The AMD Ryzen 3000 processors are already a reality, and with them and their 7 nm technology comes the AMD X570 chipset.
And it’s good to know that we do have exciting news about this latest chipset in the new generation motherboards for the AMD platform. And also comes our obligation to make the comparison between AMD X370 vs X470 vs X570. Much more power in LANES, support for the PCIe 4.0.
AMD X570 vs X470 vs X370 Chipsets Comparison
X570 Chipset And Its Architecture
The current processors are characterized by having an architecture based on SoC (System on a Chip), and the AMD Ryzen in its three generations are an example of this. What does this term mean?
Well basically it is about installing on the same wafer or silicon of the process not only its cores, those that perform calculations and tasks, but also elements such as cache memory, and also the communication interface with RAM and with the PCI lines. Even in some of them we also have an IGP or Integrated Graphics Processor.
Basically, we are talking about the entire northbridge having been integrated into the processor, and this is an ultimate relief for board manufacturers and assemblers as the communication system is simplified quite a bit from the PCB point of view.
But a chipset is still required that is responsible for managing other elements such as peripheral connections, storage, and other elements. It is about delegating, so to speak, certain functions to the chipset called the southbridge.
The Importance Of The AMD X370, X470, X570 Chipset On A Board
Like any other processor, this chipset will have a specific calculation capacity and a certain number of lines or LANES through which the data that it is going to manage will circulate. There are different chipsets on the market for the Intel platform and the AMD platform.
AMD chipsets are divided into four families, the A, B, and X series which can be desktop or Workstation. Until now, and for desktop we had the basic A320 (low-end), B450 (mid-range), X370, and (high-end) X470 chipsets.
Completely discarding the low-end AMD A320 for being the most basic and without a place in this comparison, the B and X series chipsets are of interest, in fact, it is expected that the successor of the B450, called B550, will be released soon (September 2020). Remember that both have overclocking capacity, although with far fewer options and power than those of the X series.
Now the most exciting thing comes, and that is, the AMD X570 high-end chipset for the AMD Ryzen 3000 series has been finally launched. This is Yes, it brought much more news coverage than what the people saw between the jump from X370 to X470. And its fundamental characteristics is to incorporate support for the PCI-Express 4.0 bus, plus LANES and native support for USB 3.1 Gen2 ports at 10 Gbps.
AMD X570 Compatibility With Ryzen CPU
It is crucial to know that the new AMD CPUs will be compatible with older chipsets, just like an AMD Ryzen 2700X is compatible with the X370 and X470, now an AMD Ryzen 3950X will be compatible with X570, X470, X370, B450, and B350, as we say it.
And this is one of the remarkable things that AMD has since a user who wants to buy a new 7 nm processor will not need to change the board. They have to make sure that the manufacturer of the motherboard offers an update to the BIOS to make it compatible if they do not have it, it will not achieve that compatibility.
At this point we must have common sense, nobody should think of mounting a processor such as the 16-core 3950X in a mid-range and low-end chipset, and even in a previous-generation one. And one of the reasons is that we would lose the PCIe 4.0 support offered by the CPU and the considerable improvement in LANES.
In fact, AMD is directly disabling this option in its AGESA library so that this lane cannot be activated on boards other than X570.
That said, at least currently it will not be something that will take our sleep away since we now do not have GPUs that work on PCIe 4.0, it is more, this speed of 2000 MB/s is not even useful in each line of data both uphill and downhill. And we will also get an advantage from all this, and we will save the cost of having to buy CPU + Board.
We could also think the opposite:
Can I buy an X570 board and put my Ryzen 2000?
Of course, you can, as far as we know, AMD will keep its PGA AM4 socket at least until 2020 on X570 boards, but it is not a logical leap to jump off the shelf and keep the Zen1 or Zen2 SoC. Please note that 1st generation Ryzen CPUs with and without Radeon Vega graphics are in principle not compatible with X570.
