In an ASRock regulatory leak, AMD Radeon RX 7700 XT’s 192-bit memory bus was confirmed.

According to a regulatory filing by ASRock for its forthcoming graphics cards, AMD Radeon RX 7700 XT is verified to have 12 GB of standard memory and a 192-bit wide GDDR6 memory interface. The PowerColor RX 7800 XT Red Devil was massively leaked last week, and we already know that it maxes up the “Navi 32” silicon, allowing all 60 RDNA3 CU, and has 16 GB of RAM spread across the chip’s full 256-bit memory bus. This application offers a glimpse into AMD’s plans for the RX 7700 XT.

The RX 7700 XT is based on the same “Navi 32” hardware as the RX 7800 XT, however it is scaled down and likely created to compete with the GeForce RTX 4070. While one of the four 6 nm MCDs will also be removed, AMD is anticipated to disable some of the 60 CU physically present on the 5 nm GCD, giving the chip a 192-bit memory bus to run its 12 GB of memory. The PowerColor leak has shown that the RX 7800 XT has an 18 Gbps memory speed. It remains to be seen if AMD maintains this pace even for the RX 7700 XT, in which case it would have access to 432 GB/s of memory bandwidth. The RX 7800 XT and RX 7700 XT are anticipated to go on sale within this quarter (before October).
