K8l to have 6mb cache

[Shadowmage]

uh, if you double the number of cores, the IPC should also double, aight?

and if you are talking about K8 vs K8L cores, 40% IPC improvement is not unreasonable but still pretty far fetched.

When doing 2 threads at a time, IPC of the ENTIRE thing would double. AMD's referring to single thread performance, in which the number of cores does not matter (only makes things worse). Increasing the number of cores LOWERS IPC in single-threaded situations due to bus contention, cache coherency misses, etc.

Plus, OoO loads itself adds 40% performance in some extremely limited situations (from Intel tech docs).
