AMD Radeon RX 5300 XT and B550 Chipset Coming in October

HP has listed a few new pre-built desktop PCs which feature unannounced hardware from AMD, which include the Radeon RX 5300 XT graphics card and the B550 chipset. Starting with the chipset, B550 has actually been expected for a while, it is a low-cost option chipset for AMD’s Ryzen 3000 processors with a reduced feature-set. HP calls this chipset “AMD Promontory B550A” in their documentation. The chipset appears to be designed and produced by ASMedia (unlike the X570 chipset, which has a full AMD in-house design). One of the big differences between the two chipsets is that B550 will lack PCI-Express 4.0 support. This move no only reduces cost of the chipset itself, but the prices of the motherboards too.

Now about the RX 5300 XT…we have heard rumors about smaller “Navi” chips (Navi 12 and Navi 14), but it is unclear if the RX 5300 XT is even based on Navi. It could be a “Polaris” rebrand, which we know AMD is pretty famous for doing. The systems are listed for €699 and €899, with availability expected for October 8th.
