Overclock3D reached out to AMD and got to hear that besides the US and China, the cards will also be sold in some European countries:
We will be expanding AMD.com sales to more countries, so we expect the 50th anniversary edition will also be available in: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden, and the United Kingdom.This card costs $499, a $50 premium versus the regular Radeon RX 5700 XT. The main difference is that the 50th Anniversary edition has higher GPU clockspeeds.
Sorry we are not offering global availability at this point. We hear you on the desire. The team is focused on expanding into more regions/countries while making sure we can fully support customers.
