Lots of AMD news hit the web the last couple of days, it's starting to get a little bit too much! Anyway, VideoCardz reports the latest leaks suggest AMD's gaming Vega cards will be called "Radeon RX Vega 64" and" Radeon RX Vega 56".
The Radeon RX Vega 64 is the full GPU with 64 CUs, this card will reportedly be shown at SIGGRAPH this weekend. It will ship in an air cooled version as well as a liquid cooled edition with a higher TDP, similar to what AMD did with the Frontier Edition. VideoCardz claims the Radeon RX Vega 64 cards will arrive in August but that they won't hit shelves "anytime soon"
There will be no reference model of the Radeon RX Vega 56, this model has 56 CUs and will only be available from AMD's add-in board (AIB) partners. The bad news is this version won't ship until September.
Lastly, there's also an unverified rumor from Reddit about a retailer listing of an ASUS Radeon RX Vega 64, 8GB, HDMI, DPx3 (RXVEGA64-O8G-LIQUID) with an August 2, 2017 availability date. This model reportedly costs 1,115EUR ($1,350) without VAT.
