I think it's the other way round, with 70% in SSE4 intensive apps and/or 70% in highly synchronized 8-core systems (exact context wasn't clear).

But whatever it is, we have seen the list of integer performance relevant improvements. Even though some people rate it higher than my bet (which is 5% better than K8L for non-compression, non-encoding integer work such as compilation, per core at same clockspeed), nobody has come forward with giving 40% a shot, much less 70%.

Also, keep in mind that the highest clockspeed at launch time is 2.5 GHz. Core2, which is 20% or more faster than K8, comes in 3.0 GHz today, and you can bet that Intel is piling up 3.33 GHz capable dies to throw into some EE when the new AMD launches.

Read my posts earlier in this thread. The 70% is for OLTP, and the 40% is for specfp_rate2000. They made this clear in their virtual IT experience.

As far as I know, Barcelona will not support SSE4.

Intel does not have a 3.0 GHz quad-core available, although they plan on releasing one at some point. You're comparing AMD quad-core clocks to Intel dual-core clocks.

@oldblue: Barcelona will have SSE4A.

SSE4 is different. SSE4 is planned for introduction with Penryn.

It would be nice if they made the names more clear.
