you then hit the problem of a two module chip, being 80% the power if all cores on those modules are being run; so you need even more ghz to match Intel (all estimates of course).

So would the ideal solution, for a powerful desktop, be a 3 module system?
not really. Ipc may be lower than SB, or not, but, BD will be a higher count CPU that SB. for the 8-10 SB core versions you will have 12-16 cores BD. Probably in future BD CPUs we will get 12-16 cores for desktop as well, if they need it.


So, in multi-threaded scenarios, BD will be really good. In single thread scenarios, that penalty you say does not apply anymore, since 1 core in a module is used, not both. The penalty applies only when both of them work. And they would work at 90%, not 80%. A module will be 180% of 2 theoretical BD cores, which would be 200%.
