AMD "Vega 20" with 32 GB HBM2 3DMark 11 Score Surfaces
With the latest Radeon Vega Instinct reveal, it's becoming increasingly clear that "Vega 20" is an optical shrink of the "Vega 10" GPU die to the new 7 nm silicon fabrication process, which could significantly lower power-draw, enabling AMD to increase clock-speeds. A prototype graphics card based on "Vega 20," armed with a whopping 32 GB of HBM2 memory, was put through 3DMark 11, on a machine powered by a Ryzen 7 1700 processor, and compared with a Radeon Vega Frontier Edition.
The prototype had lower GPU clock-speeds than the Vega Frontier Edition, at 1.00 GHz, vs. up to 1.60 GHz of the Vega Frontier Edition. Its memory, however, was clocked higher, at 1250 MHz (640 GB/s) vs. 945 MHz (483 GB/s). Despite significantly lower GPU clocks, the supposed "Vega 20" prototype appears to score higher performance clock-for-clock, but loses out on overall performance, in all tests. This could mean "Vega 20" is not just an optical-shrink of "Vega 10," but also benefits from newer architecture features, besides faster memory.

Of course that home users won't get to taste that hefty 32GB config. Whhaayyyy too expensive and serves very little.
But if they are keeping the footprint the same, maybe not. The Ryzen 2000s are the same physical silicon size as the 1000 series.
Then the consumer/game version can "just" have half the b/w and the mining folks can buy the pricier 32GB/high memory speed one ...
keeping in mind the memory price.
