AMD introduced its RDNA 3.5 GPU. The new GPU aims to increase mobile gaming performance. Details and technical improvements are in our article.
At an event held in Los Angeles last week AMDexplained in more detail all the changes it brings with the Zen 5 CPU architecture. The chip giant also briefly revealed the innovations in RDNA 3.5 – a “partial improvement” that is “bolted” to the existing graphics processor design. In short, everything mobile game performance regarding increasing.
AMD’s RDNA 3.5 GPU Focuses on Improving Mobile Gaming Performance
The updated design was introduced by AMD chief technology officer Mark Papermaster, who began by noting that the changes were a result of a collaboration with Samsung, which licensed AMD’s graphics technology for its Exynos line of smartphone and tablet processors.

RDNA 3.5 is here to improve some of the performance bottlenecks that AMD’s GPUs face when used in low-power, low-shader-count configurations. These improvements are specifically aimed at the integrated Radeon GPUs in its mobile APUs, which are used in laptops and handheld gaming PCs. For example, a Radeon RX 6400 can use up to 54W of power, while the GPU in the Asus ROG Ally needs to consume 80% less power.
One of the biggest improvements Papermaster noted was doubling the texture sampling capacity of each CU. In RDNA 3.5, each CU hosts eight texture units instead of four. This allows mobile GPUs to grab twice as many texels per clock cycle, compensating for their lower core clocks.
AMD’s presentation slides state that this doubling is only for “a subset of the most common texture sampling operations.” This is supported by other performance-boosting features like memory management improvements and vector-intensive operations. For example, operations that involve multiple reads of data from vector register files are also improved in RDNA 3.5.
RDNA 3.5 also features better memory compression algorithms, and the iGPU’s memory controller is optimized for portable gaming PCs and laptops. To summarize, AMD aims to deliver more performance with the same or less power on mobile devices with RDNA 3.5.
