First mentions of AMD's Radeon RX 6600 XT with 12 GB GDDR6 spotted in EEC filings from ASRock

AMD’s Radeon RX 6000 series could be regarded as a viable alternative for Nvidia’s RTX 3000 series, at least for the high-end video cards. However, Nvidia is still in control of the upper and lower mid-range sectors with the RTX 3060 and 3070 models, but this is just on paper, as the supplies are really tight, and prices are quite far from matching MSRP. Team Red is hit with the same supply problems, and it is clear that AMD is prioritizing availability for the new Ryzen 5000 CPUs, which essentially caused the RX 6700 launch to be pushed back to Q2 this year. As a result, the GPU market is not really in a good place right now, and potential buyers are advised to wait a few months until the supply issues are fixed. Still, AIB makers continue to announce more and more models, even if we might not see any of these available for quite a while. ASRock, for instance, just filed some EEC certificates for some upcoming Radeon cards, including an RX 6700 card with only 6 GB VRAM and an RX 6600 XT card with 12 GB VRAM.

Previous reports were suggesting that the non-XT RX 6700 cards should get 12 GB of VRAM, but it looks like there will be versions with 6 GB, as well. The 6600 XT model, on the other hand, has not been previously leaked by any other AIB maker. It seems to be based on the same Navi 22 SKU with 192-bit memory bus, but it probably has lower clocks and could come with a single-fan cooler. The EEC filing mentions one Phantom Gaming and three Challenger versions for the RX 6700XT and 6600 XT models, while the RX 6700 only gets a Challenger version, suggesting that this particular SKU may not be heavily produced.

AMD is also expected to launch some Navi 23 cards, most likely with the Radeon RX 6500 SKUs coupled with 8 or 4 GB of VRAM and 128-bit bus. Navi 23 is supposed to power Tesla’s upcoming car infotainment systems, so AIB versions could be launched in 2H21.
