One of the biggest rumors surrounding AMD’s upcoming lineup of Radeon RX 7000 Series graphics cards is that some of the models will feature an RDNA 3 GPU with a brand-new, MCM design, one that leverages multiple chiplets for improved efficiency and/or performance. The rumor mill is now claiming that this may not be the case, with new purported specifications released this week that are not only toned down but indicate that Radeon fans may have a longer wait ahead of them before they can get a GPU with a dual chiplet design from red team. AMD’s Navi 31 GPU will feature 12,288 total shaders, all of which are housed on a single GCD, according to documents shared by Red Gaming Tech.

As @kopite7kimi pointed out, old info from last Oct is outdated 😉
– 20% less WGP
– no more double GCD for N31/N32
– 6 MCD for N31 = 384 MB IF$
– 4 MCD for N32 = 256 MB IF$https://t.co/rj2G2gi9CU pic.twitter.com/yDqeTTdSAT
Where once it was a 92 TFLOP beast with some 15,360 shaders, arrayed across a pair of graphics compute dies (GCDs), those specs have already been toned down to 72 TFLOPs and 12,288 shaders. Now we’re hearing rumours that all the noise about a dual graphics chiplet design were erroneous, and the reality of the multi-chip design is more about the floating cache than extra compute chips.
The latest video from Red Gaming Tech, seemingly corroborated across the Twitter leakers, is suggesting that the entire 12,288 shader count is going to be housed on a single 5nm GCD, with a total of six 6nm multi-cache dies (MCDs) arrayed around it, or possible on top of it.
