In response to the update of the Navi 3X specification from 3DCenter.org last week, a reliable and more than once featuring Greymon55 insider indicated that information about the RDNA3 graphics processor tire is incorrect. The insider claims that the Navi 31 will have a 384-bit tire (and not 256-bit), while the Navi 32 will receive a 256-bit (and not 192-bit) tire.

This is an important achievement in increasing memory capacity for the AMD series. If we assume that each of these cards is supplied with the GDDR6 memory of at least 18 Gbit/s, this will give 864 GB/s only for Navi 31, and this is even without taking into account Infinity Cache. The NAVI 32 memory will offer the capacity of 576 GB/s, while the NAVI 33 will remain unchanged with the throughput of 128 bits and 288 GB/s.

Earlier there were rumors that the Navi 31 graphic processor has a 256-bit memory tire and a capacity of up to 32 GB. The 384-bit configuration increases the throughput, and also reduces the number of memory modules, which can lead to the cost of the product and a decrease in cooling ability requirements.

In addition, based on the latest information that the flagship graphic processor RDNA3 will have 1 GCD (graphic computing crystal) and 6 MCD (computing memory crystal), the design of MCM NAVI 31 can differ greatly from previous rumors. Instead of two computing crystals, the multi-chip structure will only affect the memory subsystem (L3/endless cache cache), while the graphic crystal will remain monolithic. The user Twitter @amdgpu_ has prepared a visual demonstration of fresh information:

The specifications of the NAVI 31 graphic processor today are included in the table below the Internet source Videocardz.com. Pay attention, however, that before starting the game a few more weeks, and the incorrect information is still circulating on the Internet, which can (and probably will) lead to confusion as it approaches the launch.
