one of the things we wish AMD really did in their keynote was take more advantage of PCIe gen for being first on the platform that they were unveiling and unfortunately graphics and the 3d mark demo although interesting is not really the best use case for demonstrating PCIe gen for a lot of modern graphics cards simply don't need that much bandwidth but this is where it does get more interesting and that's because what we're looking at is a four by four so four lanes for four SSDs each 16 lanes total going through an add-in card four PCIe Gen 4 m dot two SSDs capable of driving upwards of 15 gigabytes per second read and write for sequential transactions before that this video is brought to you by the be quiet dark rock slim keeping a high-performance focused but reducing the footprints to accommodate full memory slot compatibility the dark rock slim comes with one of be quiet silent wins three 120 millimeter fans built for low noise operation the dark rocks limit vert eyes is cooling capability up to 180 watts EDP but mixes in a matte black out color design to combine performance and looks learn more at the link in the description below so for Gen 4 PCIe the real interest it's it's about two times the bandwidth of Gen 3 of the same Lane count and video card does state adjust they really don't generally especially in a gaming class need that bandwidth so eventually yes and the some extent if you're pushing all of your data through PCIe rather than through some kind of bridge like envy link or an equivalent then it gets more interesting and we've shown that data but with IO it does start to become more relevant so the intent of this card is to run up to 4 to terabyte SSDs and 40 terabyte SSDs with 4 slots you do end up consuming 16 lanes and ideally if you're doing something like this you put it in a workstation device but the rise and desktop CPUs can support as well it's just something that we'll have to have to remember this for when thread refer comes out so the way it's set up is you connect the SSDs in here as expected slots into the PCIe slot the slot that's connected to the CPU will be ideal if you want to boot off the drive you can't boot off of it if it's not in the primary can - CPU PCIe slot so for rising desktop you're only going to have 16 lanes going to one slot and then an additional four lanes going to an MDOT - SSDs somewhere on the board depends on the motherboard manufacturer where that is and so Verizon desktop then if you did want to use something like this if you were really I Oh intensive user you want something like 15 gigabytes per second we haven't validated that number but we've seen the the benchmark screenshots and obviously can do testing later perhaps but if you wanted something like that you do lose 16 lanes direct to the CPU for a video card on a desktop platform and that's why something like thread Ripper becomes more appealing because then you do have all of those extra PCIe lanes and they're on the cpu so that's really that's that's where the advantage comes in that we wish AMD had highlighted more in the presentations because graphics is just for Gen 4 vs. 3 it's really just not that interesting that's why you see a synthetic 3d mark test being used to demonstrate the differences because real games wouldn't or at least not presently so that's how its set up it does use redriver z' because the top two slots are getting far enough away from the actual PCIe socket that there is some signal integrity there's some signal integrity challenges along the way so reed drivers are used to propagate the signal further the PCB we don't know exactly the material or the type of PCB but it's supposed to be a slightly better PCB for signal integrity preservation I guess you could say so that the signal can reach all the way up to all four of the SSD slots that's much the card there's no price yet what we're curious about is if you want to want something like this it's a very specific use case so it is heatsink to which once you're driving this many SSDs perhaps becomes more of a concern and so there's a copper heatsink goes on top of it a single slot blower style cover and then a small fan which is currently being tested at 1800 rpm will probably have a fan stop mode for low load and might be retested for lower rpms because the copper heatsink is apparently doing well enough that they might not even need much active cooling but do you need that that's the question or if you don't need it is it something that you still are interested in or want and if so post a comment and say what you think you would pay for this because sounds like gigabyte is still in the deciding phase for some of this so you might have a chance to influence a bit of that depending on the market response and don't say $0 because that's not helpful to anybody so that's the main one I think we have some other information on that PCIe gen 4 of course the pricing TBD might be bundled with AOS branded SSDs up to 2 terabytes thermal pads or 1.8 watts per meter Kelvin for those pretty standard the there's back plate no functional purpose just looks better and no RGB LEDs because it's workstation focused so you could maybe just buy it to protest LEDs if you wanted to do that thread report focus for bootable otherwise you could use it in something else just you're gonna you're going to have Lane allocation issues so you'll need to research the chipset and the CPU you're buying and make sure it'll work out for you and apparently the way this works further is that each chip lit on the the Rison platform can see two drives and so that's what allows all four to be run and raid and for the numbers we gave you earlier the 15 gigabyte numbers that was in a striped not mirrored raid or an array then for the other device this is pretty heavy it's 77 gram heatsink and it's just copper so copper heat sink goes on to the SSD won't be sold separately from the SSD you'll have to buy the SSD from gigabyte to get the heatsink as well and the pricing is $270 for one terabyte files on e 16 controller SSD and I think this is going to be called an ARS nvme M to Gen 4 SSD res the other devices in a or SAIC Gen 4 SSD for the names and maybe have 8 TB there at the end so it's just it's a fat heatsink and I suppose that's really all there is to this one but that's it for the gigabyte expansion stuff at the show we'll have a separate video on the motherboards probably already live 4 X 570 check back for that subscribe for more as always thank you for watching go to store like Aaron's X's on that top side directly or patreon.com slash gamers axis I'll see you all next time
