Ryzen 9 3900X

Reviewed in Canada on January 6, 2021

Style: Ryzen 9Verified Purchase

I came from using the ryzen 7 2700X and obviously there is noticeably a big gap between performance, i paired this with 32gb of trident z neo 3600mhx, RTX 2060 Super and have the cpu locked at 4.30 ghz. I could do some more overclocking with my b550 motherboard but it's decent enough, i can render music and videos at fast times without even putting any sort of stress on it. This cpu makes multitasking and gaming a breeze, i never felt this sort of speed with any computer in my life and it's amazing. Great Cpu, make sure you don't cheap out on your motherboard, cooler or power supply. This baby runs hot so make sure you do some research on how to offset the voltage because this thing sucks a lot of power which heats it up to 70 c on idle, unless you have a beast of a cooler. so after playing around with the offset i managed to keep this bad boy at around 70 c under heavy load and around 29 to 33 c on idle. just a quick tip that i had to figure out, overall it's a great cpu, worth the extra coin.

Overkill for gaming, good for dev work and rendering

Reviewed in Canada on August 22, 2021

Style: Ryzen 9Verified Purchase

You don't need a 12 core CPU for gaming. It's overkill. I got it because developer work is very CPU heavy, and this was marginally more expensive than the 5800X at the time. It's from 1 generation ago, so somewhat worse architecture, but it does have significantly higher benchmark scores, and the 4 extra cores (compared to the 8-core 5800X) is a bonus. It's pretty good at rendering. Actually better at rendering than my GPU (as tested by Blender Benchmark), since I went for such a CPU-heavy build. Haven't tried simulations or video editing on it yet, but I expect it to handle those workloads well.

Hot (in not the good way) [Update April 2022]

Reviewed in Canada on July 8, 2020

Style: Ryzen 9Verified Purchase

I learned something with this processor : at 7nm lithography, there is not enough surface area on the CPU die to properly cool it and cooling has become the primary issue with increasing density.

I spent the previous eight years on an eight core(?) FX-8350 and even then, heat vs density was a problem, and that chip would just reset when too hot, which happened to me many times on two different 8350 systems. The reset issue was fixed with the biggest air cooled CPU cooler available and my FX-8350 systems ran smoothly 24/7 under full load. The temperatures were also stable, starting at 30c and slowly ramping up to maybe 50-60c under load.

Holy crap is the 3900x a different beast : it drops its own voltage and clock speeds when it gets too hot, and even with the biggest air cooled CPU cooler available, under load it averages 88c(!), which is only 7 degrees shy of the 95c thermal limit. It is also incredibly spiky, jumping between 45c to 60c in seconds at idle. (Yes my thermal paste is applied correctly and the case has nine fans, five of which are 140mm. I have been building computers for friends and myself for two decades. ). I have noted others have better temps on an air cooled system, but that just speaks to quality variability.

I was going to give it four stars but the cooling problem is systemic, not an inherent design flaw. If they are going to fix it they need to double the size of the CPU die in order to give it enough surface area to get all the heat off quickly enough. Water cooling makes no difference if the heat bottleneck is the topside surface area of the chip.

If you plan on doing long duration full work loads, which are multiple simultaneous EM simulations in my case, the included stock cooler is entirely inadequate. Even short duration full loads with the stock cooler means sitting next to a cooling system running full blast and a chip so hot, it dials its performance back to keep it from prematurely killing itself.

It is damn fast and my multiple virtual machines have never been so snappy. I had to reset what I thought was a “safe temperature” for a CPU though. Some irony that this is the most I have ever paid for a processor.

[April 2022] Still going strong - I tend to put it into low power mode which parks half the processors when working and change it back to “balanced” when doing anything more that needs a kick in the pants. It hasn’t hard reset because of heat unlike the previous FX8350.

Stable, powerful, overclockable, and best value

Style: Ryzen 9Verified Purchase

This chip hits the price-performance sweet spot and is compatible with motherboards that support the fastest DDR4, PCI 4.0 and the newest ultra-fast hard drives. So going with this Ryzen CPU is the future-proof choice. As the image shows, the Ryzen 9 can be overclocked to 4.21Ghz with no stability problems at all, but if you push it, water cooling is a better choice. That way, I could not heat the Ryzen 3900X beyond 80C in a torture test, and it cooled quickly as the workload dropped.

I upgrade from a Core i7 6700K OCed to 4ghz with 32 GB of Corsair Dominator Platinum 3000mhz DDR4 Ram in an Asus Maximus VIII Hero motherboard and an Asus Geforce 1080 Strix video card.

