Nobody can conjure up a working, marketable uarch in half a year, so regardless of how bad these modules might turn out, we'll be seeing more of them.

Then why didn't NETBURST succeed? Why did INTEL take the DOTHAN template for Conroe? Just because a brand new architecture is promoted and performs horribly in the beginning, it does not mean it will be viable in the future. It is a 50 50 chance. If in 3 years this new AMD architecture fails, they will have to design a new one. At the moment AMD pumps more cores and high clocks. INTEL pumped higher clocks and larger cache. To say with certainty that the BD arch will succeed is wishful thinking.

the PPD results make sense when you look at this .net C# app that uses the Microsoft compiler compared to the ppd results of F@H. the spec benchmark uses SSE2 fairly heavily.

Why does the 8120 w/ lower clock beat the 8150 w/ higher clock.

That is odd.

It is within the margin of error the one that I would point out is the hexa-core one not the 4 and 8 core ones

(Also Solidworks only uses 4 threads while the actual application uses more and the i7 990X beats everything in the real world application just want to say that)

8120's seem to have better ipc. At least that's what I got from the benchmarks.

What do you mean? The 8150 has a 500gigajoules(mhz) clock advantage.

Why did the hex core stand out to you?

Various aspects that were new in the Netburst architecture have been carried through to subsequent architectures (though I think the core and core-based architectures were less-based around netburst, and more around the previous gen architecture). But what you're implying is that the architecture that BD is based on is worthless and has no redeeming value for subsequent revisions--why do you assume that?

Agreed. 8120's are just lower-clocked 8150's, yes?

I wonder if it's just an artifact of the benchmark? Something loosely analogous to a cpu benchmark of a gpu-bound game?
