Are. But the electricity costs are significant higher in Germany. It is not easy to get payable hardware too, but if you are not too stupid, it is possible. They started long times ago to limit the cards per buyer or to prefer buyers, ordering together with the VGA card also other things like mainboards or CPUs. And a lot of distributors also delivered many cards to their OEM and SI clients (PC builders etc.).
The main problem with Nvidia cards is, that I can buy as pro-miner really easy 6K GTX 1060 6GB directly from the factory without slot panel and cooler to finish the assemby in a 3rd party factory by myself. The AIC get the same price but has no costs for shipping, RMA, import taxes etc. The mining problem is sitting in Asia and Russia. The thing with AMD is a bit different. The AIB get too less chips to keep the production on the possible maximum and can sell this few cards even better than Nvidia products to the miners.
If only a few cards left for a normal shipping I try (as vendor) to deliver into the countries with the biggest margin and smalles import barriers, and this is currently not US. The stupid prices came not from the suppliers, it's home-made by your online shops and stores. Simply take a look, which brands you get in the US and how much brands exists. A lot of this big Asian players like Galaxy or Colorful (both Nvidia) are not available in US. You ever tried to get an inno3D or Manli? I visited a lot of such factories, know the guys from the HQ's and have a lot of good friends in the distribution business. The current situation is not easy. For all.
