The Most Powerful Desktop Processor in the World ! What more can be said ?

Reviewed in the United States on May 14, 2020

Style: AMD Ryzen Threadripper 3990XVerified Purchase

I recently finished my latest Workstation build with this processor. I'm 65, a retired Aerospace Engineer and I still like to do a lot of CAD design and Rendering for my hobby now. This processor is INSANE Fast ! I have been using workstations in Aerospace for the last 40 years or so. Mostly high end, very expensive UNIX boxes. But I have never seen a processor the likes of this. Expensive? YES. But if you want the best in the world you pay the price. I can't believe anyone would ever be disappointed with the AMD Threadripper 3990x as the heart of their Workstation. This processor actually has an overclocking algorithm built in called "Precision Boost Overdrive" that lets you extend the boost clock to 4.5GHz. You just set it and forget it. I have never had a crash with PBO +200MHz enabled.

Do not buy it for anything that can fully utilize 128 treads.

Reviewed in the United States on March 13, 2020

Style: AMD Ryzen Threadripper 3990XVerified Purchase

As others said this is a beast of a CPU. However almost every "shrink-wrapped" user (not server) application out there is not designed to run on this level of hardware. I believe there are three type of apps where it justified: 1. Blender and similar apps, 2. Some server class applications (keep in mind that it is not a real server CPU, that is Epic, 3. The most important one - if you professionally develop software that will eat all available cores with almost linear scalability. That is my case, My algorithms need as many cores as possible, fastest random IO access to storage (read Intel Optane) and as much RAM as possible. The only downside for me is limitation of 256GB of RAM on 4 channels. Because of this I will probably switch to dual Epic system, If I can justify the cost.

Disappointed to see it does not support RDIMMs

Reviewed in the United States on February 21, 2020

Style: AMD Ryzen Threadripper 3990XVerified Purchase

I bought the processor to expect to use it as a test field for my software. I bought 8 x 32GB ECC RDIMMs then found out that it was not even been supported. Now I have to return the RAMs. It is also hard to find ECC UDIMMs in this size.
Note that for Linux installation, you also need to upgrade BIOS or the installer will be stuck after GRUB selection

Performance? Yes. Value? No.

Reviewed in the United States on February 17, 2020

Style: AMD Ryzen Threadripper 3990X

Simply put, this is the most performant HEDT processor in the market space right now. While it is true that few people need this, those that do are also the ones that can afford it. Value wise, its not as clear, versus AMD itself and Intel's flagships.

Something interesting is happening to the CPU space when it comes to online opinion and reviews. While it is true that AMD tech has improved dramatically over the past five years, the online "fan" reaction is much more extreme. In the case of the 3990x, what is most notable is the absence of a value discussion in many online reviews. Its simply performance, performance, and then performance.

Businesses deploying these in depth will have different decisions than consumers. These are NOT chips for big iron running net infrastructure. As far as the individual HEDT enthusiast, pricing the 3990x against AMDs own offerings, and Intel's 7/9/10 980XE line, the 7980XE is a surprisingly strong value position against 3990X.

If you have the money or the need, simply buy this, no questions asked. If you a really looking to build a home render engine at the lowest price point per performance index, then spend several hours reading in-depth online reviews written by tech experts. Ignore the online enthusiast community and Youtube, as they will always emphasize performance.

EDIT: I love the comments that triumphantly declare that cheaper SKUs in the AMD line compare more favorably against 7980XE or other Intel parts. Of course they do, but this review is for a 3990wx, isn't it? Its entirely about how the two chips scale in the higher core performance niche. And for those red-ensconced AMD zealots hoping to sniff out an Intel partisan, keep looking. I have several of the TR2/4 class HEDT chips in my stable and am happy with them. Not enough? Intel's upgrades to the 7980xe remain poor values when a three year old chip can still out-perform them due to an expanded thermal envelope. Peace to all, have fun with your PCs.

Best CPU I have had - no need for overclocking!

Reviewed in the United Kingdom on July 1, 2020

Style: AMD Ryzen Threadripper 3990XVerified Purchase

I am writing this review not to tell you how impressed I am by the fact that one can actually have 64 cores / 128 threads in one CPU die twice as cheap as the competition and do it gracefully, not overheating or anything like that (well, excuse my Kaby Lake that started overheating after running full load for a couple of days). I am writing to point out that one does not need to try to overclock the new generation AMD CPU's because modern motherboards compete by *safely* overclocking modern CPU's in their default mode, even in the energy saving 'ECO' mode that is!

