AMD Announces Ryzen Threadripper 1900X

Today AMD rolls out what is not a very well kept secret, the Ryzen Threadripper model 1900X CPU. There is no doubt that Threadripper has already been a success for AMD, but how exactly does does an 8-core Threadripper fit into High End Desktop (HEDT) world of processors and platforms? The user profile is fairly skinny.

AMD Ryzen Threadripper 1900X

Let's start out with the bad news. AMD has not sampled HardOCP (Or any other review sites to my knowledge.) a Threadripper 1900X to test for you here today. Why? I am not sure, but that is the way it is. In all honesty, I have never seen one first hand, but AMD does suggest the 1900X processors do in fact exist. Quite frankly, the Threadripper 1900X performance as a CPU is not really what the 1900X is about. We already know damn well where it is going to come in, in the benchmarks. We have yet another Ryzen architecture CPU with 8-cores, very much like the Ryzen 7 series.

However, instead of having a single 8-core processor, we have two 4-core processors down underneath the Threadripper Integrated Heat Spreader (IHS). Yes, going from one Ryzen die to two is going to give us some situations with latency in the Infinity Fabric, so that the Ryzen 7 and 1900X do not exactly look the same in benchmarks, however they will not be far apart either.

While we have all the 1900X presentation slides below, these are the two you need to see in order to bring yourself up to speed with the 1900X, for more importantly the X399 platform.

Here is why AMD did not sample the 1900X for review. There is nothing truly exciting on the CPU-side of things. There is nothing here we have not seen before from AMD very recently. The Threadripper 1900X CPU relinquishes itself from the spotlight in order to let the X399 HEDT platform be the star this time around.

For the first slide above, the Ryzen 7 1800X is used as the baseline. Actually you could use any Ryzen 7 CPU as the baseline for this graphic. The 1900X is quite simply a "Ryzen 7" with all the goodness that the X399 platform has to offer, and there is a lot of goodness. Most importantly you get quad-channel DDR4, 64 lanes of PCIe direct to the CPU, and the promise of bootable NVMe RAID in a month. You already most likely know if these things "turn you on" or not.

Quite frankly, the Ryzen 7 dual-channel memory controller is already extremely robust. Quad-channel however will certainly give you the ability to add-on four extra sticks of less expensive RAM that will allow you to grow into a much bigger memory footprint over time or immediately. The 64 PCIe lanes and the promise of bootable NVMe RAID to put into those lanes you will likely find exciting too. You could easily lay down two 512GB NVMe SSDs and have one of the fastest, if not the fastest desktop system on your block, or state depending on where you live, in terms of IO.

The next slide above lays out how the entire Ryzen line stacks up. The 1900X will save you $450 or $250 over the 1950X or 1920X respectively. It all truly comes down to what you need and where your budget lies. X399 platform motherboards are not inexpensive, however you can quickly get into the sub-$350 range, but then you might be giving up some of the features, like multiple M.2 support, which is likely going to be one of the things you want.

The Bottom Line

The Threadripper 1900X is a very specific CPU for a very specific person that knows exactly what he wants, but more importantly, exactly what he does not want.

Of course, keeping in mind that Threadripper dies have been culled by AMD to be the "top 5% of Ryzen cores," surely suggests that we find some great overclocking with less cooling needed than what the 1950X needs.

We look forward to reporting on exactly that as soon as we can.


The full AMD presentation is shared with your below. I is worth a look through for sure, but hopefully we have filled you in from an enthusiast point of view. At least as good of a view as we can since we don't have the 1900X CPU in hand. There are some slides below that cover some very specific usage models, but when it comes to it being a "rendering powerhouse," or a "deep learning machine," I would suggest that saving $500 on half the cores of a 1950X would not be the move you would make. However the "video streaming professionals" configuration does make sense, at least to me. A 1900X on the X399 platform would give you a lot of room to grow over a Ryzen 7 system on the X299 platform, but even for most of us, the 1900X solution is still going to be overkill.
