All modules also have their own L3 cache, but it is outside the module for some reason. So the CPU does have eight physical, honest to god cores; but not in the sense that we're used to them (as in all cores have all that stuff to themselves) and they're shared in four modules. This is why it's such a departure from the norm and also why it's not HT per se'.

In 128-bit FP mode (like probably 99% of the desktop apps will use) there are 8 cores and 8 FP units.

No, because he doesn't comment on dates.

If you had x-ray eyes, you'd be able to see beyond the first layer. There are 10 more below that one. Just because you don't see what you want on the top layer doesn't mean it isn't there.

Half of my team is taking vacation right now. And if someone wanted vacation on launch day I would never deny it. That makes you a jerk of a boss. You have to do what is best for your people and they will give you their best back.
As for those that say that somehow core counts are just "marketing" and the processor is really only 4 cores. Please explain 2 things:
1. How do you explain the 8 discrete integer schedulers and 8 discrete integer pipelines. No thread can occupy both cores.
2. If you were a customer and you found out that the "quad core", when using only 4 threads, could only use half of the integer pipelines, you'd be pissed, right? If you are only running 4 threads, you only get use of 4 cores, not 8.
