AMD's 4GB RX 9050 Lags 8GB Version by 37% in Tests

New benchmarks reveal AMD's entry-level 4GB Radeon RX 9050 is significantly slower than its 8GB counterpart due to reduced memory bandwidth.
Key points
- The 4GB Radeon RX 9050 averages 78 FPS at 1080p, while the 8GB model reaches 107 FPS.
- The 4GB card has half the memory bandwidth and Infinity Cache of the 8GB version.
- The 4GB model is sold only in prebuilt systems, with one example listed at $889.99.
Fresh benchmark results have revealed a significant performance gap between two versions of AMD's new entry-level graphics card. The Radeon RX 9050 with 4GB of memory is running roughly 37% slower than the 8GB model in current gaming tests. This disparity stems from the 4GB card having half the memory bandwidth and cache, a trade-off that severely limits its capability in modern titles.
The data comes from two independent hardware channels that tested the card within prebuilt systems, as AMD does not sell the 4GB version directly. While the 8GB model achieved an average of 107 frames per second at 1080p resolution, the 4GB variant managed only 78 FPS. Even at the lowest graphical settings, the performance gap remained substantial, indicating that the memory configuration is the primary bottleneck rather than raw processing power.
Memory Constraints Drive Performance Gap
Both versions of the RX 9050 share the same 1,024 stream processors and similar boost clock speeds, meaning the core silicon is identical. The difference lies entirely in the memory subsystem. The 4GB model uses a 64-bit bus with 144 GB/s of bandwidth and 16 MB of Infinity Cache. In contrast, the 8GB version doubles these figures. For contemporary games that rely heavily on video memory, this reduction effectively caps the frame rate regardless of how fast the chip itself runs.
OEM Exclusive Availability and Pricing
This specific 4GB configuration is not available to consumers as a standalone retail product. AMD has stated it was developed exclusively for partner systems aimed at the entry-level market. The card was first spotted in a CyberPowerPC Gamer Master prebuilt at Best Buy, listed at $889.99. Reports indicate that XFX is manufacturing the board, suggesting it may appear in other prebuilt systems as well. However, buying a prebuilt system to access this specific GPU is a significant premium over building a custom PC with the 8GB version.
Limited Data and Market Context
While the current samples from Hardware Unboxed and Toasty Bros are consistent, they represent a small dataset. TechPowerUp notes that more independent testing is needed before drawing final conclusions on the card's long-term viability. Nevertheless, launching a 4GB graphics card in 2026 raises questions about its practicality for gaming. With modern titles increasingly demanding more than 4GB of VRAM even at lower resolutions, the performance penalty observed in these tests suggests that the 8GB model offers a far better value proposition for gamers seeking entry-level hardware.