AMD Ryzen 3000 is built in the form of a chiplet (different elements in different architectures). In fact, we have a RAM I / O memory interface made at 12 nm the same as previous Ryzen, while only the processing cores are manufactured at 7 nm. The chipset, on the other hand, is a 14 nm DIE, so in this way, AMD saves enough production costs to incorporate previous technology where 7 nm is not necessary.
AMD X570 vs X470 vs X370: Specifications And Comparison
To continue with the comparison, we will list all the specifications of each of the chipsets:
* Its functionality may be varied according to the manufacturer’s choice.
Up to 20 LANES To Manage
And without a doubt, the most important thing about this new chipset will be the LANES or lanes, and not only the chipset but also the CPU, and know-how they will be distributed. These Ryzen 3000s have a total of 24 PCI LANES. Sixteen lanes are used for the communication interface with the graphics card, and four are used for general use or NVMe SSD 1x PCIe x4 or 1x PCIe x2 NVMe and 2x SATA lanes, that is why one of the NVMe slots will always be directly associated with the hard drive.
The other 4 remaining lanes will be used to communicate with the chipset directly, and thus increase better bandwidth. These CPUs also support 4x USB 3.1 Gen2 which are often directly connected to them on the boards.
If we turn to see the power of the chipsets in terms of lanes, there is no doubt that the X470 chipset is a slight updated of the X370. The simple objective of X470 was to implement support with StoreMI similar to Intel Optane and to allow processors with higher frequencies in overclocking thanks to Boost Overdrive.
That said, we moved to the AMD X570, which does have significant improvements. We now have a total of 20 PCIe LANES at our disposal with increased processing capacity and support for the PCIe 4.0 bus. We know that manufacturers have limited access to these lanes to assign them for different purposes. In this case, 8 lanes will be mandatory for PCIe, and another 8 lanes may be used for other devices, like SATA or peripherals like USB.
Initially, support for 4 SATA connectors is foreseen, but manufacturers will be able to increase this number by up to 8 if they wish, as we will see in some high-end motherboards. The remaining 4 lanes will be used by the chipset to communicate with the CPU.
Increased USB 3.1 Capacity And Higher Consumption
The chipset offers great support of up to 8 USB 3.1 Gen2 at 10 Gbps, while the previous chipset was limited to supporting 2 of these ports and 6 USB 3.1 Gen1 at 5Gbps. It also supports 4 USB 2.0 ports. In an era in which connectivity is so important. The power of this chipset does make many differences compared to the previous ones, and if not, wait to see the specifications of the new boards.
Obviously, manufacturers have some freedom to choose how many of these lanes are destined for USB. Hence we have boards of different categories and costs, as always.
Likewise, the capacity to work with CPU and memory has been improved, with higher overclocking capacity, since in this case, RAM is admitted with higher frequency, depending on the situation, reaching up to 4400 MHz in the top models.
This also translates to higher power consumption; in fact, the X470 and X370 chipsets were consuming the same, 5.8W under load. Now the X570 has officially increased to 11W, although manufacturers and partners place this consumption at around 14 or 15W. This explains the incorporation of these large heatsinks with fans and heat pipes distributed by the chipset and VRM.
One problem that AMD of this chipset has yet to solve is precisely energy management since it never drops below its maximum frequency despite not being in use, which causes these considerable energy consumptions, and consequently, more heat.
And as we say, the VRMs of the motherboards have also undergone major changes, reaching up to 16 power supply phases in the ones with the highest performance, basically to improve the power delivery and signal quality by dividing the phases in greater quantities. This suggests that the overclocking of these new Ryzen will be more aggressive, obviously the considerable increase in cores and threads until 16/32.
So far our comparison of AMD X570 vs X470 vs X370 chipsets comes to an end. We see a lot of news between this new X570 and the previous two, which were basically simple updates of each other. All the information will be tested and reviewed thoroughly when we will analyze the new motherboards in-depth. We recommend reading the motherboard buying guide.
