The chiplet revolution is coming to Radeon with RDNA 3

AMD's Navi 31 GPU is reportedly a 7-chiplet gaming behemoth

It looks like big changes are coming to AMD Radeon with the launch of the company's RDNA 3 architecture, as rumour has it that it will deliver a tremendous performance leap over today's RDNA 2 graphics chips by becoming the first gaming graphics cards to be built using multiple chiplets.

With RDNA 3, AMD should deliver their usual generational leap in performance from new architectural innovations, with some claiming that AMD has made major strides with RDNA 3's ray tracing performance. Beyond this, AMD's move to GPU chiplets will allow Radeon to scale their graphics performance to new heights by fusing multiple graphics compute dies to create something stronger (and cheaper) than a standard monolithic GPU design.

The leaker @Greymon55 has reported that AMD's Navi 31 GPU will be built using two 5nm Graphics Complex Dies (GCDs), four 6nm Memory Complex Dies (MCDs), and a single interconnect controller. In total, Navi 31 is a graphics card that is made using seven chiplets.

AMD's Navi 31 Graphics Complex Dies are expected to feature more stream processors than AMD's flagship Navi 21 silicon. With two of these chiplets inter-connected, AMD's RDNA 3 flagship could be more than two times more powerful than a Radeon RX 6900 XT. With RDNA 3, AMD has the potential to redefine the high-end GPU market.

AMD's RDNA 3 GPU chiplets will reportedly be made using TSMC's 5nm and 6nm lithography nodes. Currently, AMD has not officially revealed what lithography nodes their RDNA 3 graphics cards will use, aside from stating that they would use an "advanced node" on their GPU roadmap.

With their RDNA 3 architecture, AMD has created a chiplet-based GPU that can function as a singular graphics card in gaming workloads. This is no small feat, and could herald a new high performance era of high-end graphics cards. If AMD is the first manufacturer to achieve this feat, they could massively outperform their competitors within the gaming market, assuming that their competitors don't have MCM-based next-genration graphics cards in the near-term future.

AMD expects to launch graphics cards based on their RDNA 3 architecture in the second half of 2022.

I could see this coming a few years back with Ryzens introduction, Monolithic designs while they have their place are far too expensive and that expense is loaded off onto the customer, Hopefully this means we may see more sane prices going forward. Quote

I think we should be so lucky, one thing i will say is that its rare for AMD to hit the ground running with their tech. 1st gen will be a bit of dice roll i reckon. Though efficiency and temperatures should be good.
These will probably need a huge cache compared to the monolithic dies and chew through vram. Quote
