Should Serve Me Many Years
Way more processor than I typically need. I do like to run lots of screens and have many apps/windows open, and this CPU should last me for many years. My motherboard and accompanying software set things up automatically with a modest 12% OC to all 12 cores. This default configuration is keeping all the cores locked at 4.275mhz. From what I can tell in using the machine it runs pretty cool/quiet for a configuration that is keeping everything running full speed at all times. Each core seems to be pulling from 11 to 14 watts of power depending on the load. My cooling is nothing fancy, just a cheap 240 type AIO kit (had it laying around so might as well use it) in a spacey/airy industrial style rack-mount chassis. No problems keeping temps below 50c in a room kept around 70f. I do use this build for DAW applications. Dorico, Cubase, Finale, and Sibelius are my goto apps in that arena. The sounds and effects I use aren't that CPU intensive, but they can work a storage device pretty hard. I run consumer grade storage devices (no Thunderbolt, SCS, or anything like that) on NVMe or SATA with the controllers built into my X570 motherboard. I don't do benchmarks and stuff, but the machine feels very snappy/responsive with any task I throw at it so I'm very pleased. On value, I think it really depends on what one needs, and when one is buying. I got mine in the thick of the holiday season shortly before a new generation would be released. I needed it NOW and didn't really have time to wait for the best timing or shop around. For me, there are probably better values out there for my specific needs in the lower ranges or older models, but I guess it never hurts to have some growing/future proofing room. For what I do...this processor should serve me for at least a good 10 years! As long as I don't go back and second guess myself, compare the finer points on value of other models and makes....well, I won't miss any sleep. I'll just enjoy my snappy PC and be happy.

Smooth as Silk. PowerFull +12-16 FPS Game Cache!
For me , a Gamer, The 64mb of Game Cache was important and being ably to run up to 4600mhz oc memory speeds! (MY MOBO), Besides that, There is no Flaws, Besides it does run a lil Hot under Load, Thats depending on your case Setup of course, But not to Worry, for any one that might, because the normal temps for these are 75c up to 90c. If you Want to OverClock you of course can but will Have to have a WaterCooler, unless you have decent air flow with Minimal OC settings. I came from a Ryzen 7 Seriers From the 5 Series also, So i know what all these cpus can and cant do. Really no reason to OC though. Unless like myself , Stream CoD WarZone in 1440p While Running Game in 1440p Pretty Much Everything MAXED With RayTracing on. and Get a average of 150- up to 200FPS . While streaming its only a 2-4 FPS drop, with of course some unseen Latency Draws, Ryzen 5 i averaged 80-110FPS Ryzen 7 100-130 FPS MY SPECS.

Great CPU for Gaming/Fast Workstation
This CPU is one of the top of the line, latest and greatest CPU's. It will run anything that is thrown at it, and compared to Intel, the price is much more friendly. They recommend a water cooler, however, I am using a Noctua NH-D15 cooler in the single fan configuration (dual fans wouldn't fit as my RAM is too tall) - and it keeps the CPU below 60°C during idle and playing games. I have yet to run anything that even pushes the maximum power out of this CPU. I would definitely recommend this as an upgrade, and even for new PC builds. Just be aware that this requires a discreet (separate) graphics card, as there are no integrated graphics. If you have an issue with a BIOS update - AMD will send you a "bootkit" loaner for free, which will allow you to update your BIOS and install your new CPU.

