Let's start with the basics. The AMD Ryzen 9 3900X boasts a base clock speed of 3.8GHz and a boost clock speed of 4.6GHz, making it one of the fastest processors on the market. With 12 cores and 24 threads, you can be sure that your PC will be able to handle even the most demanding applications and games. And with a whopping 70MB of cache, you'll have plenty of memory for multitasking, video editing, and more.
But what really sets the AMD Ryzen 9 3900X apart from the competition is its advanced features. With support for PCIe 4.0 and 3200MHz DDR4 memory, you can take full advantage of the latest and greatest technology. And with an unlocked multiplier, you can easily overclock the processor to even higher speeds, pushing your PC's performance to the absolute limit.
Installation is a breeze with the AMD Ryzen 9 3900X, thanks to its easy-to-follow instructions and included Wraith Prism LED cooler. The cooler is not only stylish, but also highly effective at keeping the processor cool, even under heavy loads.
Overall, I can't recommend the AMD Ryzen 9 3900X enough. If you're a PC enthusiast who demands the very best from your system, this processor is the way to go. With its blazing-fast speeds, advanced features, and easy installation, the AMD Ryzen 9 3900X is a true standout in the world of PC components. So why wait? Unleash your PC's full potential with the AMD Ryzen 9 3900X today!
I overclocked this Ryzen 9 3900x which I overclocked to 4.2ghz (able to go to 4.5 but haven't tested that out yet).
Just as with my last Ryzen 7 2700 that was overclocked for the 1.5 years I used it it has been incredibly stable. I do not use the wraith cooler, I have a dual chamber water cooler as these CPUs run a bit hotter than the Ryzen 7 (8 core) CPUs - of course I used a water cooler with that as well due to overclocking.
You could get away with the cooler and overclocking possibly but it is best just to use the water cooler just in case.
The processing power is incredibly. I have it coupled with a 2080ti and 32 gigs of 3200mhz ram. I do video editing, graphics, and sound editing for work. Heavy CPU and graphics card usage in those processes and this computer runs perfectly. I would stack this against any intel chip in the same range... this one beats it in speed and price.
In Ryzen Master software currently it is fluctuating between 36 degrees C, and 38.6 degrees. With my Ryzen 7 2700 which was overclocked to 4 ghz and with my other water cooler (single chamber) it was usually between 24-30 C. so we added 4 more cores, and more power per core. I have not noticed a significant increase while running games/software but the limit is 95 degrees C so it is not really something you need to worry about.
I highly recommend this CPU. This is expensive when looking at CPUs like the Ryzen 7 2700x and similar, but 430 dollars or whatever it was is well worth it. My old PC (which has been rebuilt and still has a GTX 1070) is still a modern PC that is capable of a lot and this current one will be for several years really. Short of upgrading the video card to the 3090 within the next year (maybe) I do not foresee any real need to upgrade the CPU for at least 3-4 years.
As far as money goes - sometimes we need to be reminded of perspective. My fiance was getting a laptop the other day and wanted to spend 500-650 max. She is a traveling medical worker. So a laptop will be very important to her and used a lot as she goes from city to city. So I explained that we drop upwards of 1000 dollars or more on our phones every 1 to 2 years without much thought at all. yet when we are buying electronics that will need to have a lot of power and hold up and be used as much or more we get very cheap. I spent 2000 dollars on a laptop back in 2012 and have upgraded it here and there (ram and hard drive) and it still runs extremely well. I use it for a lot of things. Had I spent 500 dollars it would have been useless by now.
So if you have the means, do not cheap out and buy a 300 dollar option for your CPU - you will end up spending that much or more very soon. Always buy beyond what you need when building a PC if it is doable for you. I have had systems that ran flawlessly for many years, and ones that played the latest games at high settings with decent FPS, and ran adobe software wonderfully.
I will update this review when I test an OC of 4.5 ghz and give you the details on cinebench for both the 4.2 and 4.5 OC.

