When it comes to reference versions, Asus will be offering two RX Vega 64 versions, one standard Air Cooled Edition (available in Black and Silver Editions) and the RX Vega 64 Water Cooled Edition. The RX Vega 64 Air Cooled Edition will be working at 1247MHz base and 1546MHz GPU Boost clocks while 8GB of HBM2 memory will run at 945MHz (1.9Gbps effective) on a 2048-bit memory interface.
As noted, Air Cooled Edition will be available in Silver and Black Edition, with the Silver Edition, also known as the RX Vega 64 Limited Edition, coming with a silver brushed aluminum shroud and LEDs on board as well as a matching silver metal backplate.
The RX Vega 64 Water Cooled Edition comes with an AiO liquid cooler, most likely from Cooler Master. Thanks to a somewhat higher 265W TDP, the RX Vega 64 Water Cooled Edition comes with a higher 1406MHz GPU base and 1677MHz GPU Boost clocks, while 8GB of HBM2 memory will remain at reference 945MHz (1.9Gbps effective).
In addition to reference versions, Asus also teased that it is currently working on two ROG Strix RX Vega 64 graphics cards, coming in standard and OC Edition versions. Unfortunately, Asus did not reveal any more details as both base and GPU Boost clocks are listed as TBD but we guess that these will carry a custom PCB design and at least a decent factory overclock. According to a couple of pictures at Asus' product page, we do know that the ROG Strix RX Vega 64 will still need two 8-pin PCIe power connectors.
Asus also revealed that the ROG Strix RX Vega 64 versions will use the Asus-exclusive MaxContact GPU cooling technology together with FanConnect II as well as support ASUS Aura Sync RGB LED technology.
Asus did not go into pricing but did say that the reference versions will be available as of August 14th while the custom ROG Strix RX Vega 64 versions will be coming in early September.
