Over at the financial analyst day, AMD announced the very first Vega based video card. Called the Radeon Vega Frontier Edition, this model is aimed at professional markets like data science, machine learning and engineering. The card features 16GB HBM2, has a very premium design and has two 8-pin PCIe power connectors.
The Radeon Vega Frontier Edition has FP16 computing power of ~25 teraflops and FP32 computing power of ~13 teraflops. Cards can't really be compared this way, but for a crude comparison, the GTX 1080 Ti from NVIDIA has 11.3 teraflops FP32.
AMD's Raja Koduri specifically said this is the first Vega product and stressed it's a product for pioneers. It's going to be available towards the end of June and based on his language it seems the consumer versions of Vega will launch at a later point. We'll probably hear more at Computex but product availability of Vega consumer parts before the second half of the year is starting to look very unlikely.
The blue card is the Radeon Vega Frontier Edition. Not sure what the watercooled gold edition is.
