The new slides detail AMD chiplet technology featured in RDNA3 architecture. They explain the decision behind moving the Infinity Cache outside the GPU die. We also learn that the Infinity Links, the interconnect technology between the memory and GPU is operating at 9.2 Gbps. This is 10 times higher bandwidth density compared to Ryzen and EPYC IFOP (Infinity Fabric On-Package) approach. AMD further claims that the peak bandwidth between MCDs and GCDs is at 5.3 TB/s.

 ...I wish they would apply that to AM5, and also improve the memory controller to get much faster and catch up with Intel's 13th gen...I might even buy an AM5 then (or earlier if/when they release a 7950X3D ). Speaking of memory controllers, Level1Techs had an interesting observation re. the new Epyc Genoa (up to 96C /192 T, DDR5, based on the Zen 4 chiplet) having a better memory sub-system - and I'm not talking about sheer bandwidth of the 12 channels per below. Possibly some new microcode that hasn't made it to the Ryzen 7K yet...
