and these X 570 chips have marked the arrival of some technology that was first deployed on epoch although that was done through the CPU as there isn't a traditional chipset with the shift to PCIe 4x why so many motherboards have grown more complex than x3 17 x4 70 furthered by difficulties cooling the higher power consumption ax 570 chipset all these changes mean that it's time to compare the differences between X 374 70 and 570 motherboard chipsets hopefully helping newcomers to rise and understand the differences along the way before that this video is brought to you by Thermal Grizzlies conduct a not liquid metal conductor not as what we've used in all of our liquid metal and delayed thermal tests capable of dropping CPU thermal significantly and replacing the stock thermal interface over CPU thermals don't just allow better overclocks but also lower noise levels because the transfer efficiency is increased the mix of gallium and indium makes for a thermal conductivity of 73 watts per meter Kelvin outclassing traditional pastes significantly learn more at the link in the description below this video is only focusing on the differences in the chipset so that's gonna be IO it's entirely i/o a little bit of power consumption but what we're not talking about is compatibility between the CPUs and the chipsets or the motherboards technically you they are all kind of cross compatible but there's some caveats there like losing PCIe gen 4 on the older boards and they will be disabling PCIe 10 for as a toggle in the new age ISA updates coming up motherboard manufacturers could theoretically overcome that if they were willing to dig through the binary and figure out which toggle to flip to true instead of false but that stuff we're not really gonna get into here what we're focusing on is i/o and power will start with power so chips had average power before we get into IO is measured at about 11 watts on the XY 70 chipset this is information direct from and the at their editors tech day board partners have told us that the peak chipset power consumption they've seen is around 14 watts and some board partners have also told us that they've seen up to 15 watts which could be an early alpha version of the chipset but officially from AMD we've been told 11 watts average and 14 watts peak although that may change going forward depending on how and the updates its its firmware micro code and things like that so at present the chipset doesn't down clock during loads what it does is it sits there burning at a higher power consumption than the older chipsets which we're about 5.8 watts and that means you have an active chipset fan on almost every motherboard some of them can get away without it with enough heatsink mass and service area but most of them will have a fan because it does burn closer to the 11 watt number constantly X 570 has been Andy's biggest challenge with rise in 3000 launch it has caused the delay of the launch at least once as far as we're aware and the difficulty seemed to stem from the added complexity and power consumption requirements of PCIe gen 4 but now that those have been for the most part conquered other than the higher power consumption issues the chipset is shaping up to have a significant amount more IO capabilities than the old one so we'll talk about that next let's get into the specs the Rison 3000 CPUs have 24 total PCIe lanes four of those our general purpose or nvme SSD lanes so you get four by Gen 4 straight to the CPU for SSDs with 16 used for PCIe graphics lanes remaining four lanes go straight to the chipset and allow more bandwidth for chipset to CPU transactions the CPU further supports four USB 3.0 two connections and a pic one choice of either one by for nvme or one by two nvme with two SATA ports extra the chipset has 20 PCIe lanes 16 of which are assignable for i/o motherboard manufacturers have some limited level of freedom to assign lanes between devices like PCIe slots SATA USB high-speed devices or high-speed networking depending on the goals of the motherboard eight of X 570s lanes are always PCIe the other eight can be MUX down for things like SATA or those other devices and as a reminder your graphics lanes typically come straight from the CPU which has 16 allocated for PCIe 4 in the actual PCIe slots the x5 70 chipset also supports 4 USB 2.0 ports 8 USB 3.2 gen 2 ports and two sets of a pic 1 choice of either a single use of 4 PCIe gen four lanes dual device use on a by 2 configuration of PCIe John for each or 4 SATA 6 gigabits per second lanes this is going to be where the motherboard manufacturers make some decisions on where to allocate lanes to different slots or ports finally the chipset natively supports 4 SATA 3 ports which can be increased by burning one of the pick 1 choices on an additional for or by using an external controller although that would reach levels where you probably don't need that many here's a chart comparing X 570 versus the previous generation the biggest change is obviously Gen 4 all the PCIe lanes on X 570 are Gen 4 whereas that didn't exist on desktop platforms previously the X 470 and X 370 chipsets were actually the same as each other but the only real difference being major up fits to motherboard BIOS by the manufacturers X 470 motherboards generally solved a lot of X 3 seventies and memory issues that were early in the life of Rison and that was a more biocide or trace routing than anything X 470 was more of the demarcation of that BIOS upfit not an actual chipset change the asterisks in this table indicate places where numbers could change based upon the pic one option used by the manufacturers lanes can be assigned elsewhere as needed within the limitations of the x5 70 chipset the other major change is the move to support 10 gigabit per second USB 3.0 gen 2 ports up to 8 natively as always motherboard makers can expand support for some of these items by adding third-party controllers on the board but this is rarely done as cost and complexity increase and also it starts to become unnecessary power consumption is something we discussed earlier in this video but it's also the last thing to mention for point of reference if you're wondering well what is 11 to 14 Watts really mean the x4 70 Knox 370 chipsets we're about 5.8 watts so it's a pretty significant increase it's enough of one where most of the board's will need a small chips at fan or just a massive heatsink on them Verizon 3000 the iodine rise in 3000 packages is 12 nanometers the i/o diam X 570 chipset is 14 nanometers and the CPU dies are seven nanometers this split allows and the cost savings on dies that don't show enough gains to justify the 7 nanometre fab cost because we're there while there can be gains it's not necessarily actually worth it once the testing comes out and shows the differences so that's a clever way for Andy to save on cost by mixing and matching the fabrication process and that'll if the chipset differences it's really pretty easy some of our io changes but mostly PCIe gen3 general purpose lanes become PCIe John for general purpose lanes and those can be assigned to all sorts of things on the board as shown in some of the diagrams and the the tables we showed earlier and overall it's a difference in the capabilities of a chipset from an i/o standpoint but keep in mind that your CPU has to support PCIe gen 4 if you do want to take advantage of it your motherboard has to support it of course and in terms of putting a new CPU in an older socket don't expect it to work with the upcoming 2 GC updates from AMD that sort of the underlying code that gets used in all the all the firmware so that could change but the motherboard vendors would have to dig through binary it's not presented as source code and that means that it might be a while before someone reverse engineers it but we'll see the biggest thing though is just make sure that PCIe gen 4 supports arise in three thousands use for that the AP use although being de marketed as three thousand are not using these n2 architecture so keep that in mind as well if you're buying an APU but that'll cover us for this one we will talk about the lower end chipsets as they come out the B series is not launching for July 7th launch of the news n parts it'll be coming later we're not sure exactly when but it will be significantly later from what the motherboard vendors have told this but that's venting it's a rumor land so we'll kind of leave that there because we don't actually firmly know thank you
