„Radeon RX 5300 XT“ ir „AMD B550“ mikroschemų rinkinys ateis į OEM sistemas spalio mėn



HP has listed new desktop consumer prebuilts that use previously unannounced hardware from AMD, namely the Radeon RX 5300 XT graphics card and the B550 chipset. B550 has been expected for a while - it's a lower-cost chipset for Ryzen 3000 'Zen 2' processors with reduced feature set. HP calls the chipset 'AMD Promontory B550A' in their sheets which seems to be designed and produced by ASMedia (unlike X570, which is a fully AMD in-house design). One of the major differences between X570 and B550 is that the latter has no support for PCI-Express 4.0, which won't matter one bit in its target segment. This move not only reduces chipset cost, it also drives down the cost of motherboards significantly, as the more stringent signal integrity requirements for PCIe 4.0 won't apply here.

Nors girdėjome gandų, kad AMD dirba prie mažesnio lusto, skirto jų „Navi“ architektūrai („Navi 12“ ir „Navi 14“), neaišku, ar „RX 5300 XT“ iš tikrųjų remiasi „Navi“, ar tai bus dar vienas prekės ženklas - mes to nenorėtume Nenustebkite, jei „Polaris“ vėl sugrįš. Abi sistemos yra vertinamos už 699 ir 899 eurus, o lentynos bus laukiamos spalio 8 d.
