AMD Big Navi has a new Infinity Cache

VideoCardz notes AMD recently filed a trademark application for "Infinity Cache". This is believed to be a new cache technology for the Big Navi GPUs. It's speculated that this is a special cache connected to the memory subsystem, but for more details on how it works we'll have to wait a bit longer. AMD's official Radeon RX 6000 series announcement is scheduled for October 28.

We have been told that AMD Big Navi has a relatively small memory bus of 256-bit and it is currently uncertain how the special cache works. The alleged AMD Radeon RX 6900 graphics card would therefore feature 16GB GDDR6 256-bit memory paired with Infinity Cache. This, of course, would be the highest SKU in the lineup.
