AMD has already officially announced that it will launch the next-generation graphics card in the second half of the year, based on the core of the Navi 3x series, and is expected to be named the RX 7000 series.
The Navi 3x series will change the single-chip design of the past and use a combination of multiple small chips, which is exactly the same as the Ryzen and Xiaolong processors. The top Navi 31 includes a GCD (Graphics Complex Die), TSMC 5nm, mainly graphics processing Relevant units, with six MCD (Memory Complex Die), TSMC 6nm, mainly other units such as video memory controller.
According to authoritative exposure master @Greymon55,The GCD part of the Navi 31 core is a little over 350mm².
This is a full 33% smaller than the 520 square millimeters of the Navi 21 core used by the RX 6900/6800 series, but the latter is a single core, so it lacks direct comparability.
The area of the Navi 13 MCD part is unknown for the time being, and the six will add up to a considerable amount. The total area will almost certainly be larger than that of the Navi 21, otherwise the design will not be separated.
Assuming each MCD is 40mm², the total area will be 590mm², almost the same as the NVIDIA AD102 core, which is rumored to be around 600mm².
It is worth mentioning, however, thatThe Navi 31 core will eliminate some unnecessary and outdated modules, such as XGMI bus for multi-card parallel, GDS (Global Data Sharing), geometry pipeline, scan converter, etc., which can also save a lot of transistors and area.
In addition, the Navi 32 core will also be a similar small chip design, the MCD is expected to be reduced to 4, and the Navi 33 will continue to be a single chip.
