AMD Readies Z490 Chipset with More (and Faster) PCIe Lanes

Posted on
AMD is reportedly readying a new high-end motherboard chipset positioned increased than even its upcoming X470 chipset, which makes its market debut on April 19. The new Z490 chipset, because it’s referred to as, is rising to be considerably completely different from X470, and will lastly overcome its largest limitation – downstream PCIe connectivity. Whereas the X470, like its predecessor, places out simply 8 downstream PCIe lanes, that are PCI-Specific gen 2.0 at that, the new Z490 will put out a complete of 12 PCI-Specific gen 3.0 downstream lanes, which is able to power further bandwidth-hungry units, comparable to further M.2 slots, external USB 3.1 controllers, 10 GbE controllers, and many others. The Z490 was first leaked by means of a GIGABYTE Aorus internal presentation.

In its present implementation, socket AM4 motherboards have a complete of 24 PCI-Specific gen 3.0 lanes from the AM4 SoC, apart from 6-8 gen 2.0 lanes from the chipset. From this SoC price range, 16 lanes are allotted for PEG (PCI-Specific Graphics), 4 lanes as chipset-bus (connecting the SoC with the chipset), and the remaining 4 lanes powering one 32 Gbps M.2 slot. Extra M.2 slots are both gen 2.0, from the chipset’s downstream lane price range, or break up from the PEG price range. The Z490 overcomes this with a downstream PCIe root advanced that is not simply 50% broader, but additionally twice as quick, with PCI-Specific gen 3.0. The remainder of its feature-set seems to be equivalent to the X470. There is no timeline on after we can anticipate Z490 to launch.
