AMD GPU core shrinks by 33% But I have six more friends

AMD has already officially announced that it will release the next generation graphics card in the second half of this year, based on the Navi 3X series core, which is expected to be named the RX 7000 series.

Navi 3X series will be a change from the previous single-chip design, using a combination of small chips, similar to ryelong and Xiaolong processors, among which the top Navi 31 includes a GCD(Graphics Complex Die), TSMC 5nm, mainly Graphics processing units. With six MCDS (Memory Complex Die), TSMC 6nm, mainly video Memory controller and other units.

According to @Greymon55, a leading spoiler,The GCD portion of the Navi 31 core is a little over 350 square millimeters.

This is a full 33% smaller than the 520 sq. mm Navi 21 core used in the RX 6900/6800 series, but the latter is a separate core and therefore not directly comparable.

Navi 13 MCD section area is unknown for now, six of them together will be significant, the total area will almost certainly be larger than Navi 21, otherwise the design would not be separated.

Assuming each MCD is 40 square millimeters, the total area would be 590 square millimeters, almost the same as the NVIDIA AD102 core, which is rumored to be around 600 square millimeters.

Unequal scale contrast

But it's worth noting,The Navi 31 core eliminates some non-essential and outdated modules, such as XGMI bus for multi-card parallel connection, GDS(Global Data sharing), geometry pipeline, scan converter, etc., which also saves a lot of transistors and area.

In addition, the Navi 32 core will have a similar small chip design, the MCD is expected to be reduced to four, and the Navi 33 will remain a single chip.
