Navi 24 (Radeon RX 6400/6500) is created directly on the 6nm process

With CES approaching, a decent package of GPU information has leaked Navi 24 and the Rade 65X XT and RX 6400 that will be created on it. AMD appears to have used the delays in this GPU to move production to the 6nm process. Although this is not a big shift compared to 7nm production, the wafer can produce about 20% more chips, which is convenient (a few percent higher energy efficiency is not to the detriment, but the generation difference can not be called).

Compared to previous information, the Radeon RX 6500 XT will not be equipped with 14GHz GDDR6, but 16GHz chips, which gives room for a few percent extra power. Another change concerns TDP. It will not be 75 watts for the Radeon RX 6400 and 120 watts for the Radeon RX 6500 XT, but 53 and 107 watts.

Another novelty is that AMD from Navi 24 starting with, it also plans to report effective data throughput, including the Infinity Cache effect. For the Radeon RX 6400 it will be 216 GB / s and for the Radeon RX 6500 232 GB / s. Both cards (at least the reference designs) have two graphic outputs: DisplayPort (probably 1.4) and HDMI (probably 2.1). Radeon RX 6500 XT counts with 6pin power connector and two-slot cooling, Radeon RX 6400 is single-slot and low-profile.

Zleva: Navi 21, Navi 22, Navi 23 and Navi 24

The Radeon RX 6500 XT is expected to be released on January 19, the Radeon RX 6400 apparently two months later, but so far it looks like the slower product will only go to OEM distribution in March.
