AMD Radeon RX 5300 XT and B550 chipset inbound: Navi 14 launching on October 8?
German retailer Alternate may have confirmed the nomenclature of a new Radeon RX 5300 series, which is possibly one of AMD's much-anticipated challengers to the NVIDIA GeForce GTX 16 series. Initially reported by ComputerBase, two pre-built HP desktops have gone live on Alternate.de, which both feature the hitherto unknown Radeon RX 5300 XT. You can view the full datasheets for the M01-F0017NG and TP01-0006ng by clicking on their names. Incidentally, these machines will cost €699 and €899 respectively, but please keep in mind that this includes taxes that will not necessarily be applied in other regions like the US. Alternate.de currently states that both machines will start shipping on approximately October 8.
According to both datasheets, the RX 5300 XT will have 4 GB of GDDR5 VRAM, making it comparable with the Polaris-based AMD Radeon 530 in some senses. However, that does not mean that AMD is planning to re-hash its Polaris architecture using its RX branding. On the contrary, PCGamesN claims that AMD will base the RX 5300 series on its Navi 14 architecture. AMD uses Navi 10 chips for its RX 5700 series, so with Navi 12 and Navi 14 on the way PCGamesN has inferred that the latter will make its way into the RX 5300 series.
This would also be consistent with what said Radeon VP Scott Herkelman noted in his "double jebait" interview with Hothardware in July. Herkelman stated that the RX 5700 XT series was the start of "a consistent model naming scheme for the five to ten years", with the first digit indicating the generation of RX GPU and the second being its position within the company's product stack. Meanwhile, AMD will split series into '00' or '50', with 'XT' denoting that it is a top bin chip. Hence, the RX 5300 XT will be the top of AMD's budget RX line, which it may eventually supersede with an RX 5350 XT.
The two listings also confirm that a B550A chipset is on the way, which leaker @momomo_US claims will be AMD's new mainstream chipset that will support four lanes of PCIe 3.0. It will also support eight lanes of PCIe 2.0, two USB 3.2 Gen2 connections and six USB 2.0 connections. The chipset will be able to run dual GPUs too.
