Sounds like they're basically describing the Kaveri reveal right there. I'm tantalized
The "Role of Java" address sounds intriguing as well. I'm starting to wish I was actually attending the conference.
HSA support , parallel instruction decoder, GCN Hybrid crossfire due to GCN on the iGPU, & improved integer performance most likely,

Steamroller addresses this by duplicating the decode hardware in each module. Now each core has its own 4-wide instruction decoder, and both decoders can operate in parallel rather than alternating every other cycle. Don’t expect a doubling of performance since it’s rare that a 4-issue front end sees anywhere near full utilization, but this is easily the single largest performance improvement from all of the changes in Steamroller.
The penalties are pretty obvious: area goes up as does power consumption.
High Density Libraries
This one falls into the reasons-we-bought-ATI column: future AMD CPU architectures will employ higher levels of design automation and new high density cell libraries, both heavily influenced by AMD’s GPU group. Automated place and route is already commonplace in AMD CPU designs, but AMD is going even further with this approach.
The methodology comes from AMD’s work in designing graphics cores, and we’ve already seen some of it used in AMD’s ‘cat cores (e.g. Bobcat). As an example, AMD demonstrated a 30% reduction in area and power consumption when these new automated procedures with high density libraries were applied to a 32nm Bulldozer FPU
The biggest feature of the CPU core Steamroller of Kaveri is that it has two parallel instruction decoder.
