I am wondering about that interlagos 8 module;i think it will beat current xeon 8 cores, CMT>SMT (this seems to be the case) in terms of raw performance. However, i am not sure about the announced westmere-EX 10 core E7. Interlagos is built on more advanced architecture than magny-cours, but westmere is significantly more powerful than k10.5,
and with SMT, this CPU will have 20 threads, compared to 16 for interlagos. Yes, i do know how SMT works and that it does not double core count...

I also am wondering about the planned terramar CPUs; i think they will beat out the westmere-EXs because they have 10 modules. But what about sandy bridge xeons?
they are only planned for up to 8 core now, but when 10 core sandys are released it will probably be very strong...duh.

Please share your thoughts on these upcoming CPUs.

Sorry, but how do i say something as a discussion, not a question?
oops...

At this point, the only official info we have (courtesy of JF-AMD) is that Interlagos will have 50% greater throughput than Magny Cours, using 33% more cores (16 vs. 12).

So, just like all the Zambezi (desktop version of Bulldozer) vs. Sandy Bridge threads, the ultimate answer is wait and see what the actual benchmarks show. Your wait will be longer however since the server version comes after the desktop version.

I am not getting anything in the server market; i am just interested in whats happening in the server market with bulldozer.

Personally I think Interlagos will do well. AMD really needs it since they have dropped to under 7% server marketshare, and that is where the really big profits are. I'm not in server either but I do find it kinda surprising that Magny Cours didn't turn things around for AMD, seeing as how it was a better value in the 'bang for buck' category. Instead the opposite occurred - AMD dropped from the ~12% marketshare they had a year ago by almost half it seems..

AMD's Opteron has really dropped behind in performance in recent years. Westmere-EP and Nehlahem are considerably more powerful, even in lower density and core counts, than their AMD counterparts. In addition Intel has some key technologies for virtualization that has helped them like VT-d, Execute Disable Bit, and Trusted Execution. In addition, AMD still uses a Northbridge, rather than the onchip integration that Intel has. AMD has a better value, but for performance, Intel still dominates.
