momomo_us has spotted an interesting trademark filed by AMD last month that alludes to a new technology dubbed “Infinity Cache.” The document suggests that Navi 2X GPUs (i.e., Radeon RX 6000 Series) could be outfitted with a special memory cache for increased performance.



This is cool news for those of you who have bought into the popular theory that red team’s flagship RDNA 2 GPU (Radeon RX 6900 XT?) will only sport a 256-bit memory bus, which critics believe could hamper performance. (In comparison, NVIDIA’s GeForce RTX 3080 flaunts a 320-bit memory interface width.)

The link above is the trademark (for "Infinity Cache")

I believe the patent is in below link

incidentally, the patent says "ADAPTIVE CACHE RECONFIGURATION VIA CLUSTERING" (& not "Infinity Cache")

it is basically pooled L1 cache to avoid fetches to L2 cache

As per a paper by AMD affiliated researchers, this method gives upto ~25% benefit in best case & 4% degradation in worst case.

the video below explains it in simple terms.
