Just interested in seeing how much of a "real world" advantage this HBM memory gives or if its just something that makes a difference in specific benchmarks for the time being.
It will likely be a massive jump, nearly double what current bandwidth is on first gen. It's going to have a positive effect. Also reduction in power consumption which AMD really needs.
Second gen will make 1TB of bandwidth possible
Seen some rumblings that 3XX series is OEM branding only and consumer retail cards will actually be under the 4XX series moniker.
