AMD Radeon RX Vega coming with 4GB and 8GB HBM2

VideoCardz offers a bit of coverage of the recent AMD Tech Summit event. The site learned several things, including that Vega will have a smaller footprint that will make it more likely to get adopted in notebooks than AMD's Fiji design. AMD says Vega will allow OEMs to make thinner and lighter laptops capable of rendering the greatest AAA games and VR.

More interesting perhaps is the part that reveals the memory configuration of the Radeon RX Vega lineup. We can expect variants with 4GB or 8GB HBM2:
Herkelman explained that “Vega will use HBM2 that has different capacity stacks”. He then added: “you will see from our board partners different configurations, whether that’s 4 Gig or 8 Gig or those types of memory architectures that will allow you to drive different games and different resolutions based upon what capacity stack they end up using”. That sounds like AIBs will have the option to use single stacks or double stacks of HBM2 memory. So Vega might be available with one or two stacks and that, as you probably know, will affect memory bandwidth, because the more stacks the chip has access to, the higher the bandwidth. But we are yet to see if there will be 2GB HBM2 stacks so that the board partners could still offer 2 stacks with full bandwidth, but only 4GB memory.
AMD hinted at the event that Vega is "just around the corner" but didn't reveal a specific launch date. The company will reveal more Vega tech details as we get closer to launch.
