AMD Radeon "Navy Flounder" Features 40CU, 192-bit GDDR6 Memory

AMD uses offbeat codenames such as the "Great Horned Owl," "Sienna Cichlid" and "Navy Flounder" to identify sources of leaks internally. One such upcoming product, codenamed "Navy Flounder," is shaping up to be a possible successor to the RX 5500 XT, the company's 1080p segment-leading product. According to ROCm compute code fished out by stblr on Reddit, this GPU is configured with 40 compute units, a step up from 14 on the RX 5500 XT, and retains a 192-bit wide GDDR6 memory interface.

Assuming the RDNA2 compute unit on next-gen Radeon RX graphics processors has the same number of stream processors per CU, we're looking at 2,560 stream processors for the "Navy Flounder," compared to 80 on "Sienna Cichlid." The 192-bit wide memory interface allows a high degree of segmentation for AMD's product managers for graphics cards under the $250-mark.

AMD "Sienna Cichlid" Could be "Big Navi"

Linux kernel patches reference an AMD "Sienna Cichlid" GPU, which Phoronix believes could be the fabled "Big Navi" GPU. We know this is a GPU and not a headless CDNA scalar processor as the patches include code for VCN 3.0 video encoding capabilities (RDNA2's media engine), and DCN3 (RDNA2's display engine), which constitute bulk that AMD could get rid of on CDNA chips. The unusual internal codename could reference AMD's next generation RDNA2 architecture based flagship GPU, armed with 80 compute units (5,120 stream processors), Radeon Intersection Engines (accelerate real-time ray-tracing). The codename comes across as unusual, but AMD does tend to use wacky internal codenames to detect sources of leaks.
