AMD held a conference for its investors during which it unveiled details about its next generation of graphics cards. They will be engraved in 5 nm and will inaugurate a chiplet approach. The RDNA4 generation will be engraved in 4 or 3 nm.

AMD wanted to give indications on RDNA3, the architecture of the brand’s next graphics cards. These new Radeons are still expected in the second half of 2022 and will offer a boost in the energy ratio of 50%, a gain similar to that observed between the Radeon RX 5000 and Radeon RX 6000. Enough to offer the best energy efficiency on the market according to AMD , in other words, better energy efficiency than Nvidia’s GeForce RTX 30s.

This interesting leap is accompanied by fine engraving in 5 nm (against 7 nm currently) and above all by “packaging” in the form of chiplets. Thus, as the company already does on Ryzen processors, Radeon graphics cards will be able to integrate several GPU “dies”. This assembly of “dies” on a single physical “chip” will allow AMD to offer significant performance granularity.

The RDNA3 architecture (Navi 3x) will at the same time cause an overhaul of the Compute Unit blocks. Let’s hope for AMD that this will go through a better integration of units dedicated to the acceleration of the effects of raytracing. Finally, the Infinity Cache of the Radeon RX 6000 will be renewed, but in the form of a new generation – no doubt it is above all a question of offering a higher bandwidth than that of the current Infinity Cache.
The sequel was also mentioned, but with very few details. After RDNA3 will obviously come the RNDA4 Navi 4x architecture. Scheduled around 2024 (late 2023-early 2024), this generation will be engraved on a process called Advanced Node. This assumes that it will not be 5 nm, but that AMD is not yet able to specify whether it will be in 4 or 3 nm.
