A couple of renders of what a possible AMD Navi 4X Halo GPU based upon the RDNA 4 architecture have been published which should us a glance of what this flagship gaming chip might’ve been.
AMD’s High-End Navi 4X Halo GPU Featuring The RDNA 4 Architecture Appears In Conceptual Renders
You may have heard the rumor of AMD canceling its high-end RDNA 4 GPUs and focusing on the mainstream SKUs such as Navi 43 and Navi 44. There were likewise rumors that the high-end chips consisted of SKUs such as the Navi 4C and Navi 4X which were expected to go all out with an MCM style.
Now based upon some concepts of what this high-end chip may’ve been, Twitter fellow, Olrak29, has actually posted a couple of diagrams of the chip which have further gotten full-on renders by @creper9000. Do note that these are simply conceptual images and might or may not represent the final product.

2 of 9 Beginning with the first image, we have a standard plan that is composed of 3 main parts, the AID, SED(Shader Engine Die), and the MID( Multimedia & I/O Die).
According to the early information revealed by Moore’s Law is Dead, the AID and MID would have been included on the base pass away & SEDs would’ve been included on the AIDs in groups of 3. The base-layer would’ve included a total of 3 AID’s an d a single MID adjoined with a Die-to-Die interconnect and each AID would have brought three SED’s and linked through the very same interconnect material. The AIDs for Navi 4X GPUs based upon the AMD RDNA 4 graphics architecture might’ve included the Infinity Cache, interconnects, and GDDR PHYs. The TSVs to connect the SED’s to the AID’s would’ve likewise been on the AID portion of the chip. As for the MID, it might’ve carried the VCN, DCN, PCIe & I/O of the chip. The physical plan of the whole Navi 4X Halo GPU is stated to have actually been extremely

2 of 9 Based on all of the information, Creper9000 developed some nicely rendered images of the entire chip which undoubtedly looks gigantic & shows us what the future may hold for the MCM technology. Early renders of the AMD Navi 3X “RDNA 3” GPU lineup were likewise very close to the last retail chips however if the high-end Navi 4X GPUs are indeed cancelled, then they may only reside in the type of renders and we can expect a similar MCM solution in a future generation.
While this is still a rumor and nothing has officially been verified by AMD as of yet, the RDNA 4 lineup is relatively only going to get Navi 44 and Navi 43 SKUs with the Navi 42 and Navi 41 chips most likely out of the formula (in the meantime). The lineup is expected to launch at some point in 2024so there’s still a lot of time left in launch and the business is absolutely refrained from doing with its RDNA 3 family yet which will be getting more updates later this fall.
