AMD recently held a Threadripper 2 event in Maranello and while we weren’t considered good enough to be invited by the company – we do have some great news coming-in from the event that we aren’t bound by an NDA to not-share (good luck unravelling this sentence): AMD is introducing new Wraith coolers that will allow its flagship processor, the Threadripper 2990X/WX to hit 4.0 GHz on all cores on air. This is an absolutely incredible feat and is a subtle pun at the recent Intel debacle regarding the 28-core and the aquarium chiller.

AMD has been on a roll recently and it looks like their x86 come-back has yet to peak because the company is rolling out brand new wraith stock coolers that will allow the TR2 flagship to OC to 4.0 GHz across all cores out of the box! 4.0 GHz on such a mammoth processor, on air, is an absolutely herculean feat. To put this into perspective, Intel required a phase change cooler (which is a step above traditional AIOs) to OC their 28-core to 5.0 GHz. Granted 5.0 GHz requires exponentially more cooling power than 4.0 GHz, it is still impressive that AMD is doing this on stock coolers. As far as I know, no Intel extreme core count processor can hit anything close to 4.0 GHz on a stock cooler.
