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. ... show more

    • Do not buy it for anything that can fully utilize 128 treads.
Style: AMD Ryzen Threadripper 3990X
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. ... show more

    • Disappointed to see it does not support RDIMMs
Style: AMD Ryzen Threadripper 3990X
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 ... show more

    • Best performance and best value per core, by far!
Style: AMD Ryzen Threadripper 3990X
Please don’t listen to the people telling you the “value” is not here, pointing to Intel 7980XE. That’s an 18-core for $1900. Where’s the value? At that price per core this AMD would cost $6,755. If you want cheap the Ryzen 9 3950X is 16-core for $699. But, Intel also loves to skew the benchmarks and focus on any single obscure point in which Intel is better. The fan response is based on real world use when people realized the new AMD’s absolutely destroy the Intel CPUs in real world and gaming performance, at $ for $. Sure an 18-core i9 might slightly beat a 16-core Ryzen, but not by double, which is the price difference. Even if an AMD core was half the performance of Intel this CPU would be worth the price. Intel high core count CPUs are over $100/core, go check, do the math. What’s this 64-core??? Just over $50/core? Yes, it’s expensive but it’s 64 cores.... 16x the average Intel 4-core CPU, but not 16x the price. So, while everyone agrees that this is best in terms of performance I am here to say it’s best in value, too. You just have sticker shock over the number of cores. But, go back down to 32-core then, it’ll ease the blow at half the CPUs. ... show more
