A few weeks after the official announcement of the Radeon RX 9050 8 GB, AMD has confirmed the 4 GB version.
AMD has finally revealed the full specifications of its Radeon RX 9050 4GB, a few weeks after it appeared in the catalogs of some manufacturers. The card features the same Navi 44 GPU as the 8 GB RX 9050, with 16 compute units, 1,024 stream processors, 16 ray-tracing accelerators, and 32 accelerators dedicated to artificial intelligence. The clock speeds also remain unchanged: 1,920 MHz during gameplay and up to 2,600 MHz in boost mode, delivering 10.6 TFLOPS of FP32 performance and a thermal design power of 92 W. However, it’s in the memory department where the differences become significant. The RX 9050 4 GB features GDDR6 running at 18 Gbit/s, but on a 64-bit bus. Its bandwidth thus reaches 144 GB/s, compared to 288 GB/s for the 8 GB version equipped with a 128-bit bus. AMD didn’t just reduce the amount of VRAM: the Infinity Cache has also been reduced, from 32 MB to 16 MB. In other words, the 4 GB version retains the same theoretical computational potential but has significantly more limited memory resources.

However, this configuration is not intended for retail sale. AMD officially intends the Radeon RX 9050 4GB for the OEM market—that is, for manufacturers that sell complete PCs. The company had already indicated that this version was developed for a partner’s system and that no separate retail release was planned. The RX 9050 8 GB therefore remains the model intended for the consumer market, even though its availability is limited to certain regions. That leaves the question of whether a graphics card equipped with only 4 GB of VRAM is still relevant in 2026. For entry-level setups and 1080p gaming at reasonable settings, this capacity may still suffice for certain uses. But recent games are increasingly demanding in terms of video memory, particularly with more complex textures and graphical effects. And gamers know full well that when VRAM reaches capacity, additional data transfers must occur with system memory, which significantly hampers performance.

The 4GB RX 9050 is therefore likely to quickly reach its limits in the face of the rising demands of PC games. Ultimately, this 4GB Radeon RX 9050 appears to be more of a solution designed to reduce the cost of certain OEM configurations than a true new benchmark in the AMD lineup. The GPU remains identical to that of the 8 GB version, but the cost savings on memory come at the expense of halving the bandwidth and Infinity Cache. This compromise may make sense for system integrators seeking the lowest price, but it risks seriously limiting the lifespan of this small RDNA 4 card.
