everyone were interrupting our moves to bring you some threader for two news so in this one everyone else will be posting specs and prices we've got those too but we also have some extra information not too much about the architecture side and while more of the topology of how threader for two is arranged under the IHS we'll be talking about that a bit today showing a topological diagram of threader for two basically a block diagram talk about the specs and prices and then we'll get back to moving into our new office before that this video is brought to you by NZXT is new h 500 case which we recently found to have an impressively effective cooling setup that is entirely negative pressure when stock the h 500 is the successor of the s 340 and s 340 a lead offering that high build quality that's all steel and glass and kale management features that are also top class for the $70 compact mid tower case age 500 is a part of NZXT Zanu H series lineup which also features options from mini ITX micro ATX and full ATX builds learn more at the link of the description below so the quick basics here just like with rise in 2000 series we're not technically working with AMD on this launch they did not provide any documentation although at the last hour they did offer we ended up getting all of our information elsewhere so not not technically working with them on this one but out of respect to everyone else we'll keep the information we do have mostly limited to what's lifting out embargo although keep in mind I don't 100% know what's under embargo and what isn't because I wasn't part of the meeting so anyway we've got some news for you and might have some testing later on just depends on how things work out with the move so first thing here the configuration Andy's got a few processors we'll go over those in a minute the 2990 WX probably the most interesting it's the flagship halo product it's pretty high it's their highest end processor 32 cores 64 threads we'll talk about that more momentarily and this one uses the cores enabled in all dies so that's the most interesting part of this is with I'm looking for my original thread Ripper a diagram but our original thread record algorithm showed how just two of the dies out of four actually have active cores and that was true for the entire 1900 series so with this one the 2990 you X is moving to four active dyes and it has cores across all four of them will talk about the topology - that's it's kind of interesting because two of the dyes are basically i/o controllers and the other two are connected via infinity fabric basically just an interconnect so that's the 2990 WX and this one more or less confirmed there Bauer's findings where he got into a bit of a battle with AMD earlier this year about whether a thread Ripper had just deactivated dyes that could potentially be usable via epoch so more or less confirms those findings 2958 W act or 2950 X rather than the 2920 X are these successors to the existing 1920 to 1950 X in terms of the core and thread count and these will be using dyes 0 and 1 leaving the other two unutilized just like the original threader for one launch no changes there I think we're pretty sure it's even going to be the same dyes which would be nice because that means that anyone who had special flow plates for liquid cooling won't have to change the configuration ZK included and improvements over threader for one include more of the same stuff we saw for the rise in 2000 he pees on these n+ architecture not to be confused with Zen - and rise in 2000 not to be confused with Zen do as well so more of the same stuff this includes cache latency drops they've dropped cache latency about 15% on l3 cache 9% on l2 cache and 8% on l1 cache and DRAM latency was also reduced by about 2% with an increase in official JEDEC supported speeds - 29 33 megahertz from 26 66 megahertz previously again that's official JEDEC support not to be confused with maximum memory support so you can clock higher but that's the official Jetix support which means that overall memory compatibility would be improved over 30 for one just like with rise in 2000 series where you had motherboards like x4 70 primarily improving their bios and memory timings and auto timings you'll see more of that and thread over 2 as well so here's an image we made that shows AMD is threaded for two SOC topology it's not much different than the 1950 X at its core this is the 29 50 X using two memory channels to connect dyes to memory 32 PCIe each and IO operating about 50 gigabits per second with a 1600 megahertz memory clock assumes cores 0 through 15 are on dyes 0 in the diagram with cores 16 to 31 on dye one in theory AMD is enabling the same two dyes in every single processor individually so hotspots shouldn't change in TR 2 between TR 2 CPUs this is good news again for cooling manufacturers as for the memory channels like with Red River one these can be pulled into a single um a or uma domain rather than two at Numa domains this is user configurable and depends on whether you want latency for gaming or pools for production local mode or Numa is useful for reducing memory latency like in games while uma or um a is ideal for even spread of memory hits across the channels basically distributing the transactions this image shows the 2990 W X block diagram it's not too different but gets a bit more complex when given the extra two dyes dyes 0 and to hold the direct buses to PCIe and DDR with dyes at 3 & 1 simply sitting between infinity fabric lines to the main i/o controller dyes thread referred to will be on 12 nanometer LP or leading performance this is largely what enables clock speed increases that were seen in rise in 2000 and has been carried over to thread over 2 and also has a note the tr4 socket will remain compatible CB expects and pricing and stuff that you'll probably have seen by now these are there are a few of them this time more than the last time this so 29:20 is a 12 core 24 thread part that replaces the 1920 x directly in core account 3.5 to 4 point 3 gigahertz with XFR to 3.5 bays 650 bucks for that one so this most immediately replaces the 9 to 20 X which for reference is presently $520 about 130 bucks more has the same core and thread count but it has some frequency changes latency changes to cache and better JEDEC memory support this runs the 1920 exercises runs up to 4.2 gigahertz and the 29:20 x will ship in October 29 50 X this is 1600 or 32 threads we should have a table somewhere on the screen eventually and this one runs 3.5 gigahertz base to 4.40 Hertz EXIF are 900 bucks and replaces the 1950 acts of the same core accounts $100 cheaper than the Knights and 50x at launch price but currently the 1950 acts is around 780 dollars today so it's significantly cheaper it's just you lose a lot of the gains