AMD Navi 32 GPU pictures: GCD x1 and MCD x4

AMD has unveiled two GPUs based on the RDNA 3 architecture, the Navi 31 and Navi 33, which correspond to the Radeon RX 7900 series and Radeon RX 7600 graphics cards for the desktop platform, both of which are now commercially available. Recent reports suggest that the Radeon RX 7800 XT, equipped with Navi 32, will be released between the end of the third quarter and the beginning of the fourth quarter in 2023, with a price point similar to that of the GeForce RTX 4070.

In late May of this year, Dr. Lisa Su, CEO of AMD, granted an interview to the media in which she discussed AMD’s past and future trajectory. Recently, Twitter user @AnhPhuH noticed that the silhouette of the AMD Navi 32 GPU appears to be featured in a segment of the interview video.

From the screen capture, and considering the Navi 31 for comparison, the appearance of the GPU chip aligns well with the rumored specifications. Like the Navi 31, the Navi 32 adopts a Multi-Chip Module (MCM) design, featuring a 5nm Geometry Computation Die (GCD) and four 6nm Memory Computation Dies (MCD), with a chip area of approximately 348 mm².

The Radeon RX 7800 XT, armed with the Navi 32, will utilize all computation units fully, encompassing 60 Compute Units (CU), or 3,840 stream processors. It will boast an Infinity Cache of 64MB and 16GB of GDDR6 memory. The memory bandwidth will be 256-bit, and the memory speed should be around 20Gbps. Rumors suggest the gaming frequency and boost frequency hover around 2.6GHz and 2.8GHz respectively, while the FP32 computational performance is pegged at 43 TFLOPs, and the total power consumption of the card is approximately 280W.
