Prominent leaker _rogame has shared a document (via VideoCardz) that reveals the purported shader engine (4), shader arrays per shader engine (2), and compute units per shader array (10) counts for AMD’s upcoming “Sienna Cichlid” GPU, otherwise known as “Big Navi.” Based on some simple math, these specifications suggest that red team’s next flagship Radeon card could boast 80 Compute Units (4 x 2 x 10), which would imply 5120 Stream Processors (80 x 64 cores).

In comparison, AMD’s Radeon RX 5700 XT only features 40 Compute Units and 2560 Stream Processors, so those earlier rumors of Big Navi offering twice the performance may actually be correct. There’s a possibility that the die will be cut down, resulting in a card with 72 Compute Units, but that would still be a pretty substantial improvement from the current flagship.
