The wait is over as AMD has officially announced its 2nd Gen Ryzen Threadripper HEDT CPUs, with the first pair releasing in one week, though pre-orders start today. At the top of the stack is the 2990WX, and just as the leak last week suggested, its 32-cores/64-threads have a base clock of 3.0 GHz and a boost of 4.2 GHz. The TDP for this processor is 250 W and it is launching on August 13 at the price of $1799. Also launching this month, but at the end (August 31), is the 2950X, which is the 16-core/32-thread part and it has 3.5 GHz base and 4.4 GHz boost clocks. The TDP of this part is 180 W and its launch price is $899, which is pretty nice since the 1950X it replaces launched at $999 last year.

Also announced, though not launching until October, were the 2970WX and 2920X, which are the 24 core and 12 core processors in the new lineup. The 2970WX shares the same clocks and TDP of the 2990WX, but will only cost you $1299. The 2920X will have a base clock of 3.5 GHz, a boost of 4.3 GHz, and a 180 W TDP when it launches at $649. Based on the stated L3 cache size, it is clear the two WX parts are using all four dies the chips hold, while the X parts are only using two active dies, as the WX CPUs have 64 MB and the X CPUs have 32 MB.

All of these new CPUs will work in existing X399 motherboards, though if you plan on dropping them into a current board, you may want to be careful about trying to overclock them, or at least the WX parts with their higher RDPs. To help keep things cool, CoolerMaster created the Wraith Ripper air cooler, which was shown off at Computex. The AMD press release says it is currently available, but at the time I am writing this, I did not see it on CoolerMaster's website.

Also revealed today is that last month at a special event, overclockers pushed a 2990WX to over 5.1 GHz on LN2, which allowed it to reach a record breaking score of 7618 in Cinebench R15. The previous single-socket record was held by Intel's i9-7980XE at 5828.

Ivan Cupa hit 5.955GHz on all 32-cores running LN2,.. that's impressive.   http://hwbot.org/sub...90wx_5955.4_mhz

It definitely is impressive. Seeing some of these overclocking results makes me wonder something though.

Which provides better cooling, LN2 or a water chiller like Intel used at Computex? LN2 is colder, no doubt, but a chiller allows the water to constantly flow, so while warmer it can still very efficiently pull the heat away. Plus there is move volume to store the heat (all of the water versus the pot of liquid nitrogen). The difference might only be relevant when trying to have a sustained overclock though, and not just a peak stable enough for a benchmark.

Either way we are talking about extreme overclocking but I do think it could be interesting to see what the TDPs are for the two cooling methods.
