AMD’s latest line of RDNA 4 GPUs, which include the Radeon RX 9070 XT, have been available since February. Recently, AMD disclosed that these GPUs are based on a clever modular architecture.

At the Hot Chips 2025 conference, the company shared insights on this modular SoC architecture. The goal is to reduce costs while allowing for diverse GPU configurations. AMD’s design means that they can easily scale up a base GPU to create larger variants.

The base SoC comprises two shader engines and four memory controllers, all integrated with L3 cache and a display engine. Additional shader engines, memory controllers, and cache can be added to this base design to produce various GPU models, streamlining the design and manufacturing process.

Despite the promise of a modular design, AMD has so far released a limited selection of GPUs in the RDNA 4 generation. It remains uncertain if this modular design will lead to a broader range of models, particularly in a competitive market where every GPU model typically varies significantly in layout.

Hopefully, AMD’s recent revelations hint at a future with a wider selection of graphics cards that can effectively compete with NVIDIA’s upcoming offerings.
