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!

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!

Ryzen 3950x ou i9900k ? Maintenant que j'ai les deux, difficile à dire

Reviewed in France on February 21, 2020

Style: Processor OnlyVerified Purchase

J'hésitais... mais j'ai finalement pris les deux à six mois d'intervalle... Et je dois avouer que les deux se valent même si l'I9900K est beaucoup plus rapide sur un seul Thread (jusqu'à 5,100 Ghz en OC) que le Ryzen qui flanche à partir de 4,2 Ghz (On parle de jusqu'à 4,7 ghz en turbo, mais non... en pratique et avec le supercooler qui va avec, il monte maxi et demeure opérationnel à 4,175 : l'I9 est bien plus stable même à 5000 Mhz). Le truc du Ryzen demeure le rendu et la gestion multithread où là il fracasse l'I9900K (6400 pour l'I9 sur Cinebench et 9600 pour le Ryzen 3950x). Mais il n'y a pas que le rendu dans la vie me direz-vous... C'est là où il faudra faire un choix, ou faire comme moi, en prenant les deux et en jonglant avec, dans un Workflow sur mesure.

RYZEN 3950X por fin en Amazon mexico!!!!!

Reviewed in Mexico on February 7, 2020

Style: Processor OnlyVerified Purchase

Pues llego en tiempo y forma, como siempre amazon México con un servicio excelente, el procesador venía en una bolsa sin ninguna indicación de que es frágil afortunadamente el empaque del cpu es resistente, es un delite el solo hecho de tener la caja y verlo.

Después de 3 días de empezar a usarlo es increíble tener tanto poder en un espacio tan pequeño, en si el cpu es pesado a comparación con el 1800x (el cual estoy actualizando), la mobo al que se lo instale es una crosshair vi hero x370, y va de maravilla, tenia mis dudas por el tema de la potencia pero al activar el precision boost overdrive, puedes darte cuenta que la placa esta sobrada en potencia, El oc máximo que se ha intentado es de 4.4 a 1.35v con una compensación a 1.41v a una temperatura máxima de 84°c la puntacion en CBR20 fue de 10,100 impresionante subir de 9,049 en stock mas de 1000 puntos, todo esto refrigerado por un kraken x72 en una configuración de 6 ventiladores noctua a 3000rpm (push and pull), en cuanto a ram se refiere son unas trident z a 3000mhz que perfectamente son estables con un oc a 3600mhz con 1.35v, afortunadamente aun son chip samsung B-die, eso ayuda bastante.

Cabe hacer mención que después de varias pruebas el voltaje puede bajarse aun mas, ya que lo permite,con lo que se podría pulir un poco el tema del calentamiento, o al contrario intentar subir la frecuencia pero sinceramente no veo necesario hacerlo ya que con el hecho de poner las ram a 3600mhz, y activar precision boost overdrive, se logra un buen incremento en el rendimiento claro no comparado con un oc manual pero se podría decir que es una media, logrando 9,590 en CBR20 a una temperatura de 73°c, en procesos cotidianos con este cpu considero es lo mas adecuado, ya que si se tiene un sistema de water cooling costum valdría la pena el oc manual a mi consideración todo depende de los parámetros.

En conclusión es un cpu monstruoso por el precio que tiene y comparado con mi antiguo 1800x y un olvidado 1920x es un cambio bastante radical, ya que se acaba de juntar en un solo equipo lo mejor de dos mundos gaming y workstation.
