AMD Bulldozer to be launched in 19th September

Oh looks like AMD discovered Netburst architecture - I smell patent war

Having speed demon design does not mean it's like netburst.....
BD will have higher IPC than K10.5, while Netburst had lower IPC than Pentium 3.

It's like AMD decided to make it a speed demon AND a brainiac chip at the same time.
And they designed something superior to hyperthreading (modules).

Actually pushing higher IPC was not the design goal in BD.

Can you elaborate on that? I seriously doubt that BD wasn't meant to be faster clock-for-clock. AMD hasn't pushed real IPC improvements in K10 so that would mean that they would be satisfied with IPC that is comparable to K8 (2003?).

Compared to previous AMD x86-64 cores, project goals reduce the number of F04 inverter delays per cycle by more than 20%, while maintaining constant IPC, to achieve higher frequency and performance in the same power envelope, even with increased core counts.

AMD published 3 articles on Bulldozer at the ISSCC 2011, this one describes in detail the integer cores and scheduler, there was another paper describing the details of the module, sharing, and circuit design and a 3rd which discussed details on the L3 cache design. All three were very interesting reads.

But they did push IPC. It just wasn't the only thing they pushed.