and some of those gains include the frequency or the 1950 X capped at 4.0 gigahertz and you could boost it a bit more manually via XO far or via manual overclocking but that's about where it's at this one ships sooner it ships in August the 2970 WX 24 Core 48 thread processor 3.0 gigahertz base to 4.2 gigahertz boost $1300 and this is a new CPU line for AMD ships in October and finally 2990 WX is the halo products this one is 32 cores 64 threads 3.0 gigahertz based 4.8 gigahertz boost $1,800 ships August 8 I believe and 64 PCIe lanes on this one still quad channel runs 4 by 213 millimeter squared dies 250 watt TDP on this one so speaking of TDP and these formula for calculating TDP is a bit different than Intel and NVIDIA doesn't mean any one of them is necessarily wrong it's just that they all do it a different way so this one for AMD they calculate it for the 2950 X which is listed as 180 watts EDP they calculate it as follows TDP and watts equals T case degrees Celsius minus T ambient degrees Celsius divided by the heat sink fan thermal resistance so just to be clear T case is the case temperature as reported in some software monitoring tools as opposed to T Junction which is the one that we normally care about more T case is going to be your basically your IHS temperature the t ambient measurements is the ambient temperature and then the heat sink fan thermal resistance is shown as degrees celsius per watt so AMD calculates its 180 watt TDP by taking a 56-degree assume the optimal processor to mid temperature for the IHS and subtracting a 32 degree pretty high ambient temperature if we're honest and then calculates a versus a 0.133 thermal resistance which they have deemed to be more or less optimal so that's how they calculated we'll talk more about this later as for T CTL same as last time it's a 27 degree offset just like starter for 1 and then performance metrics here so despite AMD making a huge fuss about media testing games at 1080p last year for some reason I guess they did they forgotten what it was like to work with media at that point can't blame them too much AMD is now testing hence head ATP themselves so and these performance lab and notes do note that their gaming test suite was done at 1080p go figure that's how you show a difference and regardless AMD showed on average about a 6% decline versus Intel when comparing for similarly priced parts this is actually pretty damn good for Andy we obviously we have to independently validate it if we ever do other people well if we don't but let's just take them at their word for right now it was over a pretty big suite of games they looked ok we looked at their game suite and honestly it doesn't seem like they're trying to pull one over on anyone which is cool because it's not often that a company will show any downsides even if they're minor and even if they're outside of the use case so processor is clearly meant to be used for production and they went forward with a game and test anyway showed a 6% decline and we're ok we actually I'm pretty happy to see that they they did that that takes takes some courage to do that 6 percent though not bad at all if we take them at their word because you're considering going up against Intel and gaming they've had a lead and he's gaining there and then Andy has theoretically should have a lead with right over 2 and a lot of production tasks like handbrake blender Cinebench if that matters to you cinema 4d stuff that actually uses the thread count so they've got potentially big advantages in production departments were the targeting with not a huge loss in gaming and then of course that is taking all the documentation at its word but we did look it over and it seems actually pretty fair overall we looked through all the endnotes all the testing Suites and all that stuff and it looked not bad so wait for independent analysis but honestly pretty good-looking overall so far so other performance figures AMD is using an H 100 i CLC closed loop cooler it's actually not one of the but it's it's pretty good but to put out if they were at max fan speed or not is kind of the question we have to assume they likely are because that's just I mean that's how we would do the testing that make sense and and it is a high tea TV part so either way though h100 ICL sees a 240 millimeter closed loop liquid cooler not one of the best on the market the fact that they're able to use that on a twenty nine fifty x and a twenty nine ninety WX before stock testing shows that despite higher TDP thermals might actually be pretty under control so it is going to be a hot process all of these will be hot processors relatively speaking to the rest of the market but an h1 her IC LC is promising it's just a question whether it's Mac's fan speed or not because then you're talking like 50 plus decibels which most people don't want to tolerate on a part so fortunately you can solve that with mostly a 280 C LC and lower fan speeds so anyway it looks good overall it's just wait around for independent analysis hold pre-order stuff like that thermals should be more or less under controlled if you're controlling for voltages and then motherboard support to be determined the x3 99 creation is probably the best one we've seen so far and the ACS looks like they're sticking with their existing boards which they're going to be shipping optional vrm cooling brackets for those because the VRMs will get really hot if you actually overclocked thread her Purdue as opposed to running it stock where it should be mostly okay so that's it for the threader Pitou news not clear on what's embargoed and what's not Andy did reach out last minute they didn't send any documentation over we got it separately and we will be looking at potentially sourcing parts as well whether we buy them or have them shipped via third parties not sure yet still move into the office but so no promises on if we're covering this particular product on a bench but will probably be testing some of the threader for two parts it's just we're not sure which ones and some of them come out in October remind you so maybe look more for those anyway that's it for this one subscribe for more as always the move is still going on with posting more moving videos the David Cantor interviewer we talked about ten nanometers coming up probably pushing that out to Wednesday most likely and then go to store documents next to snot net to pick up one of our mod mats we still have a few in stock they're shipping really fast so thank you for the support if you buy it today like as and when this video goes live you'll definitely get one ship and then our posters video card posters for video card Anatomy are still in the store as well patreon.com slash gamers next directly therefore bonus behind-the-scenes videos I'll see you all next time