Best AMD chip for overclocking (besides the 3950X)
Great chip if you’re not looking to dish out the extra cash for the 3950X. I would not recommend this to users who are not planning on overclocking. The XT series is designed for max OC potential, so don’t spend the extra $$$ if you’re going to run things at stock. I have a custom loop with 2X 360mm rads + 1 480mm Rad, and Im running it at 4.3 GHz on all cores. Idle temps are 40-50 C , with cinebench temps jump to About 68-70 C and during gaming it usually stays at around 60-65 (all testing done @ 1440p). You will definitely need a solid cooling solution for this processor. I’m not sure if I’ll consider undervolting to lower temps as it runs pretty hot even when watercooled, however I’m happy with the performance.

super speedy and great for gaming
My i7-4790k wasn't cutting it. I would run at 100% on games and video editing. It was time for a new CPU. So I looked around, and since my son has the R7 2700x and was pleased with it, I decided to go with Ryzen. But I wanted something that I could throw anything at and handle it with ease. I saw the new R9 3900xt, which has a small boost up from the 3900x. So now I have my computer running and WOW, I've been missing a lot. On Minecraft, chunks load a lot faster, not at a snail pace. Need for Speed is great. getting huge fps. With the i7, the game would run the cpu at 100%. This R9 is barely using 7% of it's weight in running NFS. Let's not forget about downloads. This thing is quick. The i7 would take forever. go get snack and take a nap and it's still downloading. But R9, blink your eyes and it's done.

This was an upgrade from the 2700X, so that's my basis for comparison (being as the rest of the system is identical). I picked up the XT variant, but how much difference there is between the X & XT is debatable. In terms of power draw, it beats the 2700X handily, with a stable all-core overclock of 4.350GHz at ~1.34v, whereas the 2700X required closer to 1.41v for the same clockspeed. Interestingly both the 2700X & 3900XT have similar top frequencies, at least that's my experience so far. The 3900XT runs much, much hotter than the 2700X, and that's even with a very substantial custom loop (360×30, 240×45 & 360×80 rads). Idle temp is low 40s, under load it can easily jump to the low 80s. The 2700X was ~10°C lower across the board. Whether this is something to do with AMD changing how the temperature is reported (that is pure speculation on my part) or some other issue I'm not sure. Online I found many users had similar experiences vis-a-vis the higher temps. But it's still within spec, so I would just say make sure you have a decent cooling solution. Overall though I'm pleased with it. How much difference users notice depends greatly on what you're upgrading from, and what you're using your system to run. If you're currently using an 8 core Ryzen processor (any generation) and are using your system mostly or exclusively for gaming, I might hold off until prices come down, because the difference you'll notice will probably be fairly modest. Which for $600 or $700 is not a very good ROI.

Sensational chip. Upgraded from a ryzen 7 1700x. Flight sim 2020 frame rates went from 19 to 45 with my 1080ti.

If you need to build a home server/development PC, this is a great deal. I bought for my development/gaming PC. I guess got lucky to get a good bin. It easily boosts to 4.4 to 4.5 at 83 to 84 Celsius(single core)using an air cooler (hyper 212 black edition, case is deep cool Matrexx 50 air flow). Cinebench R23 gives me all core 4.2 GHz, PBO on, on the ASUS TUF x570 Plus WiFi(TIP do not update to BIOS 3001, it has some nasty bugs with Zen 2 processors). There are plenty of websites that have the Pro's and Con's for this processor, not going to delve into this. Advice is to get a good board with a Decent VRM's and get a good cooler to get good performance. If you are in no hurry to build a PC, I suggest you wait for price drops, when Zen 3 starts to become more available or when Intel Rocket lake releases early next year. Do not play many Games on this but if you do then I suggest to get the Zen 3 models.

Nuevos procesadores AMD introducidos en el segundo trimestre de 2020. Es más potente que 3900X y permanece cerca de 3950X. Aunque la calidad / precio es más cara que la 3900X, la calidad / precio también es alta. Comparado con el Intel i9 de décima generación, me sabe mejor. Este es un propósito más general, si quieres jugar mientras juegas, es mejor que Intel i9. Si solo quiere jugar pero no quiere grabar juegos o transmisiones en vivo, compre el i9 de décima generación (la novena generación es peor). Para el renderizado de fotos y videos en 4K me va genial, lo mueve todo con mucha facilidad. He de decir que lo tengo montado con refrigeración líquida para bajarle un poco la temperatura porque lo he overcrackeado.
