AMD's Infinity Cache is the MVP of the RX 6000-series, and it's only going to get better

Introduced with the RDNA 2 architecture, Infinity Cache is a new cache system that operates alongside the GDDR6 memory interface within both the RX 6800 XT and RX 6800. It’s a pretty big deal for AMD, too, with its engineers telling us it is the key to unlocking gaming performance from 1080p to 4K where it would otherwise have been saddled with a massive and power-hungry alternative.

Sitting just off the side of the main cluster of compute cores within AMD’s Navi 21 GPU, the Infinity Cache essentially acts as a small yet effective memory store. It’s situated between the smaller L1 and L2 caches, also on the GPU itself, and the wider GDDR6 and DDR4 memory off-chip, on the PCB and in the PC itself.
