AMD Navi 31 flagship multi-chip GPU showed up in photos ahead of the announcement

A photo of AMD Navi 31 GPU based on RDNA 3 architecture, which will form the basis of higher-end Radeon RX 7000 graphics cards appeared at Angstronomics' disposal.
Recall that the official announcement of the latter will be held this evening.Image source: AMDThe presented photo of Navi 31 GPU confirms the use of chiplet design.
In the photo you can note the main graphics chip Graphics Chiplet Die (GCD) in the center and six auxiliary crystals Memory Chiplet Dies (MCD).Image source: AngstronomicsThe same source previously reported the alleged specifications of the Navi 31 GPU.
So, the main GCD chip with an area of about 308 mm2 contains 48 WGP (Workgroup Processors) blocks.
Each WGP has two Compute Units (CUs).
Thus, the total number of CUs in the chip is 96.
And the total number of Arithmetic Logic Units (ALUs or Area Stream Processors) within the 96 CU's would be equal to 12,288 units.The area of one MCD chip, in turn, is about 37.5 mm2.
The total area of the GCD with all the MCD chips is approximately 533 mm2.
The area of the entire GPU package is 2612 mm2 (dimensions 55 × 47.5 mm).
Each MCD contains 16 Mbytes of AMD Infinity Cache.
Thus, Navi 31 GPU will get 96 MB of Infinity Cache, which is less than the same Navi 21 (128 MB) that powers Radeon RX 6900 XT/6950 XT.It is also reported that Navi 31 GPU supports 384-bit memory bus with up to 24 GB of GDDR6 memory at 20 Gbit/s per pin.
This chip is expected to be the core of the Radeon RX 7900 XTX graphics gas pedal.
Expected specifications of AMD Navi 31, Navi 32 and Navi 33 graphics processors.
Image source: VideoCardzIt is expected that during today's presentation AMD will present only the senior models of Radeon RX 7000 gas pedals based on Navi 31.
Models based on Navi 32 and Navi 33 GPUs will probably be announced later.
However, we will be able to find out the exact information in a few hours.
