AMD's RX 6600 series may come with 8GB VRAM instead of previously rumored 6 or 12GB

AMD last launched a Radeon graphics card for the desktop market in the form of the RX 6700 XT back in March which means the cut-down RX 6700 and the RX 6600 series are up next and those should be unveiled sometime soon too. Speaking of the 6600 series, today, a bunch of ASRock RX 6600 XT and RX 6600 models have been spotted (via @KOMACHI_ENSAKA) on the Eurasian Economic Commission (EEC)"s website. They have been filed for product registration and the denoted specifications of the models is rather amusing especially when compared to what we have known previously about the 6600 series.

Like Nvidia, AMD, too, seems to be updating the upcoming RX 6600 series" specifications by modifying the memory system of the underlying Navi GPU. In a previous EEC leak, it was seen that both the RX 6700 series and the 6600 series will feature 12GB or 6GB VRAM across a 192-bit wide bus. However, the leak today suggests that AMD has had a change of heart when it comes to the memory layout of the 6600 series and it appears now that both the RX 6600 XT and RX 6600 non-XT will instead pack 8GB memory, possibly across a 128-bit wide memory interface.

AMD may feel that the 8GB memory capacity and the 244GB/s bandwidth provided by a 128-bit wide bus are enough for the performance level that the RX 6600 series will offer. As such, the Radeon RX 6600 series GPUs may pack 64MB of the on-die Infinity Cache.

Aside from the 6600 series models here, there"s also the presence of an RX 6900 XT and a 6700 XT in the mix.
