AMD launches Ryzen Threadripper 1900X CPU and more

AMD today introduces its new Ryzen Threadripper 1900X processor along with some other changes to the X399 platform such as NVMe RAID.

Introducing Threadripper 1900X

In the last month, we reviewed both the 1950X and the 1920X, both high core count CPUs with a lot of power and threads to dominate any professional workload they might encounter. What made them extremely attractive were their price points, expansive IO, and platform. Well, today we meet the third Threadripper CPU, the 1900X, which is an 8-core 16-thread part.


AMD's X399 platform has just become significantly more affordable. With confirmed pricing of $549 USD SEP (suggested price), the 1900X is slightly more expensive than the 1800X, which chimes in with 8-cores and 16 threads as well, but they are not the same CPU. The 1900X also offers a 4.2GHz XFR, which is the highest for an 8-core AMD part. The CPU offers a 3.8GHz base clock and up to 4.0GHz boost clock.


So, why should you get a 1900X over an 1800X? Granted, both have the same core and thread count, but the 1900X offers everything the 1950X and 1920X offer in regards to memory density, type, and channel support, IO, and storage support, and support for other platform devices such as GPUs. It's also an easy way for you to get into the X399 TR4 socket platform, and you can upgrade down the road if you feel there is a need for more cores and threads.


Platform matters when it comes to how much the CPU can be utilized. People who need all task crunching threads also require more memory, support for more devices, and more and faster storage. Threadripper supports many more GPUs, up to 512GB per channel of addressable memory space (for a total of 2TB), quad channel memory, and support for many more high-speed M.2 drive and, in the future, NVMe RAID. All Threadripper CPUs, including the 1900X, are from the top 5% of Ryzen dies, and the 1900X is no exception. Also, the 1900X is not identical to the 1800X when it comes to what's under the IHS.


So, you are probably wondering, what does it look like under the die? Is it just one 4+4 die with three disabled? The answer is no; it's two-two Zepplin dies in a 4+0 and 4+0 configuration. So it's 4+0 ~~Infinity Fabric~~ 4+0, and that way you still get quad channel memory support and all the IO. Let's see what AMD says about its performance.
