AMD X470 Current Gen Motherboards Might Get PCIe 4.0 Upgrade With Ryzen 3000 Us

Highlights

PCIe 4.0 uses the same interface as PCIe 3.0 with faster signalling
Neither AMD nor Gigabyte have confirmed the feature addition officially
The X570 chipset is expected to be announced at Computex 2019 next week

AMD's Ryzen 3000 series Us and the accompanying 5xx series of motherboard chipsets have been rumoured to be the first to introduce for the PCIe 4.0 standard for interconnectivity, and now it seems to be confirmed that some existing 4xx series motherboards will have the feature enabled retroactively with a BIOS update. PCIe 4.0 doubles the bandwidth of the current PCIe 3.0 standard from 8GT/s (Gigatrasfers per second) to 16GT/s and the effective throughput from 16GBps to 32GBps. The PCIe bus connects a computer's U to its onboard components, and is most commonly used for graphics cards, SSDs, and communications devices. t3o3g

Gigabyte Aorus Gaming 7 Wi-Fi motherboard to the newly released F40 UEFI BIOS revision, and a new option for 'PCIe Gen4' has appeared in the PCIe Slot Configuration sub-menu. This motherboard uses last year's top-end X470 chipset and PCIe 4.0 has not been d. The change was first spotted by a Reddit who posted to the r/AMD subreddit.

With this update, s should be able to benefit from PCIe 4 speeds when a compatible multiple generations of Ryzen Us, new capabilities can come to older platforms with a simple drop-in upgrade.

The change will only affect PCIe devices connected directly to the U. Due to the faster signalling rate and electrical complexities of the PCIe 4.0 standard, not all PCIe or M.2 slots will be able to benefit from the speed increase even if motherboards are capable of handling it. For this reason, PCIe might not be enabled on all previous-gen motherboards. PCIe devices that are routed through the motherboard chipset or a downstream PCIe splitter will not be able to work at the higher speed.

All major motherboard manufacturers including Gigabyte, address the show's opening keynote, making a major announcement very likely. Leaks of X570-based motherboards have already confirmed native PCIe 4.0 . It is not known whether lower-end models from the current and generations will this standard.

The first consumer PCIe 4.0 devices likely to be announced by manufacturers are PCIe SSDs. AMD's Radeon VII could have announced retroactively.

The PCIe 3.0 standard was introduced with the Intel Z68 platform controller for 3rd Gen 'Ivy Bridge' Core Us in 2011. PCIe 4.0 has been anticipated for several years now. Each new version of PCIe has been backwards compatible, so all current and existing PCI 3.0 devices will continue to work, but they will only utilise half the bandwidth available per physical lane that they use. PCIe 4.0 will allow devices to work at their current speeds with half the number of physical lanes or at theoretically twice the speed using the same number of lanes.
