In the latest Linux Kernel Patch, AMD has confirmed the Infinity Cache sizes of its upcoming RDNA 2 Radeon RX GPUs based on the Navi 23 SKU. The company has also confirmed that neither RDNA 2 powered Van Gogh nor CDNA 2 powered Instinct accelerators will be featuring its Infinity Cache technology.

The information was spotted by Coelacanth-Dream (via Kepler_L2) and confirms cache sizes & GPU configurations of several RDNA 2 and CDNA 2 GPUs. The AMD Infinity Cache was first introduced on the Radeon RX 6000 series graphics cards featuring the RDNA 2 architecture. The Navi 21 SKU, codenamed Big Navi, was the first to get it but it was followed by the Navi 22 SKU recently & now we are also going to get a third SKU in the form of Navi 23.
