HW News: GDDR6, HBM3, Zen CCX Architecture, PCIe Gen4

2016-08-26
gddr5 X only just came out and Samsung's already trying to one-up micron with GG dr6 obviously is a numeric follower of gddr5 if that wasn't obvious and then of course SK Hynix is trying to start pushing HP m3 at least in the research and development side before HP MT is really on the mass-market so those are two of the main items for this news video but we've got a couple more coming up before getting to that this coverage is brought to you by iva power and their new element gaming PC with the full tempered glass side window and LED is it's basically an s3 40 that's been modified by iBUYPOWER if you're curious about what the base case is so gddr5 X is brand new that is from micron it's only found right now in the GTX 1080 and a Titan X Pascale cards and it operates at 10 gigabits per second on those devices but micron has previously demonstrated that the at least the earlier versions of the product were able to hit somewhere in the 13 ish 12 to 13 gigabit per second speed obviously that's not on the cards yet but memory tends to have a range like that like with gddr5 the kind of high-end that we're seeing today is about 8 gigabits per second from the best GPUs on the market with the best memory and then it'll scale down to something closer to 6 so there is a decent range there and that's true for the new GDD are 6 memory as well which Samsung details as having a range of about 14 years per second at the low end to about 16 at the high end so there's room for growth and it's still outperforming g5x today with the 14 gigabits per second of minimum gddr5 has been in production used since 2008 and in its present fully matured form it is operating at that eight gigabit per second number in the RX 480 and the GTX 10 series GPU is at least most of them Samsung's increased speed is only one of the advertised features right now there's also reduced voltage requirement for the speed so we're at one point three five volts for the 14 to 16 gigabit per second speed range coupled with lower voltages than even g5x by using LP 4x Samson indicates a power reduction upwards of 20% with post LP for memory Tecna and is looking toward 2018 for production of GDR six so that does actually give g5x some breathing room as of now as for HB m SK Hynix is already looking toward the world of HB m 3 HB m 2 in its current form is only really existent on the Tesla accelerated card accelerated card the P 100 using the GP 100 GPU that was the first Pascal chip shown so that's the only place that HP m2 really is known to exist in a form that's being produced right now HB m 2 obviously didn't hit the game inside of Pascal we're not quite sure when the next AMD series of cards will come out but we do know that they will feature HB m 2 so other than Vega what we're looking at for HB M 3 is a doubled throughput so it's theoretically on a 4096 bit interface with upwards of 2 terabyte per second throughput and that's 512 gigabytes per second per stack of HB m3 and we'll talk about this tech more in the semi distant future because it is a ways off there's also news this week from Tom's Hardware who spoke with some of the PC is IG folks to talk about power draw and the power allowance in the PCIe interface for version 4.0 this primarily detailed a minimum spec of 300 watt power transfer through the slot but could be upwards of 500 watts it's not finalized yet and without even talking out the bandwidth promises which by the way I moved to nearly 2 gigabytes per second per lane the increase of power budget will mean that the industry could begin a shift away from PCI Express power cables and the power would obviously still come from the power supply but it would be delivered through the pins in the PCIe slots and the cards rather than through an extra cable this same set up is what allowed cards like the sound 50 Ti and other low power cards to pull all of their power through the PCIe slot rather than requiring any PCIe power cables from the power supply at all so that's the future we're looking at and that would work on the high end cards on market today so it's pretty interesting one and the PCIe gen 4 spec should be ratified by end of year 2016 of course they're currently on version point seven point nine is to come and point-o should be before the end of the year one quick note that we don't yet know the rollout plans for consumer products so that's just ratifying the spec it doesn't mean it'll be available in platforms just yet and the also detailed more of its Xen architecture something we talked about last week when the company camped out near IDF Intel's conference and hosted its own mini conference of sorts to talk about Xen the summit ridge chips have primarily been on display thus far showing an 8 core 16 thread demo with and these implementation of SMT but we haven't heard much about other processors just yet and he is ditching modules from the bulldozer series in favor of new CPU complexes or CC X's each of these CC X units host for CPU cores and each CC X runs 512 kilobytes of l2 cache per core as seen in this block diagram with l3 sliced into four pieces of eight megabytes total for a low order address and relieve cache and these says that each core can communicate with all the cache on the CC X and promises the same latency for all accesses definitely big news and given this architecture it looks like the smallest chips in terms of core count will be four core units because each CC X does have four cores the only reason you would really see something less than this is if they're disabling cores either to fill a market or because a unit failed validation which has happened in the past but Andy's been moving away from things less than four cores for quite some time now so we would expect his end to stick to that trend at least for the market that we're most interested in on the gaming and sort of enthusiast user side of things so that's the main news items for this video check out the rest of the channel for reviews things like that we have an EVGA hybrid comparison coming up versus the MSI Seahawk and of course our hydrographic same card but that's coming up next week or very shortly anyway as always thanks for watching patreon link personal video I'll see you all next time you