After installing my Ryzen Threadripper (3990x) I was certainly cautious whether the AIO cooling solution provided by the dedicated Corsair MasterLiquid ML360R special edition for 3990x would be adequate for this powerful CPU running at full load 24/7. So I was running test after test with different load patterns (16/32/64/96/128 threads) as well as different fan settings, with the aim of finding an elusive "sweet spot" for the 'just right cooling at minimal noise' from the fans.Eventually I also tried to overclock the CPU moderately (up to 3.6 GHz) and see how the CPU die temperature and the noise from all the fans (6 in total) would interplay. I should say, I was pretty much amazed at the result! It appeared that at default ECO settings the BIOS (i.e. the motherboard) acted like both a very efficient overclocking wizard (behind the scene; many people would not notice even) but also as a shield for the CPU not to overheat while still providing just the correct level of power for any particular load. To my big surprise(!), if I wanted to overclock manually by setting the CPU frequency precisely, I would definitely go into a dangerous regime of uncontrolled (over-) heating, albeit masked by the time it would require to manifest, depending on the frequency I opted for - the higher the frequency the shorter the time.

Long story made short, If you try to overclock such a powerful CPU, beware that the BIOS will (unduly!) maintain precisely the preset frequency that you chose in the BIOS settings, no matter what - that is, irrespective of the actual load, i.e. in the idle state too! This is an easy way to unduly overheat and, by doing so, ware out the CPU beyond its actual capacity (like a battery that is never given a chance to properly recharge in full). On the contrary, if you leave it to the BIOS (motherboard) to decide on the overclocking regime depending on the actual load (by opting for the default settings), you will (a) prolong the CPU life (while staying under warranty!), (b) will be using exactly the power needed for the load at the time, (c) save some quid/dollar on your electricity bill as the wattage spent will be exactly proportional to the load your CPU (and PC) is using (i.e. the over- or under- clocking done by the motherboard). As an extra bonus, your ears (and perhaps the climate in your family) will be healthier! :)

That's all I wanted share, based on my extensive tests for over two weeks of running this CPU under different loads and cooling. About the cooling regime, by the way, if you don't definitely overclock beyond what is necessary for your tasks (well, games for some), you will find that no special regime is required, just auto-tune your fans and maybe you will be able even to reduce the primary CPU (Corsair in my case) fans to run at lower speeds most of the time, unless the CPU die T goes over 70 C.

Die Definition von Leistung

Reviewed in Germany on March 22, 2020

Style: AMD Ryzen Threadripper 3990XVerified Purchase

Für reine Spieleenthusiasten sicher der falsche Prozessor, für jene, die wissen, warum sie das diesen Batzen Geld auf den Tisch legen ein Segen. Rechenleistung zum umfallen, sowohl im Multi, als auch im Single Thread, lange habe ich keinen so leistungsstarken, nud doch so ausgewogenen Prozessor im HEDT bereich mehr gesehen! Bisher hatte man die Wahl, wer Kerne brauchte musste AMD Kaufen, dafür aber wo diese nicht zählten deutliche Abstriche machen, wer das nicht voll auskosten konnte war mit Intel besser aufgehoben, Mit Zen2 offensichtlich kein problem mehr... Die CPU zieht bei mir mit aufgehobenem Power Limit(Voreinstellung Mainboard) im Single thread mit einem 9900 KS gleich, im multi gibt es wohl aktuell nichts, was auch nur annährend an dieses Monster herankommt... Noch nie habe ich so kurz auf Renderergebnisse gewartet, und die abstriche, die man beim Gaming bei Vorgängern machen musste sind dahin, volles Lob an AMD hierfür!

Ein Traum für Heavy-Workload Cases / 3D Rendering

Reviewed in Germany on June 5, 2020

Style: AMD Ryzen Threadripper 3990XVerified Purchase

Sicher die CPU ist teuer, sehr teuer, aber für den Preis bekommt man nirgends mehr geboten. Für User welche damit primär spielen möchten oder Videoschnitt/Grafikbearbeitung betreiben ist diese CPU nichts. Sicher, die Leistung stimmt, aber die CPU langweilt sich und der Preis wäre dafür doch viel zu hoch. Für solche Zwecke zu Ryzen 3950x oder Threadripper 3960x bzw. 3970x greifen.

Ich selber nutze die CPU beruflich für Simulationen und Rendering (3Ds Max, Cinema 4D, Maya, Blender) und da kann die CPU ihre Stärken ausspielen. 64 Kerne mit 128 Threads bieten einen in diesen Einsatzbereich nie dagewesene Leistung zu "annehmbaren" Kosten.