My Benchmarks for this system were:

Cinebench R20 - 2167
Heaven Score - 3146
3D Mark Timespy
Overall - 6930
CPU - 4976
GPU - 7446

I built my new AMD 3900X system with an Asus Crosshair VIII Hero and G.Skill Trident Z Neo RGB 3600 mhz DDR4, and moved my 1080 over to my new system since I am planning to upgrade my video card when the next gen of Nvidia cards come out. Here are my scores doing the same benchmarks.

Cinebench R20 - 6947
Heaven - 2839
3D Mark Timespy
Overall - 7897
CPU - 12934
GPU - 7390

Overall I have noticed a huge improvement over my older system but have noticed some changes in performance. Keep in mind I play a lot of games so performance has improved in general its way better if not this completely smashes the 6700K but in some tests performance took a slight decrease. This was noticeable for me when I played minecraft with my son on a modded server where my game was slower then my intel system. Overall though this CPU is a big upgrade and my son can finally upgrade his old 8 year old pc to a 4 year old system now and I can take advantage of some of the latest hardware really happy with the results and recommend this CPU to anyone who wants that extra performance.

O melhor do mercado!

Reviewed in Brazil on April 14, 2021

Style: Ryzen 9Verified Purchase

O Ryzen 9 3900X é simplesmente incrível! É a escolha definitiva pra quem quer o melhor do mercado. São muitos núcleos e threads para usar a vontade. O software da AMD ajuda também muito a otimizar o uso de energia pra atividades mais básicas quando precisar. O cooler box é lindíssimo, pra quem gosta de RGB é um colírio para os olhos e se você possui uma placa mãe com controladora RGB, no meu caso o Asus Aura Sync, você sincroniza as cores de tudo.

Eu trabalho com desenvolvimento de jogos e esse processador acelerou muito todos os processos na computação gráfica, se você trabalha com edição de vídeo pesados ou modelagem 3D, é custo é alto, mas o benefício é muito maior. Agora se você pensa em adquirir somente para jogar, aí talvez não seja uma boa opção, visto que o salto de desempenho dele para o Ryzen 7 é pouco. Na balança do custo benefício para jogos, ele pode não ser interessante. Basicamente o Ryzen 7 já é capaz de fazer tudo que precisa para jogar, o Ryzen 9 é muito a frente do tempo, então os jogos acabam não usando todo seu poder e definitivamente não existe placa de vídeo para gargalar esse processador, ele é muito potente mesmo para a placa de vídeo mais potente do mercado atualmente.

Volví a enamorarme de AMD

Reviewed in Mexico on January 23, 2021

Style: Ryzen 9Verified Purchase

The media could not be loaded.

Yo desde que pude elegir mi PC siempre elegí AMD, pero como muchos saben, hubo un tiempo en que sus procesadores no daban la calidad o rendimiento deseable ante la competencia, motivo por el cual me cambié a intel por un par de años. Desde la llegada de ryzen todo eso cambió y eso provocó que volviera a donde pertenezco. Debo decir que si, si ustedes buscan reviews en Internet, el nuevo ryzen 7 5700x le da vuelta a este procesador en juegos por el mismo precio, pero en productividad esos núcleos extra siguen dándole una ventaja interesante tanto con el ryzen 7 así como contra intel y lo que pudiera ofrecer (para productividad) por lo que debo decirles que aún en 2021 es una excelente alternativa este modelo (y no sus hermanos mayores de la serie 3000) tanto por el precio como por el hecho que su dicipador de stock es perfecto para mantenerlo fresco sin problema alguno, es un procesador maravilloso para trabajar y para el gaming se defiende aún sin problema alguno. Quizás si hubiera una queja seria la poca pasta térmica que trae de stock, pero nada que al cabo de 1 año o 2 puedas cambiar por una de mejor calidad. Como dato adicional ese cooler que trae va perfecto para poner todas las rams sin problemas siempre que no sean exageradamente altas, aunque bueno, si le vas a acompañar con rams con dicipadores altos (por ende rams costosas) invertir en un enfriamiento líquido no suena a mala idea.

