While it's definitely not something to be positive about, it makes sense. Eight Amd cores ~ 150% of four intel cores. Technically, that's still not winning clock/clock. It mentioned being roughly 20% faster than the 980x which means two extra cores is still only 20% faster. It's much better than PII, but we'll have to see real results.

Bulldozer will be available in three variants - four, six and eight core (or two, three and four module).
To all you people in here, I wish you to ready Amdahl's Law http://en.wikipedia.org/wiki/Amdahl's_law
Its not the cores that are going to count this time, its going to be the microcode thats in it.
I just had a look at that Amdahl's law.....I think I had a brain aneurysm. Ow
If Bulldozer's new instruction set and accompanying compiler
We are working with all of the key compiler vendors to help ensure support of Bulldozer. We are spending a lot of time working with the Open64 compiler folks to make sure that there is support, as well as the PGI Group, GCC compiler and of course, Microsoft®.
AVX will require applications to be recompiled in order to take advantage of 256-bit floating point (either ours or our competitors).
I can’t comment on the ICC compiler, I recommend asking them that question.
We (AMD) work with all of the major compiler vendors to integrate support in. We also have the AMD Core Math Library that can be used when you compile applications, but it is not a compiler.
Here's a very good read for those inclined, AMD's Bulldozer Microarchitecture.
(Page 2, Paragraph 1)AMD first managed to break into the server market in 2003 with the K8, thanks to the 64-bit extended instruction set and system architecture choices such as an integrated memory controllers and on-die interconnects. Intel certainly helped out as well, since the Pentium 4 was a distinctly unfriendly product for servers. AMD eventually hit an impressive 25% market share, and over 50% share in the lucrative 4-socket server market by 2005/6. The key to AMD's success was that they provided exactly what consumers wanted (x86-64 and good server performance), while Intel was distracted with Itanium and the P4. In essence, they found an area where Intel could not (or would not) focus, and then put all their efforts into addressing customer needs and were able to change the rules of the game.
(Page 2, Paragraph 2)AMD's failure here was largely a result of trying to match Intel's superior manufacturing and resources head-on.
(Page 2, Paragraph 4)Philosophically, Bulldozer seems to learn from the lessons of the past decade. AMD is stepping back from the pursuit of single threaded performance, to emphasize throughput.
