AMD Threadripper processors reach 4.2GHz with xfr boost

AMD has announced that the three new Threadripper processors can achieve an xfr speed of 4.2GHz. The amount of L3 cache in the 12- and 16-core models is now also known: They have 32MB.

The xfr speed is mentioned by various sources such as TechPowerUp and TechReport. AMD indicates that the company uses the best three percent of the Ryzen dies for its Threadripper processors. The clock speed is remarkable, as all existing Ryzen processors can achieve an xfr speed of 4.1GHz and overclockers often fail to run the processors stably at a clock speed above 4GHz.

The fact that the Threadripper processors have 32MB of L3 cache is less special. After all, the processors consist of two active Ryzen dies, which have 16MB each. Including the L2 cache, the 16-core 1950X processor has 40MB of cache and the 12-core 1920X has 38MB. The amount of cache in the 1900X with eight cores has not yet been disclosed.

The Threadripper processors can overclock to 4GHz at the normal turbo speed with up to two cores per die. However, with the xfr technology, these processors can achieve a higher speed, provided the cooling is sufficient. With Ryzen processors, all cores are overclocked. It is not known whether this is also the case with the Threadripper chips.

AMD announced the prices and delivery dates of the Threadripper chips in July. The flagship model, the 1950X, has a suggested retail price of $999 and will be available August 10, along with the 1920X, with a suggested retail price of $799. The 1900X will cost $549 and will hit shelves August 31.
