AMD Confirms Radeon RX 9050 4GB: Navi 44, Halved Memory Bus, Bandwidth, and Infinity Cache
AMD has launched the Radeon RX 9050 for the entry-level market, based on the Navi 44 chip. Initially only an 8GB version was listed, but a driver update (Adrenalin 26.8.1) added support for a 4GB variant. The 4GB model halves memory capacity, bus width, and bandwidth compared to the 8GB version. Both have 1,024 stream processors, a 1,920MHz game clock, and a 2,600MHz boost clock. The 4GB uses a 64-bit bus, the 8GB uses 128-bit, both with 18Gbps GDDR6. Outputs include one HDMI 2.1b and two DisplayPort 2.1a.
In late July 2026, AMD launched the Radeon RX 9050 for the entry-level market, featuring the Navi 44 chip. Initially, only the 8GB memory version was officially detailed. With the update to the AMD Software Adrenalin Edition 26.8.1 driver, support for the 4GB memory version was added, and the corresponding product page went live simultaneously. The two versions share the same basic specifications, with the main difference being the memory: the 4GB version halves the memory capacity, bus width, and bandwidth compared to the 8GB version.
In terms of specific specifications, the Radeon RX 9050 has 1,024 stream processors, a game clock of 1,920MHz, and a boost clock of 2,600MHz. The 4GB version uses a 64-bit bus width, while the 8GB version uses 128-bit, both equipped with GDDR6 memory at 18Gbps. Display outputs include one HDMI 2.1b and two DisplayPort 2.1a ports.
