPU gekauft, um an meinem Gaming PC zu streamen. Was soll Ich sagen, 16 Kerne (32 Threads) reichen vollkommen aus, um bei Ultra Auflösung (GTX 1080TI) und Streaming Encoder: 1080p, 60Hz, X264, Mittel auf Twitch zu streamen. Die CPU Auslastung steigt hierbei nicht über 25%. Gekühlt wird die CPU mit einem Asus ROG Ryujin 360 AIO Kühler auf einem Asus Strix X570-E Gaming Board. Knaller!
Ich hatte am Anfang extreme Bedenken, von Intel auf AMD umzusteigen, aber meine umfangreiche Recherche im Internet und bei Freunden, die wirklich Ahnung haben, hat im Ergebnis eindeutig für AMD gestimmt. Ich bereue es keine Sekunde, von Intel auf AMD umgestiegen zu sein! Absoluter Kauftipp!

il meglio su piazza per pc desktop

Reviewed in Italy on April 7, 2020

Style: Processor OnlyVerified Purchase

Preso questa cpu poche settimane fa, passando da un AMD 1700.. che dire, la differenza è abissale. Il numero di thread la fa una cpu ideale per pesanti carichi di lavoro, per app professionali, editing foto/video, creatori, eccellendo anche in gaming; anzi, visto sempre il maggior supporto per multithread è chiaro qual è il futuro anche del gaming, quindi anche in questo senso è un acquisto assolutamente azzeccato e lungimirante.
Ideale il fatto che si possa fare upgrade anche da motherboards economiche volendo su AM4, io per esempio ho una Asrock AB350M pro 4, e la cpu (senza overclock, che comunque non mi interessa, dato anche l'incremento di consumi notevole che si ha con overclock pesanti su queste cpu) va a meraviglia; AMD consiglia impianti a liquido, ma se non si fa overclock basta anche un dissipatore ad aria adeguatamente dimensionato (ho preso un dissipatore di arctic cooling da 30 euro che fa benissimo il suo lavoro, in perfetta silenziosità).
Un'accortezza può essere quella di abbinargli memorie almeno da 3200 mhz con timings tirati, oppure di frequenza più elevata, ma se ciò non fosse possibile sicuramente le prestazioni saranno ugualmente sorprendenti.
Inizialmente ero indeciso se prendere questo o il 3900x, ma poi visti i cores in più ad un prezzo che non è molto più alto ed il tdp accettabile raccomando il 3950x per pc desktop di fascia alta che secondo me è la scelta migliore.
Certo più di questo c'è il 3990x, con ben 64 cores e 128 threads, ma lì si parla di un socket diverso, solo mb ATX disponibili e costi non alla portata di tutti (anche se comunque in linea come rapporto prezzo/prestazioni!), quindi cpu come il 3990x rimangono appannaggio di professionisti molto esigenti o aziende.. oppure enthusiasts!
Dopo anni di stagnazione nel mondo delle cpu AMD è tornata in campo alla grande ed ha dettato qual è il nuovo standard delle prestazioni per cpu
