AMD Confirms OEM‑Only Radeon RX 9050 4 GB With Halved Memory Subsystem

The company published product and driver details showing the 4 GB card was built for a specific OEM and uses a much narrower memory design that could cut gaming performance in new prebuilts.

AMD confirms specs of RX 9050 variant with only 4GB of VRAM

Overview

  • AMD published product-page details and added driver support on Friday confirming a Radeon RX 9050 4 GB variant that is OEM‑only and not intended for retail.
  • The 4 GB model keeps the same GPU compute (Navi 44, 16 CUs, 1,024 shaders) but uses 18 Gbps GDDR6 on a 64‑bit bus for 144 GB/s of bandwidth and a 16 MB Infinity Cache.
  • Those specs halve the 8 GB RX 9050’s memory bus, bandwidth, and cache compared with the 128‑bit, 288 GB/s, 32 MB configuration used on the retail 8 GB card.
  • Reviewers and outlets warn that 4 GB of VRAM plus a 64‑bit bus will likely cause significantly worse performance in modern games and limited headroom for settings or higher resolutions.
  • The move reflects OEM pricing and supply pressures and could let builders ship cheaper systems, but it risks poor gaming experiences in new prebuilts as the industry treats 8 GB as the 2026 baseline.
