The guys over at Wccftech have leaked the lineup of upcoming Ryzen 9 CPUs featuring models names and specifications including core/thread count, base frequency and even TDP. Nevertheless, as for now it remains unknown when AMD is going to release these new processors.


Like with Ryzen 7, the different Ryzen 9 Threadripper processors can be distinguished by a tailing "X", which stands for XFR technology. AMD's Ryzen 9 Threadripper CPU lineup includes two 16-core CPUs, three 14-core chips, two 12-core processors and two 10-core CPUs. The pack is led by the AMD Ryzen 9 1998X and the Ryzen 9 1998 processors. The base clock frequency ranges from 3.2 GHz to 3.5 GHz and the Ryzen 9 1998X features XFR technology. According to Wccftech, the TDP of this new 16-core CPUs is set to 155W.

There are also three 14-core CPUs: the Ryzen 9 1977X, the 9 1977 and the 9 1976X. Clock speeds of these CPUs range between 3.20 and 3.60 GHz. All SKUs feature SMT, enabling 28 logical CPUs. The performance of the new 14-core models should be comparable to Intel’s Core i9 Skylake-X processors. Furthermore there are two 12-core CPUs and their clock speeds range between 3.00 and 3.20 GHz with a TDP of 125W.

Last but not least there are two 10-core processors with a base clock between 3.10 and 3.60 GHz. Like the 12-core processors, these feature a TDP of 125W. All upcoming AMD Threadripper chips will come with a quad channel DDR4 memory interface.

The table below will give you a quick overview regarding all the details:

Processor	Cores	Threads	Base Clock	TDP
Ryzen 9 1998X	16	32	3.5 - 3.9 GHz	155 W
Ryzen 9 1998	16	32	3.2 - 3.6 GHz	155 W
Ryzen 9 1977X	14	28	3.5 - 4.0 GHz	140 W
Ryzen 9 1977	14	28	3.2 - 3.7 GHz	140 W
Ryzen 9 1976X	14	28	3.6 - 4.1 GHz	140 W
Ryzen 9 1956X	12	24	3.2 - 3.8 GHz	125 W
Ryzen 9 1956	12	24	3.0 - 3.7 GHz	125 W
Ryzen 9 1955X	10	20	3.6 - 4.0 GHz	125 W
Ryzen 9 1955	10	20	3.1 - 3.7 GHz	125 W
