2. You have two options with the "STARS" core.
...Option 1. Shrink X6 (probably with redesigned Llano "STARS" core, so 3% IPC increase lets say) and increase frequency a tad. Lets say that this arch. will do 4.5 Ghz.
...Option 2. Add more cores, most likely decrease IPC from Thuban or keep it the same using Llano's tweaked core...lets say this arch will do 4.1 Ghz.

Bulldozer. More IPC than X4 in 4 threads or less, "less" distributed per "core" in 8.
no one knows the the exact scaling because its hidden behind NDA.
and if they did stick with PII architecture it would be more than 3% because llano does quite nicely for not having and L3. it would also pack in more true cores. by omitting the extra space used for the second thread of the module, the core itself got bigger with BD, so IPC should be higher or they found ways to waste more space. (btw your option 2 makes no sense, why reduce IPC since they can easily pack in 8 old cores in BDs size, and why would that drop the clocks by 400mhz)

i honestly dont believe in just 6pts for BD at 3.6ghz, and if that is the case its probably on the very low end of the spectrum for how it handles otherwise it would be a step backwards.