Insanely fast

Reviewed in the United States on April 7, 2020

Style: Ryzen 9Verified Purchase

upgraded from my Ryzen 7 to this Ryzen 9 3900X for gaming cache. First off its insanely snappy. Will run a bit hot even with liquid cooling. If you buy this get liquid cooling. So right out of the gate my RTX 2700 Super Founders Edition had insane eye candy and much better speed. Anything you through at it will open at break neck speeds. Your mouse will be your enemy. It will move entirely way too fast due to its processing power. This thing mops the floor with all the Intel Chips ive ever owned. Even my I9 chips dont game or compute as this chip does. Its a must have if you want to play video games and do insane amounts of processing. It operates on all buses on your system board quite efficiently. Ive been debating messing with my memory timing as I have AMD Ryzen Memory Ready RAM which automagically times with the system clock of the CPU and AMD Ready Ram will run at 3600 MHz. You must set your XMP/DOCP option in the BIOS. But Ryzen makes efficient use of PCIE 4.0 and its fast. You wont be disappointed other than it will push some heat but running any gaming on a 70 MEGS of video cache dedicated to video rendering makes this a seriously badd chip for anything you want to do. Its smoking intel and I have been an Intel Fan for so many years until this thing fell into my hands. All I do for a living is work on PCs Desktops Servers, and Land based internet I go home to this and appreciate all it does. It will not disappoint and will stay strong for years. This absolutely buries Intel. Worth every penny I put towards it. Now my Ryzen 7 2700 will sit in its plastic case. Trust me I had to do it. When I play Ghost Recon with my son it looks as though he is Sprinting it renders frames so fast. The game runs so quick with playing with other gamers your mouse will piss you off you will have to lock the frame rates on your mouse and they move so fast on your screen its simply amazing. Eye candy with games coupled with a NVIDIA RTX you will be amazed. Okay not a fanboy of Ryzen but I love this chip. See how it holds up and I am a verified user.

Processore al top della categoria consumer per qualsiasi uso, gaming compreso

Reviewed in Italy on December 23, 2020

Dopo anni di onorato servizio, dovendo lavorare molto con software come Photoshop e Premiere Pro, ho dovuto pensionare il mio Intel Core i7-2600k. Sebbene abbia aspettato l'uscita dei nuovi Ryzen 9 5900x, la loro mancata reperibilità nel mercato (se non a prezzi elevatissimi) mi ha fatto valutare seriamente il Ryzen 9 3900x, e devo dire che, complice una buona offerta, non mi pento minimamente di questa scelta.

Leggendo sul web, tra forum, reddit e recensioni, sono tutti talmente entusiasti delle prestazioni in single-thread della nuova serie Ryzen 5000 da trasmettere la sensazione che la serie 3000 (e nella fattispecie il 3900x) andasse male o comunque non fosse performante, che insomma fosse lento nel single-thread. Avendo una cpu (l'i7-2600k) che invece è sempre andata molto forte nel single-thread, non riuscivo bene a capire se, in caso di applicazioni fortemente single-threaded (come alcune funzioni di Photoshop) avessi notato differenze sostanziali o se potessi rimanere "fregato" in questo ambito.

Ebbene, la differenza è *ABISSALE* in single-thread, mentre è come trovarsi in un universo parallelo quando si usano applicazioni multi-threaded, come ad esempio Handbrake, Starxrip o Premiere Pro, nell'ambito dell'editing ed encoding video.
Un esempio: l'esportazione di uno specifico video su Premiere Pro è passato da 12m40s a 2m26s.
Ero scioccato.
Non soltanto: se si abilita l'accelerazione hardware nvenc delle schede nVidia che la supportano (nel mio caso ho una GTX 1070 OC 8GB) l'utilizzo della GPU in fase di encoding passa dal 20% (con il 100% di cpu) dell'i7-2600k al 90% con il 10% della cpu del Ryzen 9 3900x.

In gaming il paragone è altrettanto impietoso, ho guadagnato almeno il 120-140% di prestazioni in modalità multiplayer di come Battlefield V e GTA V: nel primo, soprattutto, son passato da una media di 30-35 fps ad una di 80-85 fps. L'i7-2600k non riusciva più a gestire bene le modalità multiplayer di tutti i giochi che graficamente già impegnavano molto la CPU e la GPU.

Insomma, soddisfatto? No, soddisfattissimo!

Un consiglio spassionato però: investite in un buon dissipatore e in un buon case, poiché è un processore che riscalda molto. Io ho preso un dissipatore ad aria Be Quiet! Dark Rock Pro 4 e un case Be Quiet! Pure Base 600 e mi trovo ad avere temperature a 35°C in idle e 55-58°C in full, il tutto in assoluto silenzio. Usando il dissipatore stock e/o un base con un pessimo airflow, il rischio di toccare 80-85°C e di mettere sotto stress la cpu è concreto.
