AMD Allegedly Working on Next-Gen GPU with as many as 13 Chiplets, Coming in 2024?

AMD’s Radeon Division is busy cooking up all kinds of monstrosities. The chipmaker is allegedly working on a massive 13-chiplet GPU featuring up to four GCDs (Graphics Compute Dies) and nine Memory Complex Dies (MCDs). This would result in an absolutely maniacal configuration packing close to 20,000 shaders and 36GB (?) of GDDR6/7 memory alongside a gaping 512-bit+ bus. Now, these specs do sound a little over the top and probably are but we’re almost certainly looking at a next-to-next-gen GPU that won’t pop up in retail before 2024.

Update: It looks like it’ll be a 3D stacked V-Cache variant of Navi 31.

This is probably an RDNA 4 design with additional architectural upgrades. The process node will likely remain the same or be replaced by the N3 3nm or the N4 4nm process depending on how the volume production progresses. The Infinity Cache (L3) ought to get an upgrade as well, though not by much. The bulk of the performance improvements will come from process and packaging enhancements. The graphics core shouldn’t undergo much of a change either as RDNA 3 is already a massive overhaul.
