We'll start with the US, where the Radeon RX Vega 64 is almost impossible to buy, at least not at a reasonable price.
Newegg.com has several Radeon RX Vega 64 graphics cards available and these come from the usual suspects like XFX, Powercolor, and Sapphire, but only as a part of the Radeon Pack.
These Radeon Packs range from US $1,009.97 for RX Vega 64 GPU, Ryzen 1700X CPU and X370 motherboard, all the way up to US $2,045.84 which includes the RX Vega 64 graphics card, Samsung's C34F791 34-inch 1440p curved FreeSync monitor, Asus ROG Crosshair VI Extreme X370 motherboard and Ryzen 7 1800X CPU.
Newegg.com also lists several standalone Radeon RX Vega 64 graphics cards, including Limited Edition silver ones as well as standard Black Edition cards, but all are out of stock and priced at US $599.99, which is US $100 higher than the announced US $499. Newegg.com also lists a couple of Liquid Cooled Edition RX Vega 64 cards priced at US $699.99, but these are out of stock as well.
The situation is no better in other retail/e-tail stores either, as Bestbuy.com also lists a couple of cards at US $599.99/$699.99 and Amazon.com do not have any but you can find them listed from other sellers with a crazy price of US $849.99 or even at US $999.99.
The situation is no better in the UK either and Overclockers.co.uk managed to sell its stock in a matter of minutes at £449.99. Judging by a post from the rather famous store rep, Gibbo, it appears that the official price for the next batch will be set at £549.99, that's £100 higher. Apparently, AMD has been rebating the initial batch for early adopters and this included the black version with no games, while future cards will get copies of Wolfenstein II and Prey.
"Now the good and bad news, the good news is AMD are rebating early launch sales to allow us to hit £449.99 on the stand alone black card which has no games. This is a launch only price which AMD at present are saying will be withdrawn in the near future, when if it happens is unknown, but remember do not be shocked if the price jumps nearly £100 in a few days."
The rest of the Europe is not doing well either as major European retailers are selling the standard RX Vega 64 for €649. The RX Vega 64 Limited Edition is listed at €699 while the Liquid Cooling Edition goes for €749. While this does not sound like a high price to pay for a high-end graphics card, bear in mind that you can buy a custom GTX 1080 11Gbps for as low as €650 or even lower if you get digging.
For that matter, you can find the GTX 1080 Ti for as low as €700 and this one is way ahead of Radeon RX Vega 64, even if you are talking about the praised Liquid Edition.
Hopefully, AMD will get to increase its stock soon and it will push the price a bit down but at this rate, even the price is not working in AMD's favor.
The Radeon RX Vega 56 is scheduled to officially launch on August 28th but we already wrote earlier that you might not see it before September, alongside custom versions of the RX Vega 64. While it was announced as a US $399 graphics card, it could end up priced higher, which could push it closer to the GTX 1070, which is currently listed at around US $430.
In any case, it appears that AMD managed to sell its initial stock but we still do not know how big it was in the first place.
