Now that’s a first for ASRock … normally, it’s either MSI or Asus first with the EEC filing of new SKUs.
Taken from Videocardz … AMD Radeon RX 6600 series were rumored to launch alongside Radeon RX 6700 non-XT, however, no substantial leaks on either of those SKUs have surfaced in the past few weeks. It does seem we have a new development though.
On EEC (Eurasian Economic Commission) website, there is a new filing from ASRock Europe. The submission features Radeon RX 6600 XT as well as RX 6600 non-XT models, interestingly with 8GB of GDDR6 memory. This might be a confirmation that RX 6600 series might indeed feature a 128-bit memory bus.
Judging from product codes we can distinguish RX 6600 XT Phantom Gaming D, P, and I SKUs. Meanwhile, the RX 6600 non-XT variant would only debut under the Challenger series:
