ASMedia has reportedly landed orders to make AMD B550 and A520 chipsets for the Ryzen 3000 platform and will be supplying the same to motherboard OEMs by Q4 2019. These chipsets will continue to be based on PCIe 3.0 as PCIe 4.0 is currently exclusive to the AMD X570 platform. ASMedia is expected to tape-out PCIe Gen 4 designs by end of this year and will offer AMD chipsets with PCIe 4.0 support some time in 2020.

We know that the flagship AMD X570 chipset (and probably the X590 as well) was developed in-house and will be the only one to offer PCIe 4.0 interconnects for now. However, X570 boards can put big dents in the wallet so early mid-range and budget Ryzen 3000 buyers can opt for last gen B450 or X470 motherboards and perform a BIOS upgrade for drop-in compatibility. Or, you can wait out till ASMedia starts offering the mid-range B550 and entry-level A520 chipsets later this year.

According to a report by DigiTimes, ASMedia has received orders for producing AMD B550 and A520 chipsets. These chipsets will continue to be PCIe 3.0-based, and will be available to motherboard OEMs some time in Q4 2019. You won't be losing out much by staying on PCIe Gen 3.0 as most consumer GPUs, including the likes of the NVIDIA RTX 2080 Ti, do not yet saturate PCIe 3.0 speeds. Storage devices, however, stand to gain a lot with PCIe 4.0 with Phison has already announcing NVMe 1.3 controllers that can hit 5 GBps read speeds. 

DigiTimes also reports that ASMedia is expected to complete tape-outs for PCIe Gen 4 chipsets by end of 2019, which means motherboard OEMs will start incorporating them in their designs some time in 2020. Right now, PCIe 4.0 is exclusive to AMD and ASMedia is expected to win orders from AMD once the tape-outs are satisfactorily done. For those not in the know, a tape-out is the final phase of an ASIC design before it is sent to the fab. Motherboards based on these new chipsets will conform to AMD's PCB requirements for PCIe 4.0 and will also offer a PCIe Gen 4 x16 slot for discrete GPUs. They will also sport new wiring specifications for the VRMs, CPU, and memory that allow for improved overclocking.

ASMedia will also be rolling out USB 4.0 controllers in 2020 with major PC and motherboards makers expected to land orders for the same.

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