Por una parte, tenemos el procesador Ryzen 3900X con 12 núcleos y 24 Hilos con frecuencia base de 3,8GHz y hasta 4,6GHz con socket AM4 y un TPD de 105w (Ojo que el consumo es bastante inferior, solo llega a ese extremo en renderizado y puntualmente)
Lo tengo instalado en una placa base MSI PRESTIGE X570 CREATION con 32GB de RAM DDR4 a 3600MHz (G. Skill Trident Z adecuada para estos Ryzen) con refrigeración líquida NZXT Kraken X42 y su temperatura es de 34-38°C en procesos normales, jugando no pasa de los 50°C y renderizando no pasa de los 65°C (Temperatura ambiente 21°C)
En relación con el disipador de serie (Probado pero reemplazado por refrigeración líquida que es más eficiente), es muy chulo, las luces RGB muy llamativas, buenas velocidades de ventilador para no meter mucho ruido (No es muy ruidoso a bajas temperaturas a altas es algo molesto)
En la parte inferior del disipador de serie en vez de ser plano totalmente tiene 3 ranuras, en principio es para una mejor refrigeración pero que con la pasta térmica no hacen el contacto adecuado que debería y es fácil echar más pasta térmica de la adecuada y terminar con la pasta en sitios que no debería
Existen termal-pad que te evita estos posibles problemas, pero por algún motivo en mi caso con la refrigeración líquida la temperatura es más alta que con la pasta térmica y eso de que es reutilizable en mi caso no ha sido así, ya que queda inservible (Hablo de 0,5 mm)
*Un factor determinante a la hora de comprar este procesador y no un i9 9900k o i9 10900k han sido las vulnerabilidades que siguen afectando a Intel y que, aunque alguna este parcheada por software o por hardware no me convencía su compra
Recomiendo este procesador porque es una pasada lo optimizado que va sobre todo para edición de video y para los más gamers para jugar, además su precio es muy bueno ahora
Eso si es muy importante tener un hardware equiparable a nuestro procesador, (Una buena fuente de alimentación es primordial)
* El consumo energético es bajo (Mi PC con todo suele consumir sobre 130-250W), dependiendo la carga de trabajo.
** Mucho cuidado al poner pasta térmica, si pones de más límpialo en el zócalo, no vaya a ser que lo retires y parte de esa pasta pase a los pines.
*** Ahora Ryzen saca la serie 5000, el equiparable al 3900X sería el 5900X, que si leemos las características y mejoras no lo veo una gran mejora, he tenido la opción de comprarlo, ya que socket y mi placa lo admite, pero por 200MHz no compensa. Además, pasa lo mismo con el 3900XT son 100MHz más. El 3900X me parece la mejor opción de compra además las BIOS ya está pulidas.
**** Se supone que este procesador su frecuencia base es de 3,8GHz y llega hasta 4,6GHz, yo usando el modo automático de MSI trabaja todos los núcleos a 4,2GHz, todo esto a una temperatura de 36°C (Sin carga de trabajo), ahora en renderización de video llega a 4,3GHz pero nunca ha superado esos 4,3GHz (A ver si con las nuevas BIOS mejora esto)

La CPU sorprende per l'elevato numero di core a disposizione, estremamente utili in produttività e in modalità "Creator", mentre per un uso estremamente gaming, direi leggermente over power e poco sfruttata. Nonostante il 3900x abbia più volte battuto in benchmark la controparte Intel (su alcuni bench come in quelli di WinRar), ci sono situazioni dove ancora l' i9-9900K risulta superiore. In gaming appunto, ma non solo. Molti giochi della precedente generazione non sembrano beneficiare dell'elevato numero di core, facendo piuttosto affidamento sul single thread. Rara eccezione per F1 2019 e 2020.
Comunque, dovete tenere a mente che ci sono ambiti in cui Intel Core i9-9900K (e superiori) risulta/no ancora imbattibili. Vecchi giochi che fanno affidamento sul single thread, come World of Warcraft, avranno prestazioni superiori su un processore Intel, nonostante il divario si stia assottigliando sempre di più. Parlando invece di giochi più recenti, vorrei citare il caso di Star Citizen, che per quanto sia ancora un'Alpha allo stato brado, sembra ignorare completamente la potenza di calcolo di questa CPU. Quindi, rimanendo in tema gaming le generazione attuale di videogiochi non sembra premiare il numero di core o la potenza intesa come un'insieme di fattori, piuttosto tende a considerare l'elevata frequenza. Motivi per cui ancora Intel può vantare un discreto vantaggio.
La vera differenza la si nota nei bench di decompressione e compressione, dove nelle prime posizioni la fanno da padrone le CPU di AMD con uno scarto anche considerevole. Ragionando in ottica futura, programmi e giochi potranno beneficiare maggiormente di questa potenza di calcolo, abbinata ovviamente a una configurazione hardware adeguata. O almeno questa è la speranza. Così come è altrettanto plausibile che le nuove GPU sgraveranno notevolmente il carico della CPU. Vi lascio la mia configurazione:
MSI x570 ACE
Corsair Vengeance 32 GB (2x8 gb) 3600 mhz
ASUS STRIX 1080 (ancora valida in Full HD)
PSU: Corsair 760W (80 plus)
Fondamentale il supporto a PCI Express 4.0.
