THE CRUNCH
AMD's mysterious Radeon RX 9050 4 GB has finally been benchmarked by Hardware Unboxed and Toasty Bros, who bought it inside a CyberPowerPC prebuilt. In an 18-game test at 1080p Low, the 4 GB card averaged 78 FPS with 55 FPS 1% lows, compared to 107 FPS and 78 FPS for the 8 GB model. The 8 GB version is roughly 37 per cent faster, even at the lowest settings. Both cards share 1,024 Stream Processors and a 2.6 GHz core
clock, but the performance gap stems from memory. AMD confirmed the 4 GB model has a 64-bit bus and 144 GB/s of bandwidth, exactly half of the 8 GB card. Toasty Bros also found the card inside an XFX dual-fan unit with a single 8-pin power connector, suggesting ASRock is not the only partner making this model. AMD developed the 4 GB version for a specific partner system aimed at entry-level gaming customers and has no plans to sell it separately. The prebuilt was listed at $889.99, though early results are based on a small sample size.
Launching a card with only 4 GB of VRAM in 2026 is not looking like a great decision so far. The narrow memory bus severely limits bandwidth, which is likely the primary cause of the performance drop. This makes the card a poor choice for anything beyond the lowest graphical settings, even if it is cheap. It remains to be seen if the card will offer enough value to justify its existence, or if it will be quickly forgotten.
