AMD’s unreleased Navi 24 leaks

Released on the desktop side as the Radeon RX 6400 and RX 6500 XT, the Navi 24 is manufactured using TSMC’s N6 process, according to VideoCardz.

AMD’s RDNA2 graphics chip family is known to include at least one other unpublished chip. Now VideoCardz has gotten new information about the upcoming Navi 24.

Based on the images, VideoCardz has pre-acquired parts of AMD’s Navi 24 slide pack. The images show the upcoming graphics circuit both alongside other members of the same family and larger in their own image. The circles in the news main image are from left to right Navi 21, Navi 22, Navi 23 and Navi 24.

A close-up of the Navi 24 shows a total of 16 Compute Units, which would mean 1024 stream processors. The memory controller has shrunk to 64-bit and has 16 megabytes of Infinity Cache. VideoCardz estimates the chip size to be approximately 141 mm2.

Perhaps the most interesting detail, however, is the alleged manufacturing process of the circuit. According to VideoCardz, unlike other RDNA2 graphics chips, the Navi 24 would be manufactured using TSMC’s N6 manufacturing process. The N6 is designed to be an easy process that is compatible with the N7 in terms of design rules, but AMD has not mentioned the use of a different process, at least in official contexts.

AMD is expected to release the Navi 24 graphics chip and the Radeon RX 6500 XT based on it in January. In addition, the circuit will reportedly be seen as a portable as well as a more prestigious version of the RX 6400 used by OEMs.
