3rd Gen AMD Threadripper Tech + Performance Preview!

Before the official launch of the 3rd Gen Ryzen Threadripper processors, AMD gave us a tech and performance preview of what they will soon be unveiling…

Here is EVERYTHING we know so far about the 3rd Gen Ryzen Threadripper processors!

3rd Gen AMD Ryzen Threadripper Tech Preview!

 

The 3rd Gen AMD Ryzen Threadripper Tech Preview

Giving us a preview of the 3rd Gen AMD Ryzen Threadripper processors is Don Woligroski, AMD Desktop Processor Technical Marketing Manager.

And here we have the official 3rd Gen AMD Ryzen Threadripper performance preview featuring Dr. Lisa Su, Robert Hallock and James Knight from AMD, as well as Dan Akers and Shawn Wallbridge of Blur Studio.

 

The 3rd Gen AMD Ryzen Threadripper Processors

The first two members of the 3rd Gen AMD Ryzen Threadripper processors have been confirmed :

  • Ryzen Threadripper 3970X : 32C / 64T, 4.5GHz / 3.7GHz, 144 MB cache
  • Ryzen Threadripper 3960X : 24C / 48T, 4.5GHz / 3.8GHz, 140 MB cache

Like the 3rd Gen AMD Ryzen processors, the 3rd Gen AMD Ryzen Threadripper processors are based on the new Zen 2 architecture with the chiplet design approach.

The CPU dies are fabricated on the 7 nm process technology, while the I/O die is fabricated on the 12 nm process technology.

New Socket sTRX4 + AMD TRX40 Chipset

AMD also announced that they are breaking backward compatibility with the 3rd Gen AMD Ryzen Threadripper.

They are introducing both a new sTRX4 processor socket, and a new AMD TRX40 chipset to support it. However, you will still be able to use existing Threadripper coolers.

The processor comes with 64 PCIe 4.0 lanes, of which 56 are available for use. The AMD TRX40 chipset adds another 24 PCIe 4.0 lanes, with 16 free lanes.

In total, the new Socket sTRX4 and TRX40 chipset will give you 72 free PCIe 4.0 lanes to use, compared to just 56 free PCIe 3.0 lanes in previous generations.

In addition, the new AMD TRX40 chipset communicates with the 3rd Gen Threadripper using a PCIe 4.0 x8 link. This gives it 4X more bandwidth than the PCIe 3.0 x4 link used in the first two generations.

3rd Gen AMD Ryzen Threadripper Price + Availability

The AMD Ryzen Threadripper 3970X is priced at $1999, which is $200 more than the Threadripper 2990WX when it was launched.

The AMD Ryzen Threadripper 3960X, on the other hand, is priced at $1399 – $100 more than the Threadripper 2970WX when it was launched.

AMD will officially launch the 3970X and 3960X on 25 November 2019, and from the performance preview video, it looks like both models will be available on the same day!
