AMD Ryzen 3 1200 and 1300X review - The AMD Chipsets

The Chipset(s)

A new processor will need a new chipset. AMD sold its chipset division I think two years ago already, a new processor series will need a new chipset as the motherboard needs an infrastructure as well. While most of the chipset functionality is harbored inside the processor, a new generation and architecture processor will always require a new motherboard chipset.
  

 
AMD announced chipsets for Ryzen based on AM4: X370, B350, A320 and the mini-ITX X300, and A300/B300 with the X370 and B350 already available. Only the X370 chipset is going to support SLI. That means the B350 would not support SLI (but does support Crossfire). This information has been confirmed. The B350 series is a more budget aimed one so that choice makes a lot of sense. Please notice that there are 20 PCIe 3.0 lanes pulled from the Ryzen processor. Ryzen all by itself has 24 PCI-Express lanes, 4 are being used to interface with the chipset (which adds Gen 2.0 lanes as shown in the tables). So depending on the chipset used it adds gen 2.0 PCIe lanes through the chipset. The X370 will add 8 lanes, B350 6 lanes and onwards. Have a peek at the chart for more details. Let's check out the I/O interfaces of the chipsets and processors:

  
Each chipset will add USB ports, but the Ryzen processor also offers four native USB 3.0 ports. There is support for RAID 0/1/10 configurations as well as overclocking support on the X370, B350 and X300 chipset. Obviously the motherboard partners can add 3rd party chips to increase USB 3.0 and so on.
  

 
For you guys two series will jump out the most, high-end enthusiast class end-users will go for the series X370 chipset whereas the B350 series hints towards the budget or business side of things. Mind you, there will be five chipsets for Socket AM4, namely the X370, B350, A320 and, for smaller form factors, the X300 and A300.

DDR4 DIMM Memory Support

AMD obviously brings DDR4 support to Ryzen, this remains to be dual-channel; we certainly would have liked to have seen quad-channel support to be brutally honest. The motherboards will be paired with 4 DIMM slots, again in dual-channel setup. AMD will support the standard Jedec SPD timings and frequencies at 2133/2400 and 2667 MHz, but we have already tested motherboards which support 3200 MHz in OC mode. So yeah, that will be solely dependent on the motherboard partners. While that is not in the same ballpark as what Intel is doing, a nice 2933 MHz kit with CL16 latency would be very sufficient for all your bandwidth needs. Ryzen processors really like fast memory, hence we recommend 2933 or 3200 MHz single rank dual-channel kits. Please check this article for some more advise on your purchasing choices.

AMD X370 Chipset (High-End)

Other than that, PCI-Express Gen 3.0 is now confirmed as well as support for the NVMe protocol, USB 3.1 Gen 2 (10 Gbps) and M.2 and SATA Express support. Interestingly the Ryzen processor has IO paths and a controller built in for USB 3.1 (Gen 2) as well as 4 PCI lanes dedicated to your NVMe needs. The chipsets can be used for adding more as well of course. So the most high-end chipset will be the X370 with that 'X' for 'Extreme'. This chipset will support Multi-GPU rendering (Crossfire and SLI) with two x16 PCI Express slots (Gen 3.0). The Ryzen processor has an I/O of 24 PCIe 3.0 lanes. Four of them are used as an interconnect to the chipset and then the chipset adds another 8 PCIe 2.0 lanes. So if you run Crossfire or SLI, you will be running at Gen 3 x8 modes. The chipset will support overclocking. Basically this is the chipset series you and yours truly will be using much like Z170, Z270 and X99 for Intel. 

AMD B350 Chipset (Mainstream)

If it has a 'B' in the naming schema, you should think mainstream and that 'B' is for 'Business'. A more generalized chipset that offers full performance, yet less tweaking options and often less PCI-Express lanes available, the mainstream series. For B350, specs show 8x Gen 3 PCI-Express lanes for graphics, it'll add/hook another 6 Gen 2 lanes through the chipset and will offer a wide variety of USB connectivity. This motherboard series will offer dual channel DDR4 memory.

AMD obviously already showcased high-performance AM4 motherboards from several manufacturers, including ASRock, Asus, Biostar, Gigabyte and MSI as well as innovative third-party CPU cooler designs, demonstrating a ready and robust ecosystem for Ryzen CPUs. For us gurus the most interesting will be the X370, X300 and B350 series. X370 chipset-based motherboards are designed for those who need the most performance, features, and I/O connectivity from their PCs including support for overclocking, and dual graphics. For users looking for performance in a more compact size, the X370 chipset also features an AMD Ryzen-ready AM4 socket while utilizing the mini-ITX size ideal for small form factor PCs. Both chipsets take full advantage of innovative technology features including:

• Dual-channel DDR4 memory
• NVMe
• M.2 SATA devices
• USB 3.1 Gen 1 and Gen 2
• PCIe 3.0 capability

AMD Ryzen Master Utility

Tweaking and overclocking can be managed in two ways. Standard traditional tweaking can be managed in the BIOS of course. I assume 99% of you guys will do just that. However, AMD is introducing their Ryzen Master Utility as well. You might recognize the design as the tool is styled in the very same way as Radeon Crimson drivers, it works the same and feels the same. The tool has been designed to tweak and overclock the basics like your clock frequency, voltages, memory and core parking. Once you OC above 3.7 GHz, the protection will switch off and stuff like XFR is automatically disabled for you to gain maximum performance. Ehm, yeah - we'd still advise a BIOS OC though.
