AMD will be supplying new Wraith Ripper coolers designed by Coolermaster that will allow the Threadripper 2990X to hit 4 GHz on all 32 cores on air. This was demonstrated during an AMD event recently held in Maranello, Italy. Getting all 32-cores to boost to 4 GHz on air is a commendable feat, which implies much higher boosts on single and fewer cores.

The upcoming AMD Threadripper 2990X is a 32-core 64-thread beast of a chip that offers a 3 GHz base clock and 4.2 GHz turbo clock on single core. A recently demonstrated benchmark showed that the Threadripper 2990X can boost up to 4.12 GHz on all cores with a capable water cooling setup. The good news is that those who prefer using the CPU with the stock cooler need not fear losing out on higher clocks. AMD is bundling the Wraith Ripper cooler designed by Coolermaster along with the Threadripper 2990X. What's so special about this cooler, you ask? The Wraith Ripper enables the Threadripper to boost up to 4 GHz on all 32 cores without any additional setup.

Yes, all 32 cores at 4 GHz! Obviously, single core and fewer core boosts can be even higher. The Wraith Ripper was recently demonstrated by AMD during a Threadripper 2 event in Maranello, Italy. Getting all 32 cores to perform at 4 GHz on air cooling is not an easy task so props to AMD for pulling it off. The icing on the cake is that, with this setup, the Threadripper 2990X scored 6000 points in Cinebench or so they say. This reminds us of the trouble Intel had to undergo during the 28-core HEDT CPU demonstration at Computex 2018 wherein it showed the CPU hitting 5 GHz on all cores. Only later was it revealed that Intel had neatly concealed the fact that it had pre-overclocked the chip and used a Hailea liquid cooler to keeps the temps under control. 

So, how is the Threadripper 2990X able to sustain an all-core 4 GHz boost on air? AMD's eXtended Frequency Range (XFR) 2 technology that was part of the Ryzen 2 launch has a key role to play here. XFR 2 can opportunistically increase clocks based on the available headroom and cooling. Therefore, if the stock Wraith Ripper is substituted for an AIO liquid cooling setup, expect the boost clocks to go much higher.

The Threadripper 2990X is already sampling and is expected to be available later this year for around US$1,800. While there will be new X399 Refresh motherboards at launch time, existing X399 motherboards will continue to be compatible with the new CPUs via a BIOS update.

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
