You can already find the AREZ page, within the ASUS website, although it is currently still empty and does not refer to AMD Radeon products, although it could be updated shortly.
We have known for a few weeks that Gigabyte, MSI and ASUS had joined the NVIDIA GeForce Program Partner or GPP, after the monumental anger of the companies over the treatment received with the AMD RX Vega and the supply problems they have suffered with these GPUs. . A few days ago there was talk of the possible creation by ASUS of the AREZ brand, a brand especially intended for AMD graphics cards, reserving the Republic of Gamers for the highest-end NVIDIA graphics cards. This is confirmed with the website published by ASUS.
The ASUS website has been updated and includes a page for AREZ graphics cards, although it is true that at the moment, this page does not show any graphics card of the Radeon family.
AREZ, according to the data we currently have, would suppose the high-end Radeon graphics from AMD, with high-quality heatsinks, but below those intended for the Republic of Gamers family. Apparently different models will come out, with heatsinks the same or similar to those that are mounted on NVIDIA GPUs, but only for this family of graphics.
These are the data that we have so far and that would only affect Republic of Gamers, although there are those who think that it will also affect motherboards, although there is nothing certain. It highlights that on Twitter there is already an account called 'ASUS_AREZ', which dates from January 2018 and that this is possibly not official, since there is nothing to verify it as such. We will see how everything develops and we will be very attentive to new information.
