AMD has updated its documentation page for the late-July launch of the Radeon RX 9050 graphics cards, which include two models: one with 4 GB and another with 8 GB of GDDR6 memory. Both cards feature 1,024 Streaming Processors across 16 Compute Units and can boost up to a 2.6 GHz clock speed. However, the lower-end GPU has only 4 GB of GDDR6 memory on a 64-bit bus, resulting in a memory bandwidth of 144 GB/s, which is significantly lower than the 8 GB version. The 8 GB version of the Radeon RX 9050 uses 8 GB of GDDR6 on a 128-bit bus, providing a memory bandwidth of 288 GB/s, doubling the throughput.

Another difference lies in the Infinity Cache within each GPU die. The 8 GB edition has 32 MB of Infinity Cache, while the 4 GB edition has only 16 MB. Initially, the listing for the 4 GB edition did not reveal the difference in Infinity Cache size, but AMD's documentation confirms it. Naturally, this will result in some performance differences, as larger cache buffers tend to improve performance significantly.

AMD confirmed that the 4 GB version will be exclusively for OEMs and system integrators to include in their low-end PC configurations. For gamers, the 8 GB edition will be marketed as the entry-level RDNA 4 GPU and is expected to be priced at $279, making it the most affordable card AMD currently offers. There appear to be no Made by AMD (MBA) designs, as add-in board partners are handling the launch.
