Threadripper will come in two different variants, comprising the flagship 16-core/32-thread 1950X and the 12-core/24-thread 1920X.
Here’s a table with an overview of the key specifications:
|Cores/Threads||Base/Boost clocks||PCIe 3.0 lanes||TDP||Price (USD)|
|Threadripper 1920X||12-core/24-thread||3.5GHz/ 4.0GHz||64||180W||$799|
Both CPUs will use AMD’s new 4,094-pin TR4 socket and its X399 chipset, and offer four channels of DDR4 memory. Unlike Intel, AMD isn’t using the number of PCIe 3.0 lanes to differentiate between the chips, and they will both provide 64 PCIe 3.0 lanes.
The Threadripper processors are essentially super-powered versions of the original Ryzen chips. AMD uses a four-core CPU Complex (CCX) as the basic building block for Ryzen, so Threadripper has four of these CCXs in each package, while the 8-core Ryzen 1800X has just two.
However, the most interesting takeaway from AMD’s announcement is probably their price. When compared to the 12- and 16-core Intel Core i9-7920X and Core i9-7960X, the Threadripper chips are US$400 and US$700 cheaper.
AMD’s Threadripper also has a core count and I/O bandwidth advantage when compared to similarly priced Intel Core X processors.
The Ryzen 5 and 7 processors shook up the market by undercutting Intel on price while offering very strong multi-threaded performance, and Threadripper looks to continue that push.
That said, Intel maintains its lead in higher clock speeds and consequently better per-core performance, so Threadripper will probably measure up to Skylake-X in a similar fashion to how Ryzen compared to Kaby Lake.
This means that Threadripper will shine in workloads that can take advantage of its high number of cores and threads, while Skylake-X will look better on applications that prioritize single-threaded performance, such as gaming.
Threadripper will be available in early August.
In addition, AMD revealed specifications on its entry-level Ryzen 3 chips. The Ryzen 3 1300X will be a 4-core/4-thread part that clocks from 3.5GHz to 3.7GHz. The 4-core/4-thread Ryzen 3 1200 sits below that and runs from 3.1GHz to 3.4GHz.
Both Ryzen 3 CPUs will be available on 27 July.
