https://www.techpowerup.com/311452/asrock-quietly-releases-16gb-arc-a770-phantom-gaming-graphics-card Without a formal announcement, or even a product page on its website, ASRock has quietly released a 16 GB version of its Arc A770 Phantom Gaming graphics card. The company's A770 lineup has just the one model—the Phantom Gaming OC, with 8 GB of 16 Gbps GDDR6 memory across the GPU's 256-bit memory interface. The new 16 GB model would be among very few of its kind being released by Intel's board partners, in an attempt to make the A770 an attractive option for those in the market for 1080p thru 1440p capable graphics cards.
Intel's reference designs for the Arc 7 series included the A770 Limited Edition, a card with 16 GB of 17.5 Gbps GDDR6 memory, while the plan originally was for 8 GB of 16 Gbps memory to be the standard memory configuration for the A770. It remains to be seen if the new ASRock Phantom Gaming OC is using 17.5 Gbps memory, or 16 Gbps. The only other 16 GB A770 custom design graphics card available in the West has to be the Acer Predator Arc A770 BiFrost 16 GB. The ASRock A770 16 GB PG was discovered on US retailer Newegg, where it was listed for $329.
I think it's a good decision and at a good price,
