Repeat. 1 Terabyte of system RAM in a consumer PC.  Still, the big news came on July 13 when AMD finally dropped the other shoe and announced jaw-droppingly good prices for its 16-core and 12-core Threadripper CPUs. Threadripper’s clock speeds and August release window were also revealedAMD’s  Ryzen Threadripper chips could very well be the most powerful consumer  CPU ever introduced when it releases in August. With up to 16 cores and  32 threads, Threadripper gives the high-performance Intel products  currently dominating high-end desktops something to worry about.The  mega-core CPU battle is now quickly turning into an arms race. Check  back here for all the latest information about Threadripper as more  details become available.<img src="http://images.idgesg.net/images/article/2017/05/dsc06715-100724348-large.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />The specs we know <ul> <li data-xf-list-type="ul">The Ryzen Threadripper 1950X features 16 cores with simultaneous  multi-threading (SMT) for 32 threads of compute power.

The 16-core Ryzen  Threadripper 1950X will cost $1,000, while the 12-core Ryzen  Threadripper 1920X will cost $800.How disruptive is that? Well,  with Intel’s 16-core Core i9-7960X pegged at $1,700 and it’s 12-core  Core i9-7920X priced at $1,200, it’s easy to see Threadripper will  likely be as disruptive to Core i9 as Ryzen 5 and Ryzen 7 were to Intel’s Core i5 and Core i7.What do we know about Threadripper’s performance?We won’t know the full effect of Ryzen Threadripper’s 16 cores and 32 threads until we test it. Meanwhile, our reviews of Ryzen 7 and Ryzen 5 can give you insights into the strengths and weaknesses of the Ryzen family.AMD,  however, has given us a taste of just fast the chip will be in  multi-threaded tasks. In a controlled demo from an AMD lab, AMD CEO Lisa  Su showed off the 12-core Threadripper 1920X socking the 10-core Core  i9-7900X with a Cinebench R15 score of 2,431 to 2,167. The real beatdown  came from the 16-core Threadripper 1950X though, with a score of 3,062.<img src="http://images.idgesg.net/images/article/2017/07/1920x-vs-7900x-100729000-large.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> AMD  AMD’s results pitting the $800, 12-core Threadripper 1920X against Intel’s $1,000, 10-core Core i9-7900X in Cinebench R15. Keep in mind that we don’t know details about  the configurations of the test PCs. The machines were also in the  control of AMD, which always sets off conspiracy theories, but AMD’s  previous Ryzen performance demonstrations matched the final parts, so  this is likely a true predictor of Threadripper’s performance in 3D  rendering in Cinebench.We’ll go out on a limb by saying that  AMD’s disclosure of the base clock speeds promise decent performance for  most tasks. The 16-core Threadripper 1950X features a base clock of  3.4GHz, while the 12-core is slightly higher at 3.5GHz. Both will hit  higher boost clocks of course, but the guaranteed minimum base clock is  quite promising for performance considering how many CPU cores the chips  have.Bigger  chips tend to be difficult to scale to high clock speeds due to the  thermal and power limits. For example, Intel’s 16-core Xeon E5-4660 v4  has a base clock of 2.2GHz with a boost of 3GHz, while the new 3.3GHz  Core i9-7900X has earned a reputation as being a hot head, especially if  you overclock it.This horse race really won’t be answered until we have all the players on the field of battle so stay tuned for more.It will support up to 1TB of RAMNo,  we're not kidding. Threadripper shows its server roots and will be able  to support up to 1TB of RAM if you populate all 8-DIMM slots with 128GB  LR-DIMMs or Load Reduced DIMMs. Unlike today's Registered DIMMs that  use a chip to redrive some of the signals to the memory directly from  the CPU an LR-DIMM uses a memory buffer to re-drive all of the data and  instruction sets.None of this comes cheap though. A single 32GB  LR-DIMM  DDR4/2133 module costs $1,100, so you can imagine how much a  128GB LR-DIMM will cost when available.And yup, if you guessed,  the typical person doesn't need 1TB of RAM, but in the "look what I  could if I wanted to category," it's a major bragging point.This factoid was actually noticed by Anandtech in a video Alienware published last month.What about the 14 and 10-core versions?With  16-core and 12-core Threadripper chips now out in the open, people  expecting 14- and 10-core Threadripper CPUs (and full parity with  Intel’s Core i9 selection) might be disappointed. AMD hasn’t said boo  about any further Threadrippers yet despite earlier leaks indicating a  fuller lineup, and AMD executives have told PCWorld it’s not even clear  they feel they have to match Intel’s offerings.<img src="http://images.idgesg.net/images/article/2017/05/ryzen_threadripper_socket_with_skylake_x-100724182-large.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />   Threadripper isn’t huge, it’s yuge. In fact, that’s the plastic load plate protector of a Core i9 hovering over a Threadripper TR4 socket What about the X399 chipset and other specs?At Computex, AMD revealed that all Threadripper CPUs will feature 64 PCI-E lanes  and quad-channel RAM support on the X399 chipset, but other hard  details of the chipset aren’t known. What do know is that the new chips  TR4 socket is yuge.Threadripper is also AMD’s first  consumer chip to move away from the older pin grid array (PGA) design to  the same land grid array (LGA) as Intel’s chips. In other words,  Threadripper’s pins are in the motherboard socket, not on the chip  itself. That means you can’t bend pins on your AMD chip anymore. Hurray!  The bad news? You can bend the pins on the motherboard and trash that  instead.The other detail AMD slipped out is what the maximum  thermal budget is for the chip and it's a doozy. The company said both  chips have a TDP of 180 watts vs the Core i9 7900X's 140 watt TDP.Before  you scream that it'll be too hot to cool, one thing you remember is  that Intel and AMD haven't always used the same definition of what a  Thermal Design Point is. Intel's Core i9 is also getting a pretty bad  reputation for being too hot to handle as it is.Even more insane is this fact: The 16-core Ryzen Threadripper 1950X's 180 watt TDP is still 40 watts less than the AMD 8-core FX 9590 CPU which had a 220 watt TDP.What about Core i9?<img src="http://images.idgesg.net/images/article/2017/05/intel-x9-speeds-and-feeds-updated-100724042-large.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />   The Intel X-series and Core i9 lineup. AMD isn’t the only company working on monster  CPU for consumers. With Intel’s Skylake X or Core i9 finally breaking  from cover, the battle is joined. Well, kinda. As you can see in PCWorld’s Core i9 review,  Intel’s new HEDT chips are indeed fast—but there are caveats to that  performance. Far worse for Intel though are the combatants it can put  against Threadripper immediately. Threadripper’s coming in early  August. The best Intel can muster is a 12-core Core i9 chip also slated  for an August launch. The 14, 16 and 18-core chips? They won’t enter the  fray until at least October, which means Threadripper is likely to be  unopposed for a couple of months.Our CPU hounds debated and  dished on Core i9 vs. Threadripper during our “Full Nerd” show. They  also took bets on the pricing, so see if someone has to eat paper in  this video. Core i9 uses a new X299 chipset,  and the top-of-the-line Core i9-7900X features 44 PCIe lanes and  quad-channel memory support. You need to spend at least $1,000 on a  10-core Core i9 chip to get more than 28 PCI-E lanes, though. Will you really benefit from that many cores?<img src="http://images.techhive.com/images/article/2017/05/18_cores-100723069-large.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> IDG  Even Handbrake can’t use all the resources of an 18-core, 36-thread  CPU, so buy a mega-core CPU only if you can really use it properly. With Intel and AMD waging a fierce a core war  this summer, you’d assume that more cores means better performance. The  truth is more nuanced.How many cores you need really depends on  what you do. If you primarily play games, a mega-core PC isn’t likely to  yield the performance you’d expect. If, however, you edit video, render  3D, and run other intensive workstation-like tasks, more cores  generally means less waiting. Having an embarrassing number of cores can  also aid in heavy-duty multitasking. You know, like simultaneously  rendering 3D, video, audio, and playing games. <img src="http://images.idgesg.net/images/article/2017/05/ryzen_threadripper_and_mobile-100724349-large.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> IDG/Gordon Mah Ung  AMD’s new 16-core Ryzen Threadripper (left) dwarfs the 4-core Ryzen mobile chip (right). </blockquote>
