Hi, We are UNIKO’s hardware!
The much-awaited 16c/32t Chipzilla, the Ryzen 9 3950X, is finally being released. This processor is the AM4 platform’s “Ace in the hole” against Intel’s HEDT X299 platform. Let’s take this chip through our test suite to see how powerful it truly is.

Like its predecessor, Zen2 is using the glue method to add cores. However, the core Chiplet and IO DIE are glued independently this time. As indicated in this diagram, the left one is the IO DIE, and the right ones are the CPU cores. The CPU cores are divided into two groups of CCD (core chiplet die). Each group of CCD is composed of 8 cores which form 2 CCXs (1 CCX is a 4 core grouping inside a CCD). In resume, the R9 3950X does indeed have 16 cores as this diagram indicates.
If we take a look at the previous Zen1 architecture, the latency inside the CCX should be fairly low. But, once it tries to communicate with other CCX clusters like what Threadripper ( Zen1 architecture) did with the first CCX cluster to the third or fourth CCX cluster – the latency becomes exponentially higher.
As an example, the latency between the Ryzen 7 1700’s CCXs as high as 120 ~130ns.
As for when the 1st generation Threadripper first CCX cluster tries to link up with the third or fourth cluster, the latency will drastically increase to 230ns!
Since the Ryzen 9 3950X have numerous cores and threads, we have only taken some reference points to make our observations:
- The latency inside a CCX has been greatly decreased (~26ns) compared to Zen1’s 40ns.
- The latency between CCXs for Zen2, in this particular case – the 3950X, has dropped to 66ns compared to Zen1’s loathsome 120ns.
- These results show that the latency between CCDs is comparable to those between CCXs or even lower in some cases. Thus, the mainstream belief that the separation of the IO DIE from the core Chiplet would cause a much higher level latency is proven to be incorrect.
In summary, these same results can also be replicated by the new Zen2 Threadripper. We cannot praise AMD enough to have made such massive improvements in reducing the latency between the different CCDs.
When AMD first launched its Ryzen 1000 series back in 2017, which their flagship R7 models featured up to 8 cores, it completely changed the landscape of the consumer CPU market. At that time, Intel has saturated the market with their 4 core processor releases one after another. However, AMD has changed the game rules by bumping up the mainstream CPU core count from 4 to 8.
In early 2019, AMD released its new Zen2 processors which they used TSMC’s new 7nm manufacturing process. They managed to bump up the core count even higher from 8 to 12 in only 2 years.
Even with their competitor Intel behind them in terms of core counts, AMD continues to push the limits of delivering more cores on a consumer chip.
Enter the Ryzen 9 3950X. This is AMD’s 16 core/ 32 threads crown-jewel for the mainstream AM4 platform. It nukes everything the competition has to offer at its price point.
On the other hand, Zen2 provides even better performance for the HEDT Threadripper platform in which we see the first 24 core and 36 core processors. We are also seeing the first deployment of PCIe 4.0 on both mainstream and HEDT platform, a much more expansive IO, and better power efficiency, etc… All these changes revolutionize the PC market for the better. What can we say other than AMD YES!
