Rumored AMD X590 chipset touted to offer even more PCIe 4.0 lanes for premium Ryzen 3000 CPUs
The AMD X570 platform has earned the distinction of being the first mainstream platform to offer PCIe Gen4 support for the new Ryzen 3rd generation CPUs. With 16 PCIe Gen4 lanes for I/O, four dedicated lanes to the CPU, and support for better memory overclocking, the X570 chipset is AMD's flagship offering for the Ryzen 3000 platform. Or may be not.
We might see AMD offering a new X590 platform for enthusiast Ryzen 3rd generation CPUs such as the Ryzen 9 3900X and the Ryzen 9 3950X. The first hints for X590 started appearing after Yuri Bubly (@1usmus), the developer of the DRAM Calculator for Ryzen tool, teased "AMD X590 and more possibilities coming soon... ;)" on Twitter of what is possibly a ROG Crosshair series board. The post was deleted after many publications started talking about the same. Now, a user cm87 on the Computerbase forums posted references to the X590 chipset mentioned in the BIOS file of a Gigabyte motherboard. In the said BIOS file, the X590 is listed next to the X570, but not much information can be immediately gleaned from the file itself.
So what exactly does the rumored new chipset entail? Right now, our guess is as good as yours. However, there is speculation that X590 will offer even more PCIe Gen4 lanes than what the X570 offers. The X590 could add an additional four PCIe Gen4 lanes that the X570 now uses for CPU interconnect. Last year, AMD had reportedly planned to introduce a Z490 chipset with added PCIe lanes but that got shelved due to some reasons. The X570 is a premium chipset in itself so it remains to be seen how OEMs will be pricing X590 boards when they come to market.
Remember all this is still speculation at this point so we aren't quite sure as to when OEMs would be announcing enthusiast X590 boards or what the exact specifications of the chipset are. We'll be sure to keep you updated on these developments so stay tuned.
