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.

AMD RDNA 2 Navi 23 GPU Powered Radeon RX GPUs To Feature 32 MB Infinity Cache, A Quarter of Navi 21's Infinity Cache Pool

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.

AMD RDNA 2 Powered Navi 23 GPU For Radeon RX 6000 Graphics Cards

The patch confirms the Infinity Cache size which is listed as a level-3 cache (L3) for all three RDNA 2 GPUs that will be coming to desktop PCs. The Navi 21 GPU 'Sienna Cichlid' features the biggest size of 128 MB Infinity Cache followed by the Navi 22 GPU 'Navy Flounder' which features 96 MB of L3 or Infinity Cache. The AMD Navi 23 GPU 'Dimgry Cavefish' is going to be the next GPU in the lineup of Radeon RX 6000 series graphics cards and is going to feature 32 MB of Infinity Cache. That's a quarter of the L3 size featured on the Big Navi GPU.

It was previously expected that Navi 23 Radeon RX 6000 GPUs would feature 64 MB of Infinity Cache but that rumor is debunked now. The specifications of the Navi 23 GPU suggest a total of 2048 stream processors & 32 raytracing units inside the GPU package. The GPU will also be packed with 32 MB of Infinity Cache which will help it boost its bandwidth by a huge margin. For memory, we are looking at up to 8 GB GDDR6 capacity that will operate across a 128-bit bus interface and offer pin speeds of up to 16 Gbps. This should bring the total bandwidth to 256 GB/s. The Navi 23 GPU will also be the smallest of the Navi 2X family with a die size reported at around 236mm2.