Consiglio la sostituzione del bel dissipatore; ahimè discreto, migliore della precedente generazione, ma per CPU di questo calibro ci vuole un buon dissi ad aria oppure un liquido di buona fattura, non necessariamente con radiatore da 360 mm. Qualche consiglio per l'acquisto:
✅ ARCTIC Liquid Freezer II 360 (best-buy)
✅ DEEP COOL Castle 360 RGB (best-buy e ottima pompa)
✅ Fractal Design Celsius+ S36 (tra i migliori ma costoso)
✅ MSI MAG CoreLiquid 360R (buon rapporto qualità e prezzo)
✅ Corsair Serie Hydro H150i (prezzo elevato ma garanzia TOP)

Vengo de un i7 2600K@4.2ghz y la diferencia es muy grande, ffmpeg es entre 4-5 veces más rápido, en general todo es más rápido (hay que decir que también influye un salto en otros componente como la ram ddr4 y el almacenamiento nvme). Últimamente con el i7 había ciertas situaciones en las que al ordenador le costaba hacer varias cosas a la vez, incluso el navegador va lento, pero con el 3900x nada se atranca
Lo tengo en una placa MSI MAG B550 TOMAHAWK con dos módulos crucial de 16gb, 32gb en total, 3600mhz@cl16. Esta placa viene con el "PBO" activado por defecto, cosa que al principio me dio problemas cuando le daba caña al 3900x, es decir, ejecutando ffmpeg codificando solo video, a los 3-5 minutos se reiniciaba, y no por calor, en en la prueba de estrés mprime/prime95 small fft en vez de calentarse lo que hace es bajar el reloj por debajo de los 3800mhz!?, que la opción de overclock de AMD haga underclock... madre mía. Después de probar las diferentes opciones de overclock me decante por OC manual de CCX y lo he conseguido poner a 4275, 4225, 4100, 4100 @1.187v, que creo esta bastante bien, no le doy más caña, porqué con un disipador neptwin v2 y ejecutando mprime small ftt se pone un poco por encima de los 90C, aunque no creo que haya otra prueba que lo estrese tanto, codificando en ffmpeg, libx264, solo video, se pone un poco por encima de los 70C, en reposo queda por debajo de los 40C y haciendo tareas ligeras como mucho sube a 45-50C
Volviendo a porqué un 3900x y no un 5800x, con las tarjetas gráficas que ""hay"" en el mercado, el cuello de botella es siempre la tarjeta, exceptuando las tarjetas tope de gama, teniendo en cuenta que ahora mismo adquirir una tarjeta gráfica es imposible, sea tope de gama o no. Me he tenido que conformar con una Radeon R9 Fury que tenia de antes, es imposible comprar una tarjeta gráfica a un preció decente.
En general suelo usar la "potencia del ordenador" mayormente para reproducir video a x50, con el i7 solo podía hacer x8-x20 como mucho (depende de la resolución y fps del video), es una buena-rápida manera de ver si un video tiene errores mirando los logs del mpv. Y he ido acumulando una gran reserva de videos que están pendientes de re-codificar.
Extras:
Haciendo streaming con el OBS 1080p@60fps, x264, preset fast, la barra de estado pone que usa 10-20% de la cpu
Otro de los motivos por los que compre un procesador tan "potente" fue porqué hay varios programas que tienen la opción de usar la aceleración por hardware de tarjetas gráficas, pero esta opción suele dar problemas, así que ahora puedo desactivar esta opción ahorrándome cuelgues en navegadores, problemas con los reproductores de video... y todo esto es rendimiento extra para la tarjeta gráfica
Añadir que he aprovechado para hacer el salto de windows a linux, la placa, procesador y ram han funcionado sin problemas y los drivers de la tarjeta gráfica son fáciles de instalar. En linux los problemas son encontrar alternativas de software y cosas pequeñas que quieres tener como en windows y tienes que adaptarte...
Gigabyte GeForce GT 710, todo dentro de una caja COOLERMASTER EATX MASTERBOX 5 Black Edition con 4 ventiladores EZDIY-FAB PWM 120 mm. He utilizado el ventilador Wraith Prism de serie que venia con la CPU porque no voy a hacer overclocking.
El ESXi v6.7u3 se ha instalado sin ningún problema y ha reconocido todo el hardware. Además también tengo habilitadas las funciones para el i/o passthrough devices (por ejemplo, si quiero puedo asignar la tarjeta gráfica a una VM).
Ya se que al utilizar un procesador y placa base de gama consumer (no es ni workstation ni server) pierdo funciones como el control remoto iLO/IPMI, o la posibilidad de monitorizar el hardware (temperaturas, ventiladores, etc.) desde el ESXi. Sin embargo, por el coste total (unos 1600€) tengo una bestia de equipo con componentes garantizados para muchos años. Si quiero más fiabilidad puedo simplemente montar un segundo equipo de backup (por ejemplo con un Ryzen 7 3700X para reducir costes) y me sale todo muy barato.
Con los nuevos Ryzen 7 y Ryzen 9 ya no hace falta irse a la gama de procesadores para servidores y pagar una fortuna para tener un servidor potente.
