AMD is expected to unveil the Radeon RX 7800 series graphics cards in the fall, expected to feature the Navi 32 GPU. Expectations YouTube channel Moore’s Law is Dead, AMD has also created a smaller version of the flagship GPU Navi 31 used in the Radeon RX 7900 XT and RX 7900 XTX. The source shared an image of this GPU which has a compact package.
In the provided photo (below), the GPU contains six MCDs with cache and memory controllers. The same configuration is used in the standard version of the Navi 31. However, with the compact version of the GPU, only four MCDs are active in the photo. In addition, the chip itself with the substrate has dimensions of 40 × 40 mm (total area 1600 mm).2), while the standard version of the Navi 31 measures 55 × 47.5 mm (total area 2612.5 mm).2). As the source points out, the compact Navi 31 supports a 256-bit memory bus. This allows you to take advantage of configurations with 4, 8, 16 and 32 GB of memory. From previous leaks it is known that the card will have 16 GB of memory.
According to Moore’s Law is Dead, AMD sent samples of the compact version of the Navi 31, which is the same size as the younger Navi 32, to graphics card manufacturers so they could prepare new graphics cards for launch. According to the source, the older Radeon RX 7800 XT can only get a stripped down compact Navi 31, while the regular Radeon RX 7800 and other mid-range Navi 32s will come in different configurations with the same chassis dimensions – 40×40 mm.
It is assumed that such a compact version of the Navi 31 can also be used in laptops, which will allow AMD to increase competition in this segment. For example, the chip can create a mobile Radeon RX 7900M XT that can compete directly with NVIDIA’s mobile GeForce RTX 4080.
