Moore’s Regulation Is Lifeless
Rumor has it that AMD might have determined to not launch any high-end GPUs within the subsequent era of graphics playing cards, that means RDNA 4. Nevertheless, this freshly leaked diagram provides us some perception into what may have been — or maybe, what can be — if AMD’s finest graphics card of the following era was made. It seems that AMD’s next-gen structure is much more advanced than RDNA 3.
The diagram comes from YouTuber Moore’s Regulation is Lifeless, who, as at all times, cites his personal nameless sources. It’s solely a partial diagram, however even that fast look into the structure of RDNA 4 tells us rather a lot. Whereas unsure which GPU that is, Moore’s Regulation Is Lifeless refers to it as Navi 4C, and all indicators level to it being AMD’s prime GPU for the following era. Nonetheless, it’s unclear if this new naming conference refers to Navi 41 or maybe Navi 42, as Navi X and Navi M have additionally been talked about lately.
Trying on the diagram reveals a big package deal substrate with 4 dies. One is a Multimedia and I/O die (MID), whereas the opposite three are Lively Interposer Dies (AIDs), the latter of which appear to have the ability to home as much as 3 Shader Engine Dies (SEDs). Moore’s Regulation is Lifeless additionally speculates that the reminiscence controller dies are lacking from this diagram, however they need to be current on either side — nevertheless, it’s unclear what number of precisely we’d be taking a look at right here. Lastly, Infinity Cache dies would additionally most likely be current.
All in all, the Navi 4C GPU would have had anyplace between 13 to twenty chiplets. This could have meant an enormous change from the current-gen chiplet design, as AMD appears to have cut up it and added extra exterior interconnects. We’re nonetheless seeing multiples of the identical elements, comparable to reminiscence cache dies (MCDs), however as Moore’s Regulation Is Lifeless notes, there are numerous extra of them now, including to the complexity of this new GPU structure.

This complexity may spell good issues for next-gen GPUs, but it surely additionally makes all the design and manufacturing course of much more tough. AMD might have bitten greater than it may chew with such a decent timeline, assuming that RDNA 4 is round a yr away from now. It might be that this design can be shelved till RDNA 5 — it appears unlikely that AMD will stop the GPU race completely and accept the mainstream section, though that might make some sense, too.
It’s onerous to even start to estimate the enhancements introduced on by this experimental structure. AMD selected to not compete towards Nvidia’s finest GPU this time round, and plenty of rumors level to it opting out of constructing high-end GPUs within the subsequent era. Nevertheless, by the appears of it, as soon as it does come again to creating beastly GPUs, AMD may give Nvidia one thing to fret about.
