1. About 19% IPC improvement

2. Higher clock rates (exceeding the advertised frequency this time)

3. Power consumption basically the same

4. Lower latency for most operations (notably 5 -> 4 cycle FMA)

5. Same process node, same die size

6. Slightly higher price

>"...not only performance per watt and performance per dollar leaders, but absolute performance leadership in every segment. We’ve gone into the new microarchitecture and tested the new processors. AMD is the new king, and we have the data to show it."
