AMD will launch Radeon RX 7000 series graphics cards this year, equipped with Navi 3x series GPUs based on the RDNA 3 architecture. There have been rumors that the AMD Radeon RX 7000 series graphics cards are divided into two parts, the RDNA 3 architecture and the RDNA 2 architecture, of which the RDNA 3 architecture has only three GPUs: Navi 31/Navi 32/Navi 33.

The top-of-the-line Navi 31 has had a lot of news since last year. It seems that the specifications are very high, and it even makes people feel a little incredible. Recently, Twitter user @greymon55 confirmed again that the top model equipped with Navi 31 is AMD Radeon RX 7950 XT. The Navi 31 core used has 15360 stream processors, the Infinity Cache is 512MB, it is equipped with 32GB of GDDR6 video memory, the bit width is 256 bits, the rate is 21 Gbps, and the power consumption reaches 500W. The clock of the new flagship graphics card is said to reach 2.5 GHz, providing 38.4 TFLOPs of FP32 computing performance.

According to past news, Navi 31 will use MCM multi-chip packaging, using a 5nm process to manufacture GCD (graphics computing chip) and a 6nm process to manufacture MCD. AMD will make changes to the original structure, no longer the original CU computing unit, and will use WGP as the main computing module. At the same time, the Infinity Cache of Navi 31 will turn to the design of a 3D stack and will be added to the MCD chiplet, which is similar to the principle of using 3D V-Cache on the Zen 3 architecture.

In addition, it is rumored that AMD does not plan to introduce the 16Pin 12VHPWR interface on the Radeon RX 7000 series. The reason is that AMD believes that the interface is not stable enough, and it is also possible that AMD has completed the design of the Radeon RX 7000 series before the interface standard is determined.
